A CPAP cover assembly includes a tube that has a front end and a back end. Each of the back end and the front end is open into an interior of the tube thereby facilitating the tube to insertably receive a CPAP mask. A front elastomeric band is coupled to the tube and the front elastomeric band is aligned with the front end for biasing the front end into a substantially closed position. In this way the front elastomeric band retains the tube around the CPAP mask. A back elastomeric band is coupled to the tube and the back elastomeric band is aligned with the back end for biasing the back end into a substantially closed position. It this way the back elastomeric band retains the tube around the CPAP mask.
