Fluoride Removal Prefilter
A powerful companion to the UltraStream, Higen1+ or the Higen2+ designed to dramatically reduce fluoride in your drinking water.
Dual Stage Fluoride Removal
Our UltraStream filter, alone removes around 80% of fluoride
Fluoride Pre-Filter alone removes around 80-90% fluoride
Combined, they achieve up to 95%–99% fluoride reduction for truly clean, safe water
How It Works: Activated Alumina Technology
This pre-filter uses Activated Alumina, a high-surface-area material made from aluminium oxide (Al₂O₃), the same base mineral found in sapphires and rubies.
It’s created through a special process that makes it highly porous—over 200 m² of surface area per gram.
This surface area makes it highly effective at adsorbing fluoride and arsenic from drinking water.
Is Activated Alumina Safe?
Activated alumina is made from aluminum oxide (Al₂O₃), the same stable compound found in sapphires and rubies. It’s chemically inert and does not dissolve or release aluminum into the water.
The aluminum in activated alumina is tightly bound in its oxide form and does not exist as free or reactive aluminum, which is the form associated with health concerns.
Numerous studies and industry safety standards (including NSF/ANSI 61 for drinking water components) confirm that properly manufactured activated alumina is safe and does not pose a risk of aluminum leaching.
- Additionally, any potential trace residues are effectively captured by a secondary filtration stage—such as KDF media or carbon—as featured in the UltraStream system
great for adding that extra % of fluride protection
