Our take on the Alen BreatheSmart 45i Pure True HEPA Air Purifier

The Alen BreatheSmart 45i is a True HEPA air purifier for medium to large rooms, with app control and a color-coded air quality ring. It uses Alen's BreatheSmart filter line, and the gray finish is the standard color. At $488 at ALEN as of November 7, 2026, it sits at the top of its recent range, so it is not a bargain moment.
