Woder WD-20M-L 20-Micron Sediment Removal Replacement Cartridge, Captures Sand, Dust, Dirt & Rust, Fits WD-20M & WD-D-20M-G4 Systems, 1-Year Warranty, Made in USA

If your home has high sediment levels, old pipes contributing rust and scale, or no whole-house pre-filtration system, sediment buildup can shorten your filter's lifespan and degrade performance over time. The WD-20M-L keeps your Woder system working at full capacity by replacing the dedicated 1st stage sediment removal cartridge before it reaches the end of its rated life.The WD-20M-L is the 1st stage replacement cartridge for WD-20M-DC and WD-20M-JG single-stage systems, and for WD-D-20M-G4-DC and WD-D-20M-G4-JG dual-stage systems. It must always be installed as the 1st stage. The 2nd and final stage uses the WD-G4-REP Advanced filtration cartridge, which removes 99.9% of lead, mercury, chromium-6, PFAS, VOCs, THMs, and chlorine while preserving calcium and magnesium. Together the two stages deliver 20-micron sediment removal plus full-spectrum contaminant filtration in a single compact system.Twist out the used cartridge, twist in the new WD-20M-L as the 1st stage, and flush for 3 minutes before use. The auto shut-off valve stops water flow automatically during the swap - no tools, no water mess, no plumbing changes required. Built in the USA in accordance with US building code. Use with municipally treated cold water only - do not run hot, softened, or untreated well water through the system.Every WD-20M-L cartridge is covered by a 1-year warranty representing its full rated lifespan - one cartridge, one full year of sediment-free water, guaranteed. Lifespan may vary depending on local water conditions, usage patterns, or municipal infrastructure. Replace when flow decreases noticeably or sediment becomes visible again. Replace the mounting head every 3-4 years for optimal performance.Woder was founded on a simple promise: make clean water affordable for everyone. Every WD-20M-L cartridge is built in the USA to keep your filtration system running cleanly and efficiently - one year at a time.
