Ive been buying CPAP supplies from CPAP.com for almost a year now after having difficulty with our local providers. I have severe allergies and they have gone the extra mile helping me order the correct supplies and when I had to return the 1 item I had wrong it was a breeze! Family owned and operated I highly recommend going to them for all your needs! By the way Im a RN with over 30 years of experience so I am picky about who gets my thumbs up approval! Thanks CPAP.com! Love you all! If you you order and have everything they need you can expect to see it delivered the same day! Amazes me every time!
