Basic Filters

Basic filters like the EZ Flow and KOCH C&I Disposable filters are a great choice for low initial pressure drops and robust construction. Because of the low pressure drop of basic filters like fiberglass or spun glass filters they are recommended by many HVAC technicians. Some systems require less resistance when compared to a pleated style filter. Basic filters are a solid choice to protect residential and light industrial equipment. They also help keep heating and cooling coils clean, which lowers energy bills. You can find a basic filter here at RTF, guaranteed to be available in your size.
