To ensure the perfect functioning of your intake unit and reduce its maintenance, we recommend using only genuine spare parts. The filter should be replaced every 2 years max. We recommend that you clean the filter every 1/2 month. Cleaning the filter is really easy, before washing it under running water you can vacuum up the dust deposited. Read more about "how to clean a central vacuum cleaner" or watch the video "cleaning central vacuum filter." Proper filter cleaning ensures maximum suction power for long periods. The sealing gasket designed to adhere perfectly to the surface of the central body prevents unfiltered air from passing directly to the turbine, thus ensuring its proper operation. The special construction of the filter coupled with the simple and ergonomic locking system allows it to be mounted quickly and accurately. (IMPORTANT! the filter must be dry when reassembled on the central unit).
