RS1 OMNIFilter family of cartridges are manufactured from a pleated cellulose media and are designed for general water filtration purposes. The media is pleated around a polypropylene core for added strength. The pleated endcaps of the standard cartridges are immersed in a thermo-setting vinyl plastisol. The pleated ends are sealed to the endcap with a thermoplastic adhesive. The overlap seam is sonically welded to reduce bypass, improving filtration efficiency. RS1 cartridges are economically priced and highly effective at reducing sediment particles down to 20 microns in size.
