*Testing was performed on an AirDoctor 3500 unit by LMS Technologies, an independent lab that specializes in air media and filter testing. LMS concluded that the AirDoctor UltraHEPA® filter removes particles as small as .003 microns, which is 100 times smaller than the particle size by which standard HEPA filters are rated in the US (99.97% at 0.3 microns under DOE-STD-3020-2005).

Unlike our competition, AirDoctor 3500 utilizes three filters to effectively clean the air your breathe!

Our Pre-Filter is designed to remove larger contaminants like dust and pet hair. This helps to extend the life of your Carbon/VOC and/or UltraHEPA® Filters.

I love my AirDoctor! I feel much more confident that the air in my home is toxin free. The filter was easy to change and customer support was very quick to respond when I had questions. Excellent investment!

Our ULTRAHEPA® FILTER will give you peace of mind,it captures contaminants 100x smaller than HEPA standard!

AirDoctor’s UltraHEPA® filters capture the ultra-fine contaminants you can’t see like dust, pollen, mold spores, smoke, pet hair, and dander, bacteria and viruses. The HEPA standard requires that 99.97% of particles at 0.3 microns are captured. AirDoctor’s 3500™ UltraHEPA® filter was independently tested and proven to remove at least 99.99% of particles as small as 0.003 microns —that’s 100 times smaller than the HEPA standard!
