The AirFit F20 is a non-invasive accessory used for channeling airflow (with or without supplemental oxygen) to a patient from a positive airway pressure (PAP) device such as a continuous positive airway pressure (CPAP) or bilevel system. The AirFit F20 provides a comfortable fit with a secure seal, leaving a clear line of vision for watching TV or reading. The InfinitySeal silicone cushion design maintains a consistent seal even under the highest therapy pressures. QuietAir vent reduces sound to only 21 decibels, which is, quieter than a whisper. Plush headgear and soft, flexible frame provide extra comfort. Quick-release elbow allows you to get up at night and disconnect without removing the mask. The AirFit F20 is to be used by patients weighing more than 66 lb (30 kg) for whom positive airway pressure therapy has been prescribed.
