About This
- Fits Under Sink, Fridge, Ice Maker & RV Setups: This under sink water filter system installs anywhere 1/4in JG tubing runs, a great alternative to short-lived OEM refrigerator filters, feeding a faucet, fridge, ice maker, or RV line.
- Advanced Heavy Metal & Contaminant Removal: Combines Gen4 filtration with additional heavy metal media, removing 99.9% of lead, mercury, chromium-6, PFAS, VOCs, THMs, glyphosate, and chlorine, ideal for water filters for sink or appliance use.
- Keeps Essential Minerals: Unlike reverse osmosis, this water filter under sink preserves beneficial calcium and magnesium while removing harmful contaminants. No water waste, no pump, no storage tank required.
- Easy DIY Install: Welded-in 1/4in John Guest quick connect fittings on both sides make this water filtration setup fit all 1/4in plastic flex or copper tubing. No plumber, no drilling, no permanent changes.
- WQA Certified, Independently Tested: This under sink water filter 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.
- Up to 10,000 Gallons, 1-Year Warranty: Every WD-G4-2512 cartridge is rated for up to 10,000 gallons over about 3 years of typical use, cutting long-term cost versus bottled water or frequent OEM fridge filter swaps.
