Particle Filters
Blueair 3-stage particle filters trap six times more dirt than filters in typical air purifiers!
Most filters from other air purifier manufacturers are thinner and usually consist of the same size fiber throughout. Blueair's progressive filters have millions of ultra-thin fibers in three different sizes. The first layer captures larger particles like pollen and dust; the second and third capture smaller particles like bacteria and exhaust.
The progressive 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 one in. It takes only a few minutes and doesn't require screws, hooks or tools. Blueair particle filters require no weekly additives or filter washing.
These filters work with regular, E-Series, and Refurbished Blueair 200, 300, 400, 500, and 600 units.
