About This
- ✅COMPLETE 2-STAGE KIT — SEDIMENT + CARBON: Includes one PP10 sediment cartridge and one CTO10 carbon block cartridge for full two-stage filtration. Stage 1 captures the particles; Stage 2 polishes the taste. Everything you need to refresh a standard 10" two-stage system in one kit.
- ✅STAGE 1 — PP10 SEDIMENT (REDUCES DIRT, SAND & RUST): The melt-blown polypropylene cartridge reduces sediment, dirt, sand, rust, and fine particles — protecting your plumbing, fixtures, and the carbon stage downstream so your whole system lasts longer.
- ✅STAGE 2 — CTO10 CARBON BLOCK (REDUCES CHLORINE, TASTE & ODOR): The activated carbon block reduces chlorine, bad taste, and odor for noticeably fresher, cleaner-tasting water at the tap — ideal for drinking, cooking, and beverages.
- ✅NSF/ANSI 42 MATERIAL-SAFETY CERTIFIED: Both cartridges are certified by IAPMO R&T to NSF/ANSI 42 for material safety, so the media that touches your water meets recognized safety standards. Contaminant-reduction performance is verified through manufacturer testing.
- ✅UNIVERSAL 10" x 2.5" FIT — EASY SWAP: Fits most standard 10" x 2.5" reverse osmosis, under-sink, and two-stage whole-house housings. Rated to 2.5 GPM and 100 psi; plan on roughly 3–6 months (~2,500 gallons) per set depending on your water quality. Replaces in minutes — backed by US-based CFS support.
