Cartridge RS2 
The RS2 is a string wound cartridge for OMNI's U25, OB1, and OB5 Whole House water filters, the Omni Undersink OT32 as well as the older models R12, R14 and Omni Regular Whole House water filters.  It has a smaller micron size than cartridges RS1 and RS3, which makes it ideal for removing small rust and sediment particles from your water. This cartridge replaces the RS2 SS and DS.
