Hope this helps a little when it comes to understanding the size of these particles. 1 Micron = 1000 NanoMeters Note the size range of viruses in this chart… .005 – 0.3 The .005 is much smaller than many water filters claim to remove! What is important to remember is the size of viruses that have proven to be harmful or deadly to humans.
MESH and MICRON SIZES - Industrial Spec
MESH and MICRON SIZES What is a micron? Micron is the measure of length most frequently used to describe tiny particle sizes. The term micron is actually a commonly used shorthand for micrometer (American spelling) or micrometre (international spelling). The official symbol for the micron or micrometer is μm, sometimes simplified as um. A

below one micron. For materials whose particle size extends to below one micron, the Refractive Index (R I) of the material (b oth the real and imaginary parts) and the RI of the medium are all needed for accurate results when making (M ie) light scattering corrections (se e Appendix 3). Check that these RI parameters are correct. Note:

SI standardization. The term micron and the symbol μ were officially accepted for use in isolation to denote the micrometre in 1879, but officially revoked by the International System of Units (SI) in 1967. This became necessary because the older usage was incompatible with the official adoption of the unit prefix micro-, denoted μ, during the creation of the SI in 1960.
