How AirDoctor protects you

Advanced purification features safeguard your home's air quality.

Captures Microscopic Particles

Our UltraHEPA® filter captures  contaminants as small as 0.003 microns in size (100x smaller than the HEPA standard).

Protects With A Fully Sealed System

Our 3-stage filtration system is completely sealed, which means no contaminated air escapes back into your home.

Monitors Air Quality & Filters

AirDoctor’s filter change alerts, indoor air quality sensors, and Auto-Mode take the guesswork out of clean air.

Shields Against Airborne Threats

Eliminates 99.99% of tested viruses and bacteria, significantly reducing the risk of illness.
