More Details

Comfort That Stays With You All Night

The HumidAir Heated Humidifier built into the ResMed AirSense 11 CPAP Machine keeps your therapy smooth and comfortable by protecting you from dry mouth, congestion, and that “desert air” feeling. It quietly balances moisture while you sleep so you wake up refreshed, not dried out.

With the optional Climate Control Auto and ClimateLineAir™ 11 heated tubing, the AirSense 11 automatically manages temperature and humidity together, adjusting to your room and preventing rainout or condensation.

Why users love the HumidAir system

Personalized humidity for your comfort level
Automatic climate control for consistent therapy all night
Dishwasher-safe water tub for fast, easy cleaning
Designed specifically for the ResMed AirSense 11

Whether you’re new to CPAP or upgrading from an older machine, this built-in humidifier is a major comfort upgrade that makes therapy easier to stick with.

Travel Mode: Ninja Compact

When it’s time to travel, the ResMed AirSense 11 adapts with you. Remove the water chamber, snap on the optional AirSense 11 Side Cover, and your machine becomes lighter, smaller, and easier to pack, while keeping your personal therapy settings locked in.

Before your trip, check your sleep data with the MyAir app (available in the U.S. and Canada). Once set, your AirSense 11 remembers everything, so your therapy stays consistent wherever you land.

Life-changing sleep upgrade

I’ve been using the ResMed AirSense 11 AutoSet with HumidAir and it has honestly been a game-changer. Setup was simple, the menu is easy to use, and it’s way quieter than I expected. The AutoSet feature adjusts smoothly through the night so I’m not waking up fighting pressure, and the HumidAir has made a huge difference — no more dry throat or congestion in the morning.

What I like most is how consistent it is. It feels modern, reliable, and the comfort features actually work (ramp, humidity, etc.). I’m finally waking up feeling rested instead of drained.

Also want to shout out CPAP Ninja — shipping was fast, packaging was solid, and everything arrived exactly as described. If you’re on the fence about the AirSense 11, I’d buy it again without hesitation. Highly recommended.

Excellent customer service and a really great updated product

Excellent customer service and a really great updated product. Updated from failed four year old unit, and the unheralded improvements are a real advance. I'm back to trouble free, calm relaxing sleep. Thanks

Yay for the Ninja!

Yay for the Ninja! My insurance wouldn’t pay for my cpap. These guys were SO MUCH CHEAPER! Everything arrived perfectly and I’m set up and ready for peaceful sleep!
