Reduced temp and humidity in Attic
Very pleased with the vent. We had an issue with high humidity in the attic and the fan has helped to equalize the humidity with the outside and reduced the temp which is an added plus. The fan makes noise, but it cant be heard once you close the attic door. Great product. Lets see how long it lasts!
