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.

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

delhi, delhi pollution, delhi air pollution, air pollution delhi, delhi pollution, delhi pollution control, delhi air pollution control, delhi news, india news"

(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?

 

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.

Outdoor air purifier project gathers dust

An outdoor air purifier was installed outside Palika Bazaar in 2010.photo: special arrangement

While the Delhi government is considering installing outdoor air purifiers at traffic intersections, it turns out that the last time the city experimented with such a project, it was left hanging for five years.

The New Delhi Municipal Council had set up an air filtering station in 2010, before the Commonwealth Games.

The purifier was installed outside Palika Bazaar in Connaught Place free of cost by a company called System Life on March 6, 2010. The machine cleaned 10,000 cubic metres of air every hour for about 18 months. The system worked by cleaning polluted air of particulate matter and gases with fabric filters, active carbon cartridges and electrostatic filters.

According to System Life India director Dhruv Chanana, the machine was operational till October 18, 2011, before being removed. “It was removed because no one wanted to accept the need to clean the air,” said Mr. Chanana, adding that had the NDMC gone ahead with more such purifiers, the pollution levels in the area would have reduced. That being said, the authorities have remained mum on the effectiveness of such a project.

Dr. P.K. Sharma, NDMC’s Medical Officer of Health, said it was a pilot project and had not received the necessary approvals to continue. “It was a free demonstration by the company. Before continuing with the project, it required clearance of the Central Pollution Control Board and the Delhi Pollution Control Committee. We are yet to receive that,” said Dr. Sharma.

95% efficiency

The air samples from the trial were analysed by three Italian scientists, including from the University of Modena. Their report was submitted to the NDMC and subsequently to the DPCC.

According to the report, a copy of which is with The Hindu , a total of 2.12 kg of particulate matter had been detained in 860 hours and the filtering efficiency of the system was 95 per cent.

The report concluded that with an “appropriate number of systems” (about 22 for Connaught Place) the air quality of an area could improve.

The DPCC, which works under the Delhi government’s Environment and Forest Department, for its part, did not make any comments on the efficiency of the system, as per a letter sent by one of its scientists to System Life on October 12, 2010. According to the letter, a copy of which is with The Hindu , the DPCC had not commented on the report “as no specific study was undertaken” by it.

Environmentalists, however, used the experience of the NDMC project to question the AAP government’s proposal to install outdoor air purifiers. Anumita Roychowdhury, the head of the Centre for Science and Environment’s air pollution and clean transportation programme, said air purifiers worked within confined environments, “but outdoor air is a complex chemistry with dynamic movement pattern”.

How to choose an air purifier: 6 tips to help you find the best one

Diwali marks the beginning of winter smog in north India and the air remains thick with pollution till April. If your lungs are protesting and you are at your wits end over what to look for in an air-purifier to clean indoor air, look no further.

Barun Aggarwal, CEO of BreatheEasy, provider of indoor air purifying solutions, gives a checklist of things to look for in an air-purifier for your home or workplace.

HEPA filter is a must

Check the specification of the air purifier to see whether it has a HEPA (high efficiency particulate air) filter. “There are many products in the market which say HEPA-like filters, people must avoid these. The HEPA filter clears out the small particulate matter (PM2.5 and less) that can go deep within the lungs and cause respiratory problems,” said Aggarwal.

Heavy activated charcoal

While buying an air purifier ensure that it has activated charcoal in it to remove harmful gasses as well as bad odours.

Check for a pre-filter

Buy air purifiers that have a pre-filter to remove the larger particulate matter. “In an air purifier that doesn’t have a pre -filter, even the large particulate matter present in the air would reach the HEPA filter and reduce its efficiency,” Aggarwal said.

 

Pre-filter can be easily cleaned or replaced, prolonging the life-span of the purifier.

High Clean Air Delivery Rate

The higher the Clean Air Delivery Rate (CADR ) , the more air gets purified. The number describes the purifier’s ability to remove all pollutants from specific amount of air.

Area to be purified

Usually manufacturers list the area the air purifier works best in square feet. “While buying a purifier, you have to halve the area and see whether it suits your need. This is because manufacturers test equipment in a sealed environment with the purifier running at high speed. These conditions are not possible in real life because running a purifier at full speed is noisy and home and offices have leaky windows and doors opening, which brings doown efficiency,” said Aggarwal.

Avoid purifiers with negative ions, photocatalytic oxidation, UV lights

Avoid air purifiers that have either of the three specifications as these can potentially release ozone as a by-product. “Ozone is harmful for the lungs and is known to lead to more incidents of asthma attacks and other respiratory problems,” Aggarwal said.
