- Install the new 5-micron sediment filter in the first stage housing and the two carbon filters in stages two and three.

- Flush the system for 5 minutes before resuming normal use to remove carbon fines and activate the filters.
COMPATIBILITY
Works Exclusively with Watts Premier RO-PURE Systems
The Watts 531102 filter kit is designed specifically for the RO-PURE and WP-RO4 reverse osmosis systems using 11-inch proprietary filter housings. This kit will not fit standard 10-inch filter housings, Watts KWIK Change systems, or other brands of reverse osmosis equipment. Verify your system model before ordering to ensure proper fit.
🔧 Pro tip: Mark your calendar or set a phone reminder when you install this kit. Filter performance degrades gradually, and waiting beyond six months can allow sediment buildup that shortens membrane life and reduces flow rate.
