Larger HEPA air purifier?

Do they make a HEPA air purifier that can filter a room larger than 20' x 23'? Anyone know of any??

I bought an air purifier for my room off there. It's only 350 square feet, but works great. They've got all sorts of products. I assume one that had that capactiy would be pretty expensive.

Oh yeah, if you buy through FatWallet.com, you can earn cash back (I think 5% or something like that.)

ETA: Here is a comparison chart I found:
