As the primary point of contact during CPAP therapy, a CPAP mask cushion wears out over time from constant use. Patients can prolong the life of their mask cushion by cleaning CPAP masks regularly and using CPAP mask wipes to remove dirt, oils and other residues that can compromise an effective mask seal. Masks cushions and nasal pillows can also develop leaks from small tears or deformation, requiring close physical inspection or running the mask seal diagnostic offered by some CPAP machines. CPAP mask user guides and instructions may offer specific mask cushion replacement guidelines, but it's a good idea to have replacement CPAP mask cushions and nasal pillows in reserve as a back-up. Don't lose sleep because your CPAP therapy is fighting against a mask leak or poor seal. The replacement CPAP mask cushions and nasal pillows from Sleep Direct will help keep your sleep therapy running at maximum efficiency.
