Blueair 400 Series DualProtection Filter

Uncompromised particle removal

Blueair DualProtection filters have been designed for the ultimate particle, gas and odor removal.
They are optimized for Blueair’s HEPASilentTM technology, rapidly removing pollutants with no
reduction in Clean Air Delivery Rate (CADR).
The pure, activated coconut carbon naturally removes gaseous pollutants without the need
for chemical additives. The filter is also pleated to ensure the largest filter area possible. These
combine to efficiently remove pollutants up to four times faster compared to other carbon
filters.
