5 Stars
Excellent air purifier
A great air purifier. Operation is quiet, no need to turn up the tv or move it out of a bedroom. Comparable with Gosund app so you can see your air quality from your Alexa app. The fan speed automatically adjusts according to the pollutant level in your home. This got a workout this year with all the wildfire smoke. I even brought it outside to briefly get measurements on outside air quality. I’ve had my Alen for 2 years and I’mvery satisfied with it. Filters are expensive but don’t need to be replaced very often.

5.0 out of 5 stars More sleeping, less sneezing
Reviewed in the United States on July 21, 2022
It was summer in Seattle and the blooming things were exploding with delight, unleashing a blanket of pollen on the city and providing job security for the makers of Sudafed. I'd grown weary of sneezing myself to sleep at night and of constantly vacuuming up dust. It was the summer I turned to air purification for my salvation.

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.
