Info & Guides

How Small is a Micron?

A micron is .000039 or 39/1,000,000 of an inch. Here is 3M's list of relative sizes to illustrate the minute size of a micron, and the monumental effectiveness of the 3M Aqua-Pure 3MFF101 filter, having pores 0.2 Micron in size.

  • 40 micron - Visible to the human eye (1000 times smaller than the eye of a needle)
  • 20 micron - The diameter of a human hair
  • 5-15 micron - The size of a cryptosporidium parvum cyst
  • Note: The 3MFF100 system is NOT certified to reduce bacteria. E.Coli bacteria is 0.65 micron wide by 1.7 micron long.

This system has a 1-year manufacturer's limited warranty. Please refer to the Aqua-Pure 3MFF100 Tech Data sheet or Installation Guide for details.
