An inexpensive fresh air intake pre-filtering device for make-up air is disclosed for use with a circulating forced air heating system that is installed on an outside wall of a building. The device is comprised of a polyethylene material, with an outer flange for securing the fresh air intake to the exterior wall surface as a retrofit or an installation on new dwellings. The fresh air intake housing is structured to include an aluminium frame, two sided raised pattern grill of a RX PolyMed filter medium, manufactured from 100% synthetic fibres. This is to prevent vermin, insects, pollens, and other pollutants from passing through, while permitting the ten percent of air flow required by the National and Regional Building Codes far residential housing. This washable filter is easily removed or installed by the pull tab on the front of the vent housing. This pre-filtering device is designed to prevent snow and rain from entering the fresh air intake duct.
