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 clogs in the dryer vent, which can lead to reduced efficiency and potential fire hazards. Regularly cleaning the lint filter is essential for maintaining optimal dryer performance. In addition to dryers, lint filters are also used in washing machines and vacuum cleaners to trap small particles. They play a crucial role in improving air quality and ensuring that appliances operate effectively. Proper maintenance of these filters can extend the lifespan of the appliances and enhance their efficiency.
