PreVent-It Bathroom Soffit Vent 4", Under Eave Exterior Vent, Screws Included, Brown, 1-Pack

The PreVent-It Bathroom Soffit Vent effectively directs vented air from bathroom exhaust fans away and prevents it from re-entering your home. The patented design dispels the misconception that soffit vents should discharge air under the soffit. It was scientifically proven in lab testing at a major U.S. university to discharge 95%+ of exhausted air away from the passive soffit zone. Existing soffit vents discharge the majority of moisture directly under soffits. The problem with those designs is that the moist air can end up going under the roof. That can cause unsuspecting roof damage, water damage, increased allergies, higher utility bills, and/or a negative impact on the environment. Use our patented soffit vent to avoid those potential problems and danger to your family’s health and safety.
