What might be a reason to replace a sediment filter?

Replacing a sediment filter is essential for maintaining water quality and system performance. Signs of clogging in the filter indicate that it has reached its capacity to trap particulates from the water. When a filter is clogged, it can restrict water flow, potentially leading to decreased water pressure and increased strain on the water system. Additionally, a clogged filter can allow contaminants to pass through, compromising water quality. Thus, timely replacement as indicated by visible signs of clogging ensures both effective filtration and optimal operation of the water system, making this the most rational choice.

While enhancing taste, increasing the flow rate, or a preset timeline for replacement might be considerations in certain contexts, they do not directly address the immediate, practical need to renew a filter based on its condition. Therefore, monitoring for signs of clogging serves as the most credible basis for filter replacement.
