Case Studies
Spores that pass through the box aren't filtered, they're fried," says John Hayman, Chief Science Officer for Akida Holdings, the manufacture and marketer of Airocide. "That's appealing," he notes, "for people who don't want to change an Anthrax-laden air filter."
A total of 60,865 spores entered the reactor and of this inoculum, a total of 5 CFUs exited the devide and were collected on the surface of the seven sets of blood agar plates over the 70-min sampling period. After each 10-min sampling period culture plates were covered and labeled. A total of 14 culture plates were incubated overnight at 35 degrees Celsius. The CFUs of B. thuringiensis were counted and recorded for each culture plate.
Trade/Device Name: Airocide TiO2, Regulation Number: 880.6500, Regulatory Class : II, Product Code: FRA, Dated November 18, 2003.
Tests were conducted in August of 2002 with analyses conducted in August and September. The effluent from the Airocide device was sampled and analyzed to determine gas species and concentrations. Ozone was found to be below detectable levels and the volitile organic compounds were found to be very low in the ppb (parts ber billion range).
Whole cells deposited on a titanium dioxide-coated surface have been oxidized in air to carbon dioxide via photocatalysis. This paper provides the first evidence that the organic matter in whole cells can be completely oxidized.
A study was performed examining the airborne microbial killing efficiency of the Airocide® bioconversion system. The study was conducted in coordination with the medical microbiology & immunology and biomedical engineering departments of a major state university and examined baseline bacterial and fungal cultures, commonly known as pathogens, collected at specific clinical test areas. Samples of unique clinical interest such as methicillin resistant Staphylococcus aureus (MRSA) were studied in depth. Results of the test showed bacteria reductions of 69% in an Ear, Nose & Throat (ENT) Day Surgery procedure room, 25% in a Surgical Operating Room (OR) and 95% in a Surgical Instrument Sterile Preparation Room. MRSA was present in the OR and reduced by 100% after use of the Airocide system.
A clinical test of the Airocide® bioconversion system was conducted in a pediatrician's office complex. The primary objective of the test was to determine the effect on airborne bacteria of turning off an Airocide system that had been operating 24/7 for 6 months inside a pediatric facility. The secondary objective was to measure the difference in performance of the Airocide system in a pediatric "sick" waiting room compared to a pediatric "well" waiting room. In 24 hours after turning off the Airocide system the airborne bacteria in the facility increased by an average of 181%. One week later the average level of airborne bacteria was 211% higher than when the Airocide system was operating.
A study measured the efficacy of the Airocide air bioconversion system in removing airborne bacterial colony forming units (CFUs) in an operating room in an outpatient cosmetic surgery facility. Two tests were run in the 1,750 f3 operating room. In test #1 there was a 93% reduction in airborne bacteria in the operating room after 24 hours of operation. In test #2 there was a 47% reduction in airborne bacteria in the operating room after one hour of operation.
Tests were performed in multiple locations inside the offices of a 26,800 ft3 dental practice to measure the efficacy of two (2) Airocide systems (model ACS-100) in removing airborne bacterial and mold/fungal colony forming units (CFUs). The tests resulted in an average 45.3% reduction in airborne bacteria in 24 hours and an average 80% reduction in airborne mold/fungi in the same 24-hour period.
Air sampling tests were performed in an active oral surgery and periodontal medicine facility to measure the efficacy of the Airocide bioconversion system in removing airborne bacterial colony forming units (CFUs). The tests resulted in airborne mold/fungi reduction of 66% in the operating room (OR#3) and 100% in the adjacent corridor in 48 hours. Airborne bacteria were reduced by 82% in the corridor in the same 48 hours.
ABSTRACT. An onsite study determined changes in the colony forming unit (CFU) count of airborne bacteria and fungi/mold in two waiting rooms of a primary care pediatric office as a result of using an Airocide bioconversion system. The data supports the hypothesis that levels of airborne bacteria and mold/fungi begin to increase when the Airocide system is turned off after continuous operation for a given period of time.
The authors provide a research study examining the airborne microbial killing efficiency of the Airocide Air Quality-Improvement System (Airocide bioconversion system), a unique photo-catalytic reactor. The study examines baseline bacterial and fungal cultures, commonly known as pathogens, collected at specific clinical test areas.
