•Additional activated carbon removes 99.9% of wildfire emissions for extra protection against smoke, toxic gasses, smog and odors.
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. Turn the top portion of the air purifier counterclockwise to remove.
Take out the old filter and vacuum away any dust on the inside. Insert the replacement filter, replace the top/cap 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.
The particle filter layer helps to minimize the airborne particles that can trigger allergy symptoms, including pollen, dust, mold spores, pet dander, viruses, bacteria, and fine smoke particles.
A layer of activated coconut carbon absorbs light gases, including volatile organic compounds (VOC), smog, chemicals, and annoying household odors from pets, smoke, and cooking.
This filter is recyclable, so the only thing you're adding back into the environment is clean air. Please check your local recycling facilities for availability.
To maintain optimum performance, we recommend changing your filter about once every 6-months when used 24 hours a day.
The filter structure traps even the smallest particles and resists clogging to maintain maximum airflow.

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.
