Abstract: A pre-filter kit and related method of use with an air filter associated with an intake of a machine is provided. The kit can include a sheet of pre-filter material, an adhesive component, such as an adhesive on a release liner, and one or more optional bands. The method can include: measuring a height of the air filter, cutting the sheet of pre-filter material so that the sheet includes a top edge and a bottom edge separated from one another by the height, as well as a first end and an opposing, second end; applying adhesive to the first end; and wrapping the sheet around the air filter so that the first end overlaps the second end to secure the first end to the overlapped portion of the sheet. The pre-filter is secured to the air filter so as to impair dirt, dust and debris from entering the air filter.
