Blueair’s exclusive HEPASilent™ filter technology is the secret to the highest levels of Clean Air Delivery Rate (CADR) and the quietest air purifier available.
Blueair utilizes special filter material and an ozone-free electrostatic ionizer that charges particles so they are magnetically attracted to the filter material. The filters contain millions of ultra thin fibers in three different sizes. Larger particles are trapped first, followed by medium and then small. This means that the filters resist loading or clogging and continue filtration at peak performance levels longer.
This dual technology explains how Blueair air purifiers trap more particles using filters that are less dense than other air cleaners. Since air flows more easily through Blueair filters, it cleans larger volumes of air with far less noise than typical air cleaners.
