| Purtrex 30 micron filters are nominally rated to filter sediment down to 30 microns. The smaller the micron rating of the Purtrex filter, the smaller the size particle the Purtrex water filter cartridge will remove. For comparison purposes, the human hair has a diameter of approximately 70 microns, and particles smaller than 40 microns are not visible to the human eye. The Purtrex 30 micron water filter will reduce small sediment particles from your water. |
