Alen A350 and A375UV Ultra HEPA Air Purifiers


Alen Air Purifiers. Alen A350 HEPA air purifiers and Alen A375UV Ultra HEPA air purifiers improve indoor air quality. Good value air cleaners with lifetime warranty. Expert reviews, customer reviews.

The Alen A350 and A375UV air purifiers offer complete air filtration removing allergens like dust and pet dander as well as common household odors and gases. During our testing both models removed over 90% of the particles in the air on the first...

Not our quietest air purifiers: The noise level on the Alen A350 and A357UV air purifiers is not unreasonable but it also is not whisper quiet. The first two speeds are relatively quiet and speed 3's quietness is subjective depending on your noise...

The Alen A350 and A375UV air purifiers use the same filters and do a very good job at removing allergens and light household odors. The main difference between the two models is the amount of technology they include. The A350 is the less expensive...

"I have purchased other air purifiers before and wasn't happy with the results - this time I researched and read a lot of reviews on a variety of sites. All things pointed to the Alen A350. My family could immediately tell a difference in how we felt....

Couldn't be Happier with Purchase


I purchased this air filter over the summer with my stimulus check from the good ole government. I had wanted a room air filter for my bedroom for a long time. In the spring I have seasonal allergies to contend with and in the winter dust makes me...

Good air purifier


My children have asthma and I bought this air purifier for their bedroom. It definitely didn't help their asthma overnight, but with continued use it has made a difference. At the lowest setting, it is very quiet. We put it on the second setting at...

It actually works, but for a smaller space


I have bad allergies, and my Oreck air purifier was not working at all. After my research I found the Alen 350 and decided to give it a try in my 150 sq ft bedroom.

Filter replacement was 10 months, not 4 It works

Not sufficient for larger rooms unless left on the loudest setting

So far pretty happy with product


We run it on the lowest fan setting which is very quiet, but does not move a lot of air. The next speed up of the fan is loud. It would be nice if the product had a setting that was above the lowest setting, but not as much as current. The step up in...

Attractive Design, Quiet

Expensive, Variation of Fan Speed

Couldn't be happier!


After doing a good deal of research, I purchased the A350 for our 1 bedroom apartment in NYC primarily for the dust. We've only had it for two weeks, but I couldn't be happier. The setup it very easy, it runs very quiet (we keep it on speed 2 while...

Quiet, gets rid of dust, does a great job all around

Highest level is pretty loud
