These original Philips Respironics brand white ultra fine fiber filters (with integrated carrier) are designed for use with all DreamStation GO Series Portable CPAP/APAP Machines. They are an optional accessory used to improve overall air filtration on the DreamStation GO. Ultra Fine filters are disposable and should be changed regularly when soiled.
Usage Information: In use this filter snaps onto the base of the DreamStation Go's foam pollen filter (sold elsewhere on this site). The plastic carrier is permanently attached to the filter. It should not be detached.
