They work - I bought one…
Oddly enough whatever they do I’m allergic too because I sneeze like crazy after my stuff has been in on.
Tell you what - I have a Scent killer that I now don’t use…. I can ship the unit seperate from the big arse container so I’m going to put it up for sale for $75 bucks shipped…. All one would have to do is get a big storage container, and cut a hole in for the tube.
BTW - don’t put anything with elastic in it in the thing, it will lose it’s stretchiness.
