Using your Samsung SW - T65 Series twin tub washing machine lint filter is easy. First, locate the filter compartment in your washing machine. Carefully remove the old filter and replace it with this new one, making sure it fits snugly. When it comes to maintenance, it's a good idea to clean the filter after every few loads. You can do this by gently rinsing it under running water to remove any lint or debris. If the filter gets really dirty, you can soak it in a mild detergent solution for a while and then rinse it thoroughly. As for storage, keep the filter in a dry place when not in use. Also, be careful when handling the filter to avoid any damage to the frame or the filter mesh. And remember, this filter is designed specifically for the Samsung SW - T65 Series and some compatible models, so make sure it's the right fit for your machine.
