This review is from: Alen Air A350 Purifier (Kitchen)

My wife requested that we purchase this air filter to reduce allergens and dust in our (partially-built) home's air. I was skeptical about the unit due to the cost and several reviews (at various vendors) citing noise and poor fan bearing performance; appealing to me was the size, shape, and ability to wall-mount it. So, with a little goading from her, we decided to accept the risk and try it out.

It is an impressive little unit! We run it on setting 2, which moves quite a bit of air in near-silence, when we are home. Settings 3 and 4 are fairly loud, but I think that is unavoidable given the massive amount of airflow these settings generate versus the size of the unit. The unit is now in constant use (again, almost exclusively at setting 2 with the ionizer active) for over three weeks without any change in performance, so I expect we will not have any problems with it in the short run. The room in which it is located is 650 sq ft. Dust reduction is substantial, but I will wait longer before determining just how well it works in that regard.

ADDENDUM AS OF 6/24/2010:

Six months have passed and the unit continues to work flawlessly. Dust accumulation in the house is reduced by half, at least. I have to clean the pre-filter about once a month, but it separates from the HEPA portion easily and can be hand washed or cleaned with compressed air. I suspect I was over-estimating the quietness of setting 2, but I still think it is fairly quiet (not much louder than my computer fans). My wife loves silence and will often turn it off if she decides to take a nap on the couch that is located nearby.

ADDENDUM AS OF 11/3/2011:

Still going strong! I recently replaced the HEPA filter on it for the second time (so, this is the third filter being used), and it remains quiet and reliable. Again, clean out that pre-filter regularly! If you do so, I doubt you will find it necessary to replace the HEPA filter any more often than I have.

I suffer from seasonal allergies. We put this unit in our bedroom and switch it on low speed (you hardly know it is running) for about three hours when retiring. I am experiencing an amazing improvement in sleep quality because my breathing is improved and I don't wake up sneezing every few hours. I highly recommend this model for people with allergies.

It might be very powerful but very noisy. I could not stand it so I returned it to vendor.
