Designed Better to Perform Better

Filter ridge vents provide an effective method of exhausting damaging heat and moisture from under roof surfaces while providing optimum protection against insects and weather from entering the building. However, not all filter ridge vents are created equal.

Internal Filter Vents Clog from Internal Debris, Cannot be Cleaned

Conventional internal filter guards can become clogged over time with air dust particles that reduce, or completely stop air flow from under roof surfaces causing damage due to moisture and heat buildup. These types of internal filter vents cannot be economically cleaned.

Ever-Flo External Vent is Self-Cleaning

Ever-Flo's patent pending external filter guard keeps weather and insects out of the building while assuring long-lasting ventilation performance. Rain water automatically passes through the filter and naturally cleans it, passing dust along the vent's channel. Should the filters ever become clogged, they can be easily removed and cleaned with a spray of water.

Protects Against External Debris Buildup

While conventional internal filter vents use an open channel design to exhaust heat and moisture, that channel can become clogged with twigs, leaves, pine needles, and other debris. The advanced wind baffle design used in the Ever-Flo vent eliminates this problem by providing a flat surface so any debris just blows away.
