Inline water filtration devices designed for laundry appliances remove sediment, rust, chlorine, and other impurities from the water supply. These devices typically connect to the water inlet hose and filter the water before it enters the machine. An example includes a small cylindrical unit filled with activated carbon and sediment filters.
Cleaner water benefits both the appliance and the laundry. By reducing mineral buildup, these filtration systems can extend the lifespan of a washing machine by protecting internal components from scale and corrosion. They also contribute to brighter, softer laundry by preventing the dulling and stiffening effects of hard water and chlorine. Historically, concerns about water quality led to the development of various filtration methods, with dedicated laundry appliance filters becoming increasingly common in modern households.
