Replacement Cartridge Four-Pack

This four-pack supplies 20-inch replacement cartridges built for OptiPure CTOS-20 systems and Global Water G3RO, G4RO and G5RO coolers. Each cartridge is individually inspected by IPW Industries Inc, a Water Quality Association member with 17 years of experience. The set delivers sediment, carbon micron and carbon taste-and-odor filtration in one convenient bundle.

Cooler Compatibility Check

Verify that your cooler is a Global Water G3RO, G4RO or G5RO model or uses the OptiPure CTOS-20 cartridge before ordering. The twist mechanism fits only those housings, so other brands or sizes will not accept the cartridge. No tools are required, but the existing housing must match the listed models exactly.

System Integration

The easy-twist design lets you swap cartridges without shutting off the water supply or using a wrench. Sediment filtration down to 5 microns protects the downstream 1-micron stage, while the carbon micron layer reduces lead, chlorine, cysts and organic contaminants. The carbon taste-and-odor cartridge meets ANSI/NSF Standard 42, and the 50 GPD reverse osmosis membrane restores full production capacity.

Questions about this item

What cartridges are included in the 4-pack and does anything else need to be purchased?

The pack contains four 20-inch replacement cartridges covering sediment filtration down to 5 microns, carbon micron filtration at 1 micron, carbon taste and odour reduction, and a 50 GPD reverse osmosis membrane; no extra parts are required for installation.

How do the four cartridge stages differ so I know which one replaces which stage in my cooler?

Stage one is a sediment filter that traps particles as small as 5 microns, stage two is a carbon micron filter that catches contaminants down to 1 micron while reducing lead, chlorine and cysts, stage three is a carbon taste and odour filter certified to ANSI/NSF 42, and stage four is the 50 GPD reverse osmosis membrane.

What does the 50 GPD membrane rating mean for daily water production on my Global Water G3RO, G4RO or G5RO cooler?

The 50 GPD rating indicates the membrane can produce up to 50 gallons of filtered water per day under standard conditions, supplying ample capacity for typical office or household use on compatible Global Water coolers.
