Abstract
Abstract An air filtering device for a motor vehicle having a vent for air intake. The air filtering device includes a housing having a plurality of apertures disposed therein, a filter element, and connecting means to removably couple the housing and filter element to a position overlying the vent on the motor vehicle. The housing engages the body of the vehicle, and the filter element is positioned within the housing so that air normally passing into an air intake vent first passes through the apertures located in the housing and is filtered by the filter element. The air filtering device can take a variety of shapes and sizes so that any vent orientation may be adequately fitted and filtered. The air filtering device is easily removable for cleaning and/or replacement of the filter element.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
192 words
An air filtering device for an over-the-road truck having an exterior body with at least one air inlet therein providing communication to a heating and air condition system of the truck, the air inlet having a screen therein, the device comprising: a housing having an outer wall, a sidewall extending from the outer wall, and a substantially planar perimeter flange extending from the sidewall, and having a plurality of apertures extending through the outer wall, said housing positioned on the exterior body of the truck over the air inlet; a filter element positioned within the housing adjacent the air inlet for removing airborne particles from the air; and connecting means extending through the housing to engage the screen for mounting the housing over the air inlet on the exterior body of the truck, the connecting means being removably secured to the screen, the flange of the housing engages a portion of the exterior body of the truck surrounding the air inlet, whereby air is first passed through the apertures and the filter element to remove particles from the air before the air enters the heating and air conditioning system of the truck.
