Blueair - Classic 400 Series DualProtection Filter

Product Notes:

A more efficient successor to the 'SmokeStop' GO (gas/odor) filter, this DualProtection filter is for use with the Blueair 400 series of air purifiers including (but not necessarily limited to) the 402, 403, 405, 410, 480i, 450E and 455/455EB (Costco) units.

The Blueair Classic 400 Series DualProtection Filter provides both Blueair's customary superior level of particle removal using HEPASilent™ technology – rapidly removing 99.97% of pollutants such as pollen, dust, pet dander, mold spores, viruses and bacteria down to 0.1 micron in size – and equally comprehensive but much faster gas and odor removal than before, by using pure, high quality activated coconut carbon in a powdered form with a high porosity count to remove gaseous pollutants like smoke, smog, traffic exhaust, odors (such as from cooking), PM 2.5 (fine particles less than 2.5 micrometers in diameter), airborne chemicals, and VOCs (volatile organic compounds), up to four times faster than other types of carbon filters, and without the use of any chemical additives.

Naming Note: The original Blueair 400 Series 'SmokeStop' gas and odor filters have been discontinued and replaced by these DP (Dual Protection) filters.
