  • replacement wiring

    My new 5 month puppy decided to take out his frustration by chewing up the power cord (both ends) for my CPAP machine. I called Direct Home Medical and the lady on the phone helped me place the order. The replacement parts came in as expected and were the perfect match . Great job Home Medical!
