How Often Should You Change the Hose on Your CPAP Machine?

The frequency with which you should change your CPAP hose depends on several factors, including the manufacturer’s recommendations, your specific usage patterns, and personal hygiene preferences. Generally, the guidelines for replacing CPAP hoses are as follows:

  1. Manufacturer Recommendations:

– Most manufacturers recommend replacing CPAP tubing every 3 to 6 months. This is to ensure optimal performance and hygiene, as hoses can become worn, develop small tears, or harbor bacteria over time.

  1. Type of Hose:

– Standard CPAP Tubing: This should be replaced every 3 months. Standard tubing can accumulate dirt and condensation, which increases the risk of bacterial growth.

– Heated CPAP Tubing: These should also be replaced every 3 months. Heated tubing can experience the same issues as standard tubing, but the heating element may also degrade over time, reducing effectiveness.

  1. Wear and Tear:

– If you notice any visible damage to the hose, such as holes or tears, it should be replaced immediately. Damaged hoses can lead to air leaks, which can compromise the effectiveness of your CPAP therapy.

  1. Cleaning Routine:

– Even with regular cleaning, hoses can develop a buildup of soap residue, body oils, and other contaminants. Regular cleaning can extend the life of your hose, but it doesn’t eliminate the need for periodic replacement. A good cleaning routine involves washing the hose weekly with warm water and mild soap.

  1. Insurance and DME Policies:

– If you have health insurance that covers CPAP supplies, check your policy for replacement schedules. Many insurance companies follow the same guidelines as manufacturers and allow for new tubing every 3 to 6 months.

  1. Personal Hygiene and Comfort:

– Personal preference also plays a role in how often you replace your CPAP hose. Some users may feel more comfortable replacing their hose more frequently to ensure it’s always in the best possible condition.


Maintaining and replacing your CPAP supplies, including the hose, is crucial for effective and hygienic sleep apnea therapy. Regular inspection, cleaning, and adherence to replacement schedules recommended by manufacturers, insurance policies, and personal comfort levels will ensure that your CPAP therapy remains effective and comfortable.
