Airocide PPrm contains the same NASA-developed photocatalytic oxidation technology that is used in a variety of Airocide product lines. In addition to serving the floral and perishable preservation and food safety industry, the Airocide technology is has been developed to kill/remove/eliminate airborne pathogenic and non-pathogenic microorganisms in vegetative and spore states (bacteria, mold & fungi, viruses and dust mites), allergens, odors and harmful volatile organic compounds (VOC’s ) in air in a variety of commercial, government, and residential market applications including the medical healthcare industry (Airocide is listed as an FDA Class II Medical Device).
A clinical study of the Airocide PPT airborne pathogen killing technology was conducted in the wine barrel storage room of Chateau St. Jean. Founded in 1973 and now owned by Foster’s Group, Chateau St. Jean is a wine making estate located at the foot of Sugarloaf Ridge in the Sonoma Valley near Kenwood, California. The data supports the hypothesis that airborne mold levels would be lowered after 21 days of continuous operation of the Airocide PPT system. The results show an average airborne mold reduction inside the storage room of 57% in 23 days.
The barrel storage room used in this study was approximately 130,000 ft3 in volume. The
Airocide PPT system in the study consisted of four (4) ACS-100 units located throughout the room.
The test period consisted of 21 days in July and August 2005. Baseline air samples were taken in the barrel storage room without the Airocide units operating and were compared to Active On samples taken in the same locations after 48, 72 and 96 hours of Airocide use as well as after 23 days of Airocide use.
During the test period, air handlers (HVAC) and two circulation fans were operating. Outside venting fans were turned off. Air samples were taken with a slit air sampler (similar to the Anderson N6 sampler) on 15 x 100 mm plastic petri dishes. All samples were cultured on Potato Dextrose Agar plate by Aerotech Laboratories in Phoenix, AZ, and the results were measured in colony forming units (CFU) per cubic meter of air. All agar plates were exposed to 28.3 Um of air for 3 minutes.
The table below shows overall airborne mold reduction inside the cooler of 57% in 23 days.
