Eradication of Indoor Aeroallergen Using a 3000 Xtreme Air Purifier.

Experimental trials at the Allergy AARTS Clinic at Amarillo revealed that the Allergic Rhinitis patients showed susceptibility to air spora, including Alternaria, Cladosporium, Curvularia, Pithomyces. We standardized the procedure to assay the efficiency of the air purifier Xtreme 3000 in reducing the indoor aeroallergen. Distance: Sets of the Petri plates and coated slides were placed with those distances of 1foot, 2 feet, 4 feet, 6 feet and 12 feet away from the air purifier. Time Period: Exposure after 24 hour, 48 hour and 72 hour treatment. The control Petri plates and slides were placed in the room without using the air purification system. Assay was done with the Petri plates prepared from Brain Heart Infusion agar (VWR) and Gelvatol coated slides with air purifier off for the control and on for the treated. The slides were examined, analyzed, and photographed using a BX-40 Olympus microscope attached to a DP-70 Digital Camera. Petri plates were examined with an SZ-40 stereo-scope to observe and count the colonies. The control set of plates showed vigorous growth of the microbial colonies after incubation in an incubator at 37oC for 24hours. Petri-plates closer to air purifier (2ft. and 4 ft.) produced least number of colonies after 24h., 48h. and 72 hours of treatment of the indoor air with the air purifier. There was very minor trace of inoculums from the Petri-plates from 2 ft. 4ft. and 8 ft. after 24 hours. After 72 hours of treatment of the indoor air with the air purifier there was very little microflora or propagules left in the indoor air since there were only 1-2 microbial colony produced on the Petri-plates. After a 2-month continuous exposure of the room air with the Xtreme 3000 at "High" setting we found complete eradication of aeroallergens including the fungal and bacterial spores.
