A.I.R. Device Effectiveness
Testing results show that the A.I.R. device provides 99% sanitization of mask filter when used in heavily contaminated air. For this test a 3M 6001 filter cartridge was exposed to a closed area with visible surface mildew contamination. For control test the cartridge was connected to an Impact Instruments Model 317M vacuum pump to pull a constant draw of air through the filter for 15 minutes. The pre-filter cloth was then removed and swabbed directly to Agar Plate (65.3% Agar, 21.7% Pancreatic Digest of Gelatin (Peptone G), 13% Beef Extract). The new cartridge pre-filter was then replaced with a new unit and the A.I.R. device attached to the filter and same conditions were tested- 15 min vacuum through filter assembly in contaminated space. The pre-filter cloth was then removed and swabbed directly to Agar Plate. After 48 hours results show almost complete neutralization of the contamination on the A.I.R. plate when compared to the control.
