I was skeptical, but it works!
I bought this expecting the worst and hoping for the best. We keep the trash in our walk-in pantry which usually reeks from whatever food we have tossed out. It’s so gross that I typically try not to inhale when I go in (gross I know, but we do everything we can to limit the smell including over changing the trash). The morning after plugging this in I definitely noticed a decrease in odor and overall crispness in the air. I actually over sniff  now when I go in the pantry because I’m curious how effective this thing is - so far I’m sold!! Granted the pantry is small so I wouldn’t expect the same results with a large room. Worth a try for sure!
