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).
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.
Employing the most technologically advanced bio-aerosol laboratory methods, combined with modern pathogen surrogates, the S400 delivers efficacious laboratory tested kill rate for these and many more common pathogens.
Bio-aerosol laboratory full room size chamber disinfection device study, testing for efficacy in airborne pathogen killing rates in real-world conditions.
Tested in OR’s, ER’s, Waiting Rooms, Patient Rooms, Physical Therapy Rooms, Recovery Rooms, EVS Service Laundry Rooms, case studies conducted at 2 major Medical Centers, resulting in 50% – 70% non-viable particulate reductions in the 0.3 to 10 micron particulate range.
Four bacterial pathogens were tested to validate efficacy. A clear trend was observed in the elimination of airborne bacteria from the test chamber. The following report summarizes the lab’s findings
A Florida hospital compounding pharmacy used the S400 to pass requirements for USP797 – CAG-009 in September 2018.
Chemotherapy and ante rooms in the hospital were out of compliance prior to the introduction of The S400 air device.
A case study conducted at a Major NY Medical Center proves reductions in the 0.3 to 10 micron particulate range when a S400 was in a typical patient room. Tests including HVAC, Central Air Handler Units, with 95% filtration attachments, and base line coil tests were performed. Particulate reductions consistent despite HVAC inconsistency
Microchem Laboratory aerosol testing chamber determines the effect of air disinfection devices agents on microorganisms present in the air, as bioaerosols.
The NPAC , Negative Pressure Aerosol Chamber, measures 10′ x 10′ x 8′ (800 cubic ft.), which is considered the standard room size. Tests conducted in the NPAC simulates real world conditions of whole room disinfection devices against aerosolized bacteria, fungi, and viruses.
