The DeVilbiss IntelliPAP™ ultra fine filters add another level of protection in filtering your CPAP or Bi-Level air at the intake portion of your machine. The ultra-fine filter is designed to catch the pollen and dirt in the air prior to air flowing to the user. The length, width, and height of the filters are designed only to be used with these specific machines.
Ultra Fine filters are disposable (do not attempt to wash) and are recommended to be replaced on a monthly basis. Depending on the user's environment, the filter may need to be replaced more frequently. Failure to properly replace the filters can cause damage to the machine over time.
