Using this Bosch dust container filter is easy. First, turn off your cordless vacuum and unplug it. Open the dust container unit and remove the old filter. Then, place this new filter in its spot. Make sure it fits snugly. When using the vacuum, don't overfill the dust container as it can put extra strain on the filter. As for maintenance, check the filter regularly. If it looks dirty, gently tap it to remove large debris. You can also wash it with water, but let it dry completely before putting it back in the vacuum. Keep it away from direct heat when drying. This will help your filter last longer and keep your vacuum working great.
