Laboratory Testing
Extensive laboratory and field testing demonstrate strong odour and air hygiene performance, and confirm AIRsteril systems are suitable for continuous use in occupied areas.
AIRsteril products have been evaluated by a variety of reputable laboratories in the UK and internationally. Testing has focused on performance against airborne microorganisms, odour causing compounds and, in some studies, microorganisms on test surfaces. Independent field trials have also demonstrated reductions in airborne contamination and noticeable improvements in odour conditions under normal operating use.
Across these studies, laboratories have reported clear reductions in overall bio aerosols and airborne microbial levels, including reductions in total viable count (TVC) and colony forming units (CFU). Additional testing using a range of representative bacteria, viruses, moulds and fungi has demonstrated performance against some of the most commonly referenced organisms in indoor environments.
Detailed relevant test data available upon request.
TVC/CFU – over 99% reduction after 4 hours, up to 99.77% after 12 hours;
Listeria – decrease to 0 log cfu/cm2 within 24 hours, beyond detectable levels by day 3 (Listeria monocytogenes and Listeria innocua)
E. coli – airborne; decrease beyond detectable levels after an hour
Staphylococcus epidermis – up to 98.11% airborne reduction within 5 minutes
Staphylococcus aureus – airborne; decrease beyond detectable levels after an hour
Clostridium difficile – up to 99.6% reduction
Aspergillus Fumigatus - airborne decrease beyond detectable levels after an hour
MS-2 Coliphage - up to 92.17% airborne reduction within 5 minutes
MRSA - up to 51.81% reduction within an hour
