High-Capacity Quick-Connect Inline Water Filter (WD-G4-2512-JG)
The WD-G4-2512-JG is the highest-capacity quick connect water filter in our inline lineup, built for larger households or anyone who’d rather swap a cartridge less often without giving up any of the contaminant reduction Gen4 Advanced media provides. Found that our standard inline filter needs replacing more often than you’d like? This is the model we’d suggest stepping up to.
How the Connection Works
Like every filter in our JG line, this system uses John Guest water filter quick connect fittings that push directly onto your existing quarter-inch water line, with no tools, no thread tape, and no drilling required. The larger cartridge housing adds a bit of length to the install, but the connection process itself is identical to our standard-capacity inline filters – push, click, and you’re filtering water.
More Capacity, Fewer Swaps
The larger cartridge in this model extends the time between replacements substantially compared to our compact WD-G4-210-JG, which is the trade-off worth understanding when choosing between the two: a bit more upfront housing size in exchange for meaningfully longer intervals between cartridge changes. As an inline water filter quick connect option, it’s the better fit for households pushing higher daily water volume through their fridge or ice maker.
Where It Installs
This filter fits the same quarter-inch water lines as our other JG products – refrigerators, standalone ice makers, and RV water systems – so moving from our compact model to this quick connect inline water filter doesn’t call for different fittings or a different install process, just a larger housing in the same spot.

Frequently Asked Questions
How is this different from Woder’s standard inline filter?
The WD-G4-2512-JG uses a larger cartridge than our compact WD-G4-210-JG model, extending the time between replacements while using the same Gen4 Advanced filtration media and John Guest quick-connect fittings.
How long does the cartridge last?
This high-capacity cartridge is rated for meaningfully longer service life than our compact model – check the current spec sheet for the exact rated capacity based on typical household usage.
Is this a quick-connect (tool-free) installation?
Yes – it uses the same John Guest push-to-connect fittings as our other inline filters, so no tools, thread tape, or drilling are required.
