The LV-7585 comes with a cartridge-type air filter that can be replaced with a one-touch operation. The system can be used for up to 10,000 hours before replacement.
The filter consists of a rolled-up filtering strip within the cartridge that has an area equivalent to 10 ordinary flat filters. The filter winds the strip forward automatically when it detects that the filter is clogged. The filter strip can also be advanced manually using the remote control.
