About This
- Compatible With All Woder G4 Systems: Fits Gen4 mounting heads in WD-G4-DC under sink water filter and WD-G4-JG inline water filter systems, and as the 2nd, final stage in every WD-D-FRM-G4, WD-D-HMG4, and WD-D-20M-G4 dual-stage system.
- Advanced Heavy Metal & Contaminant Removal: This cartridge for your drinking water filter removes 99.9% of lead, mercury, chromium-6, PFAS, VOCs, THMs, glyphosate, and chlorine taste and odor, independently tested by CLB Labs.
- Keeps Essential Minerals: Unlike reverse osmosis, this water filtration cartridge preserves beneficial calcium and magnesium while removing harmful contaminants. No water waste, no pump, no storage tank required.
- Tool-Free Replacement, No Mess: The auto shut-off valve stops water flow automatically during the cartridge swap. Twist out the used cartridge, twist in the WD-G4-L, flush for 3 minutes, and you are ready to go.
- WQA Certified, Independently Tested: This water filter system cartridge is certified to NSF/ANSI 42 for chlorine taste and odor reduction and NSF/ANSI 372 for lead-free compliance, additionally tested by CLB Labs.
- 1-Year Cartridge Warranty: Every WD-G4-L cartridge for your drinking water filter is covered by a full year representing its rated lifespan and filtration capacity. Replace when flow decreases or taste returns.
