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.

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. Lift the lid and remove the top filter and then each of the side filters. Insert the replacement filters on the sides first and then the top filter. Replace the lid 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.
Free of chemical additives, this filter uses pure, high-porosity coconut carbon to remove odors. Filter fibers 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: 501, 503, 505, 510, 550E, 555EB, 580i, 601, 603, 605, 650E and 680i.
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.
Purchasing a filter subscription saves you time and effort. At the time of purchase, the subscription will automatically schedule filter deliveries at the recommended six months. You can always adjust this timeframe from the 'My Account' section.
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.
