The newest in Blueair's advanced filter technology, our DualProtection filters have been specifically designed for particle, gas and odor removal. An upgrade to our previously offered, Smokestop Filters, the DualProtection filters’ powdered, high-porosity coconut carbon efficiently removes gaseous pollutants like PM 2.5, smoke, VOCs, exhaust, smog, odors and airborne chemicals faster. Optimized for HEPASilent technology, DualProtection filters remove pollutants such as pollen, dust, pet dander, mold spores, viruses, bacteria micro plastics with no reduction in the clean air delivery rate (CADR).* The pure, activated coconut carbon naturally removes gaseous pollutants combined with a high-performance, high porosity, quality coconut carbon. The filter is also pleated to ensure the largest filter area possible. These combine to deliver particle removal. *Min. reduction 99.9% of S. aureus, E. Coli, H1N1, A. Niger. EPA Est. 99578-CHN-1.
