CPAP full face masks cover both your nose and mouth, sealing around your cheeks, below your mouth, and either across or under your nose. While larger than other mask styles, CPAP full face masks are the best option if you breathe through your mouth at all during the night or have frequent nasal congestion. They can also be a good option as a first mask to help you adjust to CPAP therapy. Most designs today are relatively minimal for a more comfortable fit with no sight obstruction, and there are several affordable full face masks to use with your CPAP machine. Find the right fit at CPAP Supply USA and enjoy free shipping on every full face CPAP mask.
