PC case filters help keep dust and contaminants out of your PC case by allowing only the smallest particles to pass through them and capturing all the larger ones. By filtering all the air drawn into your PC, you can minimize the effects that accumulated dust has in your PC case and on cooling components like radiators and case fans. All forms of PC cooling rely on unrestricted air flow in some way to perform at their best, and dust buildup can prevent this. Things to consider when choosing a PC case filter include size and shape, mounting methods and ease of use. TITAN RIG carries traditional pc case fan filters and Demciflex filters specifically made for many popular PC cases on the market today. DIY cut to size filters are also available that can be cut to the exactly the size and shape that you need to fit your PC case.
