CPAP Mask Waterless Humidification | HumidX & AirMini

Waterless humidification cartridges for the ResMed AirMini travel CPAP machine — including HumidX and HumidX Plus. Unlike a conventional water chamber, these inline cartridges use heat and moisture exchange to return exhaled humidity to the next breath, with no water required. They are mask-side consumables specific to the AirMini ecosystem. If you're looking for water chamber replacements for a standard CPAP machine, those are in our humidifier parts category.

HumidX Buying Guide

Which HumidX do I need — standard or Plus?

The choice is determined by your mask type. HumidX is designed for use with nasal and nasal pillow masks; HumidX Plus is designed for full face masks and provides a higher level of humidification to account for the greater air volume involved. Both are consumables that need periodic replacement — how frequently depends on usage, but most users replace them every one to four weeks.

Importantly, both HumidX variants are only compatible with masks connected via the AirMini's integrated connector system — either through AirMini-specific mask setup packs or select ResMed masks used with a compatible AirMini setup tube kit. Standard masks connected to the AirMini via the ZephAir universal hose adapter do not support HumidX humidification, as the waterless exchange technology relies on the proprietary inline connection. If you're setting up your AirMini for travel and want to use HumidX, confirm your mask setup is AirMini-compatible before purchasing.
