Upgrade your air purification setup with the Blueair DualProtection Filter, specifically designed for Classic 200 Series and 400 Series air purifiers. This high-efficiency filter combines Blueair’s HEPASilent™ filtration technology with an advanced coconut-based activated carbon layer to deliver unrivaled removal of both particles and gas-based pollutants — including pollen, dust, pet dander, bacteria, mold spores, smoke, VOCs, and odors.

Unlike traditional filters, this unit offers 4x faster removal of gaseous pollutants with zero impact on CADR. Its gradient-structured, pleated media maximizes surface area for better airflow and durability. Naturally antibacterial polypropylene fibers help resist mold and bacterial growth, ensuring only clean air is released.

Environmentally conscious and energy-efficient, the filter’s low-density structure minimizes energy use while maintaining whisper-quiet operation — making it ideal for homes, offices, and allergy-sensitive environments.
