A micron filter is designed to filter out particles of specific sizes from liquids or gases, effectively removing sediments, bacteria, and other contaminants that can be measured in microns (one-millionth of a meter). The filtration process relies on the size of the filter's pores, which allows smaller particles to pass through while trapping larger ones. This selective filtration is crucial in various applications, such as water treatment, where maintaining water quality is essential for public health.

While micron filters significantly reduce the presence of unwanted particles, they do not remove all contaminants effectively; some contaminants may be smaller than the filter’s pore size or may require different treatment methods. The effectiveness of a micron filter is also not contingent on the cleanliness of the water being filtered, as it can work with both clean and contaminated water, depending on the context. Regarding clogging, while some filters are designed to minimize this issue, it is not a definitive feature of all micron filters.
