Excellent service from Agnes and they actually had parts for my at least 10-year-old CPAP machine.

I am pleased to have found this company to order replacement parts for my CPAP machine. Jennifer J. was patient and efficient when I called to change my order, willing to wait while I gave long explanations that were probably not relevant to my situation. Thank you for your caring attitude.

I texted Erica at CPAP.com just this morning about replacement parts for my machine. I needed to get my prescription refilled as I needed a new nasal pillow mask. She collected my doctor’s information and placed the request within minutes, and had me call the doctor’s office to confirm. Erica was on top of the entire situation, and extremely quick with all of her responses. It was a pleasure to work with her!

The customer service is the best. Kyria was so good at finding the part for my husband's old machine. Always a pleasure working with them.
