What’s included: Product pages list exact contents (chamber/tub only vs. lid/gasket).
Compatibility: Water chambers are device-specific—match the exact machine series/model shown on the product page.
Standard vs. cleanable: “Cleanable” versions are designed for top-rack dishwasher cleaning (per manufacturer guidance) and often last longer; both deliver the same humidity.
Care: Use distilled water. Empty and air-dry daily; clean regularly per the device manual. Avoid essential oils/conditioners that degrade plastics and seals.
Replacement: Typical lifespan 6–12 months. Replace sooner if the tub is cloudy, cracked, leaking, or smells—or if seals feel loose.
Returns & warranty: For hygiene, opened/used chambers are usually final sale; unopened items may be returnable within the window. Manufacturer warranty applies—see the product page.
Travel tips: Pack the chamber empty, remove it before moving the device, and refill at destination.

Common Questions

How do I make sure this chamber fits my device?

Match the brand + series/model on your machine to the Compatibility section of the product page. If you’re unsure, share your device model and we’ll confirm fit before you buy.

What’s the difference between a standard and a cleanable water chamber?

Function is the same. Cleanable tubs are typically dishwasher-safe (top rack) and built for easier maintenance; standard tubs are hand-wash only. Check the product page for the exact care instructions.

Can I wash my water chamber in the dishwasher?

Only if it’s the cleanable version and the manufacturer lists it as top-rack dishwasher-safe. Avoid high-heat drying cycles. Standard tubs should be hand-washed.

Can I use tap water instead of distilled water?

Distilled is recommended to prevent mineral buildup and extend tub life. If you must use tap water temporarily, empty and dry daily and clean more frequently; hard-water scale isn’t covered by warranty.

How often should I replace my CPAP water chamber?

Typically every 6–12 months. Replace sooner if you notice clouding, cracks, leaks, odour, or if the lid/gasket no longer seals. Auto-renew is optional.
