S.Box CPAP Humidifier Water Chamber

This is a replacement chamber for the Sefam S.Box auto CPAP humidifier only. If you need a replacement heated humidifier unit, you can find this here.

The water chamber keeps your air pressure moist and warm to prevent dryness in your throat, nose and mouth. Please be aware you should only use distilled water in your humidifier, as it removes impurities. Tap water contains mineral deposits, microbes and germs, which are unsafe to breathe in. Using distilled water enhances your therapy and increases your equipment’s longevity.

Add Heated Tubing

To keep your therapy at a constant temperature and prevent rainout (condensation), consider adding the S.Box Heated Hose for optimised therapy.
