Are filters designed to remove dissolved matter?

Filters are typically designed to remove suspended solids, particulates, and larger particles from water rather than dissolved matter. Dissolved substances, such as salts, minerals, and organic compounds, exist in a molecular or ionic form which allows them to pass through standard filtration media. For instance, a typical sand or membrane filter can capture larger particles but cannot affect the dissolved materials.

While there are specialized treatment methods like reverse osmosis or distillation that can effectively remove dissolved substances, standard filters will not achieve this on their own. Therefore, the correct response highlights the fundamental limitation of conventional filtration methods in regards to dissolved materials. Understanding the capabilities and limitations of different water treatment processes is crucial for effective water management and meeting regulatory standards.
