filtration efficiency

Filtration efficiency refers to how well a filter can remove particles from air or liquid. It is usually expressed as a percentage, indicating the proportion of particles that the filter successfully captures compared to the total number that passes through it. For example, if a filter has a 95% efficiency, it means it removes 95% of the particles, allowing only 5% to pass. This measure is important for understanding how effectively filters improve air and water quality, impacting health and safety in various settings, such as homes, workplaces, and healthcare facilities.
