Honeywell. There were recommended by my allergist. I still have one that I bought over 10 years ago. They have good strong motors and move a lot of air. Noisy, but we like them that way. White noise helps us sleep! They don't seem to make my models anymore, but its closest to this model. http://www.target.com/p/honeywell-true-hepa-allergen-remover-air-purifier/-/A-10592056#prodSlot=medium_1_21

no tips, but I think we need one as well. I have a big mold issue, and fall is horrible for me (ironic, because it's my favorite season). I tried to use the hepa furnace filters but my apt says they won't work in my furnace. I saw the charcoal filters and was interested in that, but I don't know anyone who has used them.
