The purpose of the water filter is not to kill the creatures, but to capture them inside the filter and prevent you from ingesting them. The effectiveness of the water filter is determined by what is known as the pore-size efficiency. This is the measurement of the size of the openings in the water filter. These measurements are microscopic.

The measurement used to describe the size of the filter’s openings is called a micron. One micron is 1/1,000 of a millimeter. Any water filter with a micron size of one or less will remove parasitic eggs and larvae from the water as well as protozoa. To remove bacteria, the micron size must be less than 0.4 microns.
