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

Water Filter Gravel is composed of sub-angular, hard, durable, and dense grains of predominately siliceous material. Extracted from a clean glacial deposit, Its physical properties make it among the finest available in the world for water filtration appli

To avoid problems in backwashing, the recommended effective size of the underlying sand medium is 0.75 to 0.90 mm for anthracite densities of 1.45 to 1.65. The use of a single-medium coarse-sand filter is practiced in Europe. For example, sand with a size
