Classic 400 Series Particle Filter
Designed for Maximum Particle Removal
Engineered for the effective removal of all airborne particles, this filter is the ideal choice for eliminating pollutants such as pollen, dust, pet dander, and other unwanted particulates.
HEPASilent™ Technology
The HEPASilent™ filtration process from Blueair captures 99.97% of airborne particles down to 0.1 microns.
This patented technology combines electrostatic and mechanical filtration, using a unique blend of advanced filters and an encapsulated ion chamber.
The result is far superior performance compared to systems using only mechanical or electrostatic methods.
Electrostatic Particle Charging
As air passes through the Blueair purification chamber, particles are electrically charged before moving through the gradient structure of the filter.
This charge makes it easier for the filter to capture and retain airborne pollutants.
Permanently Traps Particles
Blueair’s gradient filter structure captures particles of all sizes while maintaining optimal airflow.
It resists clogging and will not re-release trapped particles, even when the filter is saturated.
The filters are ultrasonically bonded to prevent fiber shedding — ensuring the only thing released is clean air.
Naturally Antibacterial
Blueair filters use polypropylene fibers, which are naturally resistant to bacteria and mold growth.
This prevents the reintroduction of harmful microbes into your indoor environment.
Environmentally Friendly
Blueair filters are designed with lower density, requiring less pressure and energy to push air through.
They’re also fully recyclable, so the only thing you’re adding back to the environment is clean air.
Whisper-Quiet Operation
Thanks to the use of electrostatic and mechanical filtration, these filters maintain high performance with low noise.
Less dense materials allow air to flow through with minimal resistance, delivering a quiet and efficient purification experience.
