Waking up with a dry mouth, a scratchy throat, or a sore, stuffy nose is one of the most common reasons people struggle with CPAP therapy. Cool, dry air blowing all night can do that.
A CPAP machine with a humidifier adds moisture to the airflow, which can make therapy far easier to stick with. The catch is that the right machine depends on your prescription, how dry the air is where you sleep, and whether you travel.
This guide compares six popular options, explains the differences between heated and waterless humidification, and answers the questions people ask most. If you’re short on time, the quick picks below will point you in the right direction.

Which CPAP With a Humidifier Should You Buy? Too many choices can make people put off the decision. Meanwhile, uncomfortable therapy is the main reason people give up on CPAP. So a quick shortcut helps.
- If you want one dependable machine for home use: Start with the ResMed AirSense 11 AutoSet.
- If you want to spend less but keep heated humidity: Look at the AirSense 10 AutoSet.
- If you wake up with a dry nose or throat and have limited hand strength: Look at the Fisher & Paykel SleepStyle Auto.
- If you travel often: Choose a compact machine like the AirMini, and keep a home machine for nightly use.
- If you have bad nasal congestion or dryness: Choose a home machine with heated tubing, not a waterless travel device.
Most readers will land on the first or second option. If that’s you, you can skip ahead to the reviews.
Best CPAP Machine With Humidifier: Our Top Picks
Every review below follows the same order. We cover the problem it solves, who it suits, what makes it different, its strengths, its limits, whether it’s worth the price, and who should skip it.
1. ResMed AirSense 11 AutoSet: Best Overall
What problem does it solve? It gives you automatic pressure adjustment and heated humidity in one machine, so you aren’t piecing together separate parts.
Who is it best for? For most sleepers who want a home machine with up-to-date features and an easy setup, this is the one to start with. It’s also a good fit if you like checking your sleep data in an app.
What makes it different? The built-in HumidAir heated humidifier works with optional heated tubing. The touchscreen is simple to use, and the machine connects to ResMed’s app so you can follow your nightly results.
It also offers automatic climate control with the right tubing. In practice, that means the machine adjusts humidity and tube temperature to match your room, rather than leaving you to guess at a number. If you prefer to be in charge, you can set humidity manually from Off through Level 8.
What We Like
- Integrated heated humidifier
- Optional heated tubing to reduce condensation
- Automatic climate control, or manual settings
- Touchscreen and app connectivity
What to Consider
- Costs more than the AirSense 10
- Heated tubing is an extra cost in some packages
- Water chamber needs regular cleaning, like any heated humidifier
Is it worth the price? If dryness has been your biggest complaint, the combination of a heated chamber and heated tubing is one of the strongest ways to fix it. A machine you actually use every night is worth more than a cheaper one that sits in the closet.
Who should skip it? If you mostly want the lowest price, or you only need a machine for occasional trips, look at the options below.

2. ResMed AirSense 10 AutoSet: Best Value
What problem does it solve? It delivers a proven heated humidifier and automatic pressure at a lower price than the newest model.
Who is it best for? Budget-conscious shoppers who want the same core comfort features without paying for the latest design.
What makes it different? The AirSense 10 has been a go-to home machine for years. It uses an integrated heated humidifier and works with ClimateLineAir heated tubing. It has a slightly larger footprint than the 11, but many people find the water tub easy to handle.
What We Like
- Integrated heated humidifier
- Compatible with heated tubing
- Long track record and wide availability of supplies
What to Consider
- Older design than the AirSense 11
- Stock, warranty coverage, and pricing vary by seller
Is it worth the price? For many sleepers, yes. In practice, the day-to-day comfort difference compared with the AirSense 11 is smaller than the price gap suggests. One thing to keep in mind: check the warranty, since it can differ depending on where you buy.
Who should skip it? If you want the newest app and touchscreen experience, the AirSense 11 is the better match.
3. Fisher & Paykel SleepStyle Auto: Best for Humidity-Focused Comfort
What problem does it solve? It makes humidified therapy easy to set up and easy to maintain, which matters if you struggle with small clips and latches.
Who is it best for? People who get dry airways and want a machine built around humidity comfort. It also suits anyone, including users with arthritis, who finds water chambers fiddly.
What makes it different? It pairs a built-in heated humidifier with a ThermoSmart heated tube, and the water chamber is designed to be easy to open and fill. Compared with ResMed’s approach, the focus is on simple handling and consistent moisture.
What We Like
- Built-in heated humidifier with heated tube
- Easy-to-use water chamber
- Comfort-focused design
What to Consider
- Bulkier than some competitors
- Some accessories and availability vary by region
Is it worth the price? If humidity comfort is your top priority, it’s worth considering. Compared with the AirSense line, you may give up some app features but gain simple handling.
Who should skip it? If you want the smallest possible bedside footprint or the largest ecosystem of accessories, ResMed has the edge.
4. React Health Luna G3 Auto: Best Alternative Home CPAP
What problem does it solve? It gives you another heated-humidity option if the ResMed and Fisher & Paykel machines don’t fit your budget or provider.
Who is it best for? Shoppers who want to compare more than the big two, or whose equipment provider carries this brand.
What makes it different? The Luna G3 offers a heated humidifier and heated tubing options, depending on the exact model and bundle. Because packages vary, confirm what’s included before you order.
What We Like
- Heated humidification available
- Heated tubing options
- Another choice if other brands are hard to find
What to Consider
- Menus can feel less intuitive than the AirSense
- Humidifier and tubing may be sold separately, depending on the package
Is it worth the price? It’s worth a look if the pricing is meaningfully lower than the AirSense models. If the savings are small, the AirSense is easier to recommend.
Who should skip it? If you want the simplest controls and the biggest support network, start with ResMed.
5. ResMed AirMini: Best Compact Travel CPAP With Humidification
What problem does it solve? It lets you keep up your therapy on trips without packing a full-size machine.
Who is it best for? Frequent travelers who want something small and light, and who are fine with waterless humidity.
What makes it different? The AirMini uses HumidX, a waterless system. Instead of heating water, it captures moisture from your own breath and returns some of it to the air you inhale. That means no water chamber, no refills, and a much smaller device.
One limitation to keep in mind: this is not the same as a heated water chamber. It adds some moisture, but not as much as a heated humidifier. It also needs compatible masks, and the accessories add to the total cost.
What We Like
- Very small and light
- No water to carry or fill
- Easy to pack in a carry-on
What to Consider
- Less moisture than a heated humidifier
- Works with specific masks or adapters
- Accessories add cost
Is it worth the price? If you travel several times a year, it can make sense as a second machine. As your only machine, it may not be enough if you get very dry.
Who should skip it? If you need strong humidity every night, choose a home machine.
Check the AirMini and compatible accessories
6. Transcend Micro Auto: Best Lightweight Travel Alternative
What problem does it solve? It’s another very light travel option for people who don’t want to be tied to ResMed masks.
Who is it best for? Travelers and campers who care most about weight and packing space.
What makes it different? The Transcend Micro Auto is a compact auto-adjusting travel machine that works with a compatible waterless humidification accessory. Compared with the AirMini, you’ll want to look closely at mask compatibility and sound levels.
What We Like
- Extremely light and compact
- Waterless option for travel
- Auto-adjusting pressure
What to Consider
- Waterless humidity is limited
- Can be louder than home machines
- Accessories sold separately
Is it worth the price? If you value the lightest setup, yes. If you need heat and moisture every night, it is not a substitute for a home machine.
Who should skip it? People who need a traditional heated humidifier should skip a travel device and pick one of the home machines above.

What Is the Best CPAP Machine With a Heated Humidifier?
A heated humidifier warms water in a chamber and adds that moisture to the air your machine delivers. Warm, moist air is gentler on your nose and throat than cool, dry air.
For most sleepers with dry mouth, nasal dryness, or congestion, a heated humidifier is the most effective way to add moisture. Of the machines above, the AirSense 11, AirSense 10, SleepStyle Auto, and Luna G3 are the home options built around this feature.
Heated tubing is the other half of the equation. It keeps the air warm on its way to your mask, which reduces water droplets forming inside the hose. Without it, the humidity you worked to add can condense before it reaches you.
Integrated vs. Separate Humidifiers
Many home machines have a humidifier built into the same unit. Others offer a humidifier as an add-on.
Integrated units are simpler to set up and take up less space. Add-ons give you flexibility, but they can cost more and require extra compatibility checks.
Is a Heated Humidifier Better Than Waterless Humidification?
In most cases, a heated humidifier delivers more moisture. A waterless system is smaller and easier to travel with.
| Heated humidifier | Waterless (HME) | |
|---|---|---|
| Moisture level | Higher, adjustable | Lower, depends on your breath |
| Size | Larger | Very compact |
| Maintenance | Cleaning and water refills | Replace or clean the exchanger |
| Power use | Higher | Minimal |
| Best for | Nightly home use | Travel and short trips |
Results vary depending on your mask type, climate, and how dry your airway gets.
Travel CPAP Machine With Humidifier: Which Should You Choose?
A travel CPAP is built to be small and light. A standard bedside machine is built for comfort and features.
That difference matters for humidity. Travel machines mostly use waterless exchangers, while bedside machines use a heated water chamber.
Here’s the key point, and it clears up a lot of confusion: as far as we can tell, there is no ultra-portable travel CPAP with a traditional heated water chamber. If a listing suggests otherwise, check the manufacturer’s documentation before you buy.
What Is the Smallest CPAP With a Humidifier?
The smallest options are the ResMed AirMini and the Transcend Micro Auto. Both use waterless humidification, not a heated chamber.
When you compare size, look at your whole setup. Include the hose, power supply, mask, and humidity accessory, not just the device itself. The final weight can be higher than the headline number.
Best Travel CPAP Machine With Humidifier
For most travelers, the AirMini is a strong starting point because of its size and its dedicated waterless humidification system. The Transcend Micro Auto is worth considering if low weight is your top priority.
If you want more detail on battery use and off-grid power, read our guide to the best battery-powered CPAP machine.
A quick power note: heated humidifiers and heated tubing use far more power than a CPAP running alone. That’s a big reason travel machines go waterless, and it matters if you plan to camp or use a battery.
Should a Travel CPAP Replace Your Home Machine?
For most people, no. A travel machine works best as a second device. Your home machine handles the nightly work, and the travel device covers trips.
What if you’re on a plane or in a hotel for just a few nights? A waterless setup is usually enough. For long stays, you may miss the comfort of heated humidity.
Best Auto CPAP Machine With Humidifier
An auto CPAP, also called APAP, adjusts pressure through the night based on your breathing. A fixed-pressure CPAP stays at one pressure.
Here’s something many shoppers miss. Automatic pressure and humidification are separate features. An auto CPAP does not automatically include a humidifier, and a humidified machine isn’t always an auto model.
| AirSense 11 AutoSet | AirSense 10 AutoSet | SleepStyle Auto | |
|---|---|---|---|
| Auto-adjusting pressure | Yes | Yes | Yes |
| Humidifier type | Integrated heated | Integrated heated | Built-in heated |
| Heated tubing | Optional | Compatible | ThermoSmart tube |
| Comfort features | Touchscreen, app, climate control | Proven comfort settings | Easy-fill chamber |
| Ideal user | Most home users | Value shoppers | People who prioritize humidity and ease of use |
When you compare these machines, look at pressure relief, ramp features, noise, and how easy the machine is to clean. Your clinician’s prescription should guide the final choice.
Is CPAP Better With a Humidifier?
For many sleepers, yes. Humidity can ease dry mouth, nasal dryness, irritation, and congestion, which makes it easier to wear your mask every night.
That said, some users are comfortable without it. If you live in a humid climate or have no dryness symptoms, you may not need much, or any.
A humidifier improves comfort. It does not change how CPAP treats sleep apnea. The therapy works the same either way.
There are trade-offs. Humidifiers add cleaning, refilling, and the chance of condensation. Waterless systems cut that work, but add less moisture.
The bottom line: if dryness is making therapy uncomfortable, a humidifier is worth serious consideration. If it isn’t, you may not need the extra maintenance.
Do All CPAP Machines Have Humidifiers?
No. Some home machines have integrated heated humidifiers. Others offer humidifiers as optional add-ons, and many travel machines use waterless systems or none at all.
It helps to know three terms:
- Included humidifier: Comes with the machine.
- Compatible accessory: Works with the machine but is sold separately.
- Optional add-on: An upgrade you choose to buy.
Does My CPAP Machine Have a Humidifier?
Here’s how to check:
- Look up your exact model on the manufacturer’s website.
- Look for a water chamber or tub attached to the machine.
- Open the settings menu and look for humidity or climate control.
- Check the user manual to confirm your configuration.
A tip: the same machine family can come in different packages. Confirm your model and what’s included, not just the product name.
If you’re also comparing comfort features, our guide to the most comfortable CPAP machine covers pressure comfort and more.
Best CPAP Humidifier Setting for Comfortable Sleep
There isn’t one best setting for everyone. The right level depends on room temperature, outside humidity, your comfort, and whether you use heated tubing.
For example, the AirSense 11 allows manual humidity settings from Off through Level 8. Start with the manufacturer’s recommended setting, then adjust based on how you feel.
Automatic vs. Manual Climate Control
Automatic climate control adjusts moisture and tube temperature to your room. Manual control lets you pick a level yourself.
If you’re new to CPAP, automatic is often the easier place to start. If you like to fine-tune, manual gives you more control.
What Should I Do If My CPAP Air Feels Too Dry?
- Make sure there is water in the chamber and the machine is set up correctly.
- Raise the humidity setting one step at a time.
- Consider heated tubing if your machine supports it.
- Talk to your sleep clinician or equipment provider if dryness continues.
Persistent dry mouth can also come from mouth leak, not only low humidity. A different mask or chin strap may help.
How Do I Stop Water From Collecting in My CPAP Hose?
Water in the hose is called rainout. It happens when warm, moist air cools down inside the tube.
The main fixes are:
- Heated tubing, which keeps the air warm along the whole hose.
- A hose cover or sleeve, which adds insulation if you don’t have a heated tube.
- A lower humidity setting, especially in a cool bedroom.
- Warming the room slightly, or moving the machine below the level of your bed with the hose looped upward.
Follow your machine manufacturer’s guidance for any change.
How Do I Change the Humidifier on My CPAP Machine?
There are two different things people mean by this, and they have different answers.
Changing the humidity level: Use your machine’s comfort or climate settings. On most machines, this takes a few taps.
Replacing the humidifier part: This means removing, cleaning, and refilling the water chamber, or swapping a worn one. Follow your user manual for the exact steps.
For safety, don’t fill or remove the water chamber while the machine is running. Don’t submerge electrical components unless the manufacturer says it’s allowed.
If the chamber is cracked or the machine has a fault, contact your equipment provider.
How Often Should I Clean My CPAP Humidifier?
Follow the schedule in your manufacturer’s instructions. In general, empty and dry the chamber each day, and do a deeper clean on a regular schedule.
When you clean, check for cracks, cloudy spots, discoloration, and mineral deposits. These can mean it’s time for a replacement.
Water requirements vary by model, so check your manual. Many manufacturers recommend distilled water because it reduces mineral buildup, but check your specific device.
How to Choose the Best CPAP Machine With a Humidifier
Here’s a simple way to decide.
Heated vs. Waterless Humidification
Heated humidifiers give more moisture but are larger and need more upkeep. Waterless systems are tiny and easy to travel with, but they add less moisture.
If your priority is nightly comfort, choose heated. If your priority is packing light, choose waterless.
Built-In vs. Optional Humidifier
Built-in humidifiers are simpler to set up. Optional ones can add cost and compatibility checks. Check replacement-part costs for either.
CPAP vs. Auto CPAP
A fixed-pressure machine keeps one pressure. An auto machine adjusts through the night. Neither is better for everyone. Your clinician’s prescription decides which you need.
Humidifier Capacity and Heated Tubing
A larger water chamber means fewer refills. Heated tubing means less condensation. For many sleepers, tubing makes the biggest difference to everyday comfort.
Noise, Size, and Ease of Cleaning
Quiet machines are easier to sleep next to. Small machines are easier to pack. Simple chambers are easier to keep clean, and you’re more likely to stick with what’s easy.
Price, Warranty, and Prescription Requirements
Look at the full cost: machine, humidifier, tubing, mask, and supplies. Prescription rules and insurance coverage vary by location and provider.

Frequently Asked Questions
Is a CPAP machine with a humidifier worth it?
For many sleepers, yes. If you get a dry mouth, dry nose, or irritated throat, humidity can make therapy more comfortable and easier to keep up. If you have no dryness symptoms, you may not need one.
Can I use my CPAP machine without the humidifier?
Often you can, but it depends on the model. Some machines let you turn humidity off or remove the chamber. Check your manufacturer’s instructions first. Some models can use a side cover when the chamber is removed.
Does a CPAP humidifier help with dry mouth?
It can. But persistent dry mouth is sometimes caused by mouth leak, not low humidity. If a humidifier doesn’t help, ask your clinician about your mask fit.
Should I use distilled water in my CPAP humidifier?
Many manufacturers recommend it, because it reduces mineral buildup and scale. Requirements vary by device and chamber, so check your manual for the correct water type.
Can I use a CPAP machine with a humidifier while traveling?
Yes. You can pack your home machine, or bring a compact travel model. A home machine keeps your heated humidity, but takes more space. A travel machine is smaller but uses waterless humidity, which adds less moisture.
What is the smallest CPAP machine with a humidifier?
The smallest machines are the ResMed AirMini and Transcend Micro Auto. They use waterless humidification, not a heated water chamber. Machines with heated chambers are larger.
What is the difference between a CPAP humidifier and heated tubing?
The humidifier adds moisture to the air. Heated tubing keeps that air warm so moisture doesn’t condense in the hose. They work best together.
Can a CPAP humidifier cause too much moisture?
Yes. Too much humidity can lead to water droplets in the tube or mask. Lowering the setting, adding heated tubing, or adjusting room temperature usually helps.
Does an auto CPAP machine come with a humidifier?
Not automatically. Auto pressure adjustment and humidification are separate features. Check the product page to see if a humidifier is included.
Our Bottom Line
If you want one machine that handles most needs, the ResMed AirSense 11 AutoSet is the easiest place to start. It combines heated humidity, heated tubing, and auto pressure in one machine.
If price matters more, the AirSense 10 AutoSet gives you much of the same comfort. If you value easy handling, the Fisher & Paykel SleepStyle Auto is worth considering. For travel, add an AirMini or Transcend Micro Auto as a second machine.
Prices and availability change, so it’s worth checking the latest price on the model that matches your needs before you decide. A comfortable machine is the one you’ll actually use every night.
