uv light and air filtration?
I'm building a house, and I've decided which equipment and contractor I'm going to use. I'm using spray foam with a non-vented attic and i'll require 2 seperate units(3 ton and 2 ton). I've been told about and read about the systems with uv lights. I asked my hvac contractor and he said it would be good to have but not a necessity. It would cost me about $1500 more for each unit. Does anybody know anything about these systems? I'm going to have to check, but I think he told me he uses the whole house air purification (has both the air filter and uv light) made by ultravation. thanks
