The best top 10 quiet air purifier buying guide is important for you.

Shopping for the right air purifier can be confusing and frustrating. Some air purifiers on the market today actually pollute the air with harmful levels of ozone, a powerful lung irritant that can be especially dangerous to asthma sufferers. Learn about air purifiers and find a safe, effective unit that’s right for your needs with this air purifier buying guide.

Common Household Air Pollutants

Different air purifiers target different pollutants, so it’s important to identify the pollutants you want to eliminate from your home before you buy an air purifier.

Airborne Particles include pet allergen, dust mite allergen, pollen, plant spores, fungi, mold, and tobacco smoke, and they are the most common cause of indoor allergy and asthma attacks. A HEPA air purifier is the best method of eliminating airborne allergens.

Household Odors and Gases include cooking odors, kitty litter, tobacco smoke, various toxins, and gaseous pollutants like indoor pesticides or aerosols. Activated carbon filters are ideal for adsorbing gases and odors that are too small to be trapped by a HEPA filter. “Adsorb” is not a typo; “adsorption” occurs when materials attach through a chemical reaction.

Volatile Organic Compounds (VOCs) are found in a wide variety of common household products: paints, varnishes, cleaning supplies, disinfectants, glues and adhesives, and even new carpet and building supplies. Look for ingredients like benzene, chloride, formaldehyde, ethylene, and toluene. VOCs can cause the following symptoms: irritation of the eyes, nose, and throat, headaches, nausea, and even severe chronic health conditions such as damage to the nervous system. The presence of VOCs can also exacerbate asthma.

Microorganisms include antigens, pathogens, bacteria, and viruses. They’re the everyday germs that make us sick. Mold is also considered a microorganism.

Air Purifier Filter Types

Different air purifier filters target different types of air pollution. HEPA air purifiers are the most popular, and they’re perfect for eliminating household allergens such as dust, animal dander, and pollen, but they’re not very good at capturing ultra-fine particles like viruses or eliminating foul odors or chemical fumes.

Because different air purifier technologies have different strengths and weaknesses, many modern air purifiers combine two or more filter types in the same unit. For example, the Austin Air Super Blend Healthmate utilizes a HEPA filter along with an activated carbon filter to help eliminate odors and fumes. Let’s take a closer look at the different types of filters:

HEPA (High Efficiency Particulate Air) Filters set the standard for air purification. By definition, a HEPA filter removes at least 99.97% of all particles as small as 0.3 microns. HEPA air purifiers were originally developed by the Atomic Energy Commission to capture radioactive dust particles. HEPA filters allow only very small particles to pass through them. Allergens such as pollen, animal dander, mold spores, and dust get trapped in the filter. The main disadvantage of the HEPA air purifier is that you have to periodically change the filter. The main advantage: If it’s HEPA certified, then you know it works well. Not all HEPA filters are created equal. Size matters: the more square feet of HEPA filter, the more particulates it will be able to remove. The size, material, and construction of the actual filter media all play a role in the air purifier’s performance and may account for why one HEPA filter is more expensive than another.

Ion Generators and Ozone Generators create charged particles (ions) and emit them into the surrounding air. These ions combine with impurities (like dust) in the air, forcing the impurities to cling to a nearby surface. Consequently, ion generators often produce dirty spots on nearby walls and floors because they do not eliminate impurities; ion generators simply force impurities to cling to a surface (in the same way that static electricity can make a sock cling to a shirt). Ion generators are the second most popular type of air purifiers, but they both emit ozone, a powerful lung irritant that is especially dangerous for people with asthma and other chronic lung diseases, children, and the elderly.

Electrostatic Precipitators work on the same principle of electricity as ion generators and ozone generators, but electrostatic precipitators capture impurities rather than simply forcing them to cling to an external surface. Electrostatic precipitators, such as the Friedrich C90B Electrostatic Air Purifier, use electronic cells to charge particles within the purifier and immediately trap the impurities on collector plates. The main advantage with this type of air purifier is that the collector plates never have to be replaced; they can be easily washed in the dishwasher. Be aware that some electrostatic precipitators also generate ozone.

Charged Media Filters work the same way as electrostatic precipitators, but they collect particles on fiber filters instead of plates. The advantage of these filters is that they are able to collect very small particles, sometimes as small as 0.1 microns, through a combination of a filter and an electrostatic charge. The disadvantage is that, like the electrostatic precipitator filters, charged media filters lose their efficiency fairly quickly, and they can require more frequent filter replacements compared to a HEPA air purifier. These types of units can produce ozone, but the better ones on the market do not. If you are going to purchase this type of air purifier, make sure that it does not produce ozone. The best air purifier in this category is the Blueair air purifier.

Activated Carbon Filters are rarely used alone to purify the air, but they are often used in conjunction with other filters. Activated carbon and charcoal filters excel at adsorbing odors and gases and neutralizing smoke, chemicals, and fumes. “Adsorb” is not a typo; “adsorption” occurs when materials attach through chemical attraction. Activated carbon has been treated with oxygen, opening up millions of pores in the carbon. There are so many of these tiny pores that one pound of activated carbon has a surface area of 60 to 150 acres. This huge surface area makes it ideal for adsorbing gases and odors. These chemicals and gases are too small to be trapped by a HEPA filter, but they bond to the enormous surface area in the activated carbon. The bigger the carbon filter, the more chemicals it will be able to absorb and the longer it will keep on working. When it’s full, it can’t adsorb any more and has to be replaced. Impregnated carbon filters contain an additional chemical (a “chemisorbent”) to eliminate certain chemicals like VOCs.

Antibacterial and Germicidal Filters eliminate bacteria and germs. The IQAir Clean Room H13 HEPA Air Purifier, for example, utilizes a HEPA filter treated with agents to kill airborne microorganisms. Other air purifiers, like the AllerAir 4000 EXEC UV Air Purifier, use a UV lamp to kill germs. As antigens and pathogens pass over the lamp, it emits ultraviolet waves which alter their DNA, making them sterile and harmless. Air purifiers with UV filters are often used in sterile environments such as hospitals, kitchens, daycares, and labs. In residential use, they are great for controlling mold. If you are someone who gets sick often, an air purifier with a germicidal filter may be just what you need to give your immune system that extra boost.

Pre-Filters remove large particles prior to primary filtration and come with nearly all air purifiers.

Other Factors to Consider Before Buying an Air Purifier

Area Coverage – Make sure the square footage listed for the air purifier is about the same or slightly greater than the square footage of the room where you intend to use it.

Air Changes Per Hour (ACH) – This number, also known as the ACH rating, tells us how frequently the air purifier can exchange all the air in a given room. For example, if the purifier has a ACH rating of 6 for a 20′ x 20′ room, then it is capable of exchanging all of the air in that room 6 times every hour. If you have allergies or asthma, you want an ACH rating of at least 4 and preferably 6 or 8.

Clean Air Delivery Rate (CADR) – The CADR, calculated by AHAM (The Association of Home Appliance Manufacturers), tells us not only how much air is purified, but also how well it is purified. Air purifiers that have been tested by AHAM should have the AHAM Certified seal and CADR numbers for three pollutants: tobacco smoke, pollen, and dust. The higher the CADR rating, the more effective the air purifier is against that pollutant. CADR ratings are calculated impartially and recognized by the Environmental Protection Agency and American Lung Association.

Price – Air purifiers range from affordable $100 air purifiers for small spaces to fully loaded $1,000+ air purifiers for large rooms.

Filter Replacements – If you’re buying a HEPA filter, don’t forget to check and see how much replacement filters will cost. If your unit includes both a HEPA filter and a carbon filter or other combination filtration media, they will probably need to be replaced separately, and may last for different periods of time. This can be a hassle, particularly if they are difficult to access.

Noise Level – Some air purifiers, such as the Blueair units, are extremely quiet, while others can be quite loud when operating at high power. If possible, ask for a demonstration before you buy your air purifier.

Energy Usage – Like all appliances, different air purifiers use different amounts of energy for operation. Unlike most appliances, air purifiers run continuously, so you’ll want to consider your utility bill before buying an air purifier. If only volts and amps are listed, simply multiply the two: volts x amps = watts. Typical mechanical air filters can use anywhere from 50 watts on low to 200 watts on high. (For comparison sake, a typical lamp uses about 60 watts, while a typical computer uses about 365 watts).

Air Pollution – Some air purifiers pollute the air with ozone, a powerful lung irritant that is especially dangerous for asthmatics, children, and the elderly.

Extra Features – These are the bells and whistles. They can make your air purifier a lot easier to use. On the other hand, they can also significantly up the price on an air purifier that isn’t really all that much better than the next one. You simply have to decide which features will make your life easier and which ones just aren’t worth the extra cash. For example, a filter change indicator light lets you know when to change the filter, and handles or casters are important if you plan on moving your air purifier around a lot.

Manufacturer’s Reputation – A manufacturer’s reputation and the experiences of past customers deserve consideration in your decision. Certain manufacturers and products are highly respected in the industry for a reason – and the same goes for products which have garnered less respect. Check out customer reviews to get a sense of the reputation.

Warranty – A five-year warranty is a good one. A ten-year warranty is even better! Take into account what the warranty covers – motor, fan, electrical components? Also, find out if certain customer actions will void the warranty. Some manufacturers will void the warranty if the customer does not purchase replacement filters over the recommended time period; this can be inconvenient if you plan to run your air purifier less often or if the air in your home is cleaner than average.

Well,according to above content,you should know clearly about the air purifier buying guide for your family.

Olansi people will tell you why it is needed to choose a best whole house air purifiers and cleaners, central air purification for home healthy.

Before purchasing an air purifier for your home, it would be beneficial to do a little online research in preparation for your trip to the store. Make a list of the things you and your family would like in an air purifier, and bring this list with you to the store. This way, you’ll be able to match a purifier to your specifications far more quickly and accurately. You will also find it far easier to ask questions and stick to your budget if you know what you are looking for ahead of time.

For those who suffer from seasonal allergies, asthma or other respiratory illnesses, breathing polluted air on a regular basis can be painful or even cause further degradation of health. Even those who are otherwise in good health can develop health problems over time. One way to avoid this type of debilitating illness is installing an air purification system in your home.

Unlike single-room air purifiers, whole house air purifiers can be installed on your home’s ductwork, connecting the purifier to your furnace or central air. The whole house air purifier would then be able to cleanse your entire home, functioning in correlation with your other air circulation systems. In addition, whole house air purifiers are placed in areas of the house where you will have limited visibility of the unit. Although they are larger than single-room air purifiers, whole house air purifiers use powerful ionization and oxidization systems to cleanse the air in your home.

While the initial monetary output for a whole house unit installation may seem daunting, the combined cost of multiple single-room units in one home is considerably higher. Over time, the filters in all of the smaller units would need to be changed and cleaned, while a whole house air purifier only requires one filter change every few months — saving you time and money. In addition, whole house air purifiers require very little in terms of maintenance costs; with regular servicing, they can last up to 20 years. Even if you forget or simply don’t have the cash for unit upkeep, your whole house air purifier model will still last considerably longer than single-room air purifiers: that’s the difference in quality and sturdiness.

After your whole house air purifier has been installed, not only will you breathe clean, fresh air, but you’ll also feel much healthier. With only a little required maintenance and a filter change every few months, a whole house air purifier will certainly provide you and your household with a convenient and aesthetically pleasing option to purifying your home’s air.You can pay a visit to Olansi website https://www.olansi.net for more info about whole house air purifiers.

Olansi is one of the top 10 best selling air purifier in china.An air purifier or air cleaner is a device which removes contaminants from the air in a room. These devices are commonly marketed as being beneficial to allergy sufferers and asthmatics, and at reducing or eliminating second-hand tobacco smoke. The commercially graded air purifiers are manufactured as either small stand-alone units or larger units that can be affixed to an air handler unit (AHU) or to an HVAC unit found in the medical, industrial, and commercial industries. Air purifiers may also be used in industry to remove impurities such as CO2 from air before processing. Pressure swing adsorbers or other adsorption techniques are typically used for this.

But how to choose a suitable air purifier for the winter?

Olansi people have the best air purifier buying guide to tell you how to choose the best air purifier for dust removal.

air purifier

air purifier

The best air purifier for dust on the market utilizes HEPA (High Efficiency Particulate Air) filters. Effective HEPA filters can remove up to 99.97% of airborne particles, helping you effectively control and reduce dust inside your home. Used fabric softener.

If you are looking to buy an air purifier, do not miss the following buying guide.

A few years ago we had to resign ourselves to accepting the conditions imposed on us by nature itself, which also controlled the atmosphere that reigned inside our houses.

We spend 90% of our time in closed spaces, so defying it and controlling the particles suspended inside these spaces is practically indispensable for people suffering from allergies and asthma.

The cleaners of the interior of the rooms of a home are the purifiers of air. They are a kind of robots, more or less autonomous, that connected to the electrical outlet are able to quantify and manipulate – to the point of eliminating or eradicating – the dirt of the environment that reigns in the room in which they are.

1.The importance of the capacity

When we buy an air purifier, we can see that one of its specifications is that of the cleaning capacity. It comes given in square or cubic meters, depending on the brand. This information indicates the maximum size – in surface or volume, respectively – of the room to be cleaned so that the result is optimal; that is, unbeatable according to the characteristics of the purifier.

2.Noise

And here we come to one of the key points of this guide. It is what will determine how annoying an air purifier is, without any doubt.

One aspect to consider is whether we intend to have the purifier connected in our bedroom while we are sleeping. If we are very light of sleep we can have problems to keep us asleep, so it is very convenient to consider the opening hours.

3.Filters

The filter is like a motor to your car. It is what marks its quality, although up to the moment there is not a huge variety as happens with the motors of the automobiles. The filter par excellence of air purifiers is HEPA.

4.The Importance of Power

The power of a purifier is closely related to its capacity. The more power we have, the faster it will clean room air the size indicated by the specifications.

If the purifier is located in a larger room, the power will be a less relevant and ultimately later in accomplishing its task, this will not be to leave the perfect room, but to leave as clean as possible.

If the air purifier is instead placed inside a smaller room than the instructions dictate, the power can be reduced to perform the same work as in a larger room: clean the room thoroughly.

5.Suitable dimensions

What dimensions are appropriate?

With air, purifiers happen that as a rule, the larger they are, the more work capacity they usually have.

It is not a determinant factor to evaluate the quality of a purifier, but it is with regard to the decoration of our house and comfort of transfer.

 

6.Speeds

Almost all models have built-in speeds of operation. They serve to regulate the speed with which we want our air purifier to act. We often meet with night mode, with turbo mode and intermediate mode. Of the intermediaries, we will say nothing because the name says it all.

7.Ionizing function

The ionising function is also present in almost all air purifiers, although there are some low-end ones that still do not have it. What it does is emanate negatively charged ions, which through chemical bonds are joined to positive particles generated by electromagnetic devices, normally the most harmful to our health.

8.Coal layer active

The active carbon layer is responsible for removing the odoriferous particles. The carbon of this filter is treated with oxygen, which causes the opening of many pores between its atoms. These pores, when releasing the molecules, exert of absorbent and are the cause that the odours, the gases and the liquid contaminants disappear of the environment.

 

9.Programming air purifier- The programming

Interestingly, not all devices have a function as a priori simple as programming in advance. To us, it seems like a most useful application when we have decided to sleep with the air purifier on, as well as when we want the environment to be clean when we get home from work.

10.Autonomy – The best of the best

This is the element that only the high-end purifiers have. It is tremendously comfortable because it allows the device to operate independently without having to worry about the bill of light

Here’s why you need an air-purifier for a healthy and germ-free home if you’re living in Delhi

Here’s why you need an air-purifier for a healthy and germ-free home if you’re living in Delhi

The war for clean air has been heating up all over the country in the recent past. While the problem of rising air pollution remains to be one of the most crucial health concerns in India, it is only recently, with the series of chaos and debates that it has finally dawned upon us about the ill-effects of polluted air. Though people are now recognizing that both outdoor and indoor air pollution is hazardous to the physical, mental and emotional wellbeing of any person, one of the pertinent issues prevailing in the country is the lack of awareness among people about the availability of right air purification technology.

With the drop in temperature due to winters, a host of airborne pollen and household allergens have a way of finding their way indoors during this season causing infections and diseases. In addition to pollen, closed and unventilated homes can breed dust mites, molds, pet dander and other household irritants. Since, in our regular hectic lifestyles where we cannot afford to fall ill or have long sick days it is vital to breathe the right quality of air indoors. Therefore, air purifiers have now become a need for a healthy living. Also, since the market is flooded with a variety of air purifiers, it has become equally important to select the right one that ensures the air you breathe is healthy and safe.

One can follow the below mentioned basic tips and examine a few things while making a choice to keep your home healthy and germ-free.

• Emphasize on the filters: Check the specification of the air purifier to see whether it has a  (high efficiency particulate air) filter that are highly efficient and capable of removing up to 99.97% of micro particles. There are many products in the market which say HEPA-like filters, avoid buying those.

Delhi smog and air pollution remains very high

You know you’re living in Delhi if your eyes burn, your throat is sore and your chest feels heavy. It’s been four days since Diwali night, however the cover of toxic air doesn’t seem to be lifting. The blame lies partly with the excessive fireworks display on Diwali night and partly with the farmers in Punjab who refuse to pay any heed to the environment and continue burning the crop stubble left behind after harvest.

There’s also the failed attempt by the Delhi government in vacuuming the dust off our streets whicdelhi air pollution, delhi pollution level, pollution in delhi, pollution in new delhi, air pollution in delhi, delhi smog pollution, delhi pollution news, Air Purifier, Air Purifier india, air pollution in delhi statistics, delhi air pollution report, delhi smog, delhi pollution level today, delhi pollution level 2016, air purifier for home, air purifier news, delhi news, India Newsh continues to be a major source of fine particulate matter available freely in the air. Combine expert medical advice that urges people to leave the National Capital (if they want to be healthy) along with more experts who say that the PM levels are unlikely to go down over the next few days, we’ve got ourselves a real fix here. While the government scrambles to figure out a plan to tackle the problem in the long run, what you can do immediately is get yourselves a few air-purifiers for your home and car. However, don’t go out and just buy any purifier, simply because it has a large price tag or a fancy brand name on it. Here are the essentials to look out for.

HEPA Filters

All modern air-purifiers feature High Efficiency Particle Arrestance (HEPA) Filters. These filters are generally rated to trap particles as small as 0.3 microns (the breadth of a human hair is about 50-150 microns). The particulate matter we are most concerned with is rated PM2.5 (particles that are 2.5-10 microns in diameter) and PM10 (10 microns or more in diameter). Therefore, any air purifier with a HEPA Filter should be able to remove much of the particulate matter from the air, but that won’t be enough.

When evaluating air-purifiers, having a HEPA Filter is a pre-requisite. Nowadays, there is some controversy over the effectiveness denoted by the word HEPA, so to be on the safe side, ensure that you buy an olansi air purifier that mentions having both a TRUE HEPA filter and a 0.3-micron rating at the very least.

 

Many have brought the purifiers for either children or senior citizens.

The record-breaking pollution levels have spiked the sales of air purifiers and masks in Indirapuram in the past three days. Many have brought the olansi air purifier for either children or senior citizens.

OLS-K06B

While many people bought these items as a preventive measure before the festival of lights and crackers, there has been a significant rise in sales post Diwali as well.

According to Snapdeal, the category has seen an overall three-fold increase in demand this year compared to the same time last year.

“Between pre-Diwali and post-Diwali, we have already seen a seven-fold increase in the number of air purifiers and masks sold on Snapdeal,” it added.

Interestingly, the city-based portal has curated a special store for the category and is expecting a 10-fold surge in orders placed for air purifiers.

Consumers are also opting for air purifiers on the go. Unit sales of car air purifiers in the first 5 days of November was 140 per cent more than that seen in the month of October for the devices on Snapdeal.

The city’s air quality has steadily worsened over the years, a result of pollution from vehicles and industrial emissions.

Apart from atmospheric dust, burning of crop stubble in farms also contributed to the thick cover of hazardous haze that has been shrouding the city for nearly a week.

The air quality have levels of harmful PM 2.5 particles hovering at dangerous levels, something that has been seen in cities like Beijing.
These fine particles less than 2.5 micrometres in diameter are linked to higher rates of chronic bronchitis, lung cancer and heart disease.

 

Trying to keep the dirty air away from their children and older parents.

NEW DELHI — For days, many in Delhi have been living as if under siege, trying to keep the dirty air away from their children and older parents.

 

But it is not easy: Open a window or a door, and the haze enters the room within seconds. Outside, the sky is white, the sun a white circle so pale that you can barely make it out. The smog is acrid, eye-stinging and throat-burning, and so thick that it is being blamed for a 70-vehicle pileup north of the city.

If in past years Delhi’s roughly 20 million residents shrugged off wintertime pollution as fog, over the past week they viewed it as a crisis. Schools have been ordered closed for three days — an unprecedented measure, but not a reassuring one because experts say the concentration of pollutants inside Indian homes is typically not much lower than outside.

A family rode a scooter during heavy smog and dust in Delhi on Sunday.

Levels of the most dangerous particles, called PM 2.5, reached 700 micrograms per cubic meter on Monday, and over the weekend they soared in some places to 1,000, or more than 16 times the limit India’s government considers safe. The damage from sustained exposure to such high concentrations of PM 2.5 is equivalent to smoking more than two packs of cigarettes a day, experts say.

 

“There is so much smog outside that today, inside my house, I felt as though someone had just burned a few sheets of paper,” said Amaan Ahuja, one of dozens who shared their families’ experiences in response to a request from The New York Times.

“You can literally see smoke in the air, and when you breathe, you can smell it, too,” he said. “We are trying to keep the kids indoors with all the windows closed.”

Another reader, Tulika Seth, described her family’s life over the past week as “unnatural and disturbing.”

Asked where she lived, she responded, “a gas chamber.”

To understand the health consequences of the dense smog that settled over India’s capital over the past week, scientists are looking back decades in search of a historical precedent:to the 1952 Great Smog of London, which is believed to have caused as many as 12,000 premature deaths.

In that case, a layer of dense pollution — caused largely by emissions from burning coal — dissipated after four days, when the weather changed. But an uptick in deaths continued for weeks afterward, so shocking the public that it spurred a wave of environmental regulations.

Delhi’s chief minister on Sunday announced a series of emergency measures, including a five-day moratorium on construction, a 10-day closure of a power plant and a three-day closure of about 1,800 public schools.

On Monday, the city government released a list of health guidelines, advising citizens to wash their eyes with running water and to go to a hospital if they were experiencing symptoms like “breathlessness, giddiness, chest pain and chest constriction.”

But experts said mitigating the conditions would have required policies to be put in place months ago.

“These are all decent emergency measures, but they’re not solving the long-term problem,” said Bhargav Krishna, who manages the Public Health Foundation of India’s environmental health center.

“The best we can hope for, in a way, is to plan for next year,” he added. “This year is almost a washout.”

Changing weather conditions are likely to disperse the dense cloud of pollutants over the next few days. But they will also bring the beginning of the widespread burning of trash, including plastic and rubber, for warmth by Delhi’s poor.

Among the persistent problems for policy makers is that the sources of the pollution — vehicles, construction, crop burning and holiday fireworks —

fall under the authority of half a dozen city, state and federal government bodies, which are in some cases at odds with one another politically, Mr. Krishna said.

“Where exactly is the responsibility for implementing these plans?” he said. “At whose desk does this all lie?”

He added, “The diffuse nature of power means that it is easy to pass on responsibility to others.”

Public anger over Delhi’s air is more palpable than in previous years, and people are more likely to identify pollution as the cause of their health problems.

Anumita Roychowdhury, who runs the air pollution program at the Center for Science and Environment, said that sense of urgency would have to be sustained if the city were to impose lifestyle changes, including restraints on car travel.

This has to translate to very strong support for very hard decisions,” she said. “All soft options are over.”

First, though, people here must get through the next few days.

Sherebanu Frosh, who lives in Gurgaon, south of Delhi, said she and her children were “cowering by our air purifiers,” which had become overloaded with the concentration of particles in the air.

“So we’re putting both our purifiers in one room and spending the day there,” she said. “If we leave, we wear masks.”

Jessica Farmer, whose children attend the American Embassy School in Delhi, said she had moved five purifiers into three rooms of her house, but the concentration of PM 2.5 in some places remained at 300, five times the W.H.O. recommended limit.

“It is as though we are under siege,” Ms. Farmer said. “We can’t go outside, to malls or movies where the air is not purified.

“How can one live like this?”

The battle to buy a smog mask in India’s pollution-Olans two products you deserve

My own mother usually kicks off our phone conversations by asking, “Have you eaten yet?” But since I m

oved to New Delhi three weeks ago, she has adopted a new opening question: “Have you bought a mask or air purifiers?”

This weekend, I finally relented and bought a face mask designed to protect against pollution particles. I did it for mom. But I also did it because Delhi’s air has reached levels of toxicity that are putting my asthmatic lungs — really anyone’s lungs — in serious danger.

I wasn’t the only Delhi-walla looking for protection.

When I arrived at Nirvana Being, a small shop in the city’s upscale Khan Market that sells anti-pollution products, there were at least 15 people in line to buy face masks. By the time I made my purchase, there were around 20 more.

In depth: Delhi’s fight for clean air

“When we opened that store people thought I was nuts,” said Jai Dhar Gupta, who heads the store’s parent company. “Now we have lines for 10 hours a day.”

Gupta declined to share exact sales figures, but he claims to have sold more masks in the past 10 days than he sold all of last year.

It’s a scene playing out all over the city — in pharmacies, electronics stores and anywhere else that sells masks and air filters that might provide relief.

Already notorious because of its toxic air, pollution in Delhi has skyrocketed over the past week. Measurements of dangerous particles taken at the U.S. Embassy in Delhi put the city’s Air Quality Index (AQI) at 999 on Monday, off the standard chart, which finishes at the “hazardous” level of 500.

The suffocating smog has reduced visibility in the city to just a few meters, and the Delhi government has closed schools for at least three days.

The dire situation has taken anti-pollution devices and attire from niche to mainstream, with a report by research firm TechSci predicting that the air purifier market in India will go from 40,000 units to 100,000 units over the next year and generate over $200 million in revenue by 2021.

So,If you don’t want to wear a mask at home/office/school.You should buy a air purifier for home/office/school to ues.

Buying an air-purifier: HEPA filters are a must, as is the right size

(Surgical masks, despite their popularity in Delhi these days, are useless against the smog and pollution haze.)

The blanket of toxic air over Delhi — the product of road and construction dust, vehicle emissions, crop- and waste-burning, smoke from Diwali fireworks, and the currently prevalent cool, still atmospheric conditions – doesn’t seem to be lifting. While the government struggles to get moving on an effective long-term plan to tackle the problem, many residents have begun to invest in air purifiers for their homes and cars. Here’s what to look for while buying one.

All modern air-purifiers feature High Efficiency Particulate Arrestance (HEPA) filters. These filters are generally rated to trap particles as small as 0.3 microns – for perspective, the thickness of a strand of human hair is about 50-150 microns. Therefore, any air purifier with a HEPA filter should be able to block out both PM 2.5 (particles that are 2.5-10 microns in diameter) and PM 10 (10 microns or more in diameter) particulates. To guard against possible confusion over what the acronym ‘HEPA’ denotes, it is a good idea to ensure the air-purifier mentions having both a ‘True HEPA filter’ and a rating of at least 0.3 microns. Some companies like Sharp claim their air-purifiers also neutralise germs — including e-coli and tuberculosis bacteria, H1N1 virus and even fungal spores — by mimicking the naturally occurring positive and negative ions in the air. You could buy a regular air-purifier and pair it with a standalone ionizer for the same effect.

Size matters

An air-purifier’s effectiveness will depend greatly on how big your room is, how much air the purifier can circulate, and how much ‘outside air’ gets in at any given time. Most manufacturers say what size of room their purifiers would be effective for, but a thumb rule is to buy one bigger than the rated room size. So, for a room that is 300 sq feet in size, it is best to purchase an air-purifier that can handle at least 400 sq ft. Also, because the extraordinary density of the current pollution and the volumes of air flowing in and out of the room will lower the purifier’s effectiveness, it is advisable to shut all doors and windows.

Delivery rate

The size match relies on an aspect of these devices called the Clean Air Delivery Rate (CADR), which denotes how much air can be purified of all its particles, expressed in cubic feet per minute. Normally, there are three CADR ratings, one each for Smoke, Pollen and Dust, as these three particles tend to vary in size and thus are filtered out at varying efficiencies.

When purchasing an air-purifier, insist on getting all three numbers, given that smoke particles measure 0.09-1 micron, and are the hardest to filter out effectively. The higher the CADR number, the more effective the air purifier is for a given size of room.

Pollution masks

The surgical masks some people have been wearing are useless. They don’t seal your mouth and nose, and don’t filter out anything. Most pollution masks with a N99 rating (filtering 99% of particulate matter) will filter out dust particles, but will not do anything about the fumes.

Since desperate times — such as those prevalent in Delhi these days — call for desperate measures, a 3M face mask, paired with a P95 filter and an organic vapour cartridge, is an effective solution. This combination allows even chronic asthmatics to move around outdoors without problems. In fact, the mask filters out odours from cigarette smoke, vehicular emissions and even garbage dumps.

A less bulky option could be a mask from Respro, a UK-based company that makes neoprene masks that are equally effective. Respro’s Techno mask is ideal for the current situation as it comes with a P99 filter (rated to 0.3-micron efficiency) along with an organic vapour filter built in.

Fresh hot words: haze influence you?

Recently, much of the country has suffered haze weather, the northeast, North China, central China area have undergone severe haze weather. In late October, haze enveloped Harbin, forcing the bad weather in the primary school, kindergarten classes (suspend class). Recently, the Beijing Municipal Meteorological Bureau (Weather Bureau) within a week released 4 haze early warning I do not know, whether serious haze will affect Beijing’s bid for the 2022 Winter Olympics (Winter Olympic Games)? Winter day, Shanghai AQI Shen childe was bursting with haze volts. The children have been the ten volts haze weather affect? Today and learning together with “d haze related English words!

In English we usually say “haze” the haze, haze is composed of fog and haze, the primary pollutant PM2.5 haze (particulate matter 2.5) refers to the atmosphere in diameter less than or equal to 2.5 micron particles, is particulate matter into the lungs. Affected by haze influence, most areas in serious air pollution, here, small D to introduce the two often appear in weather reports in terms of AQI and api.aqi refers to the “air quality index” (air quality index), API refers to the “air pollution index” (air pollution index), API index is larger, that air pollution is more serious. In English we can also express the haze weather using “airpocalypse”, the word is “air” and “Apocalypse” spelled into the smoke, dust, pollution caused by extreme weather interaction by the air , can be translated as “the end of the air, the end of the air”.

Severe haze weather caused anti-dust masks (anti-dust respirator/mask) (sell out), almost out of the air purifier are also sold out of stock. Some time ago rumors haze weather will affect the reproductive capacity (reproductive capacity) (Khan)?! is it true? The expert response, even if there is also not too much. At present, the haze of harm to human health or the most direct increase of respiratory system disease (respiratory system disease) incidence. So in the face of haze, we want to minimize out at home, remember to close the window! Small D (foodies) are recommended chowhound eat some Qingfeihuatan food, for example pear (pear), orange (Orange), black fungus (black fungus) (snow fungus), tremella. Do you remember?
