INSTALLATION & USE

- Flush system for 10 minutes after installation to clear carbon fines and activate filters
COMPATIBILITY
System Requirements
This replacement filter kit is designed specifically for Goldline-50 reverse osmosis systems manufactured by Isopure Water. The kit maintains the original three-stage prefilter and single-stage postfilter configuration. RO membrane is not included with this kit and should be replaced separately every 2 to 3 years depending on source water quality and usage volume.
🔧 Pro tip: Mark your calendar for annual replacement, but if you notice a significant drop in water production or taste quality before the 12-month mark, replace filters early. High sediment or chlorine levels in your source water can exhaust filters faster than expected.
