The next generation of advanced carbon filters, Blueair’s DualProtection filters achieve ultimate particle, gas and odor removal. This filter replaces the previously available, Classic 500/600 Series SmokeStop filter.

Uncompromised particle removal
Advanced HEPASilent™ technology rapidly removes pollutants such as PM 2.5, pollen, dust, pet dander, mold spores, viruses, bacteria, microplastics, and more- with no reduction in Clean Air Delivery Rate (CADR).

Faster gas and odor removal
Building on the highly efficient gas and odor removal of Blueair’s SmokeStop filters, DualProtection takes this technology to the next level, removing gaseous pollutants faster than other carbon filters.

No chemical additives
The pure, high-porosity coconut carbon is free of chemical additives and highly efficient at removing gaseous pollutants like VOCs, exhaust, smog, smoke and annoying odors from pets, smoking, cooking, wildfires and more.
