Overview
This pack is the AirFit N30 built for the ResMed AirMini, with everything between the machine and your nose in one box. The cushion cradles the underside of your nose, the AirMini tube runs to the machine, and two waterless inserts add humidity without carrying any water.
Because the AirMini doesn't come with any mask connection, each owner needs either a mask pack like this or a setup pack for a mask they already wear. Choose this one if you like a light nasal cradle that keeps your view open for reading.
Key features:
- Three sizes to try: Small, Medium and Small-Wide cushions are all included, so you can settle your size at home before you travel.
- Humidity for any room: HumidX handles everyday air, and HumidX Plus is ResMed's pick for dry rooms, high altitude and flights.
- Minimal on your face: The cradle rests below your nose instead of covering it, which ResMed designed to avoid red marks on the bridge.
- Parts sold singly: The connector, AirMini tube and HumidX cartridges each have their own ResMed part number, so you replace only the piece that wears out.
- Light to pack: ResMed UK lists the mask at 44 grams, and the waterless inserts mean there's no distilled water to carry.
This pack suits AirMini owners who prefer a nasal cradle and want one box that covers the whole trip. If you already sleep in an AirFit or AirTouch N20 at home, ResMed's N20 setup pack connects that same mask to your AirMini instead.
Note: The AirMini machine is sold separately. This mask connects to the AirMini only, and ResMed says it isn't compatible with supplemental oxygen.
How it works
Setting it up
Thread the headgear ends through the buttonholes on the frame, grey side out, and check the band isn't twisted. For humidity, drop a HumidX into the vent module coloured side down, connect the AirMini tube to the module, and push its grey end onto the machine.
Turn the cushion so its markings face you, then rest it beneath your nostrils. Draw the headgear on from the lower band until the upper band settles across the crown of your head, and finish by easing the mask off your face and back again to settle it.
Caring for it
Wash the cushion after each use and the vent module daily, using warm water and a gentle liquid detergent, and brush the vent holes. Rinse, shake out the water and leave the parts to dry away from direct sunlight.
Wash the frame, headgear and AirMini tube weekly. The HumidX is never washed: check it daily for dust or blockage, and swap it for a fresh one 30 days after opening.

Features and fit
Picking a cushion size
Medium comes fitted, with Small and Small-Wide in the box as well. Each cushion carries its size and L and R marks, and ResMed's short sizing video is further down this page.
- Line up the cushion's notch with the frame's tab, then press its edges flat
- Leaks or a sore nose can mean another size will suit you better
HumidX or HumidX Plus
The insert sits in the vent module, between the short mask tubing and the AirMini tube, coloured side down. ResMed suggests starting with HumidX and keeping HumidX Plus for very dry air, high altitude or a flight.
- Each insert lasts 30 days from opening, used or not
- Inserts can't be washed, so check them daily for dust or blockage
- Therapy still works without one if you'd rather skip humidity
Why a special N30
ResMed builds this N30 with custom ports and moves the vent off the mask into a module on the tube. That lets the HumidX sit on your side of the vent, and it's why a standard N30 can't connect to the AirMini.
- This mask runs on the AirMini only, not on a bedside CPAP
- ResMed says it isn't compatible with supplemental oxygen
Spares that wear out
Once you're set up, a few parts need replacing over time, and each one is sold separately:
- HumidX and HumidX Plus refills
- The AirMini tube, at least every six months
- For cushion spares, call us so we match the right part to this version

Under-nose cradle
The N30 cushion cradles the base of your nose instead of covering it, so little of it touches your face. Your view stays open for a book or a screen, and the bridge of your nose stays free.
Waterless humidity
A HumidX and a HumidX Plus come in the pack, one for everyday air and one for dry rooms or cabins. Neither needs water, so there's nothing to fill or spill in your bag.
Complete kit
Mask, headgear and the flexible AirMini tube are all in the box, so the pack goes straight from your bag to the bedside. Only the AirMini itself is sold separately.
Few pieces
The mask itself is a frame, a cushion and slip-on headgear. ResMed points out that so few parts make packing and cleaning simple, which counts in a hotel room.
Common questions
How often do the parts need replacing?
ResMed says to replace each HumidX 30 days after its pouch is opened, and the AirMini tube and vent module at least every six months. For the cushion, frame and headgear it sets no calendar, so replace them when they crack, tear or show discolouration.
Does this pack include the AirMini machine?
No. It holds the mask, three cushions, headgear, both HumidX inserts and the AirMini tube. The AirMini is sold separately, and it needs a mask pack like this one to connect to you.
Can I use my regular AirFit N30 with the AirMini?
No. ResMed's compatibility list marks the standard N30 as not compatible with the AirMini. The AirMini version has its own custom ports and vent position, which the standard N30 lacks. The N30 in this pack is the AirMini version, and it fits that machine only.
Will this mask work on my bedside CPAP?
No. ResMed validates the AirFit N30 for AirMini on the AirMini alone. At home, the standard AirFit N30 on your bedside machine is the version made for bedside machines, with a similar cradle-style cushion.
Can I use the pack on a flight?
The AirMini is certified for use on board and has an airplane mode, and ResMed suggests HumidX Plus for dry cabin air. The machine has no battery, so a 12 or 24 V socket needs ResMed's DC converter. Check with your airline first.
Is it quiet enough for a shared room?
ResMed measured the complete AirMini setup with this mask and tube at 15 dBA at one metre. That figure covers the machine, tube and mask together, which is the setup you'd actually be sleeping beside.
