Using this Hoover lint filter is easy. First, locate the agitator insert in your top - suspended washer. Then, attach the filter bag to the bottom of the agitator insert. When you start the wash cycle, the filter will catch lint and debris, keeping your clothes cleaner. As for maintenance, after a few wash cycles, check the filter bag. If it's full of lint, simply remove it and clean it under running water. Let it dry completely before re - attaching it to the agitator. Also, make sure your washer is turned off when you're handling the filter to avoid any accidents. This filter is designed to last, but if you notice any signs of damage, it's time to replace it.
