Tests were performed in multiple locations inside the offices of a dental practice to measure the efficacy of the AiroCide system in removing airborne bacterial and mold/fungal colony forming units (CFU’s). The tests resulted in an average 45.3% reduction in airborne bacteria in 24 hrs. and an average 80% reduction in airborne mold/fungi in the same 24 hours period. 

Duplicate tests were performed in an operating room of an out-patient surgery facility to measure the efficacy of the AiroCide photocatalytic air purifying system in removing airborne bacterial colony forming units (CFU's). The test resulted in a 92% reduction in 24 hrs. and a 47% reduction in one (1) hour. 

Clinical engineers and biomedical technicians play a vital role in bioterror preparedness because of their extensive expertise regarding new technology assessment. This article details a new technology for maintaining healthy indoor air quality in the event of a bioterror attack. 
The study examines 2 outcomes: (1) examination of a reduction of airborne microbial counts in specific clinical areas as a results of implementing the PCR unit in the clinical areas sampled (as identified in Tables 1-7) and (2) statistical evidence related to the cost-related savings due to lessened risk factors of lower microbial counts involving nosocomial and cross-infections. Healthcare economics and patient comfort will be impacted as a result, if lower airborne microbial colonies result from the implementation of the PCR biocide unit. A scientific explanation of the photocatalytic oxidation (PCO) process and the distinct uniqueness of the PCO and ultraviolet (UV) combination process (PCO) utilized by the PCR biocide unit will be examined in depth. 

A clinical study was conducted to determine the initial and sustained reduction of airborne mold and bacteria in two residences of similar size, design and structure.
Airborne mold was reduced in the homes by an average of 60% in 24 hours and even further to an average of 87% in 6 months. Bacteria in the air inside the homes was reduced an average of 57% in 24 hours and maintained a level of 49% lower than baseline in 6 months.
