<p>The Pentek PCC Series filter cartridge protects water-using equipment from scale, corrosion, and iron buildup using food-grade hexametaphosphate media. As water passes through the cartridge, the hexametaphosphate slowly dissolves and coats interior surfaces, inhibiting the formation of scale and rust for effective, low-maintenance protection.</p> <p>Unlike sediment or carbon cartridges that filter out contaminants, the PCC Series works through controlled-release water treatment - making it an ideal solution for equipment vulnerable to hard-water scale and corrosion damage. It's commonly used to protect ice machines, coffee and vending machines, foodservice equipment, water heaters, air conditioning systems, and other water-processing equipment where scale buildup can shorten equipment life and increase maintenance costs.</p> <p>The PCC Series is rated for up to six months of protection, depending on flow rate and feed concentration, offering a cost-effective way to extend the service life of water-using appliances and systems.</p> <p>Key Features:<br>- Scale and corrosion inhibitor cartridge using hexametaphosphate media<br>- Protects against scale, corrosion, and iron buildup<br>- Ideal for ice machines, coffee/vending equipment, foodservice equipment, water heaters, and HVAC systems<br>- Effective for up to 6 months depending on flow rate and feed concentration<br>- Simple drop-in replacement for compatible cartridge housings<br>- Low-maintenance, passive protection - no electricity or backwashing required</p> <p>Specifications:<br>Brand: Pentair<br>Product Line: Pentek PCC Series<br>Media Type: Hexametaphosphate (scale/corrosion inhibitor)<br>Function: Scale, corrosion, and iron control (controlled-release treatment, not mechanical filtration)<br>Rated Service Life: Up to 6 months (flow rate and feed concentration dependent)<br>Typical Applications: Ice machines, coffee/vending machines, foodservice equipment, water heaters, air conditioning equipment, general water-processing equipment</p>

Built with a bed of granular activated carbon (GAC) sandwiched between a durable spun polypropylene core and a 70-micron porous polyethylene outer shell, both cartridges in the series use a radial flow design that channels water evenly through the full carbon bed &mdash; delivering the benefits of GAC filtration in a high-flow, point-of-entry format.</p> <p>This radial flow construction significantly reduces the carbon fines commonly released by conventional GAC-style cartridges, meaning cleaner-running water without the black carbon dust often seen after installing standard granular carbon filters. Both models are tested and certified by NSF International to NSF/ANSI Standard 42 for material requirements, and pair well as a carbon stage alongside sediment or iron-reduction pre-filters in a multi-stage whole house system.</p> <p>Select the model below that matches your Big Blue housing size &mdash; the RFC-BB for standard 10" systems, or the RFC20-BB for larger households and higher water-demand systems needing greater flow and capacity.</p>

Both cartridges in the series use a radial flow design that channels water through the full iron-reduction media bed, effectively reducing up to 3 PPM of dissolved iron while adding no harmful chemicals &mdash; making them safe for drinking water applications.</p> <p>Beyond taste and staining, reducing dissolved iron also protects pipes and water heaters from long-term damage, extending the life of your home's plumbing and water-using appliances. The RFFE10-BB and RFFE20-BB should be installed on the main cold water line after the pressure tank or water meter, and for best results, Pentair recommends pairing either cartridge with pre-sediment filtration and post-carbon treatment (commonly an RFC-BB or RFC20-BB carbon cartridge) as part of a complete whole house system.</p> <p>Select the model below that matches your Big Blue housing size &mdash; the RFFE10-BB for smaller households or compact systems, and the RFFE20-BB for larger households or higher water-demand systems.</p>

These modified molded blocks are built using Pentek's proprietary Fibredyne technology, which attaches powdered activated carbon onto a cellulose-free synthetic fiber matrix &mdash; combining the benefits of a sediment filter and a carbon block in a single cartridge.</p> <p>Fibredyne's carbon block technology delivers up to two times the chlorine taste and odor reduction and dirt-holding capacity of traditional carbon blocks, while a unique post-filtration layer fused to the carbon/fiber media blend prevents carbon fines from releasing into the effluent stream. This makes the CFB-Plus Series an ideal choice for a wide range of residential, food service, commercial, and industrial applications requiring premium taste, odor, and sediment reduction.</p> <p>Available from a compact 9.75" cartridge up to a full 20" Big Blue format, the CFB-Plus Series scales from point-of-use under-sink systems to whole house filtration.

This 10" combination cartridge pairs coconut shell granular activated carbon (GAC) with calcite media, making it ideal for correcting low pH levels, polishing filtered water, and improving the taste of coffee, tea, and other beverages made with RO water.</p> <p>As calcite dissolves gradually in acidic water, it naturally raises pH toward neutral, counteracting the slightly acidic output common to many RO systems, while the coconut shell carbon component helps reduce sediment, bad taste, odor, and residual chlorine as a final post-filter stage. Designed for easy installation, the GS-10CAL/RO-B is compatible with most reverse osmosis and under-sink water filtration systems.</p> <p>With a typical filter life of approximately 3&ndash;6 months (depending on water quality and usage), the GS-10CAL/RO-B is a simple, effective add-on for anyone looking to fine-tune their RO system's final water quality and taste.</p>
