Pentek - GS-10CAL/RO - 10" x 2" Coconut Shell Granular Activated Carbon & Calcite Inline Filter
10" x 2" GAC & Calcite Inline Filter
The Pentek GS-10CAL/RO combines granular activated carbon from coconut shells with calcite media to remove chlorine taste and odor while simultaneously raising pH levels in acidic or soft water. This 10-inch inline cartridge works as a final polishing stage in reverse osmosis systems or standalone in any application where low pH correction and carbon filtration are both needed.
Dual-Media Filtration & Remineralization
Chlorine & Taste Reduction
Coconut shell GAC adsorbs chlorine, organic compounds, and other contaminants that cause poor taste and odor in drinking water.
pH Correction & Remineralization
Calcite media slowly dissolves to release calcium carbonate, raising pH levels and adding beneficial minerals back into RO-treated or naturally acidic water.
Final Sediment Filtration
20-micron nominal filtration captures fine particulate and carbon fines for clean, balanced, great-tasting water at the point of use.
Replace every 3–6 monthsTechnical Details
| Part Number | GS-10CAL/RO |
| Dimensions | 10" length x 2" diameter |
| Connections | 0.25" Female NPT |
| Micron Rating | 20 microns nominal |
| Flow Rate | 1 GPM at 125 PSI |
| Max Pressure | 125 PSI |
| Temperature Range | 40–100°F |
| Filter Media | Coconut shell GAC with calcite |
| Service Life | 3–6 months |
Applications & Systems
The GS-10CAL/RO is designed for reverse osmosis post-filtration, food service equipment, coffee and tea brewing applications, and any installation requiring both carbon polishing and pH neutralization. It fits standard 1/4" NPT inline housings and tubing connections common in under-sink RO systems, ice makers, beverage dispensers, and point-of-use water treatment. Replace the cartridge every 3 to 6 months depending on water quality and usage volume, or sooner if flow rate diminishes noticeably.
