The Philips Respironics Disposable Ultra Fine Filter for DreamStation CPAP & BiPAP Machines – 2 Packs. These are the original Philips Respironics branded disposable ultra fine filters made of polyester fibers in a light blue carrier compatible with all DreamStation CPAP & DreamStation BiPAP Machines. Comes with two filters. The Disposable 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.
Note: If they become separated, dispose of the filter and replace with a new one.
