Quick take
For most CPAP accessories, mild soap and water plus manufacturer instructions beat risky cleaning shortcuts.
The FDA says most CPAP accessories such as masks, hoses, and humidifier tanks can be cleaned with mild soap and water according to the owner's manual, and warns that many ozone or UV cleaning claims are not FDA approved or cleared for CPAP cleaning.
Practical schedule
| Part | Clean | Replace or inspect |
|---|---|---|
| Mask cushion | Often daily or per manual | Inspect for leaks, tears, skin irritation |
| Hose | Regular mild soap rinse per manual | Replace if cloudy, cracked, leaking, or smelly |
| Humidifier tank | Empty and clean per manual | Watch for mineral scale or cracks |
| Reusable filter | Rinse per manufacturer instructions | Replace if damaged or cannot be cleaned |
| Disposable filter | Do not wash unless manual says so | Replace on schedule |
What to avoid
- Do not put the CPAP machine body or anything with an electrical cord in water.
- Do not rely on unverified ozone or UV devices as a replacement for manufacturer cleaning.
- Do not use harsh chemicals unless your manual specifically allows them.
