SoffitFlow® 4-Inch HDPE Soffit Vent with Extended Nose & Gravity Damper – Prevents Attic Mold, Stops Humid Air Recirculation – Durable UV-Resistant Exhaust Vent for Bath Fans – Made in USA

The SoffitFlow® Soffit Vent is the smarter way to exhaust bathroom fans and protect your attic from dangerous mold and mildew. Unlike standard soffit vents that dump humid air directly under intake vents—causing recirculation and moisture buildup—SoffitFlow’s patented extended-nose design projects beyond the fascia, breaking the cycle that leads to costly callbacks and warranty claims. Performance Engineering:• Extended nose creates a positive pressure zone, preventing humid air from re-entering attic intake vents.• Precision-positioned 4-inch collar works with a V-shaped tapered bottom panel to increase airflow velocity.• Integrated gravity-assist damper operates at 50+ CFM, ensuring compatibility with standard residential bath fans.• Engineered weep hole prevents condensation buildup, while a hinged wildlife grill allows for easy maintenance. Built to Last:• Constructed from high-density polyethylene (HDPE), delivering superior durability in extreme temperatures (-40°F to 150°F).• Re
