Alen A350 Air Purifier Two-pack (Pack of 2) Save 00

I moved into a house with a dusty a/c system and started looking for a purifier to relieve my itchy eyes and stuffy nose. I had to go to external websites to get reviews on this product... [...]. I bought the dual pack for the savings, but overall the money for product puts it in the middle price category for purifiers and it's absolutely worth it. One of my units went in the bedroom, so noise was a huge factor. All the reviews of this unit being quiet on Level 1 were spot on, I can't hear a thing when it's on 1 in the bedroom. It also had a slimmer design than the floor units, and mine mount on the wall very nicely to still allow furniture to be situated around it. Two thumbs way up.

My issue is:

- Lab tests and rating are based on level 4, which I do not use. These items should be based on level 2, and expectations should be based on that level because that is what I am reallying getting
- The square footage and effectivenesss is based on level 4 setting, which I rarely use

Note: Other reviews suggest that ALL comparable products have the same issue: they are only tolerable at lower speeds. I suggest the...Read more
