I have always had great service and the prices are the lowest I have found. I ordered today and needed to make a correction and Erica was incredibly helpful and pleasant to work with. I will continue to order from them and I recommend them to all CPAP users.

CPAP.com has been a great provider of CPAP equipment over the last two years, orders are easily placed with fast delivery. Typically I order online but today I called in and Karla was very courteous, polite, and professional and helped me to save money by using a promotional code. Thank you Karla for the great service!

My doctor had mentioned that CPAP.COM was a smart place to shop. The website is optimum, but sometimes you need to talk with someone. This is my second order where they saved the day. Today, Miss Alma answered the phone and was extremely efficient and helpful. You call CPAP.COM and they are ON YOUR SIDE. Many Kind Regards.

I actually enjoyed my interaction with CPAP.com. Camyatta was friendly, professional, knowledgeable, and helped make my purchase easy. And let's not forget the HUNDREDS of dollars I saved by buying direct. Thank you!
