Debate over whether should schools use air purifiers

Debate over whether should schools use air purifiers

With the repeat occurrence of smog in China, many parents call for installation of air purifiers in classrooms. Some parents even offered to pay for the purifiers. However it is refused by school authorities. It has caused hot debate over whether air purifiers should enter schools.

Experts say air purifiers on the market are mostly designed for homes or offices. It still needs evaluation to know if it is useful in classrooms. Education authorities in Shanghai said they will coordinate with relating departments and work for a feasible plan.

Meanwhile, reports said a test has been held in a school in Beijing. After using the air purifier, the level of PM 2.5 in the classroom decreased, but with dozens of students in the enclosed room, the dense of CO2 has passed the healthy standards.

Is using an air purifier critical?

In an age where a sedentary lifestyle plays its role to cut years off the average life expectancy rate, basic necessities like clean drinking water and now fresh air are becoming a challenge to obtain too. I remember as a child, my father waking me up early in the morning to get a whiff of fresh air. Mornings in my small town in Uttar Pradesh, used to be quiescent, serene with air that was fresh, pure, impregnated with a subtle scent and sound of bells coming from a temple located at a distance.

 

Delhi grappled with ‘severe’ air pollution this year with levels going through the roof post Diwali. Most areas in the city recorded a whopping 900+ on the pollution meter – 10 times more than the normal range. With winter setting in, the pollutants tend to blend with the dense fog and further worsen the condition.

Is using an air purifier critical?

The answer would largely be affirmative. Bhaskar Deol, India representative, NRDC (Natural Resources Defense Council) opined, “I work with the environment sector. Recently, I ran the half marathon wearing a mask and after finishing it, which was a couple of hours later, I found the white fabric had turned black. Air pollution is one of the leading causes of deaths in India. Not many would believe this, but it is true. I have felt my cough getting worse over these days and it was then that I decided to get an air purifier for myself.”

According to Mr. Barun Aggarwal, CEO BreathEasy, “You should have the right purifier at the right place. That is the challenge. In my opinion, it is no more a luxury, it has become a necessity. To make it cheaper and accessible to people from all walks of life, is a challenge that we have set out to overcome.”

This piece sets out to understand the mechanism of a typical air purifier.

 

What is an air purifier?

As the name suggests, an air purifier is a device which removes contaminants and pollutants from the air. It works like any filter, by sucking in the air, passing it through cleaning mechanisms and giving out clean air. Unlike water, which is chemically treated, air is not purified chemically but filtered. The filters can be made of a range of materials but the technology differs from one purifier to another.

4 Basic things to keep in mind

In my opinion, the preliminary step for anybody who aims to buy an air purifier would be to self-educate. It is not like water filters or air-conditioners where you won’t have to think much before investing. Think about your needs, educating and reading up on pollution and doing your own research before heading out to buy one is imperative,noted Bhaskar.I feel that air purifiers are fairly simple machines to understand. There has not been much publicity and education about them, that’s why an average consumer feels baffled when thinking to buy one. All you need to factor in while making a choice would be (a) the place where you want it to be fixed and hence the size of the machine (b) your budget (c) how economical the machine would be in the longer run (need to change the filters, size of the filter) and of course the technology – your machine need not have anything fancy and superfluous features but three basic things – a basic pre-filter, an activated carbon layer and a HEPA filter,” shared Mr. Barun Aggarwal.

 

Make Olansi choices 

Access your needs and see how big the room is which needs purification. Central purification will need bigger machines or purifiers to be fitted as a part of the central cooling, heating and ventilating system (HVAC). “I bought a slightly bigger model for myself than my room would require because I wanted it to work efficiently even at low speed. Also, I was also mindful of the fact that I may be moving in the near future, in which case I might have a larger room to myself and would require a bigger machine later,” shared Mr. Depp. You don’t really invest in such appliances again and again, it is like a one-time investment for years, so you ought to factor in your present needs as well as your ever expanding, prospective requirements.

Air pollution causes 467,000 premature deaths a year in Europe so you need air purifier

Air pollution is causing around 467,000 premature deaths in Europe every year, the European Environment Agency (EEA) has warned.

People in urban areas are especially at risk, with around 85% exposed to fine particulate matter (PM2.5) at levels deemed harmful by the World Health Organization (WHO).

These particles are too small to see or smell, but have a devastating impact.

PM2.5 can cause or aggravate heart disease, asthma and lung cancer.

How big is the problem?

It’s pretty bad. Within the European Union (EU), more than 430,000 people died prematurely due to PM2.5 in 2013, the most recent year with figures available.

According to the EEA’s Air quality in Europe – 2016 report, the toxic gas nitrogen dioxide (NO2) – released by vehicles and central heating boilers – has an impact equivalent to 71,000 premature deaths a year.

Ground-level ozone (O3) is also killing people – an estimated 17,000 annually in the EU.

Unlike the protective ozone layer in the stratosphere, ground-level ozone is harmful, formed when emissions like NO2 react with other pollutants and “cook” in heat or sunlight.

A chart showing the ten European countries with the worst levels of PM2.5

The European countries with the worst levels of PM2.5 are Bulgaria, Poland and the Czech Republic.

Nations like Poland where coal is a major source of electricity production tend to rank at the bottom of air quality measures, according to the EEA.

 

In 2013, Bulgaria provided four of the five worst European cities for high particulate matter. Costs to ill-health from coal power plants in the country are estimated to be up to €4.6bn ($4.8bn; £3.9bn) per year.

In the UK, air pollution overall costs the economy more than £20bn per year – just under 16% of the NHS’s annual £116bn budget.

Air pollution deaths mapTechnically, European air quality actually improved between 2000 and 2014. Levels of PM10 – another tiny pollutant particle – fell in 75% of the EEA’s monitored locations.

PM2.5 concentrations also dropped on average between 2006 and 2014.

But EEA executive director Hans Bruyninckx says “unacceptable damage to human health and the environment” is still rife.

Outdoor air pollution contributes to about 40,000 early deaths a year in the UK, according to the Royal Colleges of Physicians and of Paediatrics and Child Health.

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.

 

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.”

 

 

Can air purifiers and masks protect you from the poisonous Delhi air?

With worsening smog levels turning Delhi (NCR) into a virtual gas chamber, demand for air purifiers and masks is at an all-time high. Delhi experienced the worst smog in 17 years after Diwali, with PM2.5 readings, which have a safe limit of 60 micrograms per cubic meter, having gone up to an alarming 900 in some parts of the city last week. The situation triggered a spurt in the purchase of air purifiers and masks in the national capital.

airpollution“I bought an air purifier and masks primarily because of my children. My son and daughter were complaining about discomfort in breathing after Diwali night,” says Prasanna Singh, a resident of Alakhnanda in South Delhi. However, he’s clueless about the effectiveness of the masks and air purifier. He adds,

I don’t know whether they actually help in filtering out particulate matter and hazardous gases or not.

Prasanna isn’t the only one expressing concern over the quality of masks and purifiers; YourStory spoke to several people who purchased them – all seemingly unaware of the true effectiveness of the products.

When it comes to air purifiers, one tends to look at the lower and mid-range products in the market and get excited by the area covered and the lower prices (in the range of Rs 10,000-20,000). One must read the fine print – these devices have inferior motors and far inferior filters.

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?

In carrying out the inspection work at the same time, in order to guide consumers to purchase, quality inspection departments also carried out detection and comparison of product key performance index, were all random products of particle clean air volume (CADR), formaldehyde (CADR), the amount of clean air purification efficiency of particulate matter (performance), formaldehyde purification efficiency (performance), particulate matter (CCM), the cumulative amount of purified six key performance indicators such as noise detection and single detection value together with the inspection results be announced to the public, and guide consumers to carry out scientific and rational choice of products.

Experts suggest that if consumers choose to air purifier products, priority selection to determine the qualified product. “Since the implementation of the new GB products, on one hand, it is through the quality, on the other hand also shows that the nominal value of sound, not deceive consumers suspected”

Experts suggest that the haze of consumers are concerned about the selection of particulate matter purification capacity is relatively good purifier. You need to see the removal of formaldehyde CADR indicators relatively large purifier.

 

 

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”.
