• Contaminants range in size. Silt and sediment range from 50 - 100 microns.

    Bacteria are roughly 5 microns and giardia cysts are even smaller.

  • In-line filters are commonly rated at 100 microns - or not at all. Our second-state filter element has an "absolute" rating at 0.2 microns. It traps contaminants other filters miss.
