Using this Bosch lint filter is easy. Just remove the old lint filter from your dryer and insert this new one in its place. Make sure it fits snugly. When using your dryer, the filter will catch lint and debris, helping your dryer work more efficiently and safely. As for maintenance, it's a good idea to clean the lint filter after every use. Simply take it out, gently shake off the loose lint, and then use a soft brush to remove any remaining bits. If the filter gets really dirty, you can wash it with mild soap and water, and let it dry completely before putting it back in the dryer. Remember, if you're not sure if this filter is right for your Bosch dryer model, contact us with your full model number before making a purchase.
