For OB1 Filter:
The RS2 is a string wound cartridge for OMNI's U25,
OB1, and OB5 Whole House water
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.
Change filter every 3 months.
Change O-ring every 3rd filter change.
