Stay clean, stay safe. This CPAP Supply Bundle includes the things you should replace periodically: the gray hose that runs from the machine to your headgear (6 ft), two replacement nasal pillows (small), and two fine machine filters. These fit a variety of CPAP machines including the popular ResMed S8 Escape - and you could spend over $60 buying these from the company. All items are new, sealed, and manufactured by known parts suppliers. Shipped free to you via USPS First Class Package.
