PSA filter

Abstract

The PSA Filter is a non-electronic air filter utilized in the interior or exterior of any device which uses air movement as a means of ventilation or circulation including, but not limited to a computer, printer or any other type of electronic or non-electronic devices. This invention consists of a base substrate which is covered with a PSA (pressure sensitive adhesive); such that the PSA material applied to the substrate is the active filtering element, this PSA coated substrate is inserted into or on a device for the purpose of trapping dirt, dust, pollen, fibers, and any additional types of air borne contaminants, that may inadvertently enter from the outside environment through factory installed vents, or that may be created inside of the device from its normal operations, thus said contaminants become trapped onto the PSA filter surface through air-circulation.
