The Disposable filter for AirMini™ Travel CPAP Machine is available in a 1, 2, or 6 pack.
These filters are not intended to be washed, but rather disposed of and replaced every 6 months. Check for particle blockage often. Replacement may be necessary sooner if the filter becomes noticeably discolored.
The filter is located below the perforated filter cover on the side of the CPAP travel device.
