evronAir Ionizers for Home,Negative Ion Plug In Folding Prongs Mobile Ionizer with Output up to 20 Million Negative Ions/Sec (Blue light 1 Pack)

I have this in my small sized bathroom. It does seem to help some. We have a slight mold smell problem because the faucet to the toilet had a bit of a leak and went unnoticed for a while. It isn’t very powerful, but it does seems to put out negative ions (according to the smell.) It’s very compact. It has a blue light (wish it were red for sleeping to use in the bedroom, but it’s not super bright) to show its working. I certainly wouldn’t pay the $30 that they’re asking at this time. But since it had the 50% off coupon it was a decent purchase.
