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. A special silicone layer enables easy, bubble-free application and residue-free removal. The filter also offers protection against scratches, reduces fingerprints and prevents reflections.
