The Air Doctor air purifier 5000 model covers 868 sq. ft. 5x/hour and 2170 sq. ft. 2x/hour.
Features dual 3-stage filtration
STAGE 1: Two pre-filters for larger contaminants like dust and animal hair; can be vacuumed or hand-washed to be reused
STAGE 2: Two Carbon/Gas Trap/VOC filters that combine two types of media – activated carbon (1.65 lbs each, 3.3 lbs in total) to remove odors and gases (e.g., smoke) and potassium permanganate to deactivate certain volatile organic compounds (VOCs) like formaldehyde
STAGE 3: Two UltraHEPA filters that remove 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 particulate matter such as mycotoxins and viruses (COVID-19).
Uses a WhisperJet fan that is potentially 30% quieter than the fans in other air purifiers
Does not produce measurable ozone
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
