Hamilton Beach TrueAir HEPA Air Purifier (350 sq. ft.) with UV Germicidal Light (Model#: 04162) = $99.99 with free shipping (in stock soon)
Hamilton Beach TrueAir HEPA Air Purifier (200 sq. ft.) with UV Germicidal Light (Model#: 04160) = $84.99 with free shipping (in stock)
About the cheapest that you can find online. Other models (04161 and 04163) are also available, cheaper than other places. Those models have air quality sensor (not sure how it works though), but cost too much for my taste. I usually run them 24/7 so the automatic sensor is no use.
350 sq. ft. model (04162) sounds somewhat loud even on the quietest mode (not the worst among the other HEPAs that I tried, comparable to mid-sized fans in mid-speed). 200 sq. ft. model (04160) is much quieter but not as effective as the larger one. Only suitable for a small room.
It seems both of the models have quite good reviews by both users (check amazon) and many allergy-product sites. For example, review here.
You can't really compare these cheap ones with $500~$1000 models (Blueair, IQAir, etc.), but these do their job well. The company claims that they are true HEPA filter (99.97%) and as far as I can tell, they are better than cheap brands like Holms or Honeywell. I've tried a lot of HEPAs 'cause of my severe allergies, and never really satisfied with quality/price. This Hamilton Beach purifiers are the only models that satisfied me so far.
Operation costs are: ~$5 every 3 months (carbon filter), ~$50 a year (HEPA filter), depending on the models. It looks like all models come with 3 year warranty.
PS: By the way, yeah, Amazon carries all the models (from 04160 to 04163) and extra filters, and price is just right.
