Blueair Particle Filter for 400 Series

A revelation in air purificationHEPASilent technology unites the best in electrostatic and mechanical filtration. The revolutionary combination of advanced filter media and an encapsulated particle charging chamber ensures that Blueair purifiers deliver results far superior than either mechanical or electrostatic technology alone. Even on the lowest setting, our air purifiers capture 99.97% of airborne particles down to 0.1 micron in size. Particles captured on contactBlueair filters work like many filters in one. Millions of ultra-thin fibers of different sizes and layers are interwoven to create the progressive filter design. Locking in particles at different stages, captured particles are never released back into your home or office environment, even when filters are heavily loaded. The early layers capture larger particles like pollen and dust. Later filter layers capture smaller bacteria and exhaust particles.Environmentally friendlyPolypropylene is an environmentally responsible synthetic, which ultimately breaks down into carbon dioxide and water. A naturally antibacterial material, our filters will only captured mold particles from the air, never grow their own.High performance, low maintenanceUniquely designed to resist clogging and promote peak filtration performance, HEPASilent technology brings high efficiency and longer lasting air flow to air air purification. Replacing the filter approximately every six months is as simple as opening the lid, removing the old filter and sliding in the new one. No screws, hooks or tools needed. In under a minute you will have a new filter in place. Plus, our filters require no weekly additives or filter washing. Other filters can lose air-flow performance in just months.Creating an ozone-free zoneUsing a very low electric current, Blueair purifiers don't produce ozone. In a sealed steel housing chamber, testing proves that the ozone concentration in our systems output air is lower than in the incoming air.
