ResMed AirFit F20 FULL FACE CPAP MASK! (SIZE LARGE) The adaptive ResMed AirFit™ F20 full face mask elements fit an astounding 97% of patients. The F20 features a high-performance spring frame and a flexible, ultrasoft InfinitySeal cushion. The F20 is perfect for those who need high-pressure sleep apnea treatment with a full face cushion for nose and mouth coverage, but don’t want to skimp on comfort or performance. The lightweight, flexible frame ensures a clear sightline for reading/watching TV, ideal for those who sometimes feel claustrophobic during therapy. The soft, dual-wall InfinitySeal silicone cushion comfortably contours the face, ensuring a secure mask fit for a variety of facial shapes and sizes. Even the sensitive nose bridge and chin areas are softly contoured, minimizing the discomfort and red marks typical with many full-face CPAP mask cushions. The cushion seal remains robust and effective all night, even at strong CPAP therapy pressures. PLEASE REVIEW ALL PICTURES CAREFULLY AND MAKE SURE YOU WANT TO PURCHASE THIS ITEM!
