Using your Samsung Magic Lint Filter is a breeze. First, turn off your washing machine and unplug it for safety. Open the access panel where the old lint filter is located. Remove the old filter and place the new Samsung Magic Lint Filter in its place. Make sure it fits snugly. Then close the access panel. When it comes to maintenance, check the filter regularly after each few washes. If you notice a lot of lint or debris, remove the filter and rinse it under warm water. Let it dry completely before putting it back in the washing machine. As for storage, keep it in a dry place away from direct sunlight. And remember, always turn off and unplug the machine before working on the filter to avoid any electrical hazards.
