Blueair HEPA Air Purifier Technology

Blueair HEPASilent™ Technology

A revolutionary combination of advanced filter media and an encapsulated ion particle charging chamber makes it possible for the Blueair air purification system to achieve better results than either mechanical or electrostatic technology alone.

How it works
	Air is drawn into the Blueair Air Purifier system via our ultra-quiet fan.
	Airborne particles pass through an ion chamber and are electrically charged. This causes them to adhere effortlessly to our exclusive polypropylene filters.
	Charged particles are removed in our 3-Stage Progressive Filter. Stage 1 captures larger particles like pollen and dust. Stages 2 and 3 filter out even the smallest particles like cigarette smoke* and exhaust. Together, the encapsulated ion chamber and 3-Stage Filtration Process combine to create Blueair’s patented HEPASilent™ technology—delivering maximum airflow with minimum noise.

Instead of discharging a windy stream of filtered air, the Blueair 501 and 601 diffuse air gently through an area six times greater than the average air cleaner. Operating on its lowest setting, the Blueair 501 and 601 produce virtually no noticeable draft. Blueair’s SurroundAir™ system achieves peak performance without annoying drafts by drawing in dirty air from the sides and bottom and releasing clean, filtered air from the sides and top.

3-Stage Progressive Filter

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 HEPA 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 takes only a few minutes of your time are required. Blueair HEPA filters require no weekly additives or filter washing.

Due to our exclusive design (see top figure), Blueair filters lock in particles in 3-stages. Once captured, the particles will not be re-released into your environment, even under heavy loading conditions.

Blueair's revolutionary combination of mechanical and electrostatic filtration technology captures 99.97% of particles at 0.1 micron on the lowest setting.
