CPAP machines use a two-stage air filtration system. This two-staged filtration system uses black and white filters.
The black CPAP filter removes pollen and large debri from the air. This filter can be washed once per week and should be replaced every six months.
The white CPAP filter removes smaller debri from the air before the air gets to the CPAP machine. These CPAP filters are disposable and should be replaced once every two weeks.
