What this filter does at your kitchen sink
- Your main faucet stays put, so you can still use unfiltered water for washing fruits and vegetables.
- The dedicated faucet is for drinking water, keeping the two jobs separate.
- Nothing about this system changes the water pressure or hot-water line you already have.
If you want better-tasting water straight from the tap without a pitcher hogging fridge space, this under-sink kit is worth a look. Three cartridges stack into an eight-stage flow, and the included faucet gives filtered water its own spout so your main tap stays free for rinsing produce.
We'd consider it for municipal tap water on a standard under-sink cold line, because that's the feed it's built around. The system doesn't lower TDS, the reading a handheld meter shows, since it leaves dissolved minerals like calcium and magnesium in the water. It filters out PFAS, PFOA and PFOS, residual chlorine, fluoride, heavy metals, silt, rust and cysts, and its fluoride resin reduces 97 percent of fluorides.

Room, water fit and filter planning
Set aside cabinet space under the sink plus room on the counter for the second faucet. The push-to-connect fittings work with 3/8 inch and 1/2 inch cold-water tubes, and the install is meant to be a DIY job rather than a plumber visit. Once it's running, the dedicated faucet puts out a max flow of 1.05 GPM.
Cartridge life splits across the year: roughly 6 months for one, 8 to 12 months for another and 12 to 18 for the third. Before buying, check the current prices of the WD-10PP, WD-10GC and WD-10CT replacements, since those are your ongoing cost. If your source is well water, confirm the feed has passed through pre-filtration first, and keep the system on cold water only.
When this is the wrong sink
This unit isn't for well water without pre-filtration or for hot water lines. And if a TDS reading is how you judge water quality, the minerals this system keeps will leave that number roughly where it started.
