Product Overview
The VORTOPT F9 system features a dual-stage filtration process:
- Ultra Filtration (UF) Membrane: This first stage uses a 0.01µm semi-permeable membrane to physically block suspended particles, larger organic molecules, colloids, protozoa, and some viruses. It ensures harmful elements are removed while preserving natural minerals.
- Activated Carbon Filter: The second stage specializes in chemical adsorption, effectively removing chlorine (up to 99.99%), volatile organic compounds (VOCs), disinfection byproducts, lead, and other heavy metal contaminants that cause bad tastes and odors.

The system is constructed with food-grade 304 stainless steel, ensuring durability, corrosion resistance, and a leak-proof design.
