Overview
HumidX gives your AirMini gentler, less drying air without a drop of water. The small blue disc sits in your mask connector, captures the warmth and dampness of every exhale, and returns them on your next breath in, so the air feels less harsh on your nose and throat.
Living with it is simple. There's nothing to fill or plug in: twist the connector open, drop in a fresh disc and twist it closed again. ResMed says to replace each one 30 days after opening, so a pack of six covers about half a year.
Key features:
- Close to a heated humidifier: In ResMed's testing in a dry bedroom, it performed much like a heated humidifier on a middle setting with an unheated tube.
- Fits four AirMini masks: It works with the AirFit N20, AirTouch N20, AirFit N30 for AirMini and AirFit P10 for AirMini.
- Needs no power: The disc has no electrical parts, so it adds nothing to your bag beyond the AirMini and its own supply.
- Spares for your mask pack: ResMed's AirMini mask packs come with one disc of each type, and these packs keep you supplied once those run out.
- Licensed in Canada: HumidX is covered by ResMed's Health Canada licence for the AirMini system, the same one that covers the machine.
- Easy to tell apart: Its blue base separates it from the grey HumidX Plus, so you can pick the right one at a glance.
HumidX suits anyone using an AirMini with an N20, N30 or P10 mask who wants moisture without the bother of water. Keep a pack at home and a couple of sealed discs in your travel kit, and a fresh, dry one is never far away.
How it works
Putting it in
Twist the mask connector open, hold the disc by its sides with the blue base facing down toward the tube, and set it in place. Press the two halves back over it, then turn them until they lock.
Daily check
Look the disc over each morning for dust, damage or dampness, and start every night with a dry one. Never wash or soak it, and take it out before you wash the mask or connector.
When to replace it
Replace it 30 days after opening the pack, even on nights you didn't use it, and sooner if it gets wet, dusty or damaged. Each disc is for one person only.

Features and use
Travelling without a water tank
With nothing to fill, your AirMini and a few discs pack into a carry-on with no water bottle and no tub to dry out. ResMed points to aircraft cabins as very dry air, which is what HumidX Plus is for, so bring one of those on overnight flights.
- Nothing to find or buy when you land
- Nothing to drain before you pack up
How the paper core works
A coil of fine paper ridges fills the disc. Breathing out warms and dampens it, and breathing in draws that warmth back toward your nose. In ResMed's testing in a cool, dry bedroom, the air came out at 70 to 80% relative humidity, close to a heated humidifier on a middle setting.
Getting the most moisture back
HumidX works with your own exhaled air, so it does its best work when your mask seals well. ResMed says leak cuts what it can return.
- Check your seal with Mask Fit in the AirMini app
- Still dry with a good seal: try HumidX Plus
- Still dry on Plus: a heated humidifier may suit you better
Which AirMini masks take HumidX
HumidX fits the AirMini only, inside the connector of the ResMed masks made for it. The AirFit F20 and AirTouch F20 take their own HumidX F20, and ResMed makes no waterless option for the AirFit F30.
- AirFit N20 and AirTouch N20
- AirFit N30 for AirMini
- AirFit P10 for AirMini
Waterless
HumidX adds moisture to AirMini therapy with no reservoir at all. There's no distilled water to buy, fill or empty, so setting up in a hotel room is as quick as setting up at home.
Moisture exchange
It recycles the moisture you already breathe out rather than adding new water. That helps the air feel kinder on your nose and throat through the night, with nothing to refill.
Vent placement
The disc sits in the mask connector, ahead of the vent where exhaled air leaves. Placed there, it catches warmth and moisture before they escape instead of after.
Starting level
ResMed designed the blue HumidX for most rooms and climates, and its guide makes it the first one to try. It's the level to settle in with before deciding whether you need more.
Common questions
How often should I replace my HumidX?
Replace it 30 days after you open the pack, whether you used it every night or only a few. ResMed explains that each breath leaves bacteria in the paper, so the clock runs from opening, not from use.
Can I clean my HumidX?
No. ResMed says washing or soaking it affects how well it works. Take it out before you wash the mask or connector, check it daily for dust or damage, and keep it clean and dry between nights.
Should I start with HumidX or HumidX Plus?
Start with HumidX. ResMed's guide treats it as the first step for most rooms and climates, and suggests moving to HumidX Plus only if your nose still feels dry or blocked once your mask seals well.
What if I see water droplets in my mask?
Take the HumidX out and try a night without it. ResMed calls humidification optional on the AirMini, and since the blue disc is the lightest option, removing it is the guide's next step.
Why does it feel like too little air?
Check the disc and the vent for a blockage first. ResMed lists a blocked or wet HumidX as one cause, and says it should be dry when you start. Replace one that's wet, dusty or damaged.
Will HumidX work with my AirSense machine?
No. HumidX is made only for the AirMini system, and ResMed says other machines and masks don't work with it. AirSense machines add moisture with a heated water tub instead.
