Upgrade your home water experience with the SimPure 5-Micron CTO Cartridge, a compact yet capable solution designed to protect your entire plumbing system. Sized at 10 inches by 4.5 inches, this cartridge fits a wide range of standard housings and works quietly in the background to help improve water quality at every faucet and appliance. Built for reliability and everyday use, it blends premium materials with a practical design, offering filtration without intruding on your routine.

What makes this cartridge stand out

• Premium coconut-shell activated carbon block paired with two food-grade non-woven fabric wraps to prevent carbon particles from entering water.
• Independent testing confirms material suitability and performance in line with NSF/ANSI 42 standards.
• Effective reduction of tastes and odors, including sulfur smells, while maintaining a strong water flow for daily use.

• Long service life with a balance of filtration efficiency and water flux, rated up to 35,000 gallons.
• Universal 4.5 x 10 inch size fits most standard 10-inch whole-house housings (DB10P, DB10C, GE GXWH series, and more).
• Two-pack convenience combined with American-based support available for the life of the product.
• Suitable as a post-filter after sediment stages or for filtering well water or rainwater in a whole-house setup.

Compatibility, installation, and practical use

Designed for common 10-inch housings, this cartridge is a practical upgrade for households using filters like DB10P, DB10C-2, GE GXWH40L or GXWH35F. Its 5-micron rating offers a practical balance between filtration efficiency and flow rate, helping to protect downstream appliances and improve water quality without requiring complex changes to your setup. For best results, replace the cartridge every 3–6 months depending on water quality and usage, and pair it with a sediment pre-filter if your water contains higher sediment levels.

Real-life scenarios include protection of softeners and appliances, reduction of off-putting tastes and odors from chlorine, and refinement of water after initial filtration stages. The result is a more pleasant daily experience with fewer odors and clearer water, while keeping your existing filtration hardware intact.
