The newest in Blueair's advanced filter technology, our Dual Protection filters have been designed for the ultimate particle, gas and odor removal. An upgrade to our previously offered, Smokestop Filters, the Dual Protection filters’ powdered, high-porosity coconut carbon efficiently removes gaseous pollutants like PM 2.5, smoke, VOCs, exhaust, smog, odors and airborne chemicals up to four times faster compared to other carbon filters. Optimized for HEPASilent technology, Dual Protection 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 without the need for chemical additives. Just a high-performance filter composed of sustainably sourced, high porosity, high-quality coconut carbon. The filter is also pleated to ensure the largest filter area possible. These combine to deliver uncompromised particle removal. EPA Est. 99578-CHN-1
