CPAP Machines
Sleep apnea machines deliver pressurized air through the nose, mouth, or both to keep your airway open while you sleep.
A clear airway helps prevent breathing pauses, shallow breathing, and snoring, improving sleep quality and daytime energy levels. Apnea machines fall into three common categories depending on the type of therapy they provide. CPAP machines deliver air at a consistent pressure set by your doctor, BiPAP machines alternate between two pressure levels as you breathe in and out, and APAP machines automatically adjust between several pressure levels as your breathing pattern or sleeping position changes throughout the night. Your doctor will typically recommend one of these three types of therapy when you receive a diagnosis. Whether you're buying your first device or upgrading, we have a great selection of sleep apnea machines for sale at CPAP Supply USA. All devices ship free and we offer 100% price protection if you find a better deal within a week or purchase.
CPAP vs. APAP vs. BiPAP — Which Machine Do You Need?
Choosing the right sleep apnea machine starts with understanding how each device delivers pressure. CPAP machines provide one fixed pressure throughout the night while APAP machines automatically adjust pressure based on your breathing patterns. BiPAP machines offer two pressure levels, one for inhaling and a lower one for exhaling, often recommended for users who need higher pressures. Your doctor will determine which therapy best supports your diagnosis, and we offer all CPAP, APAP, and BiPAP machine options to ensure you receive exactly what you need.
