White Ultra Fine Filters for PR SystemOne, REMstar M-Series & SleepEasy

These disposable ultra fine filters are designed for use with all PR SystemOne, M-Series and SleepEasy CPAP/BiPAP Machines. They were originally manufactured with a small tab on the long edge; however Respironics no longer includes the tab as it has been determined that it can cause the filter to pop out of the machine during use.
