About This
- 💧 Under Sink Drinking Water Filtration – This iFilters under sink drinking water system combines 3-stage carbon block filtration for 20X more effective and longer lasting drinking water than the leading water pitcher dispensers. Ideal for city and well water, this 3-stage under sink system helps reduce sediment, chlorine taste and odor, iron, certain heavy metals, and fine contaminants for cleaner, fresher-tasting water.
- 💧 Stage 2: KDF/GAC Filtration – The second stage uses KDF05-10 media with granular activated carbon to target city and well water concerns. KDF helps reduce iron, chlorine taste and odor, and certain water-soluble heavy metals, while GAC helps reduce bad taste, odor, and common contaminants for cleaner, better-tasting drinking water.
- 💧 Stage 3: 0.5 Micron Coconut Carbon Block – The final CBSM-2510 carbon block provides finer filtration than standard 1, 5, or 10 micron drinking water filters. Its dense 0.5 micron structure is designed to help reduce fine sediment, dirt, rust, sand, and suspended particles that larger-micron filters may allow through.
- 💧 Built-In Shok Blok Pressure Regulator – Includes a Shok Blok pressure regulator designed to help control incoming water pressure before it reaches the filtration system. By reducing pressure spikes and stress on housings, fittings, seals, and cartridges, the Shok Blok helps reduce cracking, leaking, and premature wear while supporting longer filter life and more consistent performance between replacements.
- 💧 Replacement Filter Compatibility – Designed for use with the iFilters IFD-U3PK replacement filter set. This set includes the sediment filter, KDF/GAC filter, and CBSM-2510 0.5 micron carbon block filter needed to help maintain proper system performance, fit, flow, and drinking water filtration results. For best results, replace the filters every 6-12 months or 2,000 gallons.
- 💧 Important TDS Notice – This under sink carbon block drinking water system does not reduce total dissolved solids, which means naturally occurring dissolved minerals remain in the water. TDS reduction typically requires reverse osmosis filtration.
- 💧 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 cartridge, our team is here to help before and after your purchase.
