Attic Vents: WhisperCool

Reviewed by:
Rosemary Thornton
This WhisperCool Gable Mounted attic ventilator is thermostatically controlled, so it automatically turns on when temperatures rise.

A built-in humidistat turns on the fan when humidity levels increase. It will move 1,320 cubic feet of air per minute. The unit has a five-year limited warranty.

  • The WhisperCool costs around $395, installed (December 2005).
