This 1/4 cubic foot cation resin media can be used on its own or combined with additional resin as needed, making it a flexible choice for restoring softening performance across a wide range of water softener tanks. - πŸ’§ Efficient Water Softening – Made with 100% ion exchange premium resin, the MED-CAT-025 is designed to soften hard water by exchanging calcium and magnesium hardness ions. This helps restore your water softener’s ability to reduce hardness, improve water feel, and support better performance from plumbing, fixtures, appliances, laundry, and cleaning products. - πŸ’§ NSF/ANSI 44 Certified Quality – NSF/ANSI 44 certified and built with FDA-approved materials for added confidence in quality, safety, and performance. This premium cation resin media is made to meet strict water softening standards, giving you confidence that the resin you receive is clean, dependable, and built for long-lasting ion exchange performance. - πŸ’§ Helps Reduce Hard Water Problems – Helps reduce hardness minerals that can contribute to scale buildup, soap scum, spotting, poor lather, and mineral deposits on fixtures and appliances. Softer water can help improve everyday washing, bathing, laundry, dishwashing, cleaning, and overall water use throughout the home, RV, or business. - πŸ’§ Restores Softener Performance – Refresh your water softener resin bed when existing resin is exhausted, fouled, or no longer producing the soft water results you expect. Replacing old resin can help restore softening efficiency, improve regeneration performance, and extend the useful life of your water softener system. - πŸ’§ Easy-Pour 1/4 Cubic Foot Size – Packaged for convenient handling during resin replacement, refill, or system maintenance. The 0.25 cubic foot quantity is easy to pour, easy to measure, and simple to combine with additional resin when larger tank refills are needed. - πŸ’§ Important TDS Notice – This water softener resin is designed to reduce hardness minerals through ion exchange, but it does not reduce total dissolved solids. TDS reduction typically requires reverse osmosis filtration and should not be expected from standard cation softening resin. - πŸ’§ Lifetime Technical Support – Your satisfaction is important to us. Every iFilters filter is backed by knowledgeable USA-based lifetime technical support. Whether you need help confirming compatibility, installing your filter, troubleshooting performance, or choosing the right replacement media, our team is here to help before and after your purchase. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B079P7QCJF | | Best Sellers Rank | #43,218 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #28 in Water Softeners | | Color | Brown | | Customer Reviews | 4.4 4.4 out of 5 stars (720) | | Date First Available | February 8, 2018 | | Item Package Quantity | 1 | | Item Weight | 11.9 pounds | | Item model number | FBA-MED-CAT-025 | | Manufacturer | iFilters | | Material | Softener Resin | | Part Number | FBA-MED-CAT-025 | | Product Dimensions | 12 x 12 x 6 inches | | Style | 1/4 Cubic Foot | ## Images ![Water Softener Resin Media Replacement, 1/4 Cu Ft Cation Resin, 8,000 Grain | MED-CAT-025 | 1/4 Cu Ft Ion Exchange Cation Resin | Water Softener Media for Home, RV & Portable Systems - Image 1](https://m.media-amazon.com/images/I/915Unie-YSL.jpg) ![Water Softener Resin Media Replacement, 1/4 Cu Ft Cation Resin, 8,000 Grain | MED-CAT-025 | 1/4 Cu Ft Ion Exchange Cation Resin | Water Softener Media for Home, RV & Portable Systems - Image 2](https://m.media-amazon.com/images/I/811NKfILnAL.jpg) ![Water Softener Resin Media Replacement, 1/4 Cu Ft Cation Resin, 8,000 Grain | MED-CAT-025 | 1/4 Cu Ft Ion Exchange Cation Resin | Water Softener Media for Home, RV & Portable Systems - Image 3](https://m.media-amazon.com/images/I/81+cSRdJ+wL.jpg) ![Water Softener Resin Media Replacement, 1/4 Cu Ft Cation Resin, 8,000 Grain | MED-CAT-025 | 1/4 Cu Ft Ion Exchange Cation Resin | Water Softener Media for Home, RV & Portable Systems - Image 4](https://m.media-amazon.com/images/I/71wz5yg8jSL.jpg) ![Water Softener Resin Media Replacement, 1/4 Cu Ft Cation Resin, 8,000 Grain | MED-CAT-025 | 1/4 Cu Ft Ion Exchange Cation Resin | Water Softener Media for Home, RV & Portable Systems - Image 5](https://m.media-amazon.com/images/I/91pd4nstU-L.jpg) ## Available Options This product comes in different **Style** options. ## Frequently Bought Together - iFilters Resin Media Replacement for Water Softeners - 0.25 / ΒΌ Cubic Foot (CuFt) | 100% Ion Exchange Quality Cation | 8,000 Grain Capacity | Certified (MED-CAT-025) - American Water Solutions Multi Purpose Filling Funnel 2.5" x 10" - American Water Solutions Water Softener Gravel - Filter Bed Media for Filter Tanks, Water Conditioners, and Water Softeners - Pure Filtration Grade Bedding Perfect for Backwashing Tanks (15 Lbs) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/68556293-water-softener-resin-media-replacement-1-4-cu-ft-cation](https://www.desertcart.kr/products/68556293-water-softener-resin-media-replacement-1-4-cu-ft-cation) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-08-01*
