Let's talk in general terms first. HEPA bests non-HEPA by miles. Make sure it's got a HEPA action. The other thing is replacment filters. I have had many air purifiers now. Some have washable filters and some have expensive replacable filters. I think the washable ones are not HEPA. I have had a lot of kinds but the best I ever had is round, and the filters look like an old style air filter for a car. This is the one my allergist uses too. It's rated for multiple rooms, and really does the job in her office with 8 treatment rooms, and has a carbon filter too which really works for odors. I have one like this made by Honeywell, but I believe there are several maker that make this style. I am not endorsing Honeywell, just the style of filter. They are rated by how many feet they cover. It looks like this picture, and this one you never replace the folter, just cvacuum it! How cool! : http://www.achooallergy.com/honeywellenviracaire.asp#Product_Reviews

If you ever HAD to replace the filter, it's only 22.

Good luck finding what you want. I think the way to go is to figure out what style you want, then shop for price.
