CANADA: EffectiV HVAC’s new Play-UV diffuser is said to have been third-party-tested to be effective in containing the spread of Covid-19.
Typically installed in the ceiling and designed to treat air before it enters the room, EffectiV HVAC’s UV diffusers combine low pressure drop MERV-9 filtration and UV-C germicidal irradiation, with high induction diffusers improving air mixing.
The tests were conducted by full-service reference and bioanalytical laboratory, Innovative Bioanalysis, in its laboratory in California. Using a live sample of SARS-CoV-2 in a triple redundancy test with control points, the results showed EffectiV HVAC’s UV diffusers have a 99.949% single pass virus neutralisation rate while supplying 458ft3/min of air.
The UV diffusers are also said to be effective against other airborne viruses and bacteria, like tuberculosis, legionella and influenza.
EffectiV HVAC’s UV diffusers neutralise the virus at the entrance of each room to prevent between-room transmission, while better air diffusion can help reducing in-room transmission.
The UV rays are contained within the diffuser for occupants’ safety. Made of quartz, the UV diffusers do not emit any ozone.
