Reduce Air Noise in CPAP Tube

The Qtube™ In-Line CPAP Muffler by HDM attaches between any CPAP device and CPAP tubing to help reduce machine and airflow noise. The noise will be reduced, allowing the user to fall asleep more easily. To find more information about the Qtube™ In-Line CPAP Muffler, click here.

The Qtube™ In-Line CPAP Muffler can easily be disassembled and reassembled to replace the internal components.  

Qtube™ Disassembly Tips

Remove the Retaining Clip of the Qtube by placing your finger tip in the slot and pulling away from the body of the Qtube. 

Holding the top of the End Cap, turn slightly clockwise to align the pins with the vertical slots on the Qtube body. Firmly pull upward on the End Cap to remove the piece from the device.

The red colored O-Ring seals tightly around the End Cap and should provide significant resistance when pulled. Should the O-Ring become loose from the End Cap, take care to make sure the O-Ring is not lost.

Use a finger tip to pull the foam layer up and out from inside the Qtube.

Release the clasps on the exterior of the plastic sleeve to remove and replace the foam layer.

Re-assembly Tips

Stretch the plastic sleeve open and lay the replacement piece of foam in the middle of the plastic sleeve. Roll the plastic sleeve around the foam so that the edges meet and the tabs are adjacent to each other.  Interlock the tabs on the plastic sleeve.

Push the plastic sleeve with new foam insert into the body of the Qtube all the way until the bottom of the material contacts the opposite end of the Qtube.  Look into the Qtube to check that the center is clear and there are no obstructions to the airflow. 

Make sure that the O-Ring is seated in the groove at the bottom of the End Cap, align the pins on the End Cap, push downwards, and twist slightly counter clockwise until the pins return to the locked position. 

Replace the Retaining Clip by pressing straight down until it “clicks” into place.
