It was one of the best purchases i made, it helped made the room feel more purified and fresh throughout the day. Will definitely purchase more of these products and put it around my home.

The auto dimmer on the lights does not work, but other than that I love it.

One of the best purchases I've made. If you have any pets this is a must. No more pet odor. I like how it tells you the air quality with the top color panel

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!!

Love the look of this and that it’s customizable. It actually runs very quiet. I think it purifies the air pretty good so overall would recommend.

Amazing! My apartment has poor air filtration from the HVAC but as soon as I starting using my 45i air purifier my breathing quality went up a lot.

I am so glad I stumbled on the Alen BreathSmart 45i purifier! There is a noticeable difference in my home and I love that it is quiet, I can adjust lighting and my air is being cleaned! Easy to set up, and the appearance just blends in with my decor.

I bought this as a replacement purifier for my sewing room. I am so satisfied with the purchase and how the dust bunnies have almost gone away!
