## Description

Full description not available

## Features

- 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.
- 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.
- 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.
- 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ niecly designed vent that works very well
*by R***. on May 19, 2025*

I used this soffit vent to add an additional vent to our bathroom. I installed the vent in a vented soffit and wanted to be able to exhaust the damp air away from the vented soffit, to prevent the damp air from being drawn back up into the attic. It works very well and allows the damp air being exhausted to dissipate beyond the vented soffit and into the air. Works very nicely

### ⭐⭐⭐⭐⭐ Bathroom Exhaust Vent
*by C***P on May 29, 2025*

Bit pricey but good quality and design. Seems durable, time will tell. Paired this with 100 and 110 CFM exhaust fans. Rest pictures says it all.

### ⭐⭐⭐⭐⭐ Highly recommend
*by C***S on May 7, 2025*

Good product, but is dirty and easy to use
