A lint filter is a device commonly found in clothes dryers that captures lint and debris released from fabrics during the drying process. It helps prevent lint buildup in the dryer vent, which can reduce efficiency and pose a fire hazard. Regularly cleaning the lint filter is essential for maintaining optimal dryer performance and safety. In addition to dryers, lint filters can also be found in washing machines and vacuum cleaners. They serve a similar purpose by trapping small particles and fibers, ensuring that appliances operate effectively and prolonging their lifespan. Proper maintenance of these filters is crucial for household appliance care.
