Strong Adsorption * Wide Contaminant Removal * Stable Performance * OEM Ready

The Viano UDF Granular Activated Carbon (GAC) Filter Cartridge is designed for effective pre-filtration in water purification systems. Using high-quality granular activated carbon, it efficiently adsorbs residual chlorine, bacteria, organic compounds, and heavy metals, improving water safety and taste. With stable performance and long service life, this cartridge is widely used in RO systems, UF systems, and household water purifiers for OEM and bulk supply.

Essential Pre-Filter for Water Purifiers
UDF cartridges are commonly used as the first or second filtration stage in RO and UF systems to reduce chlorine and large contaminants.

Wide Contaminant Adsorption
Granular activated carbon effectively removes chlorine, organic matter, heavy metals, and odor-causing substances.

Improves Taste & Protects Downstream Filters
Enhances water quality while extending the service life of CTO and RO membranes.
