Check Valve - Fan Reviews

4.1 Rating 79 Reviews
Installed temporarily in a window. Works well to vent moisture and smell. Accidentally cooled down porch when left on with central air. Wish it came with its own window shield.

It is an affordable fan. Not sure how long it will last, but works fine for its price.

Used it as an ad hoc vent fan. Helped with mirror fog and odor elimination. Plastic design, but quiet and effective.

The flaps don’t open fully when running and don’t close properly when off.

Extremely easy to install. Suction for workshop fumes is great. No more alarms.

Easy to install cause u can get a 4” holesaw easy. The noise level is a little high for the amount of air or moves but not terrible. I put a clothes pin on the flaps to improve air flow.
