Using this Samsung lint filter is easy. First, make sure your washing machine is turned off and unplugged. Then, locate the filter slot in your Samsung washing machine (usually at the front or side). Take the filter and gently insert it into the slot until it fits snugly. You're ready to start your wash cycle. As for maintenance, it's a good idea to clean the filter after every 2 - 3 wash cycles. Simply remove it from the machine and rinse it under running water to get rid of the lint and debris. When it comes to storage, keep it in a dry place. If you notice any damage to the filter, such as a torn mesh, it's time to replace it. And always follow the manufacturer's instructions for your specific washing machine model.
