The RS19 is a 150 micron polyester cartridge for OMNI’s U25, U30, 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 larger micron size than cartridges RS1 and RS3, which makes it ideal for removing larger rust and sediment particles, sand and small gravel from your water before finer filtering. Best for people who need a sand pre-filter (for an OT32) and all well water applications.
