Woder Fluoride Removal and Advanced Dual Filtration System

Municipally treated water supplies with elevated fluoride levels have been shown to potentially contribute to adverse health effects. Our dual-stage FRM Fluoride Removal system is engineered to remove up to 95% of fluoride contaminants.

WQA-Certified Woder Advanced filters are certified by WQA to NSF/ANSI 42 for Chlorine taste, odor and NSF/ANSI 372 for lead free compliance as verified and substantiated by test data.

It is a dual stage water filter with FRM and Gen4 Advanced filtration. It provides up to 95% fluoride removal (First stage) IN ADDITION to Woder’s G4 Advanced removal (Second stage).

Concerned about Fluoride?

Enjoy fluoride-free water with the Woder Fluoride Removal Filter. It liminate 95% of fluoride present in municipally treated water. It also eliminating lead (99.9%), heavy metals and chlorine (99.9%). In addition, it also removes chromium 6, mercury, volatile organic compounds, carcinogens, PFAS, contaminants, as well as turbidity, odors, and bad tastes.

Enjoy natural, healthy, spring-fresh water from the tap. (claims tested by CLB Labs and are not certified by WQA).

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, they also remove ALL the minerals found in tap water, including minerals your body needs. Worse, RO systems can waste thousands of gallons of water annually while flushing out contaminants down the drain.

Fluoride Removal Water Filter – Dual-Stage System (WD-D-FRM-G4-DC)

The WD-D-FRM-G4-DC pairs a dedicated fluoride-reduction media stage with standard Gen4 Advanced filtration in one direct-connect system. It’s built for households who’ve decided they want that one contaminant handled alongside the usual suspects, lead and chlorine, rather than as a separate project requiring a second unit under the cabinet, covering both jobs in a single cartridge stack so you’re not running two separate systems side by side or maintaining two different install schedules. Anyone dealing with excess fluoride in municipal tap water in their area, whether flagged by a local report or just general awareness of regional fluoridation levels, is the household this system was designed around.

Why Levels Matter

Municipal fluoridation is standard practice across most of the US, set at levels intended for dental health, and most people are entirely comfortable with that. Others want the option to reduce it, whether due to local levels running higher than average, personal preference, or specific fluoride health considerations a household member has raised. That gives households the choice to reduce it without requiring a switch to bottled alternatives or committing to a full RO system just to manage one substance. Among the options out there, this dual-stage filtration system stands out for handling the job as a dedicated stage rather than a side effect of some broader treatment method, and it does so while still reducing lead and chlorine the way any of our standard Gen4 systems would, making it a genuine contender for anyone weighing what the best fluoride water filter for their situation actually looks like.

Non-RO Removal vs Reverse Osmosis

This is where the comparison to reverse osmosis matters most. If you’ve been searching for the best water filter to remove fluoride, RO systems do reduce it, but they also strip out beneficial minerals and waste a meaningful amount of output in the process, typically several gallons for every gallon actually filtered. Our dual-stage design relies on non-RO fluoride reduction instead, targeting the one contaminant directly through dedicated media rather than forcing everything through a membrane, so the calcium and magnesium you’d otherwise lose stay right where they belong. For anyone comparing options side by side, that tradeoff is exactly what makes this one of the best water filter for fluoride removal choices available if RO’s downsides, wasted output and stripped minerals, are a dealbreaker for your household.

Installation

Installation is straightforward direct-connect faucet installation to your existing supply valve, no drilling required. As an under sink fluoride water filter, it fits the same Direct Connect approach as our other under-sink products, so if you’ve installed a Woder system before, this one won’t feel any different to set up. This DC model is specifically the under-sink option in this lineup, if you’re comparing it against the inline fluoride water filter version for a fridge or RV line instead, the WD-D-FRM-G4-JG is that equivalent, same dual-stage media, different connection style entirely. This system is designed and packaged in the USA.

Frequently Asked Questions

How much fluoride does this filter remove?

The dual-stage media is built to reduce it by up to 95% under typical conditions, alongside standard Gen4 Advanced reduction of lead and chlorine.

Do I need reverse osmosis to remove fluoride from my water?

No. This dual-stage system reduces it through dedicated media, without the wasted output or mineral stripping that comes with an RO membrane.

How is this installed under the sink?

It direct-connects to your existing cold-water valve, the same install approach as our other under-sink systems, with no drilling required.

Does this filter also remove chlorine and other contaminants?

Yes, the second stage is our standard Gen4 Advanced media, which reduces chlorine, lead, and other common contaminants alongside the dedicated reduction stage described above.
