Santevia Gravity Water System 5-Stage Filter – Replacement Cartridge
The standard replacement filter for your Santevia Gravity Water System — ideal for non-fluoridated water supplies. This 5-stage cartridge removes 99% of chlorine, plus lead, cadmium, copper, microplastics, herbicides, pesticides, pharmaceutical residues, and VOCs, while infusing your water with calcium, magnesium, potassium, and trace minerals to naturally raise the pH to alkaline levels.
Filter lifespan: 6 months or 1,800L (475 gallons) — the longest lifespan of any Santevia Gravity replacement cartridge. Made in Vancouver, British Columbia, Canada. HS Code: 842121.
Why Choose the 5-Stage Filter Over the Fluoride Filter?
The 5-Stage Filter and the Fluoride Filter both fit the Santevia Gravity Water System, but they serve different households:
-
5-Stage Filter (this product) — Best for households on non-fluoridated water. Longer 6-month lifespan (vs. 4 months), higher 1,800L capacity (vs. 1,200L), and lower cost per liter filtered. Covers chlorine, heavy metals, microplastics, pharmaceuticals, herbicides, and VOCs.
-
Fluoride Filter — Best for households on fluoridated municipal water. Adds a dedicated Stage 3 fluoride-reduction media for up to 98% fluoride removal, at a shorter 4-month / 1,200L lifespan.
Not sure if your water is fluoridated? Check your municipality’s annual water quality report — most are published online and list fluoride levels by district.
5-Stage Filtration Process
Stage 1 — Ceramic Pre-Filter (separate component)
The Gravity System’s ceramic outer shell physically blocks sediment, bacteria, and microplastic particles before water enters the cartridge stages. Effective against particles as small as 0.9 microns. The ceramic pre-filter is a separate component maintained independently of this cartridge.
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 — water moves slowly through each stage rather than rushing through a compact block — allows the carbon to adsorb a significantly broader range of organic compounds than rapid-flow pitcher filters.
Stage 3 — Ion Exchange Resin
Ion-exchange resin targets dissolved heavy metals (lead, cadmium, copper) and pharmaceutical residues by swapping harmful ions for harmless ones. This is the stage that provides heavy metal and pharmaceutical protection that activated carbon alone cannot deliver.
Stage 4 — Additional Carbon Filtration
A secondary activated carbon stage provides enhanced purification for any organic compounds that passed through Stage 2, ensuring comprehensive reduction of chloramines, VOCs, and residual organic contaminants before water reaches the mineral stage.
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. Smooth, balanced alkaline water at every pour.
What This Filter Removes
-
Chlorine — 99% — eliminates disinfectant taste, odor, and byproducts via Stage 2 activated carbon
-
Chloramines — reduces this persistent municipal disinfectant alternative via Stages 2 & 4
-
Lead & cadmium — heavy metal removal via Stage 3 ion-exchange resin
-
Copper — reduces excess copper leaching from household pipes and plumbing fixtures
-
Microplastics — physically blocked by the ceramic pre-filter (0.9-micron filtration)
-
Herbicides & pesticides — agricultural contaminant reduction via extended-contact activated carbon
-
Pharmaceutical residues — reduced via Stage 3 ion-exchange resin
-
VOCs — volatile organic compounds adsorbed across Stages 2 & 4
What This Filter Adds
-
Calcium — supports bone density, muscle contraction, and nerve signaling
-
Magnesium — essential for energy metabolism, electrolyte balance, and cardiovascular health
-
Potassium — supports fluid regulation, heart function, and blood pressure
-
Trace minerals — naturally occurring minerals that contribute to overall mineral balance and water taste
-
Alkaline pH — naturally elevated for smooth, balanced hydration

Replacement Schedule
Replace every 6 months or after filtering 1,800 liters (475 gallons) — whichever comes first. For a two-person household drinking 4L per day, that’s approximately one replacement every 6 months. The 5-Stage Filter’s longer lifespan makes it the most cost-effective Gravity System replacement cartridge for non-fluoridated water households.
Frequently Asked Questions
What is the difference between the Santevia Gravity 5-Stage Filter and the Fluoride Filter?
Both cartridges fit the Santevia Gravity Water System, but the 5-Stage Filter is designed for non-fluoridated water supplies. It has a longer 6-month / 1,800L lifespan and covers chlorine, heavy metals, microplastics, pharmaceuticals, herbicides, and VOCs. The Fluoride Filter adds a dedicated fluoride-reduction stage (up to 98% removal) but has a shorter 4-month / 1,200L lifespan. If your municipal water contains added fluoride, choose the Fluoride Filter.
How long does the Santevia Gravity 5-Stage Filter last?
6 months or 1,800 liters (475 gallons), whichever comes first. For a two-person household drinking 4L per day, this is approximately one replacement every 6 months — the longest lifespan of any Santevia Gravity replacement cartridge.
Does the 5-Stage Filter remove lead?
Yes. Stage 3 ion-exchange resin removes lead, cadmium, copper, and pharmaceutical residues by swapping harmful ions for harmless ones. This is the stage that provides heavy metal protection that activated carbon alone cannot deliver.
Does the 5-Stage Filter remove microplastics?
Yes. The Gravity System’s ceramic pre-filter (a separate component) physically blocks particles as small as 0.9 microns, including microplastic particles. The ceramic pre-filter is maintained independently of this cartridge.
Does the 5-Stage Filter make water alkaline?
Yes. Stage 5 mineral stones infuse water with calcium, magnesium, potassium, and trace minerals, and Stage 6 naturally raises the water’s pH to alkaline levels through mineral chemistry — no electricity or artificial ionization required.
Is the 5-Stage Filter compatible with all Santevia Gravity Water Systems?
Yes — compatible with Santevia Gravity Water System countertop and dispenser models. Not compatible with the Santevia MINA Pitcher or other Santevia product lines.
Does the 5-Stage Filter remove pharmaceuticals?
Yes. Stage 3 ion-exchange resin reduces pharmaceutical residues alongside heavy metals. This is one of the few countertop filter replacements that explicitly addresses pharmaceutical contamination in tap water.
Where is the Santevia Gravity 5-Stage Filter made?
Manufactured in Vancouver, British Columbia, Canada — the same facility that produces the Santevia Gravity Water System.
