These are the white disposable ultra-fine filters with the tab that are used with the Respironics M-Series, System One, and SleepEasy CPAP and BiPAP machines. These filters should be replaced monthly.
Philips Respironics no longer manufactures these filters with the tab so they are available from aftermarket vendors. They are available in packs of two with quantity discounts when ordering packages of 6 or 20. The package of six will ship as 3 packs of two and the package of 20 will ship as 10 packs of two.
*** These filters fit the M-Series, SleepEasy, and SystemOne CPAP and BiPAP machines. They measure approximately 7/8 inch x 1 3/4 inches and have the tab. Philips Respironics no longer produces these filters with a tab.
