Key Features

• COMPATIBLE REPLACEMENT MODELS – This 0.5 micron 10 x 4.5 sediment water filter is a replacement for Pentair 355212-43 and WP.5BB97P; fits most standard 10 inch x 4.5 inch whole house filter housings.
• 0.5 MICRON FINE SEDIMENT FILTRATION – Designed to capture ultra-fine sediment, rust fines, silt, and microscopic particulate matter commonly present in treated municipal water or properly pre-filtered well systems.
• STRING WOUND POLYPROPYLENE MEDIA DESIGN – Tightly wound polypropylene fibers create structured depth filtration that distributes fine sediment throughout the cartridge, supporting controlled flow in polishing-stage applications
• IDEAL FOR FINE SEDIMENT CONTROL – Designed for whole house systems requiring enhanced particulate reduction in treated municipal water or controlled sediment environments
• SERVICE LIFE VARIES BY WATER CONDITIONS – Finer micron cartridges capture smaller particles more quickly; monitoring pressure or flow changes helps determine replacement timing based on sediment load and system configuration.
