Background: The quality of the environment within buildings is a topic of major importance for public health. Breathing pure and clean air allows us to think more clearly, sleep more soundly, and stay healthier. We receive 56% of our energy from the air we breathe, more than from water and food combined. On average we breathe 37 pounds of air a day1. The use of negative ions from AHPCO air purification system is an effective means of reducing the malodor causing VOCs and eradicating aeroallergens in room air.
Methods: The Wall-mount, Inducts and Mini Sanifier air purification units of Luna2 (Nano) are designed to sanitize air, to kill surface mold, bacteria, and viruses in areas up to 26,000 cubic feet. Samples were collected from the clinic rooms to analyze the VOC concentrations using the Luna air purifiers to detect the efficiency in reducing the VOCs in the indoor air. We analyzed the aeroallergens and VOCs prevalent in the indoor air in the clinics at the Coulter Animal Hospital, Amarillo, Texas3,4. The data were correlated to the inhalant allergy index before and after running air purifiers that use PCO technology.
Results:Samples from the clinic rooms to analyze the VOC concentrations using the Luna air purifiers to detect the efficiency in reducing the VOCs in the indoor air. The SKC Pocket Pump and thermal desorption tubes were used to obtain the samples from the indoor air. Pumps were set on 200 ml/min as air flow to estimate the concentration of Acetic acid, Isobutyric acid, Butyric acid, Isovaleric acid, Valeric acid, Hexanoic acid, Phenol, p-cresol, 4-ethyl, 2-amino, Indole, and Skatole. All desorption tube samples were analyzed using a Markes UNITY® and Markes Ultra® automated thermal desorber (ATD) and a Varian 3800/Saturn 2000 GC with a MS3. Slides with double sticky tape were exposed to room air stained with 2% safranin and were observed using a BX-40 Olympus microscope with DP-70 and Image Pro Plus software4.

Conclusions: The data were correlated with the aeroallergen index and the frequency of inhalant allergy cases that showed reduction in allergic rhinitis index on using air purifiers.
