Important Tips

  • Wipe the cushion daily with CPAP mask wipes to remove facial oils and maintain a clean seal.
  • Deep clean the cushion weekly using CPAP soap and warm water, then let it air dry away from sunlight.
  • Apply a light layer of CPAP moisturizer before bedtime if you have sensitive skin or experience redness from contact.
  • Avoid over-tightening the headgear; let the AdaptiSeal cushion naturally mold to your facial contours.
  • Replace the cushion every 1–3 months depending on signs of wear, leaks, or reduced flexibility. Use the CPAP Parts Finder to get the right replacement.
  • Always check that the cushion is fully seated in the mask frame before therapy to prevent leaks.
  • Store the cushion in a dry, dust-free area when not in use to preserve its material and shape.
  • Consider pairing with a CPAP pillow if you’re a side sleeper to reduce pressure and keep the mask stable through the night.
  • For added sanitation, use a UV CPAP cleaner weekly to eliminate bacteria without water or harsh chemicals.

FAQs

What is a CPAP cushion?

A CPAP cushion is the soft, replaceable part of a CPAP mask that sits against your face, creating a seal to prevent air leaks.

What is the difference between a CPAP cushion and a CPAP pillow?

A CPAP cushion refers to the mask's sealing component, while a CPAP pillow is a specially designed bed pillow that supports CPAP users by reducing mask pressure and improving comfort.

How often should I replace my CPAP cushion?

Every 1-3 months or sooner if it shows wear, loses its seal, or causes leaks.

How do I clean my CPAP cushion?

Wash daily with mild soap and warm water to remove facial oils and prevent leaks.

Can I use a different cushion on my CPAP mask?

No, cushions are mask-specific and should be replaced with the same brand and model.

Why is my CPAP cushion leaking?

Common causes include worn-out cushions, improper fit, excessive facial oils, or a dirty cushion. Try adjusting the fit or replacing the cushion.

Which CPAP cushion type is best for me?

Nasal cushions for nose breathers, full-face cushions for mouth breathers, and nasal pillows for minimal facial contact.
