Santevia Gravity Water System Fluoride Filter – 6-Stage Replacement Cartridge
The most comprehensive replacement filter for your Santevia Gravity Water System. This 6-stage cartridge removes up to 98% of fluoride, 99% of chlorine, plus lead, cadmium, microplastics, herbicides, pesticides, and pharmaceutical residues — while infusing your water with calcium, magnesium, potassium, and trace minerals to naturally raise the pH to alkaline levels.
Filter lifespan: 4 months or 1,200L (317 gallons) — twice the lifespan of standard pitcher filter cartridges. Made in Vancouver, British Columbia, Canada. HS Code: 842121.
Why This Filter Outperforms Standard Replacements
Most replacement filters use a single or dual-stage process. This cartridge uses six distinct filtration stages, each targeting a specific category of contaminant. Combined with the Gravity System's extended contact time — water moves slowly through each stage rather than rushing through a compact block — the result is measurably deeper purification across a broader contaminant spectrum than any standard pitcher filter replacement can achieve.
6-Stage Filtration Process
Stage 1 — Ceramic Pre-Filter
Physically blocks sediment, bacteria, and microplastic particles before water enters the chemical filtration stages. Ceramic filtration is effective against particles as small as 0.9 microns — well within the size range of microplastics detected in municipal tap water.
Stage 2 — Activated Carbon
Granulated activated carbon (GAC) reduces chlorine, chloramines, herbicides, pesticides, and volatile organic compounds (VOCs). The Gravity System's extended contact time allows the carbon to adsorb a significantly broader range of organic compounds than rapid-flow pitcher filters.
Stage 3 — Specialized Fluoride Reduction Media
A dedicated fluoride-reduction stage using specialized adsorption media achieves up to 98% fluoride removal — the performance level that requires extended contact time and a dedicated stage that standard pitcher filters cannot replicate.
Stage 4 — Ion Exchange Resin
Ion-exchange resin targets dissolved heavy metals (lead, cadmium) and pharmaceutical residues by swapping harmful ions for harmless ones. This stage provides the heavy metal and pharmaceutical protection that activated carbon alone cannot deliver.
Stage 5 — Mineral Stones
Far-infrared mineral stones infuse filtered water with calcium, magnesium, potassium, and trace minerals — the same mineral profile found in premium natural spring water. Rather than delivering stripped, flat-tasting filtered water, this stage actively rebuilds your water's mineral content.
Stage 6 — pH Enhancement
The final stage naturally raises the water's pH to alkaline levels through mineral chemistry — no artificial ionization, no electricity. Just natural mineral science producing smooth, balanced alkaline water.

Replacement Schedule
Replace every 4 months or after filtering 1,200 liters (317 gallons) — whichever comes first. For a two-person household drinking 4L per day, that's approximately one filter every 4 months. Regular replacement ensures consistent fluoride removal performance and optimal mineral output at every pour.
Perfect For
- Existing Santevia Gravity Water System owners due for a filter replacement
- Households on fluoridated municipal water supplies
- Families with children concerned about fluoride exposure
- Individuals with thyroid concerns or fluoride sensitivities
- Anyone wanting the broadest possible contaminant coverage from their Gravity System
Frequently Asked Questions
How much fluoride does the Santevia Gravity System Fluoride Filter remove?
The filter removes up to 98% of fluoride using a dedicated Stage 3 adsorption media. This level of fluoride reduction requires the extended contact time that the Gravity System's gravity-fed design provides — it cannot be replicated by standard rapid-flow pitcher filters.
How long does the Santevia Gravity Fluoride Filter last?
The filter has a 4-month lifespan or 1,200 liters (317 gallons) of filtered water, whichever comes first. For a two-person household drinking 4L per day, this works out to approximately one replacement every 4 months.
Is this filter compatible with all Santevia Gravity Water Systems?
Yes — the fluoride filter is compatible with Santevia Gravity Water System countertop and dispenser models. It is not compatible with the Santevia MINA Pitcher or other Santevia product lines.
Does this filter remove microplastics?
Yes. Stage 1 is a ceramic pre-filter that physically blocks particles as small as 0.9 microns, including microplastic particles increasingly detected in municipal tap water supplies.
Does this filter remove pharmaceutical residues?
Yes. Stage 4 ion-exchange resin reduces pharmaceutical residues alongside heavy metals such as lead and cadmium. Pharmaceutical contamination in tap water is an emerging concern in many North American water systems.
Does the filter make water alkaline?
Yes. Stage 6 naturally raises the water's pH to alkaline levels through mineral chemistry — no electricity or artificial ionization required. Stage 5 mineral stones also infuse calcium, magnesium, and potassium, contributing to the alkaline mineral profile.
Where is the Santevia Gravity Fluoride Filter made?
Manufactured in Vancouver, British Columbia, Canada — the same facility that produces the Santevia Gravity Water System.
What is the difference between this filter and the standard Gravity System filter?
The standard Gravity System filter uses a 5-stage process covering ceramic pre-filtration, activated carbon, ion exchange, mineral stones, and pH enhancement. This fluoride filter adds a dedicated Stage 3 fluoride-reduction media, bringing the total to 6 stages and adding up to 98% fluoride removal. If your household is on fluoridated municipal water, this is the recommended replacement cartridge.
