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.

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.

Great product, customer service needs some work After researching for months, I decided to order two Alen air cleaners in early November. I called to talk to a customer service rep because I had a special request concerning shipping. I wanted to get the filters before Thanksgiving but was unsure of when to order them because I was going to be out of town and I didn't want to miss the delivery. The rep told me I could go ahead and order and he would talk to shipping and delay the shipping of my order. Instead, my order shipped right away while I was out of town. Everything turned out fine, as a friend watching the house brought the filters in before they were stolen. The point is, I didn't need to spend 15 minutes on the phone with the rep who was not able to take of the delayed shipment as promised. The other thing I found disappointing was finding out they had a "Black Friday" sale. I could have saved $150 on my two A350s. Here's how Alen's rep could have guaranteed they'd get a 5-star review: when I call tell me I should just wait another 2 weeks and order after Thanksgiving to save money and get the shipment delivered after my out of town trip. As for the filters, they are fine. I live in the desert with lots of dust and I have dogs. The amount of dust in the house is visibly reduced and my home doesn't smell like dog. The low settings are very quiet. The highest setting is a bit noisy but that is to be expected if you expect it to move that much air around. It actually helps me at night because I sleep better with white noise. Though I don't have bad allergies I am less stuffed up than I was before I bought these air cleaners. I would recommend this company and their product to anyone, just don't expect any personalized customer service if you call instead of ordering online.

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!
