The Tube Cleaning System makes it easier to keep the CPAP hose clean and healthy. The tube caps seal the ends of the hose so the cleaning solution of your choice can be applied through the hose without trying to cover the openings with your hands. Allow the solution to soak in the tube while hanging from the tube bridge and later hang the hose to dry thoroughly.Choose from one of the two options for hanging the system: Use the hook to hang from anywhere - shower curtain bar, towel rack, shower door, or shower head. Or, use the suction cup to attach the tube bridge to any smooth surface.This product includes:2 - Tube Caps1 - Tube Bridge1 - Hook Attachment1 - Suction Cup AttachmentDirections for use:Hang the tube cleaning system using the hook or suction cup.Fill the tube with a cleaning solution of your choice.
