Stop attic mold before it starts.

Most soffit vents let a bathroom fan's moist exhaust air linger in the soffit, where it migrates into the attic and causes black mold and structural damage. PreVentIt's patented soffit vent moves that air all the way out of the house instead.

Why it matters

Improperly vented bathroom exhaust is a widespread, expensive problem across U.S. homes.

$35B annual U.S. health care cost linked to mold and poor indoor air quality
$73B annual cost to repair structural damage from black mold
$9.5B annual cost associated with improperly vented bathroom exhaust fans

A soffit vent that actually vents

Every soffit vent sold in the US and Canada over the past 40 years vents exhaust air into the soffit, not through it. PreVentIt's adapted termination sits past the exterior of the fascia, so exhausted air is fully displaced out of the house instead of re-entering the soffit's passive airflow.

“I fully support its use in residential new construction projects and existing home retrofits. I would speculate that Pulte's Northeast Corridor Division would purchase approximately 2,000 vents per year for our residential new construction projects.”
