## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great on marijuana smoke! (plus lots of other stuff)
*by P***E on March 10, 2020*

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!

### ⭐⭐⭐⭐⭐ A very good solution for serious air cleaning
*by S***T on October 18, 2021*

I've had this a month, and I bought another as well...and a 45i.I looked at the ratings in Consumer Reports: the 75i had the highest rating of all they tested, so I got it. It is large, and the incoming air vents are large: which means that there is not much noise made by incoming air...and you do not have to run it on the highest levels. I have found the noise to be quite reasonable, and not an annoying sound.One has been in my den which has a lot of books: the dust accumulation has been greatly reduced. The filters have helped with our allergies.I like its simplicity. Fortunately there is no remote control: they just get lost and save no effort in any event. Wifi? Why? There is a light for ordering the filter and then replacing it. You can turn the lights completely off on the panel if you want (e.g., at night).The warranty is apparently indefinite, but it does require a subscription for filters. However, you only need one subscription--no matter how many units you have--and you can choose how often they arrive (from every 6 months on up).The 45i is smaller, and so better for small rooms.About price: I bought all 3 from Amazon (rather than from the Alen website) because the prices were significantly lower. However, SOME Amazon prices were higher (for different covers): you just have to be careful.Also, there are variations on filters: once you get to charcoal filters, the replacements are more expensive (and according to Consumer Reports, the charcoal does not last as long as the HEPA filter).This is the 3rd brand I've had over the years: and I like it the best.The only downside is that it's made in China (although it is an American company).

### ⭐⭐⭐⭐⭐ Really works; very quiet; features and performance are hard to beat
*by X***P on June 13, 2023*

Even if you can't tell by the disappearance of odors and the improved breathability of your indoor air, you can tell this thing is really doing something by watching the lights and fan on automatic, as they work to clean the air.We initially got this when some major concrete work was being done nearby that would've sent cancer-causing dust into our house. We sealed up the doors and windows and even so, this machine knew the air needed to be cleaned and did its job. Since then, we leave it on all the time unless we want to keep windows open for "fresh air", at which time it ramps up, detecting that our outdoor air quality isn't as good as what we have indoors!Ratings in other sources mention that other units are quieter. I have to say that if you're bothered by whatever noise this unit is making on its lowest fan speed, you're ultra sensitive. I have a sound meter and it never shows anything above background noise on the lowest setting, and while you can hear it when you're close to the machine and the room is dead quiet, it's as quiet as anything you're ever going to need. I can hear our refrigerator on the other side of the house when it's on over this machine. Noise absolutely is not a problem!
