Blue by Blueair Pure 211 Combination SmokeStop Filter

The Blue by Blueair Pure 211 Combination SmokeStop Filter features an active carbon mesh for extra odor and gas removal. The active carbon captures and removes VOCs and gases from the air, so you're left with fresh, clean air. It also removes smog, sand, dust, pollen and other small particles from the air. The Pure 211 Combination SmokeStop filter is 100% recyclable and should be replaced every 6 months when it is used for 24 hours every day. This filter is for use with the Blue by Blueair Pure 211 air purifier (it does not work with the Blue 211+ air purifier).
