The Disposable Ultra Fine Filters are used with all the DreamStation™ CPAP and BiPAP machines. The filter is housed in a blue frame that is permanently attached and cannot be separated. If they become separated, dispose of the filter and replace with a new one.
The disposable DreamStation Filters are an essential component in maintaining your CPAP or BiPAP machine by removing dust, pollen, and tobacco smoke particles prior to entering the CPAP or BiPAP airflow.
The filters should not be cleaned; simply replace when the filter becomes dirty or at least on a monthly basis. A dirty filter can affect the machines ability to work properly and can alter the life expectancy of your CPAP or BiPAP.
