It works great for a small area
It works great for a small area. There is a definite difference in the way the room smells. I did a simple test of putting some smelly garbage in a closed spare room and let the garbage sit for a full day. Afterwards I plugged in the unit, and within three hours the garbage smell was gone. Those that have mentioned it does not work and is a waste of time, may have had it in a much larger room, that would take longer to clean the air. Also when new odors are introduced, you have to take that into account as to how much longer it will take to clean the air. My only wish is that it were bigger to cover a larger area, instead of having to buy multiple to place in the same room.
