I have 3 of the Alen Classic air purifiers, which I love, and now I also have the 75i which is bigger, but quieter. I haven’t yet ever seen this one show red and kick the fan to high because I always have them on, but if I turn it on high manually, it’s still quieter than the classics. If I hold my hand over the top when the fan is on high, it doesn’t seem to blow as much air as my classics either. The fan noise of the classics isn’t so much to bother me, but some of the other reviewers have not liked it, so they would probably be happier with the 75i. I actually like to feel the movement in the air while sleeping so I have a classic in the master, but the 75i works well in the living room since it’s quite even if it were on high. It makes it easier to hear the television without having to turn the volume up a bit to compensate. I like both models, but for different reasons and different rooms. The classic was my first and made such a difference I ordered 2 more and took one to work. The customer service at Alen can’t be beat and I will always go back for an Alen. They are expensive but the improvement in air quality make it worth it.
Love my new Alen BreatheSmart 75i air purifier! It’s plug and go right out of the box. It’s cool look matches the transitional/mid century style of my home. It’s about the size of a large suitcase, however it is not heavy and has a handle to easily carry it around if wanted. It’s amazing to watch the colors change as a smell enters the room/house - everything from dog odors, cooking odors, perfume etc. My husband is sleeping headache free for the first time in a long time. This must be due to the fact that it removes 99% of mold and allergens from the air. The filter only needs to be changed every 9-18 months and they have a convenient filter replacement program that guarantees a lifetime warranty. What more could you ask? Thank you Alen!
Really like the operation of the BreatheSmart 75i. There are 5 fan speeds. The two slowest speeds are quiet enough to watch TV. We put the fan speed on Turbo at night (highest speed). Also like the fact that you can turn off the panel lights if desired. Last, but not least, the filter is very easy to access for replacement. Very pleased that we chose this purifier over the comparable BlueAir model.
I have the 75i for my first floor because my sons have allergies and this has eased their symptoms when they visit. I recently purchased another 75i and three of the FLEX true HEPA filters for a son and daugher-in-law, who are facing a number of health issues and wanted to improve their air qualify. These purifiers do make a difference. Beyond that, I love the design and the ease of maintenance.
