Wish I had bought 4
I bought this when we were planning a family vacation and would be staying in hotels, etc. I know that every time you go on vacation and stay in a hotel someone gets sick. This didn't happen, to us. In fact on our last night, we had to overnight in a hotel before going to the airport the next morning. On arrival at the hotel the room STANK  but after a day of driving, we were too tired to change rooms. We took this out and plugged it in, went to the pool for an hour and came back. Not a smell was there.<br /><br />Returning home I have given to hubby to put in his office which has that stale nasty unclean smell. This has made a great difference. I would definatley reccomend and repurchase.
