The HumidX system uses small heat and moisture exchangers (HME) that capture heat and moisture from your exhaled breath and release it when you inhale. This process provides effective humidification without the need for a water chamber, making it ideal for travel and use in dry environments.

No, the HumidX system is specifically designed for use with the ResMed AirMini CPAP machine and compatible AirMini setup pack masks. It is not compatible with other CPAP machines.

When unopened, HumidX/HumidX Plus discs don't have a specific shelf life and can be stored without affecting their performance.

Once you open the packaging, though, ResMed recommends replacing them every 30 days. Even if you don't use your HumidX every night during those 30 days, it should still be replaced after that period to ensure you're getting optimal humidification for your therapy.

If you ever receive a HumidX with packaging that's already opened, damaged, or torn, we recommend replacing it right away with a fresh one.

Yes, but not the standard HumidX or HumidX Plus. For AirFit F20 owners, ResMed offers the HumidX F20, which is specifically designed to provide waterless humidification for the F20 full face mask. This ensures that users of the F20 can also benefit from the convenience and comfort of the HumidX system.

Though the AirFit F20 and AirFit F30 use the same AirMini mask elbow, HumidX is not compatible with AirFit F30 masks due to fundamental differences in the cushion design.
