UDF activated carbon double effect filter element

Dual-Action Filter Cartridge Features
Simultaneous Filtration: Effectively removes both impurities and residual chlorine for cleaner, safer water.
Adhesive-Free Construction: All joints are manufactured using a fully thermal-welded process—no glue used, ensuring safety and environmental friendliness.
High-Efficiency Grooved Design: Equipped with a grooved PP filter cartridge; deep grooves increase filtration surface area by 70% for enhanced performance and extended lifespan.· Constructed with high-quality needle-punched cotton instead of low-cost foam to effectively prevent bacterial growth, microbial contamination, and adhesive leaching—ensuring clean and safe drinking water.
· Equipped with a top cushion made from durable TPR (Thermoplastic Rubber) for added protection and longevity.
· Uses 100% virgin coconut shell activated carbon and brand-new polypropylene materials for superior filtration performance and material safety.
· Manufactured with a fully thermal-welded process—completely adhesive-free to eliminate potential water contamination.
· Features our patented BL@CKFREE 2-in-1 design that ensures zero carbon leakage and provides complete protection for the RO membrane.
· Made entirely from virgin materials; no recycled content is used, safeguarding water hygiene and consumer health.
