Good unit, carfull when you travel.
My husband has lung problems and I only clean with vinegar (it may smell for a short time but it does not hurt his lungs like chemicals do).  Traveling with him is a challenge since most hotels use very harsh chemicals to clean.  This is very helpful to eliminate alot of the irritants.  We check in, plug it into the wall and leave to do some sight seeing; by the time we return he can be in the room without difficulty.  But be careful because it does not do well if you drop it (my fault I had to replace it).<br /><br />It also gets rid of the dog smell (he likes to lay on our bed and pass gas) that accumulates in our room.
