Made with only high quality, durable materials, our CPAP filters will prevent dust, pollen, dirt, and more from disrupting your breathing and entering your lungs. Large and even smaller, fine particles are blocked to help you breathe clean and breathe easy. The filters also help to keep the debris out of your CPAP motor, keeping your machines working for longer. Each filter is individually wrapped to keep them in perfect condition until they are ready for use. They are easy to carry and pack, making it simply easy to take along with you during travel or for storage. Each package comes with fifteen (15) individually wrapped CPAP filters compatible with AirSense S9 & 10 Series, AirCurve Series, and AirStartSeries.
