Fourth stage, Purification Beads enhance the overall water quality. Last stage, Activated Carbon Fiber filters chlorine and improves the odor and taste of the water.

• Smaller Filter Pore Size - The filter pore size of the replacement filter is 0.01 microns so that it can filter out 99.99% harmful materials from the water while other brands' filter pore size is only 0.2 microns. The smaller filter pore size, the higher filtering accuracy.

Proper use and maintenance of the water filter can prolong its service life. But for optimum performance, the water filter should be replaced every 4-6 months.
