The Eson 2 is a nasal CPAP mask for people who breathe through their nose and want a quiet, secure fit without a lot of bulk on the face. It uses a one-piece RollFit silicone cushion that rolls with the bridge of your nose as you move, so the seal adjusts itself instead of needing constant repositioning.The Advanced Air Diffuser built into the cushion is washable, not disposable like the filters on the original Eson, and the Easy Clip frame comes off in one piece for faster cleaning. ErgoForm headgear and VisiBlue color cues make assembly and reassembly easier to get right every time.The Eson 2 connects to any standard CPAP, APAP, or BiPAP machine with a 22 mm hose, and it is magnet-free and latex-free. This is a prescription mask, and it comes in three cushion sizes with two headgear sizes to match.
