|Panasonic's proprietary Auto Cleaning Filter (ACF) automatically exposes a clean filter surface when it senses that the filter is clogged. The ACF also brushes away dust that adheres to the filter, which helps prevent clogging that can impair operation or cause malfunction. This helps maintain the highly efficient electrostatic filter, the Micro Cut Filter's superior dust-collecting performance. As a result, the filter does not need to be replaced for over 10,000 hours, greatly reducing the hassle of maintenance.
A highly efficient electrostatic filter in the air intake section traps dust particles that are 1 micron or larger. By capturing approximately 7 times more dust than conventional filters, it guards the optical block and reduces the penetration of dust into the interior to provide stable operation.
