'''Strange Filters''' are [[Tools|tool]] items. They are represented by a cartridge filter sitting next to a screen displaying an image with cut red, yellow and blue wires, and some screws lying around. The image displayed on the screen changes depending upon the map the Strange Filter applies to.

Strange Filters can only be used on [[Strange]] weapons and cosmetics. Adding a Strange Filter to an item restricts the tracking of a statistic to a certain map or mode, and adds an extra prefix to the item depending on which criteria the Strange Filter was for. All revenue from purchasing a map's Strange Filter, minus net taxes, is given to the map contributor.

Once a Strange Filter is applied, the stats that the filter is applied to ''reset to zero''.

The extra prefix is only awarded if the Strange Filter is applied to the weapon's primary statistic.
