Pure, high-porosity coconut carbon efficiently removes gaseous pollutants from your home 4x faster than other Blueair filters, including household chemicals and cleaners, volatile organic compounds (VOC) and odors from pets, cooking, and smoking.
³Based on Blueair internal tests
Unlike generic look-a-likes, genuine Blueair replacement filters are specifically designed to maintain superior performance over time and ensures your warranty remains intact.
When it's time to replace your filter (about every six months), start by unplugging your air purifier. Open the back door to remove the old filter and vacuum away any dust on the inside. Insert the replacement filter, close the back door, and plug back in. Easy.
Our unique HEPASilent™ filtration technology allows our filters to be less dense. Less dense filters require less air pressure— resulting in quieter and more energy efficient air purifiers.
In addition to removing gases and odors, DualProtection filters are highly efficient in eliminating airborne particle pollutants from your home, including allergens, pollen, dust, mold, pet dander, viruses, and fine smoke particles.
The filter structure traps even the smallest particles and resists clogging to maintain maximum airflow.
This filter is 100% recyclable, so the only thing you're adding back into the environment is clean air.
Free of chemical additives, this filter uses pure, high-porosity coconut carbon to remove odors naturally. Filter fibers naturally resist bacteria and mold growth.
To maintain optimum performance, we recommend changing your filter about once every 6-months when used 24 hours a day.

This filter is compatible with the following Classic family models: 203, 203 Slim, 205, 270E, 270E Slim, 280i
Classic DualProtection filters feature a highly-porous, lightweight carbon mesh that is extremely efficient at removing both particle and gaseous (odors, exhaust, smoke odors, and chemicals) pollutants from the air. Whereas Classic Particle filters are highly efficient in the removal of particle pollutants like pollen, dust, mold, viruses, and fine smoke particles.

No, Blueair filters are less dense than traditional HEPA filters, allowing our air purifiers to be quieter and more energy-efficient. Instead of HEPA filters, we use a combination of electrostatic and mechanical filtration that we call HEPASilent™ technology to achieve the same level of filtration efficiency - with less energy and noise.
