Package of 2 genuine Panasonic HEPA Type upright exhaust filters. Each white filter pad measures 7 1/4" x 2 1/8" x 1/4". One fits in the lower part of the bag chamber lid where the air is exhausted. Since the cleaners that use these filters are not completely sealed, net filtration is rated as 99% efficient at 1 µm (micrometers - formerly microns) size particles. While this is quite good, the net filtration does not meet the stringent HEPA specification. Panasonic has replaced this filter package with their MC-V193H package containing two HEPA Type filters. These filters fit Panasonic models MC/MC-V68**, 69**, 73** and 74**. (** denotes digits 00 to 99) For similar products see our list of current Panasonic Vacuum Supplies.
