Tier1 5 Micron 10 x 4.5 Water Filter | Radial Flow Carbon Block Whole House Water Filter Cartridge Kit with O-Ring & Lubricant | Replacement for Pentek EP-BB, EP5-BB, 155548-43 | 4.5 x 10 Water Filter

Q. What is this filter used for? A. This whole house cartridge is designed to help reduce iron and manganese in water at the point of entry, supporting better water quality across sinks, showers, toilets, and appliances. Q. How does cation exchange resin reduce iron and manganese? A. Ion exchange resin contains charged beads that exchange ions with dissolved minerals in water, capturing iron and manganese ions as water flows through the cartridge. Q. Where is this filter typically installed? A. This 20 x 4.5 inch cartridge is typically installed in a whole house housing at the main water line, often located in a basement, garage, utility area, or well house. Q. Should I use a sediment filter with it? A. Yes. A sediment pre-filter is commonly recommended upstream to help reduce particulate loading and improve overall cartridge life in real-world systems. Q. Will this help with iron staining? A. It’s designed to help reduce iron and manganese that are often linked with staining issues; results depend on water chemistry and mineral levels. Q. How do I know when to replace it? A. Replacement timing depends on usage and water conditions. Common signs include the return of staining, reduced flow, or reduced performance compared to earlier use. Q. Do I need salt or regeneration? A. Many whole house iron/manganese solutions using ion exchange are regenerated with salt, but replacement cartridges are typically used as change-out media instead of regeneration cycles.

• COMPATIBLE REPLACEMENT MODELS – This 5 Micron 10 x 4.5 carbon water filter is a replacement for Pentair EP-BB, EP5-BB, 155548-43, CG5-104, EV910805, EP5-10BB, 155548, CB-45-1005, ClearChoice 84629, DuPont WFHDC8001, Liquatec CB-450-975-05, 4PCD1 and fits most 10 inch water filter housings.
• 5 MICRON CARBON BLOCK FILTRATION – Radial flow carbon block media helps reduce chlorine taste and odor while capturing fine sediment such as rust, dirt, and particulate commonly present in municipal water supplies before it reaches plumbing fixtures and appliances.
• RADIAL FLOW CARBON MEDIA DESIGN – Radial flow construction directs water from the outer surface toward the center core, supporting consistent contact with the compressed carbon media for balanced taste and odor reduction across the home.
• BEST USED AFTER A SEDIMENT PRE-FILTER – Commonly installed after a sediment filtration stage to help reduce particulate loading while allowing the 5 micron radial flow carbon block to focus on chlorine taste and odor reduction across the home.
• SERVICE LIFE VARIES BY WATER CONDITIONS – Replacement timing depends on iron/manganese levels and household usage; return of staining, reduced flow, or performance drop are common indicators to change the cartridge.
