What can mbranfiltra's hollow fiber filter out?

Bacteria, microorganisms and microplastics are contaminants commonly met in outdoor drinking water. Microfiltration hollow fiber physically retains bacteria and particles 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, and the output is not "pure water". Third-party test results cover E. coli only, for specific samples and dates (see the Technology page); there is no report for microplastics or other microorganisms.
