Water Chambers

CPAP water chambers, also known as humidifier tubs or tanks, are essential components of your CPAP machine’s humidification system. These chambers hold the distilled water used to add moisture to the airflow, helping to reduce dryness, irritation, and congestion often associated with CPAP therapy.

Over time, water chambers can develop mineral buildup or wear out from daily use, especially if not cleaned regularly. For optimal hygiene and performance, it’s recommended to clean the chamber daily and replace it every 6 months or as needed.

We offer replacement CPAP water chambers compatible with popular machines from ResMed, Philips Respironics, Fisher & Paykel, and other trusted brands. Choose from standard or dishwasher-safe versions for added convenience. Keeping your humidifier chamber clean and up to date is a simple way to ensure more comfortable, effective sleep therapy night after night.
