GWFILTERS 3 Stage Replacement Filter Set
The GWFILTERS replacement filter set uses a three-stage process to remove sediment, chemicals, and microscopic contaminants from municipal water. Each filter targets specific impurities—from visible rust and silt to dissolved lead and chlorine—so your bottleless cooler or under-sink system delivers clean, odorless water consistently.
Three-Stage Filtration Process
5 Micron Pre-Filter
Removes sand, rust, silt, and larger particles from municipal supply lines. Protects downstream filters from clogging and extends their service life by trapping debris before it reaches carbon media.
Replace every 3–6 months1 Micron Granulated Activated Carbon
Uses activated carbon media to adsorb chlorine, pesticides, insecticides, petrochemicals, and benzene. Reduces organic contaminants and cancer-causing compounds that affect taste and safety.
Replace every 6–12 months0.5 Micron Carbon Block
Final stage removes 99% of lead, microbial cysts including giardia and cryptosporidium, and submicron particles. Eliminates residual chlorine taste and odor for clean, crisp water at every pour.
Replace every 6–12 monthsSystem Requirements
This three-filter set fits most Global Water bottleless coolers, Blueline water dispensers, and standard under-sink or countertop filtration housings. Filters install in sequence from inlet to outlet—sediment first, GAC second, carbon block third. Turn off water supply, unscrew old housings, replace cartridges in order, and flush the system for 5–10 minutes to clear air and loose carbon fines. Monitor flow rate and replace filters when pressure drops or taste changes.
