Cleaning
CPAP hose cleaning brush
A long, flexible brush sized to reach the full length of CPAP tubing so you can scrub the inside, not just soak it.
Why it helps
Moisture collects inside CPAP tubing every night, and soaking alone does not always shift film that has built up along the inner wall. A brush that runs the whole length of the hose lets you clean it properly with mild soapy water, then rinse and hang it to dry. The FDA notes that germs from your lungs, throat or mouth can get into the mask and hose as you breathe, which is why regular cleaning matters.
How to choose
Match the brush to your tubing. Most standard CPAP tubes are about 6 feet long (ResMed lists its ClimateLineAir tubes at 6.5 ft), so the brush should be at least that long. Check the diameter: slim tubing such as ResMed's SlimLine or ClimateLineAir has a narrower inside diameter (ResMed lists 15 mm for ClimateLineAir) than standard tubing, and an oversized brush will jam. Soft nylon bristles are less likely to scratch the inner surface.
Heated tubing has a wire and an electrical connector. Keep the connector end dry and follow the tube's own cleaning instructions. ResMed says not to wash its air tubing in a dishwasher or washing machine, and not to wash components in water hotter than 131 F (55 C). If the tubing has holes, tears or cracks, replace it instead of cleaning it.
Frequently asked questions
How often should I clean my CPAP hose?
Follow your manual. ResMed's AirSense 11 guide describes washing the air tubing weekly in warm water with a mild dishwashing liquid, then rinsing and drying it out of direct sunlight.
Can I use a brush on heated tubing?
Usually yes, gently, but keep the electrical connector dry and follow the heated tube's instructions. Replace the tube rather than scrubbing harder if you see holes, tears or cracks.
