Fluoride-Free Filter System
Fluoride Removal System for Town Water (2-Stage Underbench)
A complete system designed to reduce fluoride at your drinking tap, combining pre-filtration with a dedicated fluoride stage for more consistent performance.
Uses calcium-based filtration media, no activated alumina.
This 2-stage system is designed specifically for fluoridated municipal water, combining pre-filtration with targeted fluoride removal.
Unlike many fluoride filters that rely on activated alumina, this system uses a calcium-carbon phosphate media, helping maintain mineral balance while avoiding aluminium-based filtration materials.
Reduced Impurities
Stage 1 — Pre-Filtration. Reduces common upstream contaminants that affect water quality and filter performance:
- Chlorine
- Organic chemicals
- Heavy metals
- Taste and odour compounds
This stage helps protect the fluoride filter and improves overall system efficiency.
Stage 2 — Fluoride Filtration. Targets specific ions that are more difficult to remove:
- Fluoride (primary focus)
- Arsenic (tested under specific conditions)
This stage is designed for targeted removal, rather than broad-spectrum filtration.
Attainable Benefits
- Improved Water Clarity at the Tap
Reduces chlorine, odours, and other common contaminants that affect taste and smell. - Targeted Fluoride Reduction
Designed specifically for fluoridated town water, using a dedicated filtration stage. - Consistent Performance Through Staged Filtration
Pre-filtration helps reduce load on the fluoride media, improving stability over time. - No Water Waste
Unlike reverse osmosis systems, this system operates at normal flow rates without reject water. - Maintains Natural Mineral Presence
Does not strip all dissolved minerals from the water.
(Note: performance varies depending on water quality and usage conditions.)
How It Works
Water passes through two stages:
Stage 1 — Pre-Filtration
Removes chlorine, chemicals, and metals that can interfere with downstream filtration.
Stage 2 — Fluoride Filtration
The FluorEx media uses a calcium-based process to attract and exchange negatively charged ions such as fluoride.
This staged approach:
- improves efficiency
- extends filter lifespan
- supports more stable performance in real household conditions
Designed for treated municipal water supplies
- Not suitable for microbiologically unsafe water without disinfection
- High calcium (hard water) may reduce fluoride removal efficiency
- Flow rate affects performance (~1.8–1.9 L/min recommended)
All materials used are food-grade and suitable for drinking water applications.
Filter Lifespan & Replacement
Fluoride filter lifespan depends on fluoride concentration:
- ~1900L at 0.7 mg/L
- ~1140L at 1.2 mg/L
- ~570L at 2.2 mg/L
Performance gradually declines as the media is used.
We recommend replacing the fluoride cartridge once performance begins to drop to maintain consistent results.
Pre-filtration helps extend the lifespan of this stage.
Replacement filters are available separately.
Certifications

FluorEx Filter Specifications
Advanced Fluoride Filtration Media
- Calcium-carbon phosphate based filtration
- Designed to attract and exchange negatively charged ions such as fluoride
- Free from activated alumina (aluminium-based media)
Why This Matters
Many fluoride filters use activated alumina, which:
- relies on aluminium-based adsorption
- can require stricter operating conditions for optimal performance
This system uses an alternative mineral-based approach designed for practical household use at standard flow rates.
What It Targets
Primary:
- Fluoride
- Arsenic (tested under specific conditions)
Secondary (varies):
- Some heavy metals
- Some charged contaminants
Performance Notes
Tested using real municipal water at practical flow rates.
- Fluoride reduction to low levels depending on input concentration
- Performance varies based on:
water chemistry
flow rate
usage patterns

Installation
To get your system up and running perfectly, we recommend having it installed by a registered plumber. Need help finding a skilled installer? Check out our Dealers and Installers Page and select "installers," or reach out to us with any questions.
The placement of your filtration unit under the bench can be tailored to fit your home's specific setup.
Installation can take anywhere between 1 hr and up. Since every home is unique, we can't provide an exact timeframe.
Have any more questions or need further advice? Please don't hesitate to contact us. We're here to ensure that your installation process is as smooth and customized as possible.
This system comes with all the parts needed for installation, including T-line Diverter valve, 1/4": tubing, John guest connectors. We have also included some pH drops for you to check the pH level of your water. We recommend alkaline water (8-9.5pH) for optimal health
