A+++

I have four of the Alen purifiers. One 75i and three 45i's. All the functions work great and the convenience coupled with the data that the app provides are a great asset. I would definitely recommend Alen Air Products to anyone. Thank you Alen for a great product.

Replaced our Classic, it's a WINNER!

We moved our classic into another part of the house and set up the new one in its place. So far so good. The air quality seems superior to the older unit even though it was very good. We also just got the AQM and it's showing good air quality (4). Still adjusting but it's a winner!

Alen 75i

So far this seems like a good air purifier, but then I expect it to be good for the premium price. It seems to be a bit quieter than a competitor's model my daughter owns. The only minor annoyance is that on the auto setting it seems to “hunt” back and forth between speeds, especially between green and orange levels.
