  • Excellent product
Color: Oak Size: Dust, Mold, Odors + Heavy Smoke Style: Air Purifier
I thought I had sleep apnea because of snoring and difficulty breathing. I was visiting a relative who had this unit to control dog odors(4 of them) It ran so quiet and the house didn't smell, and my eyes didn't itch. I bought this and after 2 days, my snoring subsided and my breathing became easier. I was so impressed that I bought another unit. ... show more

  • I have become air obsessed
Color: Oak Size: Dust, Mold, Odor + Smoke Style: Air Purifier
What started as browsing for an inexpensive air purifier became a $2000 investment in health. Years ago I took efforts to make sure my water was double filtered coming from our well. To this day our water is the best I have ever tasted. Even my wife noticed the quality difference and she is usually oblivious to such things. Everything started a little over six weeks ago. When I finally decided an air purifier was in our best interest I researched every make and model possible, as I’m sure many of you do. Alen had a few bad reviews, but their specs and design grabbed my attention. Their filters are exceptional and longer lasting. The machines are very energy efficient. My 75i never goes over 20watts. Haven’t tested the 45i yet, but assume it is close. No point in running a machine 24/7 if you are worried about your electric bill the whole time. Alen can be controlled remotely using the GoSund app and it gives you the pm2.5 count as well. Up to this point other reviews have all mentioned what I have said so far. 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. ... show more

Had terrible cough and was told it might be allergies. After installing two of these I am much better. I don’t know for sure if this is the reason but I give it the credit.

Color: White Size: Dust, Mold, Odors + Heavy Smoke Style: Air Purifier
Bought this to help remove the MJ smoke and puppy excrement that my neighbors seem to forget about. 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. ... show more
