We have two Alen air purifiers and both are running nicely. One is extremely quiet on low speed and the other makes a low hum noise which is sometimes annoying.

I have the 2 units for about 3 months now yet I still have to feel the effect. So far my bronchal asthma is still the same as before I purchased these Airfilters.

We were very happy with the service, and the time it took to arrive at our house after the order was made. The price is a little high, but the machine does a good job in our home.

I have the Alen air purifier and have been pleased with its trouble-free operation. I am in an older condo in Chicago and do think the air purifier makes a difference in the air quality in my apartment. I am also impressed with the efficiency and courtesy of the Alen Corp. staff.

Your Alen Air Purifier is excellent. It has made a big difference in how I sleep in my bedroom now. I have been a huge allergy sufferer for most of my life and this has really improved my sleep. My husband who does not typically have seasonal allergies, says he notices a difference with the quality of his sleep too.

I am so pleased with this purifier and the relacement filters. I signed up for the replacement filters to be sent automatically. It keeps me from forgetting. They are always prompt.So happy with the service. My research paid off for me.
