so good i liked -

Top notch product and service Our Alen Air Purifier suddenly stopped working after an electrical power surge. We called the company and a tech had us try several things to start it again. Nothing helped. He asked how long we had had it and we thought 5 years. He looked us up in their system and discovered it was 8 years old. After checking our information he told up to expect a replacement, after Independence Day. Amazingly it arrived today, less than a week from calling. Please understand this was still covered under the warranty, that the technician was extremely helpful and concerned and we have always been delighted with the unit's preformance. I highly recommend this company and their product.

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.

Creates clean, sweet smelling fresh air. We love our new Alencorp air purifier. I am no longer suffering allergy symptoms from indoor particulates created from our wood stove , or by our sweet dog. The air is fresh & clean and we are all much healthier & happier having purchased our Alen and running it daily. Thank you!

I have been dealing with this company for over two years and have been extremely satisfied with products and service I purchased two purifiers from Alen and have really noticed the difference in the air quality in our home. The automatic order system is fantastic and always arrives on time. When I had a question about changing out the UV light they were extremely helpful and called me back right away. I always recommend this product to friends and family that come into our home and comment how clean and fresh the air is.
