Title: Watch Out For Hidden Costs
Review: The Alen A375 UV Air Purifier is the same as the Alen 350 except adds UV light for germs and Bacteria.I own the following:An Alen A350 = $349 (3 stages, 400-800 sq. ft)Alen A350 Air PurifierAlen A375 = $599 (4 stages, 400-800 sq.ft)Alen A375 UV Ultra HEPA Air PurifierAlive Air Purifier = $319 (9 stages, 865 sq. ft.)Alive Air PurifierPro's1) Has 4 technologies - HEPA, Carbon, Prefilter, UV2) Runs quiet on lowCon's:1)You have to buy 2 HEPA filters on auto-ship to maintain the "lifetime warranty" (which will cost $128 a year - even if you don't need it). So the lifetime warranty makes them money.2) The replacement filters are rather expensive.3) It seems like a lot of money to go from $349 to $599 just by adding a few UV bulbs.It does what it says, and I'm glad Alen upgraded the 350 to add UV, however the cost is over the top for this small air purifier.
