Love our Alen air filter, it’s quiet slick and does the job. The lock and dark mode functions are super helpful with having kids playing with the buttons. The filter removal is easy and it’s helped us quite a bit through the fire/smoke season.
Purchased one in March 2020 for main living area. Amazed by the filtration and corresponding amount of particulates filtered out (after looking at the filter one year later). Purchased a second unit for our bedroom and the freshness is constant and noticeable each time you walk in the room.
I’ve purchased a 75i and had it one a few months. I would notice ever time I cooked the sensor would change color within a few minutes. They also painted the apartment above me and the paint fumes were coming through the air vents. Sure enough the 75i sensed the paints fumes as well and started to work.
I also noticed less dust on my ceiling fan blades. Curious I checked the 75i filter and was astonished how much dust it had trapped. I’ve since purchased another and is great knowing my home and my family’s air quality is top notch!
We've had our Alen for about a week now and it's GREAT! We've moved it around the house a bit to see where it works the best (following the suggestions on the box) and no mater where we put it the air is fresh and we can both see and hear when it turns itself up to freshen the air in the house as needed. An excellent purchase for our home.
Loving this air filter. It is easy to move with the wheels and I love the look. I know a few people with other brands of air filters and they're SO loud compared to this one. We've been remodeling our home and tons of dust is flying around, we have two dogs, and allergy season has been relentless....but this air filter tackles it all.
