25 nm "cloth"

  1. Apr 7, 2017 #1
    I am looking for 25 nm "cloth" (I'm using that term loosely) my goal is to create a cheaper water filter similar to "LifeSaver bottle" (https://en.wikipedia.org/wiki/LifeSaver_bottle) which is $139

    That is not a very well defined question.
    25nm of what? A metal?
    What kind of substrate should it be attached to?
    What size do you need?
