If your company is interested in learning the extent to which its product or technology kills airborne microorganisms in real life settings like rooms, there is no better tool than NPAC and no better staff than the microbiologists at Antimicrobial Test Laboratories to help.
NPAC can be filled with high concentrations of bacteria, viruses, and fungi under various conditions. Air samples can be collected at any time during studies. Room air can be held static or recirculated. The laboratory has even developed a technique which enables surfaces within the room to be sampled remotely at intervals as tests are conducted.
At this time, clients may test their products against Staphylococcus aureus, Escherichia coli (gram-negative), Cladosporium (a mold), and MS2 bacteriophage (a virus). Testing with specific pathogens of interest may be discussed on a case-by-case basis, subject to safety considerations.
Validation studies have shown NPAC to readily generate stable concentrations of 10^7 to 10^8 (10,000,000 to 100,000,000) microorganisms per cubic meter, more than enough to verify a 3-log reduction, as suggested by EPA in its 810.2500 series guidance document for air sanitizers.
The chamber can be used to test antimicrobial devices ranging from whole room ultraviolet light disinfection systems to chemical vapor generators to air sanitizing chemical sprays. If your company is interested in conducting tests in the NPAC, call the lab to get started.
