Ensure that your Q-Tube Muffler
is in great shape with this affordable Q-Tube Foam Replacement Kit (HD60-2550) from CPAP Man. Made by Human Design Medical — the same cutting-edge company that brought you the noise-reducing Q-Tube Muffler — this Q-Tube Replacement Kit helps ensure that your muffler stays quiet and runs just like it did when you first installed it. The kit includes everything you need to replace all the components that tend to wear out over time, including the replacement foam made from high-quality 3M Open Cell Foam, a silicone O-ring and plastic wrap. We recommend replacing your Q-Tube Muffler parts after 14 to 30 days of continual usage or when deterioration is evident.
