Independent test results prove Alen provides the best solution for the best price.Waiting for the wind to blow isn’t the only answer for smog these days with more Chinese consumers turning to purifiers for clean air. The high demand for air purifiers has created a competitive market, with as many as 300 brands now available in China. Into this battle for market share, a US-based company - the Alen Corporation - has made its debut. Alen designed its latest air purifier model to solve the problems associated with chronic air pollution in China. The company’s latest model, the Alen BreatheSmart F750 VOC, will be on sale this month. “Alen air purifiers are designed specifically to solve the toughest Chinese air quality issues” said Warburg Lee, CEO of Alen Corporation, adding that the air pollution is “obvious” when you look outside but you can also feel it in your throat after only a few days of exposure.

China and India have the world’s highest average exposure to PM 2.5, according to the 2014 Environmental Performance Index, which is jointly compiled by Yale and Columbia universities. PM2.5 - particulate matter with a diameter less than 2.5 micrometers - can go deep into the lungs and is extremely harmful to people’s health, according to the environment watchdog. With rising awareness of healthy living, purchases of domestic appliances that can improve air quality has leveraged a large share of China’s market.amaircare 1100 voc air purifier But current standards on indoor air cleaners, enacted in 2008, don’t take into consideration the need for consumers to filter PM2.5 or increased use by consumers, said Song Guangsheng, director of the National Indoor Environment and Indoor Environmental Product Quality Supervision Center.winix plasmawave 9000 air cleaner

The situation may soon change, however, because China is drafting new national standards for domestic air purifiers, industry experts said. “We applaud a higher standard and consistent with our company values of integrity, we don’t want customers to be cheated with ineffective and poorly engineered air purifiers,” said Lee. “In the US, air purifiers are generally used to address allergy, asthma, pet dander and odor issues. biogs air purifier manualBut to address chemicals like benzene and formaldehyde, a standard HEPA filter would not be enough because chemicals require different filtration technologies.”Alen’s BreatheSmart F750 VOC and F700 are based on its bestselling BreatheSmart Series product line in the US. The F750 VOC product has been redesigned and further modified to tackle benzene and formaldehyde, which are primary concerns to Chinese consumers. “The unit is specifically designed for China because air pollution is far greater here.

The sensitivity level has been adjusted to not only meet the current standard but to exceed the soon-to-be introduced air purifier standard.” Lee added that the Alen BreatheSmart F750 VOC also includes Smart Sensor technology. “Our Smart Sensor detects surrounding air quality and adjusts the fan speed accordingly in order optimize unit performance and save energy,” said Lee.I've become a bit of an air purifier nut over the years. Originally, I used them because I believed that they helped keep the dust down and my dirty home cleaner. Now, I've come to appreciate cleaner air quality while I suck it in all night. When you open it up and see how dirty the filters are, you have to be glad that you have one. With indoor air much more polluted in general than outdoor air, having a quiet, energy efficient air purifier in your home should be, in my opinion, an integral part of your home design plan. What Is a HEPA Filter (and why should I care?) In the air filter world, the HEPA standard has evolved as the go-to "good enough" quality level.

Developed originally during WWII by the Atomic Energy Commission's Manhattan Project to clean radiation out of the air, the design evolved over a number of years into an affordable, mass-produced paper filter system that could be integrated into purifiers, vacuums and other units for commercial and residential use. To qualify as HEPA by US government standards, an air filter must remove (from the air that passes through) 99.97% of particles that have a size of 0.3 µm. "HEPA: High-efficiency particulate arrestance or HEPA is a type of air filter. Filters meeting the HEPA standard have many applications, including use in medical facilities, automobiles, aircraft and homes. The filter must satisfy certain standards of efficiency such as those set by the United States Department of Energy (DOE)." via Wikipedia Here are my top picks for the year, updated from 2010. I totally believe in the super affordable fan and filter based machines, but for better filtering (particularly for odor and allergy sufferers) and quieter filtering, I would recommend spending more.

Kenmore 83394 Small Room HEPA Filter Air Purifier Spoken of highly by readers, this Sears Kenmore series, available in three sizes, is the most affordable HEPA air purifier that I'm including on the list. It features a sleek, wall hugging design, quiet operation, an EnergyStar rating and a two-filter system that covers up to 400 square feet. I like Honeywell, and I've also had two of these purifiers for a number of years in our many roomed family house in the country. Big, not particularly quiet (great white noise, however, for sleeping babies & adults), I find the Honeywell purifiers to be simple with very good HEPA filters at a very good price for basic air filtration. This purifier is rated to clean a room up to 390 square feet (smaller than RabbitAir) and is not for continuous air cleaning as it's too loud and not an energy saver. Coway AP-1512HH Mighty Air Purifier with True HEPA and Eco Mode Rated super highly by The Sweethome, Coway is a name I hadn't heard before, but its products are given high marks for air cleaning at a very good value.

Said to be as good as machines twice the price, the Coway Mighty is a small, sleek unit that runs silently, uses very little energy and works with easily replaceable filter panels similar to a RabbitAir machine. It will efficiently clean a 325 square foot room. What Happened To Air Ionisers??? Famous just a few years ago for being slim, silent and able to clean the air without a breeze (remember how popular they were among those that needed to clear the air quickly in their parents' house?), air ionisers have faded in use because two things happened. The first was that ionisers were discovered to produce small amounts of ozone, a toxic gas, which set off a health scare and made them persona non-grata in the medical community. Secondly, and more importantly, ionisers have never proven to clean air and move it through the room as well as traditional HEPA filters. Famously, in 2003, Consumer Reports gave The Sharper Image's popular Ionic Breeze a "fail" rating, which set off a lengthy court battle.

In the end, Sharper Image lost the case when it couldn't prove any of Consumer Reports assertions to be untrue. That said, ionizers have found their way into many HEPA machines as a way of adding extra filtering power. RabbitAir BioGS 2.0 Ultra Quiet Air Purifier Designed by Guto Indio da Costa in 2014, this purifier won the Good Design Award and the RedDot Award in that year. This (and the MinusA2 Ultra Quiet Air Purifier a few products down) are me two top picks of all the machines on this list. I have them at home, and I find them to be compact, powerful and silent. Mine runs continually on low and I've had it for three years without any problems. Since its inception, Dyson has always been known for breaking the mold with its innovative products. Consider this the air purifier of the future. With the corresponding app, the machine monitors the humidity, air quality and temperature of the room it's in and reacts accordingly, reporting all stats back to you via your smart phone.

It promises to remove 99.97% of allergens and pollutants as small as 0.3 microns. RabbitAir MinusA2 Ultra Quiet Air Purifier SPA-780A Black This is the more expensive of RabbitAir's offerings, and it's the one that I have had for years. The MinusA2 sits flat against any wall or piece of furniture, runs absolutely silently and comes with a choice of four different filter systems: Pet Allergy, Odors, Toxins or Germ Defense (they all seem good to me). The unit sips energy with an EnergyStar rating (as low as 7 watts), is a true HEPA filter and covers from 700-815 square feet at normal filtration levels (cleaning for an allergy sufferer reduces the square footage to about half). Alen BreatheSmart Customizable Air Purifier with HEPA-Pure Filter for Allergies and Dust , it also has a near perfect 5-star rating on Amazon. Cleaning up to 1,100 square feet, it covers more space than any other purifier on this list. Like the Dyson air filter, it automatically detects and adjusts to fluctuating air quality.

Fully customizable, buyers get the choice of 4 HEPA filters (Pure, Silver—which is best for allergy sufferers, OdorCell, FreshPlus.) Also, for the design aficionado, the BreatheSmart is offered in 15 front panel options, one of them that you can custom paint to make your walls.Founded in the '90s, Stockholm-based Blueair pairs a high standard of filtration with a sleek, Scandinavian design. With a large range of excellent machines at prices from medium to very high, Blueair features HEPA filtration, galvanized steel casing, super quiet operation, no drafts, extreme energy efficiency, and an argument for the highest Clean Air Delivery Rate (CADR) on the market, which means it will move air more quickly as it cleans. The Classic ECO10 shown here will handle 220 square feet. IQAir New Edition HealthPro Plus IQAir has a great history as it was founded by two brothers, Manfred and Klaus Hammes, who were early pioneers in the '60s developing paper-based filters to eliminate coal dust coming out of ovens in German homes.
