中空纖維是如何濾菌的？ How does the hollow fiber remove bacteria?

中空纖維管壁上有無數小孔洞，以物理方式把大於膜額定孔徑（如家用濾心標示 0.2 μm）的細菌與顆粒污染物阻隔在外；不能去除溶解於水中的物質（如鹽類、溶解態金屬、溶解性化學物質），濾出的水不等於純水。第三方檢驗只涵蓋特定樣品、特定日期的大腸桿菌結果（見技術頁）。

The hollow-fiber wall has countless small pores that physically block bacteria and particulate contaminants larger than the membrane's rated pore size (e.g. 0.2 μm on the household cartridges). It does not remove dissolved substances such as salts, dissolved metals or dissolved chemicals, so the output is not "pure water". Third-party test results cover E. coli only, for specific samples and dates (see the Technology page).
