Tier1 25 Micron 10 x 2.5 Water Filter | Radial Flow Carbon Block Whole House Water Filter Cartridge | Replacement for Pentek RFC-93, SDP-2510 | 2.5 x 10 Water Filter

Q. What is this filter used for? A. This whole house carbon block water filter is designed to help reduce chlorine taste and odor while also capturing coarse sediment such as sand, dirt, rust particles, and debris before water reaches household plumbing and fixtures. Q. What does 25 micron filtration do best? A. A 25 micron rating targets larger visible sediment, allowing strong water flow while supporting coarse particulate capture in whole house filtration systems. Q. How does carbon block filtration work? A. Carbon block filters use compressed activated carbon to reduce chlorine through adsorption while also acting as a mechanical barrier for sediment particles. Q. Where is this filter typically installed? A. The 10 x 2.5 inch cartridge size is commonly installed in slimline whole house housings at the main water line or in dedicated carbon filtration stages. Q. Is this compatible with specific replacement models? A. Yes. This cartridge is compatible with systems designed for Pentek RFC-93 and SDP-2510 style 10” x 2.5” housings that match the listed cartridge size. Q. Is this suitable for municipal or well water? A. This filter is commonly used with treated municipal water where chlorine is present. In well water systems, sediment pre-filtration may be recommended when sediment levels are elevated. Q. How do I know when to replace it? A. Replacement timing varies based on chlorine levels, sediment conditions, and household usage. Monitoring pressure drop or reduced flow helps indicate when replacement may be needed.
