Disappointment
on February 8, 2026
Posted by: Karen H.
Are the filters suppose to get dirty? Ours ran for weeks and did not have anything deposited on the filters. Total waste of money.

Great unit. I have 2; both work well and communicate perfectly over wifi with app. Need to address directional control for vents.

Absolutely Amazing!

Not going to lie, I was skeptical at first. But in just few days after turning this beast on, I was blown away! Exceeds all my expectations. I can't even tell it is on it is so quiet. Highly recommend if you are on the fence. You won't be sorry.

A smart investment
on December 5, 2025
Posted by: Scott W.
I live in an older larger home adjacent to Little League ball diamonds in a mid sized Midwestern city, with strong westerly winds most of the time. Lots of dust! The 75i is working great and the dust inside is mostly diminished but not totally eliminated due to the high winds and sandy ball diamonds. It does a great job but it does tend to run on auto high most of the time. I take that as it is doing the job I purchased it for. My inside air is noticeably better throughout the entire house thanks to the 2 return air ducts on my air handler system circulating the clean air from my Alen. I am pleased. It was a good purchase. I recommend it.

Five years still working great

We’ve had our 75i for over 5 years now and it is still doing a great job! We have an open floor plan and keep it between the kitchen and living area. It clears out any kitchen odors so quickly and keeps everything fresh.

Love the look of these filters. I think they work okay. For the price I did expect to be blown out of the water but it seems to keep up as well maybe a little better than other filters we have.

Wonderful air purifier
on July 25, 2025
Posted by: Debbie P.
I have had this air purifier since Covid. Still works like it did it did on day one. I like the fact it lets me know the air I am breathing is staying in the blue zone. It’s fabulous that the filter lasts me a year.
