We are exposed to air in all activities all the time everywhere. Most of us believe that the invisible odorless air is always refreshingly healthy. What we need in every breath we take is oxygen, and we exhale carbon dioxide in return. Plants absorb carbon dioxide through photosynthesis, and produce oxygen among other things. Some of the most common gases naturally exist in air include nitrogen, nitrogen oxide, hydrogen, argon, helium, neon, ozone, methane, xenon, and krypton. It is easy to believe that nothing else exists, but the truth is that air is full of pollutants; some pollutants are visible for examples smokes from car exhaust or tall chimney of a factory, while others have strong odor such as gas from petroleum works, waste facilities, chemical industries, contaminated soil treatment, and more.
There is another type of air pollution called particle pollution; it refers to a mix of tiny liquid and solid particles that exist in the air we breathe. The particles come from everywhere including but not limited to mechanical processes that break down bigger bits into tiny ones, construction, demolition, wear and tear of tires, roads, engines, or break pads, of cars, and dust storm. Tiny living organisms and their derivatives are also particle pollutants such as dust mites, viruses, and bacteria. Fortunately, we can prevent the air we breathe in our houses and offices from being polluted by using quality air purifiers. There are probably hundreds of air purifier brands in the market with each of them claims to be the best. Blueair, a Chicago-based air purifier company, is one of few that live up to the claim.
Blueair’s existing product lines fall into 4 categories including:
- Blueair Classic 603 - Blueair Sense+ - Blueair Pro M
- Blueair Classic 650E - Blueair Sense - Blueair Pro L
- Blueair Classic 203 Slim - Blueair Pro XL
- Blueair Classic 403
- Blueair Classic 450E
- Blueair Classic 503
It is the filter that makes the difference
One of the most common and widely acceptable standards for air filtration level is HEPA (High Efficiency Particulate Air). As defined by the U.S. Department of Energy, HEPA filters are able to remove 99.7% airborne particles with minimum diameter of 0.3 microns (a human hair measures at 30 to 120 microns). In reality, many products can have much lower particle removal efficiency of 85% and still considered HEPA-compliance. According to a report by EPA (Environmental Protection Agency) in Integrated Science Assessment for Particulate Matter, particles are grouped based on size in three categories: coarse (2.5 microns to 10 microns), fine (2.5 microns and smaller), and ultrafine (smaller than 0.1 microns). Since HEPA standard requires an air filter to remove particles sized down to 0.3 microns, it ignores ultrafine particles (UFPs).
The bad news is that ultrafine particles come from everyday household appliances and office equipment. Indoor sources of UFPs may include smoke, fax machines, laser printers, peeling of citrus fruits, cooking, vacuum cleaners, chimney cracks, combustion reactions, and penetration of contaminated outdoor air. Particles that measure at 0.1 microns (or smaller) are considered respirable and easily pass through lung tissue and circulate in the body, just like oxygen. Even if the UFPs are not highly toxic, they can still trigger oxidative stress, lung diseases, heart diseases, and other systemic effects.
All air purifiers by Blueair sets new standard for air filtration by using HEPASilent technology. It is still based on HEPA standard, but improved to utilize both mechanical and electrostatic filtration methods. The technology is a combination of an encapsulated particle charging chamber and filter media that works more efficient compared to electrostatic or mechanical filtration alone. On the lowest possible setting, Blueair air purifiers HEPASilent technology is able to capture 99.7% airborne particles measuring at 0.1 microns in diameter. It is not only HEPA-compliance, it is better than that. All air purifiers by Blueair are equipped with HEPASilent technology.
Blueair’s filters work by utilizing layers after layers of filtrations. Every filter has millions of ultra-thin fiber of different sizes; they are interwoven to create layers of progressive filter design. Particles are captured at different filtration stages, and the already captured ones are never released back. Due to its multiple-layers design, it still works efficiently even during heavy workloads. Larger particles such as dust and pollen are captured at early stages, while smaller sized particles including exhaust smokes and bacteria are captures in the later filters.
Blueair is compliant to HEPA, but it prefers to use CADR (Clean Air Delivery Rate) standard which is also endorsed by EPA and FDA. HEPA is more prominent and widely used, but CADR takes more variables into account. It measures not only the filter equipped in an air purifier, but also how filter and the air purifier work as a single unit. CADR emphasizes on the volume of clean air produced by air purifier in a minute; in other words, how well pollutants are removed. Using any Blueair purifier on the highest setting, CADR delivers much better filtration results than any system available today.
Blueair filters are recyclable, and made from antibacterial polypropylene fibers.
This is a synthetic material, but an environment-friendly one which breaks down into water and carbon dioxide. It does not require washing or weekly additives, however it requires replacement in every six months to make sure your air purifier works to its full potential. All Blueair air purifiers require no additional tool for filter replacement. Open the lid, remove the old filter, add the new one, and close the lid again. Contained in steel housing, ozone concentration produced by Blueair system is lower than the incoming air, so it is ozone-free as well.
