The DICOTA 4-Way privacy filter is ideal for working in public environments such as libraries, open-plan offices, airports and trains. It protects personal and confidential data by darkening the right, left, top and bottom of the screen from an angle of +/- 30 degrees. The filter can be attached to the screen with plastic holders, making it easy to remove. The filter also offers protection against scratches, reduces fingerprints and prevents reflections.
