Set of 2 filters :

(1) Ultra Filter Membrane PSU (0.1 - 0.01 micron)
It uses the industry's highest-rated PSU (polysulfone) material, which has high hardness and impact strength. It is non-toxic, heat-resistant, cold-resistant, and aging-resistant. Through the results of Taiwan's textile technology research, it has produced a better bacterial filtration technology than the past. Multi-directional filtering reduces congestion and improves user convenience. It has passed NSF/ANSI42 certification and SGS material safety report. The SGS test bacteria filtration rate reaches 99.9%.

(2) Antibacterial Activated Ag Carbon Filter
Super-effective composite Ag antibacterial activated carbon, derived from Japanese carbon-making and antibacterial technology, has super-effective adsorption power to perfectly remove chlorine, color, taste... harmful substances in water. Combined with Ag antibacterial technology, it strengthens drinking water safety requirements, eliminates bacterial breeding, and improves the highest drinking standards. The raw materials have obtained NSF certification. In addition to their safety and drinkability, they also restore the refreshing and sweet taste.
