PP Sediment Cartridge - W-F300

HK$0.00

Product Description

The W-F300 is a high-efficiency 10-inch string-wound sediment filter cartridge featuring a classic honeycomb structure that delivers outstanding dirt-holding capacity and extended service life. Its true depth-filtration design progressively traps larger particles on the outside and finer ones toward the core — perfect as the first-stage pre-filter in residential or light commercial water systems, protecting downstream carbon blocks, RO membranes, appliances and plumbing.

Size

Dimensions (L × W × H): 5cm × 3 cm ×3 cm Cotton
