Companies that design and install UV for coil cleaning can make the claim that their UV systems kill 99% of pathogens and while, technically, that may be true, it can be misleading.
For example, for air cleaning, if you have a 22″ HVAC plenum with 2500cfm’s of air moving through it at high speeds, you have less than one second to kill the pathogens before they recirculate through your facility’s supply vents. Yes, 99% of the ones that make contact may be killed, but 99% of how many overall? You could easily be looking at a 10–20% reduction of pathogens out of 100%. This is not helpful as, quickly, you may have millions more pathogens following right behind.
With our proprietary sizing method, PetAirapy UV systems are designed for the correct amount of contact, dwell, and intensity, and are researched, tested, and study-backed to achieve a 99.9% kill rate in one air pass. See our Research & Studies page for details.
