  • I have become air obsessed
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

  • Great Sensitivity to Air changes - Quality Product
I wanted to allow myself some time to review this, and observe the Alen BreatheSmart in action before I wrote a review on it. I can say that of all of the air filtration systems, I like this one the best. Definitely superior to my old Winex and has better sensitivity than my Sharp FP-F60UW, with a respectable CADR rating. It's really useful in getting rid of cooking smells and returning the air to a neutral balanced feeling. The control panel and features on the device feel well made, and have good tactile response. The wooden decorative panel also makes it a bit less obtrusive in the living room. On its highest setting, you do hear some wind noise, but its not nearly as disruptive as some of the other brands I've owned. I'd purchase this again. ... show more

  • Effective, quiet, nice appearance
With the Bay Area full of smoke particles of variou sizes we kept our house closed up but there is still infiltration. We liked reviews of Alen products so two smaller units met our needs for living area downstairs and bedroom upstairs. The unit looks well made, functions well on automatic mode and it not too loud for the bedroom at night. This week (Sept. 28) is another 5 days of "Spare the air," can smell the smoke outside, but inside is relatively peaceful. We can breathe. ... show more
