Allen air purifiers provide clean, clear air quietly. Love my Alen 350 air purifiers. The air is cleaned of airborne particles and my house has less dust! Vacuuming the prefilter (just under the cover), once a month, is sure proof of how much dust and particulates are in the air. Thank you for providing an air filter to make my home environment healthier!

Best purchase in a very long time! The air purifiers I purchased from Alen are amazing. I can finally breathe again at night. No more making funny noises with my throat or hearing my husband snore. I never would have believed the air purifiers would have made such a big difference in the quality of the air we breathe. We purchased a large unit Breathe Right for the family room and run it every time we open the woodstove to add wood and occasionally during the day. The small tower unit, we run while we sleep. I would recommend these purifiers to anyone who would like to breathe clean, fresh air.

Excellent product, especially for allergy sufferers I have bought 2 air purifiers over the past 7 years. I am able to control my allergies better with the air purifiers and have reduced how many sinus infections I have had over the years. I love the auto-ship feature with the filters. I know I'll get a new filter on a regular basis and I don't have to worry about ordering it myself.

Alen - Outstanding Purifiers and Company! We purchased a unit directly from Alen Corp about 5 years ago. The unit had an issue with the fan speed. Alen Corp simply had us send a photo of the unit and a cut cord. A replacement is being shipped out asap. We have loved and used our until almost daily since its purchase! Love these purifiers and Alen customer service is outstanding!!!

I haven’t even plugged the product in… I haven’t even plugged the product in yet, but I had to review the company right away. So far, this experience has been phenomenal! I haven’t had customer service like this in quite some time! I received multiple emails keeping me updated on the progress. It even arrived sooner than I expected. I appreciate their dedication to an excellent customer experience.
