Delivering more clean air, at a faster rate, with less noise.
Blueair's patented HEPASilent® technology combines the best features of electrostatic and mechanical filter technology to enable the delivery of more clean air at a faster rate with less noise. Phenomenally low power usage minimizes energy consumption. Plus Blueair air purifiers actually reduce the levels of ozone in indoor air.
How it works:
1. Air is drawn into the Blueair system via our ultra-quiet fan.
2. Airborne particles pass through an ion chamber and are electrically charged. This causes them to adhere effortlessly to our exclusive polypropylene filters.
3. Charged particles are removed in our gradient structure filter, where the first layers captures larger particles like pollen and dust. The following, gradually finer filter structure will filter out even the smallest particles like cigarette smoke and exhaust. Together, the encapsulated ion chamber and gradient structure filter combine to create Blueair’s patented HEPASilent® technology—delivering maximum airflow with minimum noise. Our GRADIENT STRUCTURE FILTER is like having multiple filters in one.
Why do Blueair filters trap 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 filters have millions of ultra thin fibers in different sizes, set in a specific order from coarse to thinner. Thus, the name progressive. The first layers captures larger particles like pollen & dust. The gradually finer subsequent fiber layers capture smaller and smaller particles down to even bacteria, virus 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 less than one minute of your time is required. Blueair filters require no weekly additives or filter washing.
