Bought one of these for my stupid smoker neighbor. Wasn't expecting much but was shocked how well it works so I bought a few more for musty areas

Bought it to plug at the door when my husband smokes in the corridor. I was so surprised at how well it worked! The smell doesnt come in anymore

I smoke at home when no one is around but the smell used to stay for hours. Bought it just to try out and within 20 mins all the smell is gone.

Really crazy how fast it works.
