DeVilbiss CPAP fine filters 4pack. These are OPTIONAL EXTRAS DeVilbiss disposable ultra fine CPAP machine filters are for the SleepCube CPAP series and the DeVilbiss Blue CPAP machine models they will last for 30 days ONLY before they need replacing.
The “OPTIONAL” extra fine particle DeVilbiss sleep machine finer particle filters are designed to filter particles as small as 0.3 microns in size they will capture finer particles than the normal regular foam filter won’t.

PLEASE NOTE: These filters are NOT washable or reusable and must be disposed of with every 30 days of use.
