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.

Alkaline Water do you know?

Despite a well regulated municipal water supply and near nationwide access to safe drinking water, Americans spend over $12 billion each year on bottled water. We are greeted with an ever expanding selection of waters for sale—pure water, water with electrolytes, flavored water, water from a spring, water from a glacier, water from a drought ridden state. But few varieties of water make as bold-faced claims of improving health as alkaline water. Available bottled or by do-it-yourself purifier, alkaline water is touted as anything from a fountain of youth to a panacea.

What is “Alkaline Water”?

First, a brief review course in high school chemistry. The pH, or potential hydrogen, scale runs from zero to fourteen, with 7 as the neutral middle. An acid is a substance with a pH of less than 7. A basic or alkaline substance has a pH of greater than 7. The World Health Organization has no health based guideline for pH in our drinking water. There is no definitive evidence that identifies an optimal pH—in the US, water from the tap or bottle ranges anywhere from 5.2 to 9.5 depending on the state or brand of water.

When companies talk about selling you alkaline water, though, they are not just talking about the pH. They are referring to alkalinity—a substance’s ability to buffer acid, preventing rapid changes in pH. Regardless of its pH, for water to have alkalinity requires the presence of mineral compounds—you cannot magically change the alkalinity of pure H2O without adding something to it (magnesium, calcium, bicarbonate, etc.). Among other things, this means that any company selling water that is both “pure” and “alkaline” is misleading its consumers.

There are two warring camps in the alkaline water world—those who support at home water ionizers (“artificial”) and those who swear by bottled natural alkalinized water. Artificial alkaline water is generally tap water run through an electrical machine. The ionization process splits water molecules and raises the water’s pH. Companies that make naturally alkaline water claim that artificial alkaline water is dangerous. While some studies in rats have shown damaging side effects with consumption of ionized water, there is no such research in humans.

In comparison, one hundred percent natural alkaline water is born when water picks up minerals (calcium, magnesium, and others) as it passes through rocks in nature, organically changing its pH and alkalinity. Purveyors claim that only this natural water can offer benefits like reducing the risk of Alzheimer’s and slowing the aging process.

Does Alkaline Water Improve One’s Health?

That depends on who you ask. If it is someone who has read scientific literature, the answer will be that there is no evidence indicating benefit or harm from drinking alkaline water. If it is someone trying to sell you an expensive ionizer or alkaline bottled water, the answer is yes, absolutely.

In theory, alkaline water serves to balance out a condition called acidosis. In a healthy individual, the lungs and kidneys work to maintain a normal body pH. Problems with these organs can lead to either metabolic or respiratory acidosis (or alkalosis). Human blood has a pH of approximately 7.4—slightly alkaline. A fluctuation of as little as .05 in blood pH can have serious health consequences (including death), but the pH of the rest of the body can vary widely. In the stomach, for example, where acids help us to digest food, the pH can go as low as 1.5. Alkaline substances can, in essence, cancel out acidity. That’s the idea behind antacids like TUMS. Treatment for acidosis depends on what’s causing the pH imbalance.

Water companies suggest that alkaline water will help to maintain your pH, correct side effects from acidosis, increase your energy, improve your thinking, possibly even reverse aging. The idea that human beings must drink alkaline water for health is partly rooted in the idea that Americans on a high fat modern diet (so, most of them) are in a constant state of acidosis.

It is unclear where, exactly, these companies think this alkaline water is affecting us. The stomach is highly acidic and those with excessive stomach acid may benefit from the alkaline properties. But drinking water is not going to flush all of the acid out of your stomach—nor would you want it to (it’s important for things like digestion). Further, and here’s the real kicker, most of the water reabsorption happens in the intestine where your digestive tract secretes enzymes to neutralize stomach contents. So the pH and alkalinity of the water you consume is likely more or less irrelevant. By the time water gets around to affecting your blood, it has already had its pH altered several times by your digestive tract.

So the pH and alkalinity of the water you consume is likely more or less irrelevant.

Dr. Richard Waldhorn, a clinical professor of medicine at Georgetown University, explains:

Despite claims by its proponents that alkaline water will boost metabolism, slow aging, prevent cancer and improve physical appearance for starters, research evidence of support is underwhelming. I had a professor in medical school who used to say that ‘the dumbest nephron (functional unit of the kidney) is smarter than the smartest intern.’ I would rely on the kidney and respiratory system to take care of acid-base balance.

In general, if a natural remedy seems too good to be true, it usually is. The spectacular benefits of alkaline water—detoxification, improved mental clarity, hair growth, Alzheimer’s prevention, just to name a few—are not scientifically backed. Purveyors of “natural alkaline water” can preach the hazards of “artificial alkaline water,” but the truth is there is no evidence that their product does any good either. The healthy human body evolved for the careful regulation of our blood pH, no fancy water needed. If you are concerned that your health is being affected by a pH imbalance, please consult a physician rather than relying on magical water cure-alls.

That said, we can not discount the placebo effect. Some people may feel healthier drinking tap water after it has been processed through a $4000 machine. Others may swear that drinking alkaline water bottled from Hawaiian springs makes them feel 20 years younger. Still others will be perfectly content filling their reusable water bottles straight from the tap. Regardless of the type of water you consume, the most important thing is that you drink it.

About hydrogen water generator

Sydney, Nov 29 (IANS) Australian researchers have reported the use of a new ultra-thin catalyst to split water into its two components, oxygen and hydrogen, to be converted and used as fuel, a report said on Tuesday.

The researchers at the Griffith University used the sheet-like, highly efficient catalysts that has long-term stability and help spur the process to create economically viable clean fuel.

The latest research was published in the Nature Energy journal, Xinhua news reported.

Just as sunlight generates electricity, the water-splitting process could do the same via the generation of clean chemical fuel such as hydrogen, a report quoted Professor Huijin Zhao, the director of Griffith’s Centre.

Hydrogen would be a promising clean fuel over petrol in the foreseeable future, Zhao said.

“Scientifically it’s already demonstrated, it’s already working but to do this in a way that’s economically viable, there’s still a bit of work to do and we need government policy, general public support,” he said.

“You also need those big companies to realise they should not dig up out of the ground anymore,” he said.

“It’s not just a simple technology issue.”

Team cracks mystery of London’s ‘killer fog’

In 1952, a killer fog containing pollutants covered London for five days, causing breathing problems and killing thousands of residents. The exact cause and nature of the fog has remained mostly unknown for decades, but scientists now believe the mystery has been solved.

The same air chemistry also happens in China and other locales, they report.

In December of 1952, the fog enveloped all of London and residents at first gave it little notice because it appeared to be no different from the familiar natural fogs that have swept over Great Britain for thousands of years.

But over the next few days, conditions deteriorated, and the sky became dark. Visibility was reduced to only three feet in many parts of the city, all transportation shut down, and tens of thousands of people had trouble breathing. By the time the fog lifted on December 9, at least 4,000 people had died and more than 150,000 had been hospitalized. Thousands of animals in the area also died.

Recent British studies now say that the death count was likely far higher—more than 12,000 people of all ages died from the killer fog. It has long been known that many of those deaths were likely caused by emissions from coal burning, but the exact chemical processes that led to the deadly mix of fog and pollution have not been fully understood over the past 60 years.

The 1952 killer fog led to the passage of the Clean Air Act in 1956 by the British Parliament and is still considered the worst air pollution event in the European history.

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 seagull flies through smog above the skyline of the City of London on April 2, 2014.

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.

 

SO,you should buy a air purifier in your school/home/office to improve air quanlity.

AS for this situation.I’ll introduce our company Olansi air purifier products.

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.

air purifiers are supposed to work like lungs

In the absence of any government-set standards for indoor air quality, their efficacy rests more on anecdotal evidence than scientific assessment.

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.
