This air cleaner made a noticeable difference within the first hour of use. It is very quiet and even on high speed just sounds like a fan running. Very happy with our purchase and it is worth the money.

This is an excellent air purifier and very quiet. Purchasers should be aware that Alen states that the lifetime warranty does not apply outside the USA so Canadian purchasers are out of luck

Couldn’t believe how quiet this Alen 75i is. Set up was easy, back handle, balances unit nicely when moving, also has 2 wheels to make it easier if needed..
My wife was pleasantly surprised and loves the auto mode that increases the fan speed if the laser sensor identifies any additional air particles due to cooking.
Even though this unit was higher priced, Consumers Report rated this number 1, and I can see why.
Filter is expensive but lasts between 12 to 18 months which makes it one of the cheapest to run over time. Most other air purifiers recommend filter changes every 6 months. Look at operating costs when you compare units. Also one of the few energy efficient units available for larger areas.
Highly recommend.

this air purifier was super easy to set up. The noise levels are super quiet and does a great job of cleaning and filtering the air. I am highly satisfied with this product that I ordered two more for the office.

I have asthma and also five large dogs and I live in the desert. I ended up buying three of these machines a big one for the front room and two smaller ones for two bedrooms and let me tell you this I have not found myself coughing, or having a hard time to breathe with these machines going, they are quiet and they do their job. In fact they do it so well that we have cleaned the filters out since purchasing them four times. They seem a little pricey, but trust me they are worth every penny and I’m so happy that I purchase them. I would definitely highly recommend.

This is expensive & I don’t mind spending the money…well designed & very functional – either automatically adjust fan speed or manual. I love the light which indicates air quality (this can be hidden too)…all in all a good investment. I sometimes get whiffs of clean air like the mountains. If you choose to buy one be careful to select the filter to most suite your needs – easy to miss

I purchased this unit to deal with high mold. I just received this unit yesterday and set it up. I have it set to manual as I want it running at max efficacy for a few days to see if I can impact the air quality in my home.
The fan seems to be turning itself up and down on its own? Even on “turbo” it makes very little noise but there is barely any air moving out the back of the unit? I press the power button turn it off and then there’s this huge increase in noise and air movement…..more like what I would expect from a “turbo” setting. But, then it stops. If it were set to automatic that would make sense. But on manual it is doing strange things all on its own.
This is an expensive unit to be so buggy right out of the box. Sending it back before it becomes a long-term headache.

Help to purify the air in our house. Needs to have an operation and code to understand the system.
It is printed on the box but once that is recycled the information is gone.

The window to return it is only a few months. There was no warranty with the purchase offered. No replacement or compensation at all is provided. Calling Amazon they are sorry there is no manufacturing information submitted to have it fixed.
The machine worked for one year. I paid 850. for the machine it cost me 2.50 per day to use it for one year. I don’t recommend purchasing the brand or expecting any help from the seller.

Received this Alen breathSmart 75i purifier today,02-10-21. When I opened the box, I found another box inside, a perfect fit. This inside box was the original factory box. The factory box had been cut opened and the top and front was held together by a nylon shipping band. When I finely got the box out from inside the outer container, I descovered that I had been sent a USED purifier!!!! I pluged the purifier in but it would not come on, DEAD! I looked for the instruction manual, but NONE WERE TO BE FOUND!!!! I called Amazon and talked to a customer service rep. He stated he was sorry,(BIG HELP) and I could return it for a FULL refund. GEE THANKS!! Apparently they send out merchandise like this all the time. BEWARE of this item and company! Order from a reputable company!!! NUFF SAID!!

I’ll get to why I knocked a star off my review in a minute (check out my update at the bottom, back to 5 stars). Just know, this thing is amazing! I wouldn’t call it a great value, but it’s worth every single penny. We have 4 dogs in a single story open design of about 1250 square feet. I instantly noticed a huge improvement in air quality within a short time after turning it on! The auto function works amazingly well. It will be sitting there on it’s lowest fan speed, having successfully cleaned the air all day/night. The little blue circle indicator light tells you your air is currently at it’s cleanest. I’ll light up a joint about 20′ from the purifier and within a minute or so I’ll notice the fan speed crank up to its fullest! (It’s still super quiet though, even on its highest you can’t hear it with a TV on) Red indicator light! Then purple! It tells me right away that my air has been polluted and it’s working to fix it. Within 20 or 30 minutes, the whole house is completely smoke and scent free! It’s perfect for all you well-to-do stoners such as myself. You make good money, you have nice things, you’re a grown up now! You don’t want other adults coming over to your marijuana smoke filled house. Especially all your friends with kids. Or maybe you have kids? What kind of an example are you setting!? Opening the windows on a nice day only does so much. And if you have cold winters and can’t open the windows, what then? You buy this thing ya dummy. All those problems will be solved.
I knocked off a star because my wife is making me return it. She doesn’t like how it looks. I don’t think it’s terrible. It’s the great air purifier paradox: In order for it to work well it’s needs to be out in the open, but to be out in the open it needs to not look stupid. There’s a lot of air purifiers that I passed over based on looks alone. This one I was on the fence about, the color choice of the panel helped push me over. I’m going to add a picture to this review. If you agree with me and think it’s looks not that terrible, leave me a comment! Or if you’re wrong and agree with my wife’s decision to return it, please don’t let me know.
Anyway, you can turn off the panel lights by pressing the big colorful button in the middle while it’s running. That’s obviously nice if you’re gonna use this in a bedroom. It’d be nice if you could turn the panel lights on and off without having to turn the entire unit off. Seems like an unnecessary power cycle just to adjust the lights. But hey, it’s got a lifetime warranty so who cares if it breaks from excessive power cycles!
Long story longer – I’m going to have a hard time replacing this with something else, especially with how well it works. The bar is set REALLY high for cleaning the air in my house now after owning this thing for only a few days. I’m addicted to the fresh air. I work from home and spend a lot of time here. It feels really nice. I will caveat this entire review and say this is the first air purifier I’ve ever owned. Maybe they all do pretty well? Most of the major players have good reviews. I think it comes down to aesthetics when you spend this much. We don’t have a ton of space in our house, so this thing has to sit right out in the open for everyone to wonder and ask what it is. It has to look good. I’ll admit that it’s not the sexiest. Unfortunately, function over form is losing this battle to form over function this time.
P.S. – what maniac thought purple was the right color to indicate your air quality is at its worse!? Why would red indicate the second worst air quality?? Is there some standardized air pollution color rating system that I’m just not aware of?
****Update 2 weeks in, back to a 5 star review****
OK, we tried to replace this unit with a different, more aesthetically pleasing purifier. We tried the Coway AirMega 400. It looks great, covers a similar square footage, and has even better features than this Alen 75i unit….but it flat out just didn’t work as well. It was also MUCH louder. With this Alen 75i unit in the same exact position as the Coway AirMega, the air was noticeably cleaner and smell free. Also, on it’s loudest setting the 75i is hardly noticeable with a TV on. The Coway AirMega was at least 4 or 5x louder on it’s loudest setting…to the point where you didn’t want to run it on it’s highest setting unless you weren’t home.
We tried this unit in a few different positions around the house, some out of the way where it didn’t work as well, and now in it’s new spot (different from the pictures I posted) and it’s seriously great! My wife isn’t thrilled with the spot we landed on, but it works really well and isn’t as bad as she once thought. Seems that function over form has come through to win in the end!
