Norwex has always known that their microfiber was at least 1/100th the size of a human hair. They knew it was smaller than that, but didn't have the studies to prove it. In the last year they have done studies on the microfiber and found it to be between 1/200th & 1/250th the size of a human hair! Half the size they originally believed! That is why Norwex microfiber works so well. It is so small that it can get into all those tiny grooves that we can't feel on our surfaces. It then lifts up EVERYTHING and hangs on to it.
Here is a picture showing how the microfiber picks up everything from the surface and then holds onto it.
