What is the primary purpose of microns in water filtration?

The primary purpose of microns in water filtration is to indicate filter pore size. Microns serve as a measurement unit that specifies the size of the openings in a filter. For example, a filter rated at 5 microns can effectively trap particles larger than 5 microns, which may include sediment, bacteria, and other contaminants, while allowing cleaner water to pass through. This measurement is crucial in selecting the appropriate filter for specific applications, ensuring that the filter can remove undesired substances from the water without compromising flow rates.

In contrast, measuring pH levels, assessing water temperature, and determining conductivity are all separate properties of water quality that do not pertain to the filtration process or the role of microns. Each of these aspects is important for evaluating water quality, but they do not relate to the physical structure or function of filters, which is where microns are specifically relevant.
