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!!!

Two BreatheSmart units are definetly removing a lot of the dust from our house. I have two BreatheSmart units that seem to be working very well. We have an unusually high volume of dust in our house. The source is probably our coal burner. We have used a coal burner for 25 years without this problem. So we can't be sure of the dust source. I will say the BreatheSmart units have helped a lot, but they have not removed 100% of the dust. We get a noticeable amount of dust every two or three days on the furniture. Before the BreatheSmart units were installed we could notice a lot of new dust on the furniture everyday. My next move is to shut down the coal burner to see what happens. One of the units is noticeably noisier than the other when they are both running at the same speed. It seems like there is some internal vibration with the noisy unit.

so good i liked -

Outstanding Product We have one of the Alen room air purifiers (T300) for a couple of years now and it works as advertised. We receive our air filters every six months and are very satisfied with their service. This year at Christmas time they even reduced the cost of their filters which made it even better. Amazing product with great service!
