Questions & Answers


There are mixed reviews with all the Alen purifiers. I need to know which one will purify the air...

Asked by Miss April 29, 2021

75i will purify the air from airborne mold spores and allergens, but to be clear, it will not remove mold from a wall - you would probably need to scrub that with bleach, but if you are cleaning a room that has mold in it or just have an allergy to mold, this unit will trap those airborne pollutants. I have one in my living room and love it.

Is there a Difference between the white and Walnut in function of the 75i

Asked by ted January 27, 2021

No, just a different cover for different aesthetics. The unit functions all the same but you could get different filters (hepa, hepa-odor, hepa-pets, etc). I’ve been using these units since 2019.

Purchased 5 units for our
Purchased 5 units for our hands-on science center that is in a building where we don't have control over the air handling system. The Alen units have been a wonderful way to purify the air for our visitors and increase their confidence to return to regular trips with their children. The units run extremely quietly, and we especially appreciate the display that shows the air quality in a colored ring. The locking feature is important in our public space.

I LOVE the Alen BreatheSmart
I LOVE the Alen BreatheSmart 75i. I own 3 of them! I also own 3 older units. I love the design and the expanded air quality register on the 75i. Great machine!!!!

Superb Machines
Top-notch product - effective, efficient, quiet and attractively styled. I have now purchased 4 Alen air purifiers over the past two months (2 BreatheSmart Flex, 1 BreatheSmart Classic, 1 BreatheSmart 75i). The units have truly transformed the air quality in my home. Very convenient to simply clean the pre-filter with vacuum attachments. I have a number of pieces of dark wood furniture throughout my home, and the reduction in visible dust since I have employed these units is truly remarkable.

Great Filter
I was perhaps a bit shocked how physically BIG this unit is but it's stylish and I no longer notice it. What I do notice is CLEAN AIR. We have a lot of allergy problems in my household and the Alen BreathSmart 75i seems to be doing an excellent job of removing particles, odors and pet dander from the house. You can actually watch it work. The status light tells you the quality of the air. When somebody goes in or out of the house or something fragrant is cooking, the status typically changes to lower quality and the "auto" setting kicks the fan up higher. If it isn't working fast enough for you, you can manually turn the fan up to high speed and the air is typically clean in minutes. And it's QUIET. We don't even notice it, most of the time.

Ultimate Style Barbershop. Ultimate purifier!
Very satisfied with this product so far. It was easy to install, quite and seems to be effective. I’m using it in my place of business and It’s really a noticeable improvement in air quality. I’m using the Alen BreatheSmart 75i with B7 fresh filter. The purifier fits nicely into the space I had planned for it in my business. I went with the white version to compliment the white walls in my business.

Breath of fresh air! Excellent
Very well made and yes it’s quiet, sensitive to minute air changes, it’s really effective. This is my first air purifier but I did a lot of research and this unit does not disappoint! Yes it’s a bit more then some but average the use and quality performance over the long term it’s worth more. That said the controls are super easy to use, I just leave it on auto mode and it knows what to do. My space is mostly a large open area so this is ideal. I’m a happy satisfied customer!

Good Purchase
The Alen BreatheSmart 75i has worked well to keep the air clean. I am very satisfied with the performance and the way it quietly works.
by Thomas B.
Great purchase
We can feel a cleaner air at home, our son had a sort of allergy, he used to sneeze and cough every time we used the vacuum cleaner, that stopped when we let the Alen purifier work.

Keeping my house healthy
The pollen in Georgia is very high. My mornings are horrible. Since I got Alen BreatheSmart 75i, I can tell the difference in the area that covers about 1300 square feet. I don’t have to take Allegra!!
by Marilyn M.
Great Purifier!
Needed a bigger unit for our large family room with adjoining kitchen. Opted for the kitchen odor filter for cooking smells and it works great! This our 3 rd unit in the household and we love all of them! Can’t beat the lifetime warranty either.
