"Every water filter system makes tap water taste better", CUZN Filter uses premium filtration media to remove more contaminants for better-tasting water you'll actually enjoy drinking, while making your water filter last noticeably longer than what you have been used to.

Nobody wants arsenic in their water—it’s dangerous even in tiny amounts. Luckily, modern filtration makes it easy to eliminate. Arsenic resin uses iron-infused technology to trap arsenic (along with other contaminants like chromium and nitrate), quickly bringing levels below 10 ppb—no PH adjustments needed. For even tougher cases, arsenic ceramic spheres work like microscopic sponges, slashing arsenic from 470 ppb down to nearly zero (less than 1 ppb). They’re simple to maintain and fit into home filters or large treatment plants.
Want extra protection? Activated alumina (those high-purity ceramic balls) also grabs arsenic while removing fluoride, lead, and bacteria. It’s tough, long-lasting, and certified safe for drinking water.
The bottom line? The filtration media used in this drop-in filter cartridge makes arsenic removal effective, affordable, and hassle-free—whether you’re a homeowner or running a city’s water system. Clean water shouldn’t be complicated, and now it doesn’t have to be.
This high-quality macroporous anion exchange resin combines hydrous iron oxide nanoparticles within a polystyrene matrix to effectively adsorb arsenic (both arsenate and arsenite), hexavalent chromium, nitrate, perchlorate, sulfate, selenium, fluoride, and other oxyanions.
A powerful water filter media that adsorbs large arsenic contaminates from water for an easy and reliable way to control arsenic concentrations from water; it works so well that it can reduce levels from 470 parts per billion (ppb) down to less than 1 part per billion - practically undetectable.
Activated alumina is a highly effective water filtration media that removes dangerous contaminants like fluoride, lead, mercury, arsenic, and selenium from your water. Made from porous, high-purity ceramic balls containing over 92% aluminum oxide, it works like a powerful magnet to trap these harmful substances while also naturally preventing bacterial growth.
