Fighting even the toughest air quality challenges

from wildfire smoke to heavy air pollution—is no sweat thanks to FIT50’s oversized motor & extra-thick filters. Our #1 recommended purifier for wildfire zones can help create an EPA-recommended clean room for refuge from toxic smoke. And FIT50 can easily tackle your everyday air quality concerns.

Pro-Grade Filtration

With the most activated carbon of any filters in its class, the FIT50 is tough on toxic pollution like smoke and dangerous household VOCs (volatile organic compounds) from cleaning products, paints, new furnishings, and many other common sources. Tiny fractures in activated carbon trap chemical particles to leave you with safer and fresher-smelling air.
