While fluoride at optimal levels (0.7–1.2 ppm) helps prevent cavities, excessive exposure poses documented risks, from dental fluorosis and thyroid disruption to potential cognitive impacts. Many water sources contain unnaturally high fluoride levels (up to 14 ppm in some areas), leaving families vulnerable. That’s why precision filtration matters.

Our advanced media—like activated alumina and Ca-Fe-Al complex polymers—target fluoride selectively, reducing concentrations from 14 ppm to under 1 ppm while preserving essential minerals.

With lab-proven adsorption of 40 mg fluoride per gram, our filtration media delivers effortless protection, just cleaner water that safeguards long-term health. Whether you’re filtering city drinking water or well water, our solutions balance science and simplicity, giving you easy control over your water’s purity.


Activated Alumina

Worried about fluoride in your water? Our activated alumina filtration media targets and reduces fluoride effectively—helping safeguard your family’s health with every glass. Unlike basic carbon filters, this specialized technology works like a magnet to attract and trap fluoride molecules, all while maintaining clean, great-tasting water. Simple to use and long-lasting, it’s an effortless way to reduce exposure to excess fluoride and enjoy purer hydration. Because when it comes to drinking cleaner water, our drop-in filters offer peace of mind.
Fluoride Ceramic Spheres

Our advanced Fluoride complex polymer media delivers maximum fluoride adsorption, effectively reducing levels from 14 ppm to under 1 ppm (well below recommended safety thresholds). While fluoride at optimal levels (0.7-1.2 ppm) supports dental health, excess exposure poses risks, making smart filtration essential.
Unlike basic filters, our technology selectively targets fluoride while preserving beneficial minerals, giving you safer, balanced water without compromise. Whether for home or community use, our professional-grade solution ensures precise control over water quality because clean water shouldn’t come with hidden risks.
Zeolite Ceramic Spheres
zeolite
Zeolite’s high surface area and microporous structure act like nature’s molecular sponge, trapping organic pollutants, heavy metals, and odors while stabilizing pH for balanced, cleaner water. Made from all-natural minerals and fired at high temperatures, our Zeolite Ceramic Balls are a safe, versatile solution for drinking water filters, aquariums, wastewater treatment, and industrial purification. They adsorb ammonia, fluoride, and toxic metals while softening hard water delivering crystal-clear, healthier water.
 

Seriously,
better filtration media is critical to cleaner water

cuzn waslix logo
“CUZN Filter” lends its name from the discovery of KDF in the early 1980’s. KDF is a high-purity copper-zinc (CuZn) alloy that uses redox chemistry to adsorb contaminants from water.
