Abstract: A filter kit for electronic equipment such as personal computers and stereo amplifiers. The kit includes frame material having a total length of at least two feet, a generally "U" shaped cross section and a width of less than 11/2 inches, at least one square foot of air filter material and material for attaching a frame made from the frame material around the air intake of the electronic equipment. In a preferred embodiment, the filter kit contains rubbery vinyl gasket material, filter material and double-sided tape. A filter frame large enough so that it fits around the air intake to the electronic device is made from the gasket material. The frame is then attached to the electronic device with doublesided tape or it may be glued in place. Finally, the filter material is inserted inside the frame. The rubbery nature of the frame permits filter replacement (even stiff filters) without removal of the frame from the electronic device.
