It was the pricing that first attracted me to the site and it is the service that keeps me coming back. The phone calls adds that personal touch and the advice given comes from a sound knowledge base. I've recommended CPAP Clinic to all that I know who use CPAP

Great Prices and Services
Been a customer for a few years. I m from Alberta and prices are about a third of what they charge here - and it s covered by Blue Cross. Shipments are always super fast. Had a warranty issue once with my portable machine and CPAP Clinic replaced it no questions asked. Great service!
