OH YEAH!! My daughter has awful allergies and we have tried everything. The BEST thing so far has been an ionization unit from Eco Quest. It uses the same technology used to clean up after 9/11.
She has improved so much since we got ours that she is off one of her (steroid) medicines! YAY!
It def. eliminates all odors too, the only down side to that is when I want to burn a smelly candle, but it is worth that one little sacrifice!! I can't say enough good things about it.
It also killed mold on the baseboard of our living room.
Here is where we got ours from:

By the way, we don't get anything at all for telling you about it -we are just happy customers!
