This is the best written and illustrated brochure I have ever seen ! Way to go EPA!
Because it is a PDF file, I can't give you a direct link so........
go first to nlquery.epa.gov
do a search there for UV light and air vents
What you want is this.........
This is a really clear article(with diagrams) and factual, scientifically researched information.
One funny statement said "Blame Canada!" It meant we get our cold , dry air from Canada and low humidity is why flu viruses live longer in the winter! Sorry to all Canadians!
I just had our air ducts cleaned and the company wanted to put in a UV light to kill molds , etc. in the system. I did not have them install it. $400. I did not know if it really worked. So I went poking around the internet.
Maybe next time we clean the air ducts I will have them put in the UV light..........maybe!
