More Details
Main highlights
- Scientifically proven to displace the most amount of exhausted air away from the home (95%+ of moist air). Don't put your family's wellness or the health of your home at risk by using a less effective, cheap soffit vent.
- Patented design and only soffit vent built to direct moist bathroom air away from the soffit, not under it. This prevents several issues, including water and roof damage, increased moisture resulting in higher heating and air conditioning costs, and indoor air quality issues that can impact health.
- Easy to install; easy to clean via removable screen; fits a 4-inch vent hose (4 screws included).
- Durable resin plastic that's weather resistant; Made in the USA.
- Damper/flap provides a closed system that prevents pests and air from entering home. The small front grill openings help increase air speed to push moisture over the soffit edge. Note: Meant for bath fans up to 110 CFM. Higher CFM fans may experience louder fan noise and restricted air flow.
