About This
- Hydro Guard HDGT-45 RO Filter Replacement Kit, Membrane Not Included: Contains HDGT-SED5 (Stage 1) sediment filter, HDGT-CB5 (Stage 2) carbon prefilter, and HDGT-CB5P GAC post-carbon filter (Stage 4). RO membrane (stage 3) sold separately.
- Built for Annual Maintenance Without Membrane: Hydro Guard replacement filters at Stages 1, 2, and 4 replace every 6 to 12 months. This kit covers the three stages due for yearly service without membrane. The membrane is replaced every 24 months.
- Media Matched to Each Stage: Hydro Guard filters use proven media at every stage — melt-blown polypropylene at Stage 1, activated carbon block at Stage 2, and GAC for final polishing at Stage 4.
- Tool-Free Twist-and-Lock Installation: Every Hydro Guard water filter in this kit uses the quick twist-on design. Replace all three stages without tools every 6 to 12 months.
- Designed for Hydro Guard HDGT-45 Reverse Osmosis Systems: Fits HDGT-45CP, HDGT-45CP38, HDGT-45BN, HDGT-45BN38, and HDGT-45CP-P. For the complete 4-stage kit with membrane, see YSM-HDGT-45.
