ABOUT LG Welcome Sign out / Find a Repair Provider Find Accessorise & PartsUPDATE, March 2015: Please check out my buyer’s guide to air purifiers; my 2014 review of the science behind air purifiers; my 2015 tests of air purifiers under 1,000 RMB plus my 2014 review of two dozen top air purifier models in China. Beijing’s internet forums are always filled with heated debates as to which air purifier is best: IQAir vs Blueair vs others;

I finally decided to jump into the fray and enter the great debate. As I’ve mentioned in many posts, I am a big fan of indoor air purifiers because I think indoor air pollution is a serious public health concern here in China. And while indoor plants can help a lot, I think the machines are far more effective. So, which machine should you buy — if any? I personally use three brands; in my small office I have a Hunter 31125, which is a true-HEPA filter. It’s Taiwan-made from the American company Hunter, and I bought it for around 1248RMB at the Sundan electronics store at the Sanlitun Village mall basement. At home, we have two machines which are also HEPA filters; the bedroom has the Blueair 501 which we bought for around 6,000RMB, and the living room has an IQAir 250, which I believe was around 11,000RMB. Real World Tests: Blueair 501 vs IQAir 250 Last year I borrowed an air particle monitor from IQAir and did a lot of spot checks at home to check out which purifier at home — my IQAir or Blueair — worked best.

My den (living room) is about 40+ square meters, and my bedroom is ~20 square meters. Both of my machines’ filters were a couple months old. The original data is in the table below (note that “%” means “percent of that room air versus current outdoor air”). You can parse (spin?) the data many ways, but here are my conclusions: My Hunter Did Very Well My smaller air purifier, the Hunter 31125 in my small office, also did quite well. It routinely got 50-70% of pollution even with the constant door opening. At max speed with the door closed for a while, it got 91% of the pollution. I think this is a great option for small rooms, and at 1290RMB is far cheaper and smaller than the other brands. Real World Reviews: Survey Says… Readers should definitely read the most objective sources out there and try to avoid the many “review” sites which are essentially shills for selling particular brands. One reputable consumer group, which is free, is the Consumer Search group.

In their reviews of air purifiers, they list: This website has a ton of good info and links to the most reputable reviews, so readers should definitely use this website. The magazine Consumer Reports also has an excellent reputation for reviews; interested people would need to pay online to download their review of air purifiers, but a tiny one-month charge is nothing compared to the thousands you may spend on machines, and their advice is highly regarded.air duct cleaning houston cost I would love to endorse a locally made brand such as one from China’s reputable brand Yadu, but I’m simply not aware of any good research, at least available in English. small air purifier for dustIf anyone has such information, please share with readers in the comments section below.guardian air purification system price

The Bottom Line: It’s All A Cost-Benefit Analysis So here you are with all this information, and you need to decide. The biggest factors are quality and cost. Buying imported seems to be a no-brainer, at least for now. In my real-world tests, I didn’t see much difference at all between Blueair and IQAir. IQAir does have many good reviews out there but the price difference is a serious issue for many; it’s less of an issue if you plan to resell, since the resale value is high. I think the next level under these two brands are the highly regarded but less locally available models from AlenAir, Austin Air, and Honeywell. I’ve read on the Beijing blogs that some are happy with Alen Air, which has an easy website in English and ships for free from Hong Kong. (I think World Health Store just started to carry Alen Air?) Last but not least; do not buy ozone-creating purifiers that ionize the air. This was trendy a few years ago, but there is now excellent data that ozone itself is an indoor hazard.

No reputable company or reviewing magazine recommends ozone-creating ionizer machines anymore.

Air Purification for Hong Kong that Meets WHO Indoor Air Quality StandardsAir Purification to WHO IAQ Standards The World Health Organisation has designed official air quality guidelines (IAQ – Indoor Air Quality) to offer a common standard for reducing the health impacts of air pollution worldwide. Air purification to WHO IAQ standards means a significant reduction in the levels of pathogens and toxic substances generated indoors (everything from building material fumes to cooking stove gases) as well as air from outdoors.

Air quality standards are set by each country to protect the public health of their citizens and are an important component of national risk management and environmental policies. National standards will vary according to the approach adopted for balancing health risks, technological feasibility, economic considerations and other political and social factors, which in turn will depend on the level of development and national capability in air quality management. Air purification to WHO IAQ standards varies in relation to each individual region in which the Organisation operates. For example, the guide published by the WHO’s Regional Office for Europe has extensive separate guidelines for biological pollutants, chemical pollutants, tobacco smoke and more. Based on regular reviews of international medical and scientific evidence, a range of the most common indoor air pollutants has been identified. These include suspended particulates, toxic gases but also viruses, bacteria and mould.

The guidelines stipulate the safe levels for these pollutants and Health and Environmental Ministries adopt these standards around the world. At present and according to our knowledge, Oxyvital air quality systems are the only air purification technology in the market tested and proven to provide air purification to WHO IAQ standards. Read More >Health Hazards of Indoor Air PollutionAll of us face a variety of risks to our health as we go about our day-to-day lives. Driving in cars, flying in planes, engaging in recreational activities, and being exposed to environmental pollutants all pose varying degrees of risk. Some risks are unavoidable; some we choose to accept because to do otherwise would restrict our ability to lead our lives the way we want. And some are risks we might decide to avoid if we had the opportunity to make informed choices. In the last several years, a growing body of scientific evidence has indicated that the air within homes and other buildings can be more seriously polluted than the outdoor air in even the largest and most industrialized cities.
