Third-Party Verification of AIr Disinfection Efficacy Claims
Even though air cleaning devices don’t have to be registered, the EPA does have guidelines for the appropriate type and size of bio-aerosol chamber in which to test. Scientific Air Management products are tested under these guidelines and have Laboratory tested kill rate of up to 99.9995% of airborne norovirus surrogate (one of the most difficult viruses to kill) and 99.9999% of bacterial surrogate including TB and C-diff representative pathogens.
Two independent, nationally recognized lab facilities (Environmental Diagnostics Laboratory and MicroChem Laboratory), using these guideline conditions, performed efficacy testing of airborne pathogen. The following are the tests results and compiled reports.
Per suggested guidelines, Scientific Air Management adhered to the following test protocols:
Test methods employed
Contact time (minutes vs. hours)
Type of pathogen
Killing percentage (minimum 99.9%)
Air Disinfection Field Studies
The conditions above are difficult to apply in field studies and are hard to accomplish in hospital settings.
For field studies to achieve the same efficiency in testing parameters, they should be conducted at unbiased facilities with the same scientific test conditions that eliminate all testing room variables, like:
Variable source contamination
Personnel and visitor traffic
Equipment movement
Open doors
HVAC inefficiencies
Concise testing should only include the pathogens being tested and the air management device itself within a standard size room.
The field study below, Pharmacy Compounding, is the closest on-site testing to match laboratory conditions. Due to the nature of the sealed and closely regulated pharmacy Anteroom and ChemoRoom, laboratory-like conditions were achieved as the tests were performed in these areas.
