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.

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.

so good i liked -

Bought two and were delivered earlier than I expected. One was for me the other was for my son. The unit is very quiet at low speed, I have to put my hand at the exhaust end to determine if it still working. I rank the product 4 stars because it is very hard to removed the face cover to check if the filter needs replacing. The instruction stated to raise the face plate up, but it will not budge (my son had to force it by pull it up front instead). Because of this issue I am reluctant to check the filter's status because I might break something. (So I plan to do check after 3 months or more given a 24/7 use).

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.
