Philips Dreamstation 2 CPAP machine

Philips Dreamstation 2 CPAP machine. Only used once. Had a hard time using it because I am allergic to the mask. Includes heated tube and some new blue filters. Also include newly installed gray filter that can last for 12 months. With travel bag and user manual. You just need a new mask. Got it for $1500 and only selling for $800
