input:  Now, answer this question: Title: WHY? The air does stink when using this model. Review: Why would they make it this way? It doesn't make any sense at all. I don't understand how this air purifier can cause the air to smell after using it but it does. At first I thought it might just be one bad unit. Since I have two I swapped one out for the other. In a 12 by 12 room with the door closed it starts to smell within 30 minutes. After an hour or two the smell is strong. It is an odd smell and I find it unpleasant. The only solution is to leave a door or window to the room open so fresh air can get in - wait doesn't that defeat the purpose of the dang thing? :o)Silly Hunter, why in the world would you make an air purifier which makes the air smell. It doesn't seem to make any sense whatsoever. If I could, I would attach an air sample so you experience what it smells like.As long as you don't mind having a bad smelling room, it works as it is supposed to.Save yourself the annoyance and buy something else.
