Rainbow air purifiers are ozone based air purifiers that can eliminate mold and odors effectively, in fact for mold I haven't seen anything better. If these are your primary problems then this is worth a look, however ozone does not do much of anything for pollen or dust by itself. Rainbow Air Purifiers are very similar to Ecoquest (now called Vollara, called Alpine before that) except in a metal case instead of a wooden case. The price is also 1/2 or more of the Ecoquest brand, probably because the Ecoquest is sold through MLM. The dangers of Ozone to the lungs, and how ozone works, is covered in the video below.
Ozone will remove offensive odors caused by tobacco, smoke, urine, pets, mildew, diapers, formaldehyde and other chemical fumes. You might have to change the plates every 4-9 months which can set you back $50 or so as well.
