Genuine Blueair filters are specifically designed to enable more air flow through the filter media. When combined with electrostatic filtration this results in faster cleaning than traditional HEPA filtration.
When it’s time to replace your filter, the Blueair app will notify you, then help you with the purchase.
Depending on usage and room conditions, your filter replacement time can vary between 6 to 12 months — but you can rest assured that with our algorithm to calculate filter life based on fan speed, particle sensor data, and estimated filter loading, you won’t be changing it too soon or too late.

Our unique HEPASilent™ filtration technology allows this filter to be less dense, meaning it requires less air pressure. With it installed, your air purifier will operate quieter while using less energy.
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.
This filter's unique structure is designed to filter high volumes of air while trapping even the smallest particles. It maintains maximum airflow because it's engineered to resist clogging.
Every aspect of this filter is engineered for wellness. It uses only pure, high-porosity coconut carbon to remove gases and odors. Filter fibers also resist bacteria and mold growth.
This filter’s extra large and absorbent surface of activated carbon removes chemicals, volatile organic compounds (VOCs), and annoying household odors from cooking, smoking, and pets.

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.
