We have seen a difference
I bought one of these to deodorize it because for some reason it always stunk, shortly after he moved buildings and I brought it home. I plugged it in by my chair and did not think anything of it. I used to catch everything that came down the pike and it was not until Covid arrived on the scene and I saw an ad for another one, that I realized I had not been sick in some while, as a matter of fact I had not been sick since I brought it home and realized that had been over a year ago, so I bought this one without hesitation and consider it a great return on investment. If our camp ever opens up I am buying one for the trailer also!
