CPAP Headgear Straps Slipping or Stretched: Fixes
Headgear that slips, rides up, digs in or will not hold a setting is usually stretched, dirty, or adjusted unevenly. Washing it, adjusting both sides evenly and replacing it when the elastic is worn fixes most strap problems. Strap covers can help if the straps rub.
Signs
- Straps slide up or down your head during the night
- Velcro tabs will not hold or keep popping open
- Straps dig into your cheeks, ears or the back of your head
- You need to pull straps tighter every week to get a seal
Common causes
- Stretched elastic
- Headgear fabric stretches with use and washing. Once it has lost its elasticity, it cannot hold the mask steady without extra tightening.
- Uneven adjustment
- Tightening one side more than the other twists the mask and pulls the straps out of position.
- Dirty headgear
- Oil and sweat soak into the fabric, which can irritate skin and wear the material faster.
- Worn hook and loop tabs
- Lint and wear clog the tabs so they stop gripping.
Fixes to try, easiest first
Adjust both sides evenly
Loosen all straps, put the mask on with the air running, then tighten opposite sides a little at a time so the mask sits centered.
Wash the headgear
Hand wash headgear in mild soapy water as your mask guide directs, and let it air dry. Clean headgear holds its shape better and is kinder to your skin.
Clear the tabs
Pick lint out of the hook and loop tabs with your fingers or a soft brush so they grip again.
Add strap covers
Soft strap covers reduce rubbing where straps press on your cheeks or ears. The AASM mentions them for strap marks.
Replace the headgear
Headgear is a replaceable part. Fisher and Paykel recommends checking parts for wear and replacing them on schedule.
Ask about a different headgear design with your clinician
Some masks have split back straps, top of head tubing or different strap layouts that stay in place better for restless sleepers. Your equipment provider can help.
Call your equipment provider if new headgear still will not hold the mask in place, or if straps cause skin sores. Contact your doctor if you develop skin breakdown or if mask problems are stopping you from using CPAP most nights.
Supplies that can help
Soft fabric sleeves that wrap mask headgear straps to stop red lines, rubbing and hair tangles.
Plain, mild dish soap is the cleaning agent most CPAP makers and the FDA point to for masks, tubing and humidifier chambers.

Frequently asked questions
How often should CPAP headgear be replaced?
Headgear wears out as the elastic stretches. Follow your mask maker's schedule and your insurance plan's replacement schedule, and replace it sooner if it no longer holds the mask without overtightening.
Can I wash my CPAP headgear in the washing machine?
Check your mask user guide. Many makers recommend hand washing headgear in mild soapy water and air drying it, because machine washing and dryers can wear out the elastic faster.
Why do my CPAP straps keep sliding up?
Uneven adjustment and stretched elastic are the usual reasons. Loosen everything and tighten both sides evenly with the air on. If the straps are old, replace them.
