I bought the Alen 45i on the recommendation of Consumer Reports. After a few initial hours on turbo, it settled into a quiet cycle on auto mode and I haven't had to touch it since. Pretty quickly, my dust level was significantly diminished and I was sleeping better. I found that when I walked downstairs in the morning I would immediately start sneezing, so I ended up purchasing the larger 75i for my living room (probably overkill for my space; it's a gigantic beast). Both units are extremely quiet unless they're on turbo — but they call it turbo for a reason — and they're super-easy to setup and use. They also look nice, and I like that you can turn off the display light on the 45i so it doesn't cast unnecessary light in the bedroom at night.
So far so good on the filter, though I haven't had it long enough to say whether it's as long-lasting as claimed. Assuming it continues to perform I think it's worth the investment for cleaner air and better sleep.

I bought this and after 2 days, my snoring subsided and my breathing became easier.
I was so impressed that I bought another unit.
I studied cadr rates and air change intervals ad nauseam. The thing I learned is that the square footage claims by all manufacturers are exaggerated if you truly want allergy free air or close to it. A cadr of 247 might effectively filter up to 375sq ft not 800 ft. That is figuring closer to 5 air changes vs 2 per hour. Again all manufacturers do this. I’m running two 75i’s and one 45i in an area of 1400ft with high ceilings. Is my air cleaner than it ever has been? You bet. One would of helped for sure, but the three working together purify the air a little quicker and much more often. It still takes an hour or two to get air quality at good levels after cooking. No exhaust fan present in our house. I got Covid a month ago today and I honestly believe the quality of my air made an incredible difference. The H13 hepa filters most likely reduced the amount of the virus in the air along with a hepa vacuum. I know most people can not afford more than one of these. For bigger spaces a 75i is where you need to be looking. If sleeping problems are more of an issue than the 45i is perfect for bedrooms. It is where I have mine.
Alen reminds me of Apple. I resisted Apple for years. Telling myself they were overpriced and overhyped. I’m writing this review on an iPad so what does that tell you? Once you are on their ecosystem everything else looks inferior. Same thing with Alen. When I was shopping for my third purifier on Black Friday I was only looking at Alen. They make you feel good about their products, service, warranty, and overall quality. We all need to feel good a little this year and not like you can go on vacation. Alen is an American company, so at least some of the benefit stays here. Look if you have read this far you most likely have an interest in this product. Try one. A 75i if you can swing it financially or a 45i if you have a smaller space or Christmas spending has got out of hand already. You will never know what you did without one. Oh and if you buy a second or third I’m betting it is an Alen.
Thankfully, I don’t smell it in my room whilst I slumber. If it hits my nose in another room, I’ll drag it out of my room, close the other doors so it focuses on the smaller area and helps some. Either the people moved out, stopped smoking indoors, cleaned up after their animals, or this is working. Not sure for certain, but I’m not complaining.
It helps drown out noise, as it also functions as a white noise apparatus, though not advertised as such since many people like quiet. If someone doesn’t, then pop in some earplugs (Recommend Loop Pro +18dB on Amazon)
Regardless how much I vacuum, dust, wipe, clean, or wash stuff, it doesn’t seem to help, so I got this. During various points in the day the light changes color to indicate level of filth in the air (I don’t have animals but neighbors walk their dogs past my door, so when I open my door I’m sure dander has made its way in my residence. I noticed that it works harder when the heat is on. (Purchased in late Feb.) **Changing out the furnace filter more often helps the quality of air, and stops me from coughing, IMO.
So, to sum up, having this has helped. Keeping it on high makes more of a difference than keeping it on low (or one of the 4 settings). My air is crisper if that makes sense, like when you can finally breathe after being congested, taking large chestfuls of air in, or like fresh mountain air.
Yes, the filter isn’t cheap, but it’s good for a year, pending the level of filth it has to clean throughout the year. I’m checking it monthly because I’m retentive like that, but I’d rather be able to breathe and not blow my wad on something I don’t need than something I actually do.
Top reviews from other countries
I have dust allergies and this does the trick. I sleep well and I dont have as bad of a plugged nose in the morning as before.
The machine is simple to operate
The machine has a vacuum-able pre-filter
The machine has a life time warranty as long as you subscribe to the Alen filter replacement program within a year of purchase which is a BIG DEAL.
The machine’s HEPA filter lasts 12 months.
The machine is very quiet in the lowest settle and sounds like a white noise machine on the second lowest setting.
The machine is very light. I move it from room to room all the time
The machine is good for 800 sq ft of space
The machine is very nice to look at!
One con is the manual sucks. Sometimes my machine has this wifi looking symbol on and I dont know what it does. The machine becomes possessed and starts cycling through fan speed and turns off on its own. It only happened once and I dont know whats going on.
Mir wurde zunächst irrtümlicherweise ein Gerät ausgeliefert, das für den Markt im UK bestimmt war und daher nicht den passenden Netzstecker für deutsche Schuko-Dosen hatte. Das Problem wurde sehr professionell, schnell und umstandslos von Alen International zu meiner vollkommenen Zufriedenheit gelöst.
Viel Plastik, sitzt aber trotzdem alles gut und wackelt nicht.
Der Filter lässt sich gut tauschen und wirkt robust.
Weitere Punkte zeigen sich vermutlich in den nächsten Monaten, bisher ein sehr guter Eindruck.
Mir wurde zuerst das falsche Gerät zugesendet. Nach einer Rücksprache mit Alen UK (Verkäufer) haben die super reagiert, sich gut gekümmert und auch nachgefragt ob alles in Ordnung ist. Habe ich so noch nicht erlebt, dafür auch volle Punktzahl.
