I had a great experience with CPAP.com. The agent I spoke with named Kyria was so helpful with finding a replacement tank for my older CPAP machine when all other avenues I tried locally with DME companies had failed to do so. And she was very pleasant, thorough, and professional. I would highly recommend CPAP.com to take care of your CPAP needs based on my experience. Thank you Kyria!

CPAP.com is a great company. Hailey is a great customer service rep. She helped me find a new water chamber for my CPAP machine. Highly recommended!!

I was able to buy a water chamber for my rather old C-Pap machine so that I can continue to use it. The regular supplier wasn’t able to obtain one for me. I thought the price was good for the water chamber.
