How Our Soffit Vent Works

The PreVent-It under-eave soffit vent has a unique, patented design. It dispels the misconception that soffit vents should discharge air under the soffit. Instead, it is the only soffit vent that effectively directs moist bathroom air from the soffit, preventing that moisture from re-entering the home.
