Choice of Two Types of Filters
|
In addition to the HEPA particle filter,
Blueair air purifiers
give you the choice of an additional SmokeStop or Gas filter for use with the
particle filter, for optimal air quality depending upon your environment and specific
needs.
Particle
Filter: Removes many airborne allergens and lung
damaging pollutants such as house and textile dust, pollen, smoke, cat and dog dander,
dust mites and their feces, automobile exhaust, soot particles from laser printers and
copiers, bacteria, fungus and mold spores. Blueair air purifiers reduce odors, too. The
particle filter is made of a polypropylene material that mechanically filters out airborne
particles. To maximize filter effectiveness, particles are bombarded with a negative
electrostatic charge as they are drawn toward the filter.
SmokeStop
Filter: Combines the particle filter with an
enhanced active carbon filter for heavy-duty odor control. This filter is best suited for
use in areas that may fill with heavy gaseous pollutants, such as cigarette and cigar
smoke.
And changing filters is fast and easy. Simply remove the
top lid.

How well an
air purifier works depends on the percentage of pollutants removed as air goes
through the filter system combined with the amount of air that goes through
the unit. In other words, you want a unit that cleans a lot of air extremely
well!
To help
consumers evaluate air purifiers, AHAM (the Association of Home Appliance
Manufacturers) devised a test that evaluated the combined effectiveness of
filtration and capacity. The test results are expressed in Clean Air Delivery
Rate or CADR. This is the test that the American Lung Association and the EPA
look to as a standardized test for evaluating the performance of air
purifiers.
What the CADR
tells you is the amount of 100% clean air that is coming out of an air
purifier. Of all the units tested by AHAM, Blueair had the very highest test
results in their room size capacity. This means that no other unit delivers as
much fresh, clean air into your environment as Blueair!
And we're
talking about a lot of clean air, too. Without getting too technical, in a
home with smoke pollution, having a Blueair operating is like adding
380 cubic feet of 100% clean air to the room every minute!
And the
Blueair performed outstandingly on the two other test materials, too. For dust
and pollen pollution, the Blueair adds 390 cubic feet of clean air per minute!
Only these materials were incorporated in the AHAM tests. But there's every
indication that the exclusive Blueair technology provides similar rates of
clean air on a wide range of indoor pollutants.
Not only does
the Blueair have amazing CADR performance; it can handle large spaces, too.
AHAM recommends the Blueair 501 for rooms up to 550 square feet (22 x 25
assuming an 8' ceiling)! This means that even in a room this size, the Blueair
501 provides a complete air exchange every 11 1/2 minutes!
