ResMed HumidX Plus

Description

Quick answer: These are genuine ResMed HumidX Plus waterless humidifiers for the AirMini travel CPAP. HumidX Plus is a small heat-and-moisture exchanger (HME) that captures warmth and moisture from your exhaled breath and returns it on the next inhale — humidification comfort without a water tank. The Plus version delivers more moisture than the standard HumidX, for drier environments (dry climates, low humidity, altitude, aircraft cabins). Each cartridge lasts up to 30 days once opened; available in 3, 6, and 50-packs. AirMini machine not included.

What’s included

• ResMed HumidX Plus waterless humidifier(s) — in your selected pack 3 / 6 / 50

AirMini machine, mask, and setup pack not included.

About this part

The AirMini doesn’t use a water tub — instead it humidifies with a small HME (heat and moisture exchanger) that sits in the mask-connector/vent path. As you breathe out, the HME’s fine paper ridges capture heat and moisture; as you breathe in, it releases them back — warming and moistening your air without any water. That’s what makes waterless, travel-friendly humidification possible.

HumidX Plus is the higher-moisture version. Where standard HumidX suits average conditions, HumidX Plus is for drier environments — dry climates, low-humidity air, higher altitude, or aircraft cabins — where you need more moisture to prevent dryness and congestion. It’s the step up if you get dryness on the standard HumidX.

It’s a disposable consumable: each cartridge is used for up to 30 days from opening, then replaced. Larger packs (the 50-pack especially) bring the per-unit cost down and keep a long supply on hand.

Compatibility: HumidX cartridges work with the AirMini and its nasal / pillow masks — AirFit P10, AirFit N30, and AirFit/AirTouch N20. They are not for the F20/F30 full face masks (the F20 uses its own HumidX F20; the F30 isn’t HumidX-compatible at all).

Specifications

HumidX or HumidX Plus?

Both are waterless HMEs for the AirMini nasal masks; the difference is moisture level:

• HumidX (standard) — for average conditions; the everyday choice.
• HumidX Plus (this) — more moisture, for drier environments (dry climates, low humidity, altitude, aircraft cabins).

Start with standard; if you still get dryness or congestion, or you’re heading somewhere dry, step up to Plus.
