Rethink CPAP. Innovation, Starts Here.
The Best Way to Clean CPAP Hoses and Accessories Without Ozone or UV
The Best Way to Clean CPAP Hoses and Accessories Without Ozone or UV
Keeping reusable CPAP accessories properly maintained can require time and attention, particularly when dealing with long tubing, masks with multiple components, and removable humidifier chambers.
For routine cleaning, the FDA recommends following the instructions provided by the CPAP manufacturer. Many manufacturers recommend regular washing of detachable accessories using mild soap and water, followed by thorough rinsing and drying.
Why CPAP Hoses Can Be Difficult to Clean
CPAP tubing can be particularly inconvenient to wash because it is long, flexible, and difficult to inspect internally.
For tubing approved for water-based washing, users should follow the manufacturer's instructions and make sure water and the recommended cleaning solution travel through the full length of the hose.
After washing, the tubing should be thoroughly rinsed and allowed to dry completely before being reconnected.
Cleaning Without Ozone or UV
Traditional water-based cleaning physically washes and rinses compatible CPAP accessories.
The FDA recommends following the CPAP manufacturer's cleaning instructions and has raised concerns regarding unauthorized ozone and UV products marketed for CPAP cleaning, sanitizing, or disinfecting.
FDA has also stated that it had not received evidence demonstrating that ozone or UV could clean the inside surfaces of CPAP hoses or confirming that these technologies would not damage CPAP machines and equipment.
In 2024, FDA separately authorized SoClean3+ as an adjunct device to reduce bacterial populations on certain specifically identified CPAP accessories. FDA states that the device does not replace the regular cleaning procedures recommended by CPAP manufacturers.
A Water-Based Cleaning Routine
For washable components, always begin with the manufacturer's instructions.
A typical routine may involve:
- Disconnecting washable accessories from the CPAP machine.
- Washing compatible components with warm water and a manufacturer-recommended mild cleaning agent.
- Allowing water to move through the full length of washable tubing.
- Rinsing thoroughly with clean water.
- Removing excess water.
- Allowing components to dry completely before use.
Heated tubing, specialty masks, and other components may have different requirements.
Cleaning CPAP Tubing
During water-based cleaning, make sure the entire interior of washable tubing receives adequate washing and rinsing.
A quick rinse at one end may not provide consistent water movement throughout a long hose.
After washing:
- Rinse thoroughly.
- Shake out excess water.
- Position the tubing so it can drain.
- Allow air to circulate through it.
- Let it dry completely before reconnecting it.
Cleaning Masks and Other Accessories
Masks can include cushions, frames, headgear, connectors, and other components that may have different care requirements.
Separate and clean components only as directed by the manufacturer.
Avoid harsh chemicals, excessive heat, or cleaning methods that are not recommended for the particular accessory.
Cleaning Humidifier Water Chambers
Removable humidifier chambers can develop residue or mineral deposits over time, particularly when water containing dissolved minerals is used.
Follow the chamber manufacturer's recommendations for cleaning and water use. Some manufacturers permit diluted vinegar or other methods for removing mineral deposits, while others may provide different instructions.
Why Thorough Drying Matters
Moisture can remain inside hoses and other components after washing.
Allow adequate time for washable accessories to drain and dry completely before reconnecting them to the CPAP system.
Do not use excessive heat to speed drying unless specifically permitted by the manufacturer.
Final Thoughts
Routine CPAP cleaning does not need to involve ozone or UV.
For many washable CPAP accessories, manufacturer-recommended water-based washing, thorough rinsing, and complete drying provide the standard approach to routine maintenance. The important point is to follow the instructions supplied with each component rather than assuming that one cleaning method is suitable for every CPAP system.
