What are point of use filters used for?

Point of use filters are specifically designed for immediate water purification directly at the tap or the specific point where water is used, such as kitchen sink faucets or water dispensers. This type of filtration system is advantageous because it allows homeowners and users to access clean, safe drinking water without the need for extensive treatment facilities.

These filters remove contaminants such as bacteria, viruses, sediment, chlorine, and other impurities, effectively improving the water quality for direct consumption. By focusing filtration at the point of use, these systems can also provide better convenience and faster access to clean water compared to larger treatment processes that may treat water before it reaches the tap.

The other choices do not accurately describe the function of point of use filters, as they generally pertain to larger systems or different applications in water treatment and enhancement.
