Blueair 400 Series Particle Filter

An air purifier cannot succeed on clean form and outward design alone. In order to achieve the most comprehensive clean air solution possible, you need the best particle filter available. The Blueair 400 series Particle Filter is the perfect companion to any Blueair 400 Series machine.

HEPASilent particle filtration works in conjunction with the ionization chamber built into each Blueair device. These filters are designed with fibers that are looser-knit than what is found in most competing air filtration systems and they work by trapping harmful particles through electrostatic attraction. With a more open fiber knitting, HEPASilent filters by Blueair can allow for increased airflow, resulting in faster cleaning and lower energy consumption. The filters are also constructed with a 3-stage design that allows the progressively tighter-knit polypropylene fibers to entrap 99.97% of any pollutants, down to 0.1 microns in size.  Blueair particle filters are proven capable of capturing every type of airborne pollutant, including pollen, mold spores, dust, pet dander, allergens, bacteria, and viruses. HEPASilent filters have consistently been called the most valuable filters for those with allergies, asthma, or other respiratory ailments.

Blueair has designed this filter to fit the 400 series of air purifiers.
