Nice unit. Auto mode varies speed as needed, opening doors more often causes higher speed. Most of the time I don't even hear it. Consumer Reports test sealed the deal. Lifetime warranty, you can't go wrong.
Delivery of unit was swift. Set up instructions easy to follow. Noticed improvement in air quality within a day. Unit set on automatic responded to changes in air quality almost instantly, as indicated by color change and increase in fan speed. Very quiet operation, don’t even notice it is running. Very pleased with our purchase.
Alen BreathSmart 75i is by far the best air purifier I’ve ever owned. I have 3 other top rated brands but none come close. Consumer Reports rated this the top and that’s accurate. It’s so quiet and I love that it detects odors and changes color when your air is pure. It’s nice looking, has wheels which makes moving easy. Clears the air from kitchen cooking smells amazing quickly. Helps with dust as well. I just ordered my third. I highly recommend Alen products.
This has been one of our best purchases ever. Our allergies are so much better! The air in the house is so fresh. They are easy to move and use. We plan on buying 2 more next year.
I purchased this purifier and have been using it for 2 weeks and have been very satisfied with the elimination of odor. I have pets and my house is old. I would definitely recommend this air purifier
Beautifully designed with easy to understand display. Installation was simple with quick stet-up instructions. Having the i75 in our bedroom has helped improve our air quality immensely.
I am very happy with the purifier, it is so quiet you can’t tell it is working. We had an old unit in our bedroom that produced ozone, I can tell the difference in the air quality. It looks good, I have it in front of a wall with white cabinets. I was surprised by the size and weight of the unit. My husband had to carry it upstairs for me. My only suggestion would be to have 4 wheels so it is easier to move around. That the reason I gave it 4 stars instead of 5. stars I would recommend it.
