Absolutely Amazing!
These air sanitizers really and truly work.  I have severe asthma and allergies and recently found a leak in our water pipes.  By the time we discovered it, mold and mildew were causing my asthma and allergies horrible problems.  Pipes can get repaired, but finding all the little nooks and crannies of mold and mildew was next to impossible.  I plugged in these air sanitizers into both rooms of the basement (where the leak was) and with 24 hours or so...I could handle not only being in the room but I also had NO issues with breathing.  They are completely amazing.  I have 3 now and have one in each room.
