Abstract: A universal filter apparatus is described which provides, in a single unit, an anti-glare and/or anti-static screen and frame which is adaptable to monitors of varying sizes. The universal filter apparatus includes a filter screen mounted to a housing. The housing includes a front side, a top side, and at least two lateral sides, each of the at least two lateral sides extending perpendicularly from the front side. A elastically deformable nonresistant securing device is attached to each of the two lateral sides to allow the apparatus to be easily installed on monitors of varying sizes.
