Blueair HEPASilent technology

Patented HEPASilent filter design

Progressive three-stage filter

Thanks to the progressive three-stage structure, Blueair filters capture six times more dirt than other air purifier filters. Our filter design resists loading or clogging and continues filtration at peak performance levels longer.

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, such as pollen and dust. The second and third layers capture smaller particles, including bacteria, viruses and cigarette smoke.

Easy to replace

When the filter needs to be replaced (typically every few months), simply open the unit, lift out the old filters and slide in the new ones. No screws, hooks or tools and less than one minute of your time is required. Blueair filters require no weekly additives or filter washing.
