Product Details
✓[High-Quality KDF Filter] KDF (Kinetic Degradation Fluxion) filters, via redox reactions and catalytic processes, converts harmful substances in water into harmless compounds. It also removes residual chlorine, improving the taste and odor of the water.
✓[Optimal Filtration Efficiency] SimPure's GAC/KDF filters use an optimal blend of coconut shell activated carbon granules and high-purity copper-zinc alloys as the primary filtering materials. This ensures maximum removal of iron, lead, mercury, residual chlorine, and odors.
✓[Longer Lifespan] To achieve optimum performance, we suggest replacing the KDF water filter cartridge every 6-12 months depending on your water quality. For best results and to extend product lifespan, we recommend a water pressure of 25-90 psi and a temperature range of 41-100°F.
✓[Universal 20-in BB Filter Cartridge] In addition to being the original replacement filter for SimPure DB20P-3KDF, DB20P-3, and DB20P housings, it is also compatible with most 10x4.5 inch whole house water filters and housings including but not limited to WGB32B, WGB22B WGB12B, HB28B, Geek-Pure BB-20T, BB-20B, 150233, 166201, etc. Rubber washers on both ends ensure a tight seal.
✓[Note] The filter is not fully filled to ensure optimal filter performance. This allows sufficient space to prevents pressure drop, and maintains efficient water flow through the media. Additionally, this filter is not designed for media replacement.
