Abstract: A method of forming a custom air filter is disclosed. In accordance with the method, a first air filter having a first size is provided. A length of support material is also provided and includes a substrate covered with a pressure sensitive adhesive, over which a release layer is disposed. At least a first portion of the first air filter is cut and removed to form a nascent air filter. The length of support material is manipulated to have a channel configuration, and the release layer is removed to expose the pressure sensitive adhesive of the length of support material. The length of support material with the channel configuration is pressed into engagement with the nascent air filter such that the exposed pressure sensitive adhesive bonds to the nascent air filter, thereby forming the custom air filter.
