Recently, the Shanghai Consumer Protection Committee issued 20 air purifier comparison test results of different samples, the huge gap between the actual cleaning ability.

Among them, the amount of clean air formaldehyde maximum and minimum difference of up to 70 times in recent years, the country and more frequently encountered invasion of haze, air quality is the topic, the air purifier is also more and more consumers of all ages. “99.95% to pm0.1 automatic purifying harmful particles” can filter out small to 0.02 micron particles “and” effective removal of formaldehyde and other harmful gases, sulfur dioxide removal efficiency is more than 99%.

The air purifier function, business promotion more and more, almost equal to anything, but the actual situation how? Let’s take a look. The comparative test of the air purifier to buy 20 mainstream brands, including 12 in the purchase of large department stores, 8 in the purchase of electric flat Taiwan, the price ranging from 699 yuan to $18600 per unit.

Clean air quantity discount

Clean air volume (Cadr) with larger values for the larger, in the same space, purifying particles faster. In our country, gb/t18801-2015< air purifier > specified in the application area = particulate clean air volume x (0.07 ~ 0.12), Shanghai local standard “applicable area = particulate clean air volume x 0.1”.

The test results showed that 20 samples of the measured particles Cadr the lowest value of 77 cubic meters / hour, up to 569 cubic meters / hour, for the minimum area of 9 square meters, a maximum of 68 square meters. But the product function of some enterprises is much larger than the nominal value and the measured value, an air purifier for nominal area 46 square meters, measured for an area of only 23 – 39 square meters.

PM2.5 purification capacity gap

The index refers to the air purifier to PM2.5 (test particle size of 0.1 mu m-2.5 mu m) purification parameters performance. The testing results show that the 20 samples of PM2.5 clean air volume up to 518 cubic meters / hour, the lowest is 69 cubic meters / hour, more than 7 times.

Formaldehyde purification ability is not satisfactory

The purification efficiency of formaldehyde in the air purifier is refers to the nominal area of, after 1 hours of operation, the removal efficiency of formaldehyde. The higher the number, the use of the same size in space, formaldehyde purification faster. Test results showed that 20 samples formaldehyde amount of clean air, the highest for 282 cubic meters / hour the lowest, 4 cubic meters / hour, 70 times the difference. An air disinfection machine nominal value was 47m m3 / h, the measured value is only 37 cubic meters / hour. The comparative test data analysis found that 17 has a nominal formaldehyde purification function of the samples, according to the t310106001-c001-2015 (apiac/lm01-2015) “with nominal gas purification ability of the air purifier, should not be less than C the purification efficiency of the measured values (C 35% ~ 50%)” requirement, the purification efficiency of grade 6 class A, B grade 7, C grade 4,

 

Need to buy the filter need to change

Choose according to their actual needs, and not the more the better, should choose their own products. Such as: haze prone areas can be strong purification products focus on PM2.5 particles, indoor decoration can be strong new products focus on the purification of volatile organic compounds such as formaldehyde and toluene.

Pay attention to particulate clean air volume (Cadr) and the applicable area. For each area of the air purifier should have a nominal particle Cadr and suggestions.

Suitable area generally refers to the air purifier can be achieved in the final 2.4 meters storey indoor, at least more than 80% removal of particle pollutants, can use the indoor area, can be obtained by the “nominal particle Cadr x 0.1” calculation.

Olansi air purifier is the best choise in china now.

 

Indoor air purifier filter PM2.5 really useful

Indoor air purifier filter PM2.5 really useful 

01

Indoor air purifier filter PM2.5 is really useful? Enter the market from the beginning of this air purifier, voices of doubt has jumped out of it in the end how to use effects? Please air purification expert Egisen for everyone to answer it.

Air purification experts said Egisen, the main material of air purifier filter PM2.5 is HEPA filter, is to open the air purifier is seen as shutters like dense network, it can block PM2.5 in the air, so that the air filter can eliminate indoor smoke, dust and microorganisms and other pollutants. If long-term use of air purifier consumers should be able to feel the air quality significantly improved.

The air purifier on the market mainstream is the passive adsorption filtration type. The working principle of passive air purifier is mainly used fan to draw air into the machine, and then filtered air through a built-in filter, to filter dust, eliminate odor, remove microbes and so on. Net type air purifier is the use of HEPA filters. Activated carbon filter, photocatalyst, ultraviolet disinfection method to clean up the air and HEPA filter filter dust particles, mainly activated carbon and other substances are toxic and harmful substances such as odor absorption.

But the air purifier is used for a long time, particle filter attached to accumulate, not clean to use will cause two pollution. Suggestions about 3 months to check a filter, if found uneven color, dark yellow, should be replaced; if the air purifier wind blowing smell it should also consider replacing the filter.

Customer service in the visit, we found that many consumers in order to save costs is not in accordance with the requirements for the filter, or occasionally to open up, so the air quality comparison and not intuitive understanding, it is difficult to affirm air purifiers use value.

In fact, a high quality HEPA filter net price is about several hundred yuan (different brands and models vary), according to an average of 6 months of daily use cost accounting, HEPA only a few dollars, compared with our health, the number of absolutely not huge. Suggestions to keep better air quality consumers should be the long-term use of air purifier.

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.

 

Enter the Clean Air Machine/Air purifiers

The post-Diwali pollution has left Delhi dealing with the worst smog it has ever experienced. As the pollution results in watering eyes and tightness in the chest, many have now taken to buying air purifiers in the hope that it would provide some guard against lung-­damaging conditions.

As pollution levels soared manifold beyond the prescribed limit, sales of devices for pur­ifying indoor air also jumped 50 per cent in the first week of November. Suvendu Mazumdar, national product manager of Spark international, one of the leading manufacturers of air purifiers in the country, says he is being flooded with inquiries about purifiers throughout the day. “The air situation in the country has deteriorated so much that I have people not only from Delhi, but other parts of the country too, inquiring about what type of purifier to buy,” he says.

The visible pollution as well as the fog has made many people prone to asthma and all­ergies rush to to buy these devices to prevent further damage. In fact, most companies producing such devices are now marketing the air purifiers as the next big revolution since water purifiers. “Air purifiers will be the next water purifiers,” says Jayati Singh.02

 

Concerned about the impact on employees, many organisations are also rushing to install air purifiers in their premises. Several embassies in Delhi have taken measures to set up pollution-free zones within their perimeters. The German embassy, for instance, has equipped its central ventilation system to include an air filter that purifies the air. “Since December 2014, the purchase of air purifiers for the expatriate staff’s private homes has been subsidised and all embassy staff are entitled to an additional three days of leave that must be spent outside Delhi,” says a press release by the German embassy. Most multinational companies too have issued guidelines with incentives to get their employees to install purifiers at homes as well.

So how effective are air purifiers in combating these levels of pollution? One can only guess as so far no government or independent scientific institution has done any study of their impact. Vivek Chattopadhyay of Delhi-based NGO Centre for Science and Environment points out that the air purifiers’ appeal is largely based on faith and says, “The devices perform at best like an air conditioner that traps the air within the room and circulates that same air.”

Chattopadhyay rubbishes the Delhi government’s claims of installing air purifier systems on traffic signals as “useless”, saying the possibility of such devices working in open spaces is even less. And yet, for people living in polluted cities such as Delhi and Patna, the purifiers bring the only believable promise of respite from the deadly pollution, however temporary and limited. No wonder more and more of them are shelling out the bucks, hoping for that sliver of chance to prevent long-term health damage.

The demand for purifiers has increased more particularly due to smaller kids and senior citizens

In the wake of Delhi-NCR region reeling under record breaking pollution levels, the sale of air purifying equipment such as air purifiersand N-95 masks has escalated manifold during last three days in Indirapuram.

The demand of air purifiers is soaring at an all time high in the market and their immediate availability is out of stock. “The demand for air purifiers has increased in the last three days especially in the last two days. We have sold more than 15 pieces today itself and almost a dozen of them have been booked in advance as well,” said Dheeraj, a salesman.

The demand for purifiers has increased more particularly due to smaller kids and senior citizens, who are the worst hit in this air pollution crisis. “I am buying this purifier for sake of my mother who is 60 years old. She has been complaining of respiratory problems for the last two-three days and has been coughing a lot,” said P Verma, customer and resident of Ashiana Upavan, Indirapuram, who was browsing at an electronic store.

“I have two kids, who are 10 and 6 years old. I live on 13th floor and the effect of smog has been bothering my family for long. I had bought this air purifier yesterday itself,” said another customer.

“I was in an urgent need so I thought of coming to a retail store like CROMA, otherwise the sale of these purifiers is also strong online and will cost 10 percent less as well,” said a customer.

A basic air purifier consists of a three layer filteration system; the first filter is the ‘Pre filter’ which cleanses the solid, slightly large impure particles from the environment like hair, larger dust particles, small insects etc., the second filter is called a ‘Carbon filter’ which absorbs the harmful and toxic fumes, cigarette smoke, foul smell among more and the final step of filtration is called ‘Hapa filter’, which cleanses the air of any bacteria and viruses. However, features like digital indicators and sound sensors are basically found in the more expensive purifiers.

At the same time, the demand of face covering masks has also critically increased.

To combat the current level of air pollution, which falls under the P3 level of pollution, special N-95 masks have stormed through the markets which are specially equipped for handling such drastic levels of pollution. “I had bought this N-95 mask today itself, because I have been experiencing breathing issues since yesterday. I tried four different pharmacies but it was out of stock everywhere. I finally got it for Rs 200 from a guy who was selling these for twice the cost,” said a passerby.

Another mask user said, “I have been trying to look for the N-95 masks since yesterday but it was out of stock everywhere, that is why I have bought these simple surgical masks for myself and my children, which are priced at Rs 6 per piece.”

 

 

All you need to know before purchasing an air purifier

What an air purifier?

An air purifier is a simple device consisting of a fan (or two) and filters. Since most pollutants are suspended particulates, these devices work by mechanically separating the pollutants by forcing air through filters. Typically, they don’t consume much electricity either, ranging from 15 to 60 watts depending on the filtration capacity and additional features.

Why do you need one?

There are many different sources of air pollution and if you live in a city, chances are, you need one of these already. Breathing cleaner air helps you sleep better, improves lung function and overall health. If someone in the family suffers from allergies, one of these can be quite useful because it will remove common allergens like pollen, dust, pet hair and so on.

How do you choose one?

Air purifiers are rated with a coverage area (square feet). Measure your room and buy something that has a higher coverage. For instance, if your room is 300sq feet, buy something that is rated for 400sq feet or higher. There are multiple brands to choose from now and the rest depends on your budget and the kind of features you require.

How many do you need?

This depends on where you need clean air. If you’re getting just one, start with the bedroom because that’s where you’ll be sleeping and where you’ll spend the most amount of time.You can move them from room to room as required but it will take a while for it to clean a room completely. Ideally, each room needs to have one of it’s own.

What kind & how many filters do they have?

The primary filter you should look for is HEPA or high-efficiency particulate air filter. It mechanically separates pollutants from the air since it has multiple layers of interlocked fibers. [prisna-wp-translate-show-hide behavior=”show”]The HEPA is the most expensive type of filter. [/prisna-wp-translate-show-hide]There’s also usually a carbon filter which is used to remove odours and dissolved chemicals.Some of the devices include a washable pre-filter -this catches the larger dust particles, hair, pet dander and so on. You can periodically take it out, cleanwash it and ..

Where should you place it?

Placement is important for maximum efficacy. The clean air delivery rate and effective coverage area is measured with the device in an empty room. If you place it under a table, right up against a wall or in between large pieces of furniture, the amount of air it can circulateclean is reduced. Give it enough room and it should work a lot better. Also keep in mind that they work only with closed doors windows.

Any other filter tips?

Filters need to be replaced periodically. This is where the recurring cost of the air purifier lies. Some air purifiers have multiple filters and some have compound filters (two or three in one). If you can, find out the cost of the filters and expected life before making a purchase.
Be sure to switch off the air purifier when sweeping the room -it greatly prolongs the life of the unit. You can also use a vacuum cleaner on the front of a filter to clear off accumulated dust.

Extra features

An ionizer generates negative ions which claims to attract and neutralise harmful particles in the air.Some studies have shown that using ionizers can lead to breathing issues (electromagnetically charged particles can turn into Ozone) so we advise avoiding this feature. Humidifiers use water stored in a tank to boost humidity. Other things you can look for a night mode (extra quiet), WiFi and smartphone control, air quality indicator, display, remote control and temperature humidity sensors. < ..

More about air pollution

Air pollution is not only caused by your car and bursting of crackers. Sources can include seasonal crop burning, construction, burning of fossil fuels in factories, waste landfills and even green house gas emission. Indoor air can also be worse than outdoor air because pollutants accumulate -accelerated by poor ventilation and additional sources of indoor pollution like cooking, pets and chemical cleaning products.

 

Do air purifiers keep out pollution?

At their core, air purifiers are supposed to work like lungs. They work on the principle of sucking in air and passing it through a filter that traps particulates of various sizes. Some air purifiers also use ozone or air sprays to remove odour.

The key claim of air purifiers is that they trap particulate matter less than 10 microns thick. Were such matter to deposit in our lungs they would, over time, erode lung capacity and is equivalent to the damage done by smoking.

Whether air purifiers actually do a good job of making the air around you more breathable rests more on anecdotal evidence than scientific assessment. “You must see the response we get from our customers on how they have reduced asthmatic symptoms after installing our air purifiers,” says Vinayendra Jain, Director, Honeywell Connected Home India.

Business has never been better for Mr. Jain. In only its second year of selling air purifiers in India, sales have doubled, though Mr. Jain didn’t disclose numbers. Given Delhi’s high pollution levels, air purifier demand in the capital far outstrips that in other places, but the company’s products — that can range from Rs.8,000 to Rs.5,00,000 — are evincing interest from as far as Kanpur, Ahmedabad and Tiruchi.

“Outdoor air and indoor air are different subjects,” says Rakesh Kumar, director, CSIR-National Environmental Engineering Research Institute, “If the air outside has become twice as worse, it doesn’t mean air inside (a residence) has worsened as much.” Dr. Kumar says air purifier equipment in India hasn’t been calibrated to Indian air standards because the government hasn’t specified how it must be done so.

Air outside and inside the house

That’s why manufacturers can make claims on the efficacy of their purifiers without subjecting them to an investigation by local authorities. Indoor air has a different composition from outside. Air quality inside the house is determined by volatile organic compounds (from paints), bio-aerosols, nitrous oxides (from cooking gas), unlike air quality outside that is measured on the basis of particulate matter, carbon monoxide, ozone and sulphur dioxide levels. “The paradox is that indoor air quality doesn’t have standards for PM2.5 or PM10,” says Arun Sharma, professor, Community Medicine, University College of Medical Sciences, Delhi, “and India has no standards for indoor air quality.” That’s because there’s no agreed definition anywhere of what is an acceptable level of dust and other compounds within a home.

Dr. Kumar notes that well-ventilated homes are the best defence against pollution. “The background concentration of dust, especially in Delhi, is high and there is a natural acclimatisation by our bodies. Air purification systems are most effective in closed spaces… offices, shopping malls with poor ventilation,” he says. Dr. Sharma says that air purifiers do reduce particulate matter over a limited area, but whether they improved people’s health over the long term remains an open question.

Air purifier sales spike in India as its cities battle pollution

As the government fumbles over effective measures to curb severe air quality in India’s capital of New Delhi, people are increasingly looking at air purifiers for relief.

Major ecommerce businesses in India are reporting significant surge in the sales of air purifier units in the country. The product category, which has existed in India for over two decades but struggled to become a household name, has suddenly become a talking point among people on social media.

Amazon India says it sold three times more air purifiers this Diwali compared to the previous month. Almost half of all these orders came from cities such as Delhi, Gurgaon and Bangalore. Flipkart had similar findings, noting that it has seen 2.5 times growth in air purifier units sale compared to last year.

The sudden interest in air purifying products among people comes as several Indian cities report of increasingly growing air pollution after Diwali. The festival of light, which sees many people burst crackers, combined with the burning of farmlands and residual fodders in nearby states, have resulted in an unprecedented severe air quality in New Delhi and several other states in India.

Five days after Diwali, for instance, the air quality index reading of the national capital is still classified as “hazardous”. A report on UNICEF published this week found that over two billion children worldwide breathe polluted air. India and China were among the most affected countries.

Not just air purifiers, but people are also actively looking for air masks for immediate comfort. “Sales of pollution masks have jumped 6X in the last few days with customer demand being 13X over last year. The highest number of orders for pollution masks were placed by customers on Nov. 1. The demand continues to be high from northern India with most orders coming from Delhi,” an Amazon India spokesperson told Mashable India. The surge in sales happened a couple of days after Diwali, which fell on Oct. 30 this year.

While The Government Is Taking Its Own Time, These People Are Fighting For Clean Air

The conversation around air pollution is not a new one for India with several attempts being made in the past – some successful and some not as much – to educate citizen on the need to combat air pollution through the year.

Unfortunately, despite an all round effort to clean up the air, the results are bleak. With Delhi topping the chart in the country with the most polluted air. There have been some individuals who have worked against the odds to fight to the right to better air quality in the country.

Namita Gupta has been surviving on antibiotics because of pollution. What bothered her even more was the discomfort her daughter, who is an asthma patient, faced. She thought of shifting to the US when the idea of making an app that could monitor pollution struck her. She decided against the plan and created an App from scratch. Her App, Airveda, helps monitor air pollution levels and is quite simple to operate.

Saurabh Bhasin

Shocked by the impact of air pollution on him as well as his family, Saurabh Bhasin and his wife have launched a legal battle with the Delhi government for cleaning the city’s air. Among the plaintiffs is his 15-month-old daughter and two other other toddlers. The case has been filed in the Supreme Court stating that the poisonous air deprives them of their “right to life” as guaranteed by the Constitution.

“I don’t expect things to improve overnight, but I do want to see government bodies take cognisance of how drastic it is, and take some serious measures to make it better,” Bhasin told the media.

Swechha Foundation

Air Warrior

The Swechha Foundation has been promoting plantation drives across Delhi and promoting better eco-health in sensitive zones like the Yamuna among many others. During the monsoon months each year, the foundation conducts a “Monsoon Wooding” programme and with a target of planting 2,000 new trees each year, the foundation has already planted more than 10,000 trees in and around the capital.

Graviky labs

Air Warrior

The Bengaluru-based lab has been capturing soot from vehicular emissions and use it to extensively to remove heavy metals and carcinogens, before distilling it into this dense black ink. Soot, produced due to the incomplete burning of fossil fuels, easily enters the body’s bloodstream when inhaled at traffic signals, wreaking havoc.

“Air-Ink is formulated by industry standards. We can put it to a range of uses—regular inks, screen painting, newspaper ink, oil-based paints, alcohol-based paints, spray cans, even calligraphy ink,” says Nikhil Kaushik, one of the founders of the company.

Clean Air India Movement (CLAIM)

Air Warrior

CLAIM

Clean Air India Movement (CLAIM) is a nationwide launched campaign launched in May 2015. The campaign is speared by an air purifier company . The Clean Air India Movement is a 360° degree campaign aimed at engaging, encouraging, and educating Indian citizens to adopt air friendly measures in the interest of the country and its children. “Our campaign aim is to tell people that we are not helpless individuals when it comes to challenging air pollution. Even simple acts by individuals or sole companies such as it can make a difference when it comes to showing responsibility and care, which is why we have taken the initiative to make the call and mobilisation for action,” said Kannan .
