Love them!

I bought 2 of these earlier this year. Best purchase ever. I can breathe better now thanks to them. We live on a high-traffic road, so there is a lot of dust and pollen, and this air purifier literally filters most of the particles out automatically, and will indicate the air quality, then adjust on its own accordingly!!

Changer for My Living Room!

We use the Alen i45 in our living room and have been extremely happy with it. It runs quietly, looks great in the space, and noticeably improves air quality. The air feels cleaner and fresher, and it's made a real difference with dust and everyday odors. Setup was quick and easy, and it's been reliable ever since. Highly recommend for anyone wanting effective, low-maintenance air purification.

Peace of mind

I did a lot of research on air purifiers after having mold grow on a home ERMI test and landed on this brand. I couldn't be happier! They are stylish, quiet, and my allergy symptoms are so much better. I am super happy with all 4 units I bought and have great peace of mind that my air is clean especially during fire season.
