Beijing to get largest air purifier

To the bafflement of some local residents, the world’s largest outdoor air purifier arrived in Beijing to help the capital combat its persistent hazardous smog.

The brainchild of Dutch designer Daan Roosegaarde, the tower is  undergoing last -minute checks in Beijing’s 751 D Park art area. The public, meanwhile, are bemused by the tower’s function and have called on authorities to curb dangerous sources of polluting particles.

The Smog Free Tower will soon be opened to the public, and will be toured across the country, the Legal Daily reported, quoting China Forum of Environmental Journalists, an NGO under China’s Ministry of Environmental Protection.

According to the Studio Roosegaarde website, the 7-meter-tall tower can capture about 75 percent of PM 2.5 and PM 10 particles in its vicinity and then release purified air to create a “bubble” of fresh air around it. The tower can clean 30,000 cubic meters of air per hour through its patented ozone-free ion technology.

Liu Guozheng, CFEJ secretary-general, told the newspaper that bringing the tower to Beijing is intended to warn  authorities never to forget their duty and encourage the public to pull together to combat the smog.

Beijing has been plagued with heavy smog since the beginning of October. The city’s environmental authorities issued a yellow alert for air pollution Tuesday afternoon.

Netizens expressed their frustration over the tower. “The so-called divine smog cleaner is more like a piece of performance art, which makes almost zero difference to cleaner air in the city. It devours the polluted air and exhales fresh air, but so little it won’t make any difference. The air will stay polluted,” said one Sina Weibo user.

The Science of Air Purifiers and Health: Is There Data?

8840f5c124c97c51bed8474bb443115d

What is one of the hottest gifts in China? Perhaps you could give “the gift that keeps on giving”: an indoor air purifier. They certainly are all the rage in China since last year, with skyrocketing sales and sold-out inventories after the trio of highly publicized airpocalyptic crises. I think this is a good turn of events: plenty of independent testing,including mine, has documented that a good air purifier can dramatically improve your indoor PM2.5 by 80% or more. But is there any good data that proves that this actually makes you healthier? It seems logical, of course, that decreasing exposure to pollution would decrease harmful health effects. But medical history is filled with tales of common sense and tradition that later turn out to be worthless or harmful — like bloodletting, or the more modern tradition of multivitamins. A big percentage of people reading this article take a daily multivitamin, assuming it’s “healthier” to do so, but the best evidence shows they are worthless, and possibly harmful. Could air purifiers be the same?

In theory and in testing, a good purifier should improve a room’s pollution levels more than 80%; this80% reduction is also what the private Association of Home Appliance Manufacturers (AHAM) uses in their clean air delivery rate (CADR) tests, which are widely cited in comparison charts of air purifiers. So let’s say you’ve installed a top-of-the-line purifier in your living room, feeling quite safe and cozy. But how much of your time is actually in that filtered room? Or maybe the purifier is too small for that room size, or the filters are old, or the fan speed is too low, or the windows are open? Even this commonly cited CADR test is just a lab test for only 20 minutes — what about in the real world? I want to take this conversation to the next level, seeking out proof that your health will improve when using these machines. I want to be able to tell my patients and readers that there are published research studies which followed people over many months or even years, compared them to a control group not using air purifiers, and measured their health to see if there was any improvement in heart and lung disease, cancers and death rates. Are there any such studies?258035c025c59745eaab068434d9d6c6

searched the Pubmed scientific database to find the best studies, and I was disappointed but not surprised to find very little strong data. A properly designed research project like this would be very difficult and expensive. But there are a few attempts, especially studies looking at using HEPA filters to help children with asthma. One was a systematic review published in 2002, which found that air filters helped to improve asthma symptoms — but the effect was small, and there was wide variation between studies which made conclusive assessments difficult. A more recent, very well designed study published in Pediatrics in 2011 followed two hundred children with asthma who also were exposed to secondhand smoke at home, and gave half of the kids a true HEPA purifier and the other half a fake purifier for their bedrooms. After a year, the HEPA group of children had less doctor visits for asthma flares, which possibly — but not conclusively — could be due to the 25% decrease in PM2.5 in their homes.

Other studies have focused on allergies, including an interesting study from 2008 which assessed children with documented pet allergies, following them over a year and recording lung function and blood markers. After a year, those who used HEPA air purifiers showed no clear difference in lung function, use of allergy medicines, or blood markers of allergies. Another study back in 1990 was a bit more impressive, showing not only a 70% reduction in indoor PM0.3 but also improved patient symptoms of allergies.

All of these hint at health benefits, but they still dance around the edges of what I want to know for us in China and the developing world. In the USA, most of the air purifier marketing and testing focuses on allergies and asthma. But here in the developing countries, the air pollution is much more severe and thus the health risks are far more serious. We are worried about pollution’s long-term risks of death, heart and lung disease and cancer. These studies I just mentioned still aren’t answering that deeper question: can long-term use of indoor air purifiers prevent death, heart and lung disease, and cancer?

The best study I found was published in January 2013 in Indoor Air. It was very well designed for this complicated type of study, being a randomized double-blind crossover study of 20 homes over three weeks, using an air purifier or a placebo purifier. Their main goal in this remote First Nations community in Canada was to assess whether air purifiers could improve cardiorespiratory health. As their abstract says,

“…each home received an electrostatic air filter and a placebo filter for 1 week in random order, and lung function, blood pressure, and endothelial function measures were collected at the beginning and end of each week… On average, air filter use was associated with a 217-ml increase in forced expiratory volume in 1 second, a 7.9-mm Hg decrease in systolic blood pressure, and a 4.5-mm Hg decrease in diastolic blood pressure. Consistent inverse associations were also observed between indoor PM2.5 and lung function. In general, our findings suggest that reducing indoor PM2.5 may contribute to improved lung function in First Nations communities.”

This same Canadian research team had earlierpublished a similar study, testing 45 non-smokers for 7 days in 20 homes that used wood stoves, comparing health effects with or without HEPA purifiers. The people using the filters showed improved endothelial function and biomarkers of inflammation such as CRP. As most pollution researchers now see pollution as a pro-inflammatory disease, testing for such biomarkers could indeed be an accurate surrogate for later health problems. This approach is also being used in studies of air pollution masks, which I recently reviewed.

My take from these studies? Firstly, they all confirm what we already know: air purifiers can reduce the levels of indoor PM2.5, but with a wide range of effectiveness. Secondly are the more important results looking at health markers. I think the most encouraging finding was the First Nation study showing improvement in lung function, even in such a short amount of time (less than a month). Their data was a bit less convincing on blood pressure improvements, but perhaps a larger study would help confirm their initial findings of a slight improvement.

None of these studies are slam-dunk proof for me, but I honestly don’t know whether we ever will get many more well designed studies like these, unless governmental researchers or Gates-type philanthropists fund them. But until better studies come along, we must rely on what we do know:

  • Air pollution contains many chemicals, but PM2.5 is considered to be the most harmful to health.
  • There is no such thing as a “safe” level of PM2.5. Lower is always better.
  • Worsening PM2.5 causes deaths from all causes, especially heart and lung diseases and cancers. Many studies have shown this, including this 2013 meta-analysis of the population in China.
  • On the brighter side, long-term improvements in PM2.5 do help to decrease mortality. The best study was a huge epidemiological analysis of entire populations in American cities as the air improved from the 1970’s to 1990’s. Lifespans improved for everyone, for a multitude of reasons, and they estimate that 15% of the improved life expectancy was due to cleaner air.
  • Shorter studies have also shown improvements in health from better outdoor air pollution. The best designed study I’ve seen on this happened right here in Beijing, during the 2008 Olympics. A team of researchers followed 125 healthy young doctors before, during and after the Olympics, and found improved blood pressure, heart rate and other biomarkers of inflammation during those lovely days of improved air pollution. Another encouraging studyfollowed pregnant women and their babies in Tongliang, China both before and after a heavily polluting coal-fired power plant was forced to shut down in 2004, and found improved neurodevelopmental scores in newborns at age 2 years.

Is all of this enough to convince you to use an indoor purifier? For me, I was already convinced years ago — it’s not just common sense, it actually makes biochemical sense and also perfectly fits withthe precautionary principle: “When an activity raises threats of harm to the environment or human health, precautionary measures should be taken even if some cause and effect relationships are not fully established scientifically.”

Fighting Childhood Asthma with an Air Purifier

Early detection is the first step in fighting childhood asthma

Does your child experience shortness of breath or irregular breathing? Do you notice a whistling sound when he or she exhales? Does your child have a persistent cough? If so, there is a good chance he or she may be developing asthma, one of the most serious chronic diseases in children and adolescents, affecting nearly nine million children under the age of 18.

According to the American Academy of Allergy, Asthma & Immunology (AAAAI), 50-80% of asthmatics develop symptoms before the age of five. This is why early detection and working with your child’s asthma specialist is important. Untreated asthma can lead to permanent damage to the airways making it difficult to bring the condition under control.

“Children whose immune systems are not fully developed are most at risk for developing asthma,” said Christopher C. Randolph, MD, FAAAI, and Vice-Chair of the AAAAI’s Asthma Diagnosis and Treatment Interest Section. “However, with early detection, the disease is easier to bring under control, improving the quality of life for your child.”

Look, Listen & Learn

There are no clear markers to predict who will develop asthma and who won’t. However, there are clues and symptoms you can look and listen for in your child that may indicate asthma. Ask yourself these questions:

  • Does your child have allergies? The relationship between asthma and allergies is very strong. If your child has allergies, be on the look out for potential signs of childhood asthma.
  • Does your child cough or clear his/her throat often, even when they aren’t sick? This could be constant or just intermittent. Not all children who have the disease exhibit symptoms each and every day.
  • Does he/she wheeze or is there a whistling sound when your child exhales or with upper respiratory infections?
  • Do you notice shortness of breath, rapid or irregular breathing in your child?
  • Does your child complain of chest tightness? A young child may say his/her chest “hurts” or “feels funny.”
  • Does your child seem fatigued? A child might slow down, stop playing or become easily irritated.
  • Does your child have problems sleeping because of nighttime coughing or difficulty breathing?
  • Is there a family history of asthma and/or allergies?

If you answered “yes” to any of these questions and you suspect that your child has asthma, schedule an appointment with an asthma specialist, such as an allergist/immunologist, a physician specially trained to manage and treat asthma and allergies. An allergist/immunologist will work closely with you to create a daily management plan for your child, demonstrate proper medication use, and develop an asthma action plan, which outlines the actions to take if your child’s condition worsens.

Learn

While there is no cure for asthma, complete control of the disease can be obtained with appropriate management and treatment. Learning your child’s asthma triggers and what steps to take to decrease symptoms is an important step to keep your child’s asthma under control. Children whose asthma is properly controlled should be able to participate in regular activities such as attending school every day and playing sports.

 

How an Air Purifier Relieves Your Allergies

How an Air Purifier Relieves Your Allergies

Have you ever considered an air purifier for your allergies? Does your head feel like it’s in a vice grip, are your eyes are watering, is your nose running and your throat itching? Are you desperate to feel like yourself again? It may be time to consider an air purifier.

 

Why use an air purifier for allergies?

Using an air purifier offers long-term relief, one that can also lower the cost of managing your allergies. According to the Center for Disease Control and Prevention, 13.1 million doctor visits a year are due to allergies. Common triggers for allergies are dust, molds, pets, and seasonal triggers like pollen.

An allergy is simply your body’s overreaction to a foreign substance. An air purifier can greatly reduce the amount of allergens inside your home by tackling the problem at the source.

 

Italian man’s portable air purifier bedazzles onlookers

Deal with it. That’s the typical mentality most of the Chinese people have every time the air pollution gets worse.

But this Italian young man was apparently not happy about the status quo.

On Wednesday, he was spotted carrying a self-made air purifier, while riding on a bike in Chengdu, Sichuan Province.

According to the man, who called himself Mike, it cost him about 1,500 yuan($245) to build the device, using a home air purifier and attaching an oxygen mask to it.

Moreover, he also installed a storage battery and inverter as power supply.

According to experts, it’s possible to convert room air cleaners into portable air purifiers.

However, even if it’s technically possible to do so, experts say it is quite unlikely to achieve the same effectiveness in air filtering as a good breathing mask can do.

And even in developed countries, where the air quality is much better, an air cleaner needs to exchange the air in a room seven to eight times every hour, in order to maintain desired indoor air quality.

What to Look for When Shopping for an Air Purifier

A lot of people worry about the air they breathe. With all of the cars on the road and factories spewing out toxins, air pollution is pretty bad. What a lot of people don’t realize is that indoor air pollution can be even worse than the pollution outside.

Indoors we have to deal with things like dust, pet dander, mold spores, pollen, volatile organic compounds, fumes from cleaning products and other household chemicals, the list goes on and on. Some of the things floating around in the air inside your home can trigger allergic reactions, and some things can actually make you very sick.

Because indoor air pollution is such a big problem, buying a good air purifier would be a wise investment and on this page we’re going to tell you what you should look for when shopping for an air purifier.

The classroom should be installed air purifier cited hot.

As schools in Beijing and other parts of northeastern China suspend classes because of the red alert over air pollution, many parents are demanding that air purifiers should be installed for the students.

With major pollution days becoming more frequent, students are staying home, often without supervision. Their parents say it would be better if their children were in the classroom, and that’s why schools need to install air purifiers.

“Our school bought air filters last year. We did a little fund raising, with each parent throwing in several hundred for that. We’ve already bought two air cleaners for the class, both of which are installed.”

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.

What is an air purifier?

All home air purifiers are designed to help eliminate free flowing particles in the air. Although these particles are not visible to the human eye, they can trigger health problems like allergies, asthma, chemical sensitivity, headaches, and fatigue.

Air purifiers may be filter or filterless, with filterless air purifiers typically requiring less maintenance but also providing less effective filtration. Types of filterless air purifiers include electrostatic air purifiers and ionizers.

Air purifiers that use filters typically work by using a fan to pull air through a filter which is designed to capture airborne particles. The effectiveness of the air purifier depends on both the strength of the fan and the quality of the filter. The most effective filter material is HEPA (High-Efficiency Particulate Air), which removes 99.97% of particles that are 0.3 microns or larger. Complimentary technology used in the filter or unit may target specific airborne particles such as smoke, mold, or odor.

Types of Air Purifier

Type Description Effectiveness
HEPA (High-Efficiency Particulate Air) High efficiency HEPA air purifiers effectively capture airborne particles. The percent of particles captured is the highest of any air purification technology available.

High

Removes up to 99.97% of particles like dust, pollen, pet dander, mold spores and more.

Electrostatic Precipitator Particles are charged and then stick to oppositely charged metal plates within the air purifier.

Minimal

Does a poor job at circulating air. Requires frequent cleaning of the plates to maintain efficiency.

Ozone Generator Not safe and effective at removing pollutants. By design, they produce ozone, a lung irritant that can cause adverse health effects.

Harmful

Does not remove particles in the air. Ozone worsens air quality and can cause damage to lungs when inhaled.

Complementary Technology

Activated Carbon

Effective at removing unpleasant odors, gases, and chemicals in the air. Particles become attracted to, and then trapped within tiny pores in the activated carbon.

Good for: Odor, Gases, Chemicals

UV Light

Kills airborne germs, bacteria and viruses by damaging the bacteria and viruses’ DNA & molecular structure.

Good for: Bacteria, Viruses

Silver Ion Microbial Prevention Filter

Silver-infused filters capture and kill airborne microbes. Silver is naturally anti-bacterial.

Good for: Microbes, Bacteria, Viruses

Ionizer

Helps remove pollen, bacteria, odors, and chemicals in the air. An ionic-only unit provides inadequate filtration. Ionizers are added to HEPA units to improve their performance but should not be used as the sole method of filtration.

Good for: Pollen, Bacteria, Odor, Chemicals

Photo-Catalytic Oxidation (PCO)

Destroys gaseous pollutants by converting them into harmless products by the use of UV light and a catalyst (Titanium Oxide).

Good for: Gases

Pre-Filter

Captures large particles (hair, large dust particles) to extend the life of your air purifier filter.

Good for: Hair, Pet Fur, Large dust particles

Molecular Conversion Powder

Destroys tough odors like tobacco smoke at a molecular level, leaving the air smelling fresh and pure.

Good for: Smoke Heavy Odor

Thermodynamic Sterilizing System (TSS)

Destroys 99.9% of living microorganisms and proteins by exposing them to temperatures above 200 C (approx. 400F). Not available in conjunction with HEPA filtration.

Good for: Bacteria, Viruses, Mold
