PUREPLUS 1 Micron 2.5" x 10" Whole House CTO Carbon Water Filter Cartridge Replacement 3PACK and 5 Micron 10" x 2.5" Whole House Grooved Sediment Home Water Filter 6PACK

The PUREPLUS Water Filter Combo pairs the CTO10 carbon filter (NSF-certified for chlorine/odor reduction) with the PP10GD grooved sediment filter for complete tap water treatment. The CTO10 uses coconut shell activated carbon (13,000 gallon capacity), while the PP10GD features grooved triple-layer PP media (5/7/10μm). Both fit standard 10"x2.5" housings (3M, Culligan, GE compatible), last 30% longer than standard filters, and require replacement every 3-6 months. ISO-certified manufacturing with rigorous quality testing.

• 【Dual-Stage Certified Filtration System】The CTO10 carbon filter is NSF/ANSI 42 certified by IAPMO, effectively reducing 99% chlorine and improving water taste, while meeting European, Canadian CSA, and Australian Water Mark standards. The PP10GD sediment filter complements this with food-grade polypropylene material certified to EC1935-2004, REACH, and BPA-Free standards, creating a complete filtration solution for tap water treatment.
• 【Advanced Complementary Filtration Technologies】The PP10GD features a grooved three-layer PP design (5/7/10μm) that maximizes sediment removal efficiency, while the CTO10 utilizes 100% coconut shell activated carbon block with sintering technology that provides 125 acres of filtering surface area per pound. Together they deliver 30% longer service life than conventional filters, with both processing up to 13,000 gallons depending on water quality.
• 【Optimized Performance for Cleaner Water】This combination provides comprehensive water treatment: the PP10GD's grooved design effectively captures particles and sediments, while the CTO10's high-quality carbon block removes chlorine, odors, and improves taste. Both maintain excellent flow rates and are recommended for replacement every 3-6 months for optimal performance in average households.
• 【Wide Compatibility with Major Filtration Systems】Both filters fit standard 10"x2.5" housings and are compatible with leading brands including 3M (AP110, AP11T), Culligan (HF-150A, HF-360A), GE (GXWH20S, FXWTC), Dupont (WFPFC8002, WFPF13003B), and AO Smith systems. This universal fit makes them ideal replacements for most whole-house and under-sink RO filtration systems.
• 【PUREPLUS Quality Assurance & Industry Leadership】Manufactured under ISO9001 standards, each filter undergoes 34 rigorous production processes including 400PSI pressure tests and 10,000 water hammer cycles. Backed by 20 years of expertise and 200 patents in water filtration, PUREPLUS provides reliable solutions trusted by over 200 million households worldwide.
