Alen BreatheSmart 75i review: a powerful air purifier for large spaces

Alen BreatheSmart 75i: two-minute review

While there are plenty of air purifiers on the market, most of them don’t come with the power of the Alen BreatheSmart 75i. This model stands out for being suitable for larger spaces – up to 1,300 square feet. In fact, Alen advertises that, at its highest setting, this model can completely cycle through the air in a room in 30 minutes. For that level of suction alone I think it’s a worthy contender for inclusion in TechRadar’s best air purifier ranking. 

Power isn’t the only thing the Alen BreatheSmart 75i has going for it, though. It’s available with three different HEPA filters, and it’s easy to use with its capacitive controls, an LED indicator for current air quality, and the ability to track your space’s air. For more remote control there’s app support, although it’s strangely well hidden.

The build quality is high and the design is attractive if understated, falling more on the discreet side of air purifier aesthetics. You can change out the faceplate for different colors, to blend in or match your decor. It’s also very easy to set up – you basically pull it out of the box and remove some wrapping it’s ready to go.
