Alen A375 UV Ultra HEPA Air Purifier

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...Read more

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.
