BLUEAIR Classic 400 Series Genuine DualProtection Filter

The newest in Blueair's advanced filter technology, our DualProtection filters have been specifically designed for particle, gas, and odor removal. Optimized for HEPASilent technology, DualProtection filters remove pollutants such as pollen, dust, pet dander, mold spores, viruses, bacteria, and microplastics with no reduction in the clean air delivery rate (CADR).* These filters are an upgrade to our previously offered Smokestop Filters, with the DualProtection filters' powdered, high-porosity coconut carbon efficiently removing gaseous pollutants like PM 2.5, smoke, VOCs, exhaust, smog, odors, and airborne chemicals faster.

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, further contributing to the particle removal. These features combine to deliver efficient particle removal.

The DualProtection filters with an activated coconut carbon layer naturally remove odor-causing VOCs and smoke, while the particle filter captures pollen, dust, pet dander, mold spores, viruses, and bacteria.* These filters offer up to 4 times faster pollutant removal than other carbon filters.

The Genuine Blueair Replacement Filter is compatible with Blueair Classic 402, Blueair Classic 403, Blueair Classic 410, Blueair Classic 450E, Blueair Classic 455EB, Blueair Classic 405, and Blueair Classic 480i. It is recommended to change the filter once every 6 months.
