Dyson first made a name for itself with bagless vacuum cleaners more than 20 years ago, and has since launched everything from fan heaters and air multipliers to hand dryers and washing machines. Today, Dyson is lifting the lid on the next product category to emerge from its vaults: air purifiers. The U.K-headquartered company quietly unveiled the Dyson Pure Cool in Japan a couple of weeks back, but it won’t be available to purchase there until April 7. Today, however, represents the product’s first official launch, kicking off in China, a country that has long been plagued by pollution, with an estimated 1.2 million premature deaths attributed to bad air according to a 2010 Global Burden of Disease study. There is a similar situation in Japan too. While air pollution is one of the main reasons behind Dyson’s launch market strategy, we’re told that other countries around the world will be able to buy the product in the future, including the U.S., which isn’t impervious to air pollutants either.

The Dyson Pure Cool uses a 360-degree glass high-efficiency particulate arrestance (HEPA) filter, which it claims removes “99.95% of harmful ultrafine particles from household air.” It uses the same technology from the Dyson Air Multiplier fans to help circulate the resulting clean air around a given space. Some studies suggest that ultrafine particles (UFPs) — that is, particles of 100 nanometers (NM) or less in size — emitted from the likes of car exhausts can lead to heart disease and other ailments. So those living near traffic congestion, in particular, are the key target market for Dyson here. “There is more in the air than meets the eye – the really harmful pollutants are those we can’t see,” explains James Dyson, founder and chief engineer at Dyson. “Throughout the development of Dyson Pure Cool, Dyson engineers focused on capturing the ultrafine particles that can travel deep into your lungs – developing a machine which captures particles as small as 0.1 microns.”

In terms of pricing — well, the Dyson Pure Cool isn’t cheap. VentureBeat has been given two prices for the contraption, one in Japanese yen (¥69,984) and one in Chinese yuan (RMB 5,190), but when converted into U.S. dollars, the prices range widely, from $580 to $830 respectively. Still, this gives us an idea of what to expect when it launches in other markets — it’s safe to assume that it will be somewhere in the $500-$700 price range.mass airflow sensor cleaning vw jetta While the company’s decision to launch in Asia first is partly down to the inherent air pollution problems, there is more to it than that — the Dyson brand is big in Asia. homedics air purifier reviewsIn Japan, Taiwan, Singapore, and Hong Kong, Dyson claims that it’s now the leader in the floor-care market. air duct cleaning simi valley ca

China too is growing. A spokesperson tells VentureBeat: Growth in China in particular is strong — at current growth rates, China can soon become Dyson’s bestselling market — we tripled the size of our business there in 2014. In Taiwan, January sales were up 250 percent compared to the year before. We hope that this new Dyson technology will accelerate this growth. Two weeks back, Dyson revealed a $15 million investment in solid-state battery company Sakti3, representing one of the first investments to emerge from the $2.3 billion fund it set aside to invest in “future technologies,” this includes $1.5bn specifically for research and development around new product categories.HEPA air purifiers are top of the line and used by allergy and asthma doctors to alleviate the harsh symptoms of these conditions. Discover the best HEPA air purifiers that use HEPA technology to address Asthma and Allergy symptoms. History of HEPA Air Purifier Technology In the 1950s, the US Atomic Energy Commission needed something to remove small radioactive particulates, so High Efficiency Particulate Arresting (HEPA) filters were developed.

Since then, HEPA filtration has been used in air purifiers to clean the indoors in spaces like medical cleanrooms and beauty salons. HEPA products are also part of treatments used by doctors to help alleviate allergy and asthma symptoms. What is a HEPA air purifier? HEPA air purifiers are top of the line and used by allergy and asthma doctors to alleviate the harsh symptoms of these conditions. Imagine a filter that only allows very tiny particles to pass through. If we place a single sheet of this HEPA material in front of a fan, constrained as it would be in air purifiers, very little air would be able to pass because of the small size of the holes. Due to the high performance of HEPA air purifiers, the filter will need to be changed often, as the small holes rapidly catch particles. Doubling the size of the HEPA filter sheet would allow twice the airflow and filter life. Moreover, folding the sheet back and forth in a zig-zag formation will then present a very large surface area for airflow;

this design is how HEPA air purifiers are so efficient and effective. Authentic HEPA filters and HEPA air purifiers may require as much as 40 square feet of the HEPA filter material. HEPA material is typically constructed as fiber, paper-like, or polymer. HEPA material looks like a very thin bail of fibers. Air has to find a route through this maze of fibers, and there are three steps in the HEPA filter process of trapping particulates. First, a particle runs into the fiber and sticks. Then, the particle gets within one diameter of a fiber in the HEPA air purifier; while it tries to get by the fiber it becomes stuck to the fiber. Finally, as a very small particle (about 0.1 micron) moves in the gas flow, it dithers about due to collisions with molecules (Brownian motion); the particle slides close to the fiber and becomes caught. This is how HEPA air purifiers stop mold spores, as well as many bacteria, viruses, and dust. Top performing HEPA air purifiers, like the Alen A350 air purifier, remove at least 98% of particles (0.3 microns and larger).

However, pure HEPA air purifiers do not remove odors, chemicals, or gases, unless combatting them specifically with add-on technologies. These are molecular level substances, and the holes of the HEPA material are large compared to the gas molecules, allowing them to pass through. Advanced HEPA air purifiers are engineered to target odors by using activated carbon to absorb odors and chemicals as the air passes through the air purifier. Activated carbon levels will vary depending upon the unit. The substantial amount of activated carbon in a HEPA AllerAir air purifier, for example, allows it to effectively capture chemicals, gases, and odors. The carbon absorbs gases that will not be caught by the HEPA air purifier alone. Alen and Blueair air purifiers are also brands that use activated carbon in combination with HEPA filtration to provide light odor coverage. We also offer heavy duty filters to remove odors, smoke, chemicals, and gases. Alen and Blueair use an advanced approach to HEPA filtration that makes their air purifiers especially efficient.
