SOFFIT VENT

Anneliese Khalil, Utility Patent Pending USPTO Application #62011748 The Soffit Vent patent establishes the function of moist air from a bathroom exhaust fan and the soffit’s cool air passive air stream for the attic air flow.

The Background

The International Code Council (ICC), government agencies, and the building industry as a whole has not addressed the challenge of venting a bathroom exhaust fan through a soffit without the risk of the exhausted air backdrafting into the attic through the surrounding soffit. The soffit vent invention described herein solves this problem.

The International Code Council is the standard by which all states follow for residential new construction and existing residential retrofits. The code states that all bathroom exhaust fans must ventto the exterior of a structure. The primary reason bathroom exhaust fans must vent to the exterior is to displace moisture out of the structure. Effective moisture displacement subscribes to effective removal as well as inhibiting reentry into the structure. Effective displacement of moisture helps prevent mold growth, structural damage and potential health and safety issues related to poor indoor air quality.

Venting a bathroom exhaust fan through a soffit is one of the most common methods of venting. While it is an effective method of displacing moisture out of the home; it is not an effective method of inhibiting moisture from flowing back into the attic. Through existing soffit vent terminations, the moisture from the exhaust vent remains in the soffit’s air stream. Because the soffit is a passive air intake, any moist air that vents to the soffit and stays within its passive air stream has a very high probability of ending up back in the attic.

The Solution

The Moisture Flow Soffit venting solution is an adapted bathroom exhaust fan termination that effectively displaces moisture to the exterior and inhibits moisture from flowing back into the attic. This groundbreaking design displaces the moisture outside of the soffit’s passive air stream, moving the moisture from the bathroom fan exhaust effectively away from the home.

The implications of this product are significant, as it is the only product on the market that gives building professionals and homeowners a safe and effective way to vent a bathroom exhaust through a soffit without risking the exhausted air from backdrafting into the attic.

The Description

The product is designed to evacuate hot moist air from a bathroom exhaust fan vented to a soffit. The front nose exhaust of the vent has been sloped to terminate flush with the exterior edge of the facia. The upper edge of the termination extends approximately 1/4 inch beyond  the facia to place an end cap of fixed baffles angled upward to direct exhausted air away from the structure. The end cap is designed to be removable for cleaning.  This product will always be  protected from outdoor elements, as it is sitting completely under the eave.

There is a “drip tongue” on the underside of the vent, centered and at the base. This feature is designed to evacuate condensation immediately, primarily in cold climates, and to prevent ice damming from forming on the product.

The termination point is angled toward the house eliminating surface area at the end of the vent, which is where ice damming is most likely to occur. The end of the vent has fixed baffles on an upward angle designed to direct the exhaust air up, out, and away from the home. The fixed baffles are also designed to prevent back drafting and from large animals (i.e. birds) entering into the vent. Mid way into the vent, there is a backdraft damper, which is designed to prevent back drafting as well. Directly before the end of the vent there is a mesh screen, which is designed to prevent insects from getting into the vent without negatively impacting the static pressure inside of the vent.

The product is designed to fit a range of soffit sizes. There are prefabricated ridges on the body of the vent, giving the installer the ability to make a clean cut and custom fit the vent to the soffit. The product is designed to adapt to any existing insulated flexible duct with a 3”, 4”, or 5” diameter.

The Moisture Flow Soffit Vent is a down venting system. Down venting, rather than up venting, works with the laws of physics rather than against them. Working with gravity – rather than against gravity – helps conserves energy, saves money, and promotes longevity of the bath fan. Down venting also helps prevent condensation in the bath fan’s transition duct because stack effect is no longer acting upon that duct.

The soffit vent is made with UV stabilized lightweight polymer. The color is white. It requires no tools to assemble and a screw driver to install. It is designed for homeowners and professionals alike to assemble and install within minutes. It has a limited lifetime warranty.

It was designed for the more than 50 million “Do It Yourself Homeowners” in the United States to install the Moisture Flow Soffit Vent. The installation only requires small hand tools and is easy to install.

Thank you for interest and your support. The benefits of the Moisture Flow Soffit Vent invention are substantial. The product now provides a safe and effective method of Fixed baffles inside of vent throws the exhaust air up and away from the soffit and home venting a bathroom exhaust fan to a soffit. It will also eliminate the cost of damages annually caused by improper bath fan venting in a person’s most valuable asset: their home.
