Alen A350 Review

What the reviewers like:
In tests, the Alen A350 removes a high percentage of allergens from the air. Experts and owners like the fact that it can be wall mounted, and note the relatively low cost ($40) of its replacement filters.

What the reviewers don’t like:
The A350 isn’t quite as good at removing allergens as the top-rated (and more expensive) IQAir HealthPro (*est. $700). Some owners posting to user-review sites complain of a "humming" power supply.

Alen A350 review highlights

In tests, the Alen A350 air purifier has been shown to remove nearly as many allergens from the air as the more expensive IQAir HealthPro (*est. $700), and it’s also a little quieter. Bear in mind, though, that the Alen A350 is meant to cover a smaller area -- 400 to 800 square feet vs. the HealthPro’s specified 1,000 square feet -- and one expert recommends its use in rooms of about 250 square feet. Like the HealthPro, the Alen air purifier uses a true HEPA filter along with a pre-filter and a carbon filter for odors, and its $40 replacement filters are a lot less expensive. Overall, testers say the Alen A350 is a high-quality air purifier.

We found a good comparative review of the Alen A350 at Air-Purifiers-America.com, one of the few sources that tests air purifiers. The A350 is also included in a brief roundup by ConsumerGuide.com, receives a handful of posts from owners at sites like Epinions and Amazon.com, and is the subject of an in-depth review by the enthusiast site Air-Purifier-Power.com. It hasn't yet been tested by Consumer Reports, however.
