Why do Blueair filters trap six times more dirt than filters in typical air purifiers?The
reason is the filter’s progressive structure. Most filters from other
air purifier manufacturers are thinner and usually consist of the same
size fiber throughout. Blueair filters have millions of ultra thin
fibers in three different sizes. Thus, the name progressive. The first
layer captures larger particles like pollen & dust. The second and
third capture smaller particles like bacteria and exhaust.
Our filter design resists loading or clogging and continues
filtration at peak performance levels longer. When the filter needs to
be replaced (every six months), just open the lid, lift out the old
filters and drop the new ones in. No screws, hooks or tools and less
than one minute of your time is required. Blueair filters require no
weekly additives or filter washing.
All Blueair units are testedand verified 100% ozone free.
