Please recommend a portable HEPA air purifier (one that does NOT produce ozone) under $100

[ereks mom]

We need one for a room that is approximately 400 sq. ft. and one for a room that is approximately 200 sq. ft.

None of Honeywell's "true HEPA" air filters produce ozone. You might check this list, then see if you can find them cheaper on amazon/ebay or locally?

I paid more than $100 for mine though. And I am not sure I have ever seen one for a 400sf room that was that cheap, not a good one.
