The Blueair SmokeStop™ filter is the perfect choice for absorbing and removing today’s most common gaseous pollutants like VOCs, traffic exhaust, smog, odours, smoke and airborne chemicals through high amounts of activated carbon.

Thanks to the unique design of the filters and the HEPASilent™ technology, Blueair provides high airflow and efficiency with low noise and energy consumption, delivering more clean air while still being environmentally friendly.

To maintain optimum performance, it is advised to replace the filter every 6 months when used 24/7 or depending on use (4,380 hours).


HEPASilent™ technology

Blueair’s advanced HEPASilent™ filtration technology provides uncompromised particle removal. It removes at least 99.97% of all airborne particles including PM2.5, pollen, allergens, dust, pet dander, microplastics, mould spores, bacteria, smoke particles and viruses down to 0.1 micrometre in size.

SmokeStop filter

Due to its highly porous structure made of activated carbon, the Blueair SmokeStop™ filter is perfect for the removal of oil vapours, harmful gases and unwanted odours from the air.

Traps particles for good

The gradient filter structure traps particles of all sizes down to 0.1 microns while maintaining maximum airflow. It resists clogging and never re-releases particles back into the air.

Naturally antibacterial

The naturally antibacterial polypropylene-made fibres in this filter prevent bacteria and mould growth, so they are never re-released into your indoor environment again.

Environmentally friendly

Blueair filters provide quiet and environmentally friendly air purification. They are 100% recyclable, so clean air is the only thing you’ll be adding back into the environment.

6-month filter life

To maintain optimum performance, it is advised to change your filter about once every 6-months when used 24 hours a day (or 4,380 hours).

Manufacturer recommended

Genuine Blueair replacement filters guarantee the superior performance of your air purifier and ensure your warranty will stay intact.
