Removal Capabilities: Our advanced PFAS water filter removes 99.9% of lead, heavy metals, chlorine, and PFAS. This is in addition to chromium 6, mercury, volatile organic compounds, carcinogens, and other contaminants removal. It also remove turbidity, odors, and bad tastes (claims tested by CLB Labs and are not certified by WQA).

Product Dimensions
15.4″ X 3.6″ (7″ space needed with the hoses) X 2.52″

Cartridge lifespan: 1 year under warranty.

System includes: WD-G4-REP cartridge, head with a built-in shut off valve, inlet hose (3/8″ female compression by 1/4″ standard pipe thread), outlet hose (3/8″ compression by 1/4″ standard pipe).

Selective Filtration™
Our proprietary Selective Filtration™ technology removes 99.9% of contaminants while leaving in all essential minerals. Reverse Osmosis (RO) filters also remove 99.9% of contaminants, however, RO also remove ALL the minerals found in tap water.  This include minerals your body needs. RO systems can waste thousands of gallons of water annually while flushing contaminants down the drain.

Preventing Sediment Buildup
If your water supply contains elevated levels of sediment, a dual-stage Sediment Removal Filter System is recommended to prevent decreased filter life. This is due to particulate buildup within the filter. Rust from old plumbing, upstream construction contributing to excess sediment finding its way into your water supply. Water supplies with high levels of sand and contaminants can all result in water conditions not suitable for a single-stage filter system.

PFAS, Lead & Chlorine Removal Water Filter (WD-G4-DC)

The WD-G4-DC is our flagship pfas water filter, and it’s the single-stage Gen4 Advanced system most households land on when they want broad, reliable contaminant reduction without a multi-cartridge setup. It connects directly to your under-sink cold-water valve and reduces PFAS, lead, and chlorine, along with a range of other common contaminants, while keeping the minerals your water is supposed to have in it. As a water filter for pfas reduction, this is our most-purchased single product.

PFAS and Why It Matters

PFAS, sometimes called “forever chemicals” because they don’t break down easily in the environment, have become a growing concern in municipal water testing across the country. If you’re researching what water filter removes pfas effectively, EPA guidance has increasingly focused on these compounds precisely because they’re persistent and linked to health concerns at even low concentrations. A pfas filter for water, or what some people search for as a water filter pfas solution, that specifically targets these compounds, rather than incidentally catching a fraction of them, is the more reliable approach if PFAS shows up in your local water report.

This is where third-party verification matters. The WD-G4-DC’s Gen4 Advanced media carries WQA Gold Seal certification, meaning independent testing has confirmed the removal claims rather than us simply stating them. If you’re comparing options and looking for a pfas certified water filter, that certification is the difference between a marketing claim and a verified one, and it’s a big part of why we consider this the best water filter to remove pfas in our own lineup.

Certification, Selective Filtration, and Installation

Selective Filtration is the technology behind all of this, and it’s fundamentally different from how reverse osmosis works. RO forces water through a membrane that strips out nearly everything, contaminants and minerals together, while producing a meaningful amount of wastewater along the way. Our media targets PFAS, lead, chlorine, and chromium-6 specifically, so the water filter removes pfas without also stripping calcium and magnesium out of your water. As a pfas removing water filter goes, that mineral retention is the core differentiator.

Installation is direct-connect to your existing faucet’s cold-water valve, no drilling required, and it’s widely available through our site if you’re searching for a pfas water filter near me rather than waiting on local stock. This model is also the recommended replacement for our discontinued WD-S-8K-ADV-DC, so if you’re upgrading from that older system, this is the direct successor. Any water pfas filter comparison should account for both the certification and the mineral-retention approach together, not just the removal percentage on its own. This filter is designed and packaged in the USA. This filter belongs to our Advanced Filtration (Under-Sink) lineup, and replacement cartridges are available in our Replacement Cartridges category.

Frequently Asked Questions

Does this filter really remove PFAS?

Yes, Gen4 Advanced Selective Filtration media is specifically engineered to reduce PFAS, and that removal capability is backed by WQA Gold Seal certification rather than just an unverified claim.

Is the WD-G4-DC WQA certified?

Yes, the Gen4 Advanced media used in this filter carries WQA Gold Seal certification, an independent third-party verification of its contaminant reduction performance.

How is this different from the discontinued WD-S-8K-ADV-DC?

The WD-G4-DC is the direct successor and recommended upgrade path, using our current Gen4 Advanced media in the same direct-connect housing style.

How is this filter installed?

It direct-connects to your existing under-sink cold-water valve, no drilling required, following the same install process as the rest of our Direct Connect lineup.

What else does this filter remove besides PFAS?

It also reduces lead, chlorine, chromium-6, and other common contaminants, all while retaining beneficial minerals like calcium and magnesium through Selective Filtration.
