ResMed HumidX (Standard)

Quick answer: These are genuine ResMed HumidX (standard) waterless humidifiers for the AirMini travel CPAP. HumidX is a small heat-and-moisture exchanger (HME) that captures warmth and moisture from your exhaled breath and returns it on the next inhale — giving humidification comfort without a water tank. The standard HumidX is for average conditions (the higher-moisture HumidX Plus is for drier environments). 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 standard waterless humidifier(s) — in your selected pack (3 / 6 / 50 — confirm which for this listing)

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 (standard) is the everyday version, for average conditions — it eases dryness and congestion for most users in most climates. (If you’re often in dry air, or get dryness on the standard, the higher-moisture HumidX Plus is the step up.)

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) (this) — for average conditions; the everyday choice.
• HumidX Plus — 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.
