The best air purifier is a $20 Lasco box fan with a 3M square furnace filter duct taped to it.
You can vary the cost and filtration ability based on the filter. A super duper filter is like $35, and a midrange is about $20.
Step it up to a comparetto.

I've got this setup to deal with cat litter dust. It works very well for that purpose and the filters are cheap (I get the cheapest one that's not see-through, <$10CAD I think).
That said, it's very loud even at the lowest setting. It's not something you want to share a room with. I use my home automation stuff to only run it when required, based on a motion detector at the litter boxes.
Box fan is too loud even on the lowest settings, good when the air quality is horrible but not for general use, imho.
