Why Buy an Alen BreatheSmart FIT50?

Of all the air purifiers on the market, and we know virtually all of them, we love the FIT50 because the folks at Alen created a unit that can change as your needs change. For example, if your main air quality issue is removing germs and pet odors today, when your kids are grown and gone you can simply change the filter type and the same unit will continue to meet your needs in the future. No need to buy a whole new air purifier. No other manufacturer thought that far ahead!

A style to fit your decor and change as often as you'd like

With customizable designer panel colors, the BreatheSmart FIT50 can be personalized to fit any room and compliment your decor for today or whenever your styles change.

Why Customers Love the Alen BreatheSmart FIT50

From turning it on to everyday use, the BreatheSmart FIT50 air purifier was designed to be easy and intuitive. Set to Auto, the BreatheSmart FIT50 adjusts fan speed automatically when it detects changes in air quality caused by pet movement, doors opening, or the A/C turning on. Long lasting True HEPA filters (10-12 months) are a breeze to change with a simple 3-step process, and a convenient Auto-Restart feature keeps your purifier humming after a power outage.
