COMPATIBILITY & APPLICATIONS
Compatible Systems
This replacement filter kit is engineered specifically for Global Water bottleless water coolers, including the G3RO, G4RO, and G5RO reverse osmosis models. The sediment pre-filter extends the life of the downstream 1-micron carbon block by capturing larger particles first, while the carbon block provides chemical reduction and fine particulate removal before water reaches the RO membrane. Both filters use twist-lock housings for tool-free replacement in under two minutes per filter.
💧 Pro tip: Replace both pre-filters at the same time even if only one reaches its service interval. Synchronized replacement ensures consistent flow rate and balanced contaminant removal across the entire pre-filtration stage, protecting your RO membrane and maintaining water quality.
