The Rainbow air purifier is an ozone based purifier which will eliminate mold, smoke, and odors. For mold I haven't seen anything better. But if you have allergies or asthma I wouldn't recommend this model. Ozone does little, or nothing, for pollen or dust by itself. Rainbow Air Purifiers are very similar to Ecoquest Ozone air purifiers except for appearance and construction. Of course the price is also half or more of the Ecoquest brand, probably because the Ecoquest is an MLM product.
Ozone will remove offensive odors caused by tobacco, smoke, urine, pets, mildew, diapers, formaldehyde and other chemical fumes. You might have to replace the ozone plates every 4-9 months. The cost is $50.
The dangers of Ozone to the lungs, and how ozone works, is covered in the video below. If used properly for treating the air (not for everyday use) ozone can be useful, but does nothing for dust and pollen removal.

If mold, smoke or odor is a big problem then this durable model would fit the bill. For a good general, everyday use air purifier in your home this would not be the one to get. If you have allergies or asthma, I'd run for the hills because of the ozone problem. Better yet look over the comparison chart via the link below.
