The Best Alen Breathesmart Air Purifier’s Guide & Reviews

Alen is basically good at releasing armfuls of confusingly-named air purifiers and essentially leaving us to figure out the differences. The Alen BreatheSmart is one in between those, slotting it among the Alen BreatheSmart FIT50 and Alen BreatheSmart 75i – the flagship. Since the FIT50 range is Alen’s mid-tier offering, that places the Alen BreatheSmart within the center of the high.
