Excellent product, works very well with tobacco smoke and cooking odors. Just set it to automatic, it is silent most of the time but will automatically adjust if it detects smoke or odor. Worth the money.

I have been looking at and searching for a decent air purifying unit for at least 3 years, I find the cost runs way to high and the looks of the unit definitely wasn't designed by anyone with designing taste! And even though the germicidal UV light should be completely hidden from view most of the air filtering UV units I have looked at had obvious glowing of the eye damaging UV lighting.
Now for my review of this item,

The looks-acceptable.
Noise level-acceptable on low speed during sleeping.
Controls and adjusting-My wife has no problems working it! (Now that says a lot!)
The Glowing of the UV lights-Almost literally impossible to see!
Does it work?-my wife thinks Claritin cured her of her allergies. It took about 6 to 8 weeks letting it run 24-7 but it will clean up the impurities in the house and before you know it your not sneezing! Well it worked for me wife.
Would I buy another unit-Yes if needed.
The cost- acceptable
My only problem with it is "How would I know if one of the UV germicidal lights go out?"
I'm the type of person that probably never give out 5 stars to nothing, but I will give out 9.5 out of a 10 point scale for this item.

OK, so it costs a lot of money. They say you should replace the HEPA/Carbon A375 UV filter every 6 months (for $49 each). That's a bit excessive. However, the filter is pretty quiet at high speed (which I leave it on all day and all night long because my dust/dust mite allergies are THE WORST). I have one in my bedroom and one in my living room that run constantly on high speed. I have no idea whether the UV lights do anything or not, but I will try anything to help reduce my allergies. It is easy on the eyes and has a nice display, and it doesn't take up too much room. I also did research when I bought these (about 7 months ago) and they scored highly in air filter tests. If they were less expensive, I would definitely recommend them.

Not what I've expected for almost $500. I got it three days ago. It produces ozone smell. On auto mode it can wake you up in the middle of the night because it suddently decides to go full speed. It's not programmable, so you cannot set it up to be turned on two hours before bed time for example like my other ones. Instructions are incomplete and difficult to match with the buttons on the purifier. If the smell doesn't go away, the purifier goes back. I have two other different brand purifiers, I have to admit that they are nosier, but don't smell.

We bought this filter for our new apartment after several weeks of feeling terrible (congestion, puffy watery eyes, feeling tired, coughing, etc.) because we knew there was some sort of non-hazardous mold and dust combo at the root of it. This puppy looked like it'd do the trick, and for 6 days, we felt awesome. It worked very well! But on day seven the rotator inside this thing literally fell off the axle and ceased to work any longer. We were unable to fix it ourselves, and we found that once we opened up the packaging, we owned it. No returns were permitted, but we were allowed to pay for S+H back to the manufacturer for them to fix it. [...] The problem I have with this item is that the price is six times our cheap filters', and Alen's ghetto manufacturer hotline and inability to provide us with a new, working filter, indicates it shouldn't be worth this much.

UPDATE: Alan (the manufacturer) never called us back after we left 5 messages. We threw our $600 filter into landfil.

Having used this filter for a year, which I frankly think should be a requirement for most reviews, I can recommend this filter without reservation. It's extremely quiet at the lowest speed setting, quieter than any other filter I've used. Equally as important, even at the highest settings, the QUALITY of the white noise produced is very clean - no buzzing, whining or humming - just clean white noise. The quality of the filtration seems to be consistent with the professional test results - class leading. This is an excellent product.

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 Purifier
Alen A375 = $599 (4 stages, 400-800 sq.ft) Alen A375 UV Ultra HEPA Air Purifier
Alive Air Purifier = $319 (9 stages, 865 sq. ft.) Alive Air Purifier

Pro's
1) Has 4 technologies - HEPA, Carbon, Prefilter, UV
2) Runs quiet on low

Con'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.

This is a great filter. We got it for our baby daughters room when she was having some problems. She's been good since. We put the filter in a room that we had been operating a Sharper Image model they pimp on TV commercials and the Alen immediately kicked on high and showed particulate on its indicator....even though the other filter had been on continuously (highest setting) and properly maintained.

Another reviewer complained about the noise on auto...just leave it on setting 2 and it should be good from there. I have allergies that I get shots for (now) and have had no problem leaving it on this low of a setting.

works great - had none of the problems others have voiced - ordered a 375 after good results from a 350 because it has a couple more features which I have found useful since i recieved it

Do recommend to anyone who want to have a portable air purifier. It is easy to operate and use. It really work great for a smaller space. We love it.
