Alen - BreatheSmart 45i 800 SqFt Air Purifier with Pure HEPA Filter for Allergens, Dust & Mold - White

I like my BreatheSmart 45i. The air quality indicator is a very nice feature, especially when use in conjunction with the app to compare to outdoor air conditions. It is very quiet running in the lowest setting at night and has a very sleek and modern design.

Mechanically it works as it should. We have had it running for a few weeks now and the pet smell is still present? Don't really know if it's done anything at this point. For clarity, we have this unit in a room that's 12 x 12 which is way overkill. We expected to be in unbelievable but we haven't gotten the olfactory sense of satisfaction. Our other loss of positive connection is the WiFi…it simply doesn't work on our unit. Not 5G and reset several times….connection unsuccessful.

We both suffer year-round with allergies and also have 2 large dogs that shed. Placed this unit in the bedroom and ran it full speed for 6 hours then set it on auto. Air quality sensor shows clean air and fan runs mostly on low and medium speed. This thing is dead quiet. Control panel lights can be turned off not to disrupt our sleep. You cannot tell that two dogs sleep in that room, and our allergies are well controlled while we sleep.

I bought one for the bedroom and I couldn't believe how well we slept at night as well as how much dust and dander the filter catches. It worked so well I bought a second for the living room. There lest dust I the house and the air is so much better.

I've reviewed and researched different purifiers through Google and Consumer Reports which is how I found Alen; prior to this I hadn't heard of them. I am very pleased with the product; it is quiet and does a great job at keeping our indoor environment clean and healthy.
