Cleaning and Replacement Guidelines

Cleaning CPAP Supplies


As with any medical equipment, it is important for a patient to keep their sleep therapy equipment clean. We recommend that the silicone mask be hand-washed every day using warm water and a pure soap. We recommend that the headgear  be hand-washed once a week.

While your various pieces of sleep therapy equipment are durable, they are not designed to last forever and will need to be replaced at different times. Please see below for a schedule of when your items should be changed.

Examples of pure soaps include most baby shampoos and Neutrogena soap.

Suggested Replacement Time Periods for CPAP Supplies


Every 3 months

Every 6 months

  • Disposable Air Filters for the machine  
  • Full Face Cushions (1 per month) 
  • Nasal Cushions/Pillows (2 per month)

Insurance providers will usually allow for a 3 month supply of these items at once.

  • Tubing (Heated/Climate line tubing is only covered every 6 months for some insurance providers)
  • Mask frame (Includes 1 cushion)
  • Water Chamber 
  • Headgear 
  • Reusable Filter (Not all machines use this, mostly just Philips Respironics machines.) 
  • Chin Strap (Not all patients use this and it is only sent if it is a regular part of the resupply or requested by patient. This may require an updated prescription from their physician if not previously requested.)

Suggested replacement times for supplies follow eligibility guidelines created by most insurance providers, but with hundreds of providers out there, we don’t have access to all of the details about all of the plans. Because of this, we can only offer general supply times followed by most insurance providers. As a result, we can never guarantee that an item will be shipped; that determination is made by the insurance provider during the next step of the ordering process.

The patient's HME will verify if the patient is eligible to receive supplies prior to shipping by running the order past insurance, and that patient will only receive supplies that are covered.


Some patients will be reluctant to replace their supplies or they may be misinformed about the durability of their supplies. If a patient claims they do not need any supplies, see this article for some excellent ways to educate them about the nature of their supplies.  Some additional conversation tactics can also be found here
