CPAP Replacement Guide: Keeping Your Therapy Fresh and Effective

Maintaining your CPAP equipment is crucial for effective therapy. Here's a simplified guide to help you keep track of when to replace your CPAP supplies:

CPAP Mask Frame: Every 6 to 12 months - Note: masks with silicone frames will likely need to be replaced more often than those with harder plastic frames.

  • Signs to replace: Air leaks, discomfort, visible wear
  • Tip: Clean weekly with warm water and gentle soap

Mask Cushion: Every 3 to 6 months - Note: if your mask uses a memory foam cushion, it should be replaced monthly.

  • Signs to replace: Loose fit, discomfort, visible damage, more air leaks
  • Tip: Wipe down or clean daily with soap and water to extend life

Headgear: Every 6 to 9 months - Note: one size fits most headgear may wear out faster than headgear with multiple adjustment points.

  • Signs to replace: Stretched out, frayed fabric, needs more tightening, more air leaks
  • Tip: Fit your mask and adjust your headgear while your machine is on and avoid overtightening. Mask should be snug, not tight

Hoses & Tubing: Every 6 to 12 months

  • Signs to replace: Leaks, tears, odors, mineral build-up
  • Tip: Clean weekly with gentle soap and a tube brush, hang to drip dry

Humidifier Water Chamber: Every 6 to 12 months

  • Signs to replace: Mineral build-up, discoloration, odors, cracks, worn gaskets
  • Tip: Only use distilled water, empty and dry daily, wash with soap and water weekly

Reusable Filter: Every 6 months - Note: most modern machines use disposable filters, so refer to your product manual for more specific maintenance steps.

  • Signs to replace: Visible dirt, low airflow, machine is louder or higher pitched
  • Tip: Inspect every two weeks, rinse as needed if instructed by your machine's manual

Disposable Filter: Every 1-6 months - Note: Some modern machines use disposable filters that last up to 6 months, but older machines may call for monthly replacements. Refer to your user manual for specific guidance. 

  • Tip: Not washable or reusable, replace at regular intervals

Oxygen Cannula & Tubing: Every 3 to 6 months

  • Signs to replace: Leaks, tears, odors
  • Tip: Clean weekly with vinegar/water solution

Remember, these are general guidelines. Your specific needs may vary based on usage, care, and your equipment's manufacturer.
