After owning a 45i for a year and being completely delighted with it, I decided to move it to the bedroom and get the larger 75i for our main living area. Again - really happy with this purchase. It filters a lot of air, is quiet and pleasant, and as attractive an air purifier as you’ll find.
We have a carriage home with high ceilings. I wanted to get a purifier to cover the largest square footage possible. The quality of the 75i and its ability to clean the air in our home meets every expectation we’ve had! Very pleased and satisfied!
My kitchen cupboards were to be stained walnut and sprayed with four coats of lacquer. I was looking for an air purifier and ordered an Alen. It was delivered quickly and saved my lungs. I am almost 84 years and have asthma. The Alen worked so well and did such a good job that I am happy to tell you what a wonderful air purifier it is.
This air purifier has worked wonderfully in our home. It's much bigger than I expected but looks good and keeps the air circulating and healthy in our entire one level home. I'm happy with my purchase.
