The AD 3000 model covers 505 sq. ft. 5x/hour and 1262 sq. ft. 2x/hour.
Features 3-stage filtration
STAGE 1: Pre-filter for larger contaminants like dust and animal hair; can be vacuumed or hand-washed to be reused
STAGE 2: Carbon/Gas Trap/VOC filter that combines two types of media – activated carbon (1.1 lbs) to remove odors and gases (e.g., smoke) and potassium permanganate to deactivate certain volatile organic compounds (VOCs) like formaldehyde
STAGE 3: UltraHEPA filter that removes 100% of airborne particles at 0.003 microns (as compared to “ordinary” HEPA systems that remove 99.97% of particles down to 0.3 microns, Austin Air filters out 95% of particles 0.1 microns and larger.)
The UltraHEPA should be effective at filtering ultrafine particles such as mycotoxins and viruses (COVID-19).
Uses a WhisperJet fan that is potentially 30% quieter than the fans in other air purifiers
Captures mold spores but does not eliminate mold (to eliminate mold, its sources should be professionally remediated)
Filter replacement: Carbon – every 6 months, UltraHEPA filter – once a year
