Alen A350 HEPA Air Purifier

Product Review

Product Features Effective removal of 97.5% of all particles less than 3 microns such as pollen, dust, animal dander, dust mites and molds All-in-one pre-filter/HEPA filter/light carbon filter that makes filter changing easy 4 speed settings & 12-hour timer Wall-mountable, space-saving design Built-in ionizer that minimizes pollutants without producing ozone Product Description Talk about the Goliath of air purifiers, the A350 has the power to clean air in rooms up to 800 square feet! As the leader of strength, it deserves a more regal place to sit than by a couch or chair so Alen made the A350 wall-mountable. Not only does it save space, but it can quietly disperse clean air over its domain. The A350 comes with an ionizer that charges dust and pollen particles which has been shown in university testing to produce a benefit for many who suffer from respiratory allergies. Unlike other ionizers, though, the A350 does not produce ozone, making it the ideal alternative to common air cleaners. With this much power and versatility, why Wouldn't you want one?

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...Read more

Must buy for allergy sufferers., May 22, 2009

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.
