Key Features

• COMPATIBLE REPLACEMENT MODELS – This 5 micron 10 x 4.5 carbon block cartridge is a replacement for Pentek EP-BB, EP5-BB, 155548-43, CG5-104, EV910805 and is compatible with systems using GE FXHSC, Culligan R50-BBSA, Pentek R50-BB, DuPont WFHDC3001, W50PEHD, GXWH40L, HD-950, American Plumber W50PEHD, GXWH35F, GXWH38F, GXWH30C, GNQH38S, WHKF-WHPLBB, and similar 4.5” x 10” whole house water filter housings.
• 5 MICRON CARBON BLOCK FILTRATION – Designed to reduce chlorine taste and odor while capturing fine sediment, rust, and particulate matter, supporting improved water clarity and more consistent household water quality.
• CARBON BLOCK MEDIA DESIGN – Dense carbon block construction combines mechanical sediment filtration with adsorption technology, helping reduce chlorine while supporting stable flow in municipal water systems.
• IDEAL WHOLE HOUSE TREATMENT STAGE – Commonly installed at the main water entry point to help protect plumbing, fixtures, appliances, and downstream filtration equipment from sediment and chlorine exposure.
• SERVICE LIFE VARIES BY WATER CONDITIONS – Replacement frequency depends on chlorine levels, sediment loads, water quality, and micron rating; many households replace 5 micron whole house sediment filters around six months to maintain steady flow and consistent system performance
