3.OPTIMUM PORE SIZE: Our pore size is 0.1 micron. We all know that the smaller pore size, the higher the filtering accuracy, but the lower flow rate. Also we know that a 0.2 micron aperture is enough to filter out tiny material. Compared to the 0.1 micron filter straw on the market, our 0.1μm pore size filter straw maintains the optimum flow rate while maintaining the same filtration accuracy.
