Filtration Technology

The Purairia uses a True HEPA filtration system that captures 99.97% of airborne particles as small as 0.3 microns, covering common allergens like pollen, pet dander, dust mites, and mold spores. The side intake technology draws air efficiently from the room.

However, the unit lacks a dedicated activated carbon stage, which means it is less effective at neutralizing gases, VOCs, and persistent odors compared to purifiers with multi-stage HEPA and carbon filtration.
