If you have allergies, asthma, hay fever or simply want to maintain clean air at home, replacing your Blueair 400 Series filter every six months keeps your purifier performing as it should. This genuine particle filter removes 99.97% of airborne particles down to 0.1 microns — pollen, dust, pet dander, bacteria and viruses — using Blueair's HEPASilent technology.
Genuine performance, superior quality Unlike generic look-alikes, genuine Blueair replacement filters are specifically designed to maintain superior performance over time and ensure your warranty remains intact.
Uncompromised particle removal Particle filters minimise allergy triggers, viruses, and bacteria for a healthier home environment. Together with HEPASilent™ filtration technology, this filter removes 99.97% of airborne particles down to 0.1 microns, including pollen, dust, pet dander, mould spores, viruses, bacteria and fine smoke particles.
Less dense filters make the difference Blueair's unique HEPASilent™ filtration technology allows filters to be less dense, requiring less air pressure — resulting in quieter and more energy efficient air purifiers.
Traps particles for good The filter structure traps even the smallest particles and resists clogging to maintain maximum airflow.
Prevent bacteria and mould Filter fibres resist bacteria and mould growth, ensuring you never put bacteria or mould back into the air.
6-month filter life To maintain optimum performance, replace your filter approximately every six months when used 24 hours a day.
How does this filter differ from the 400 Series SmokeStop filter? The standard particle filter is highly efficient at removing particle pollutants — pollen, dust, mould and viruses. The SmokeStop filter does all of this but adds activated carbon to also remove gaseous pollutants such as cigarette smoke, traffic exhaust, VOCs and household chemicals.
