A sediment filter installed on the supply hose leading to a clothes washer intercepts particulate matter like rust, sand, and other impurities. This device typically consists of a housing containing a fine mesh screen or other filtration medium. An example is a simple inline filter screwed onto the water supply valve before connecting the washer hose.
Clean water entering the washing machine is essential for optimal appliance performance and longevity. Such filtration protects internal components from abrasive particles, preventing premature wear and tear on valves, seals, and the pump. Cleaner water can also contribute to brighter laundry by preventing sediment from redepositing on clothes. Historically, while washing machines have existed for centuries, dedicated inlet filtration has become increasingly popular with the rise of more complex and sensitive appliance technologies. The increasing prevalence of hard water in some regions has also driven demand for these protective measures.
