Thanks Germ Guardian
I’ve been using this for just under a week, but it only took 24 hours to notice a huge change in how the air smelled.  I have it in my bathroom, and the air smells clear, no odor.  I don’t have a bathroom fan so it always smelled like musty/wet dog from the shower and towels.  But since using the Germ Guardian, huge difference!!  So much so that I’m planning to buy a couple more for my smaller rooms!!  It fits nicely into the outlet, a small blue light shows the UV working.  The sound I attribute to a small fan, I’m not bothered by it, but multiple reviews I previously mentioned were irritated by it.  It circulates and sanitizes air, it’s going to make some noise—I hardly notice it.  Highly recommend.
