Buy a CPAP Machine With a Humidifier: Heated vs Built-In, Prices, and What to Check
Direct answer: If you wake with a dry mouth, dry nose, congestion, or nosebleeds on CPAP, you need a machine with a heated humidifier built in, not a travel machine and not an add-on. Every machine MyRespCo sells has one: the certified refurbished AirSense 10 AutoSet is $379.99, the refurbished AirSense 11 AutoSet is $449.99 (limited stock), and the brand new AirSense 11 bundle is $849.99, all with built-in heated humidifiers, verified live on November 11, 2026. A valid prescription is required in the United States.
What a humidifier actually does
A CPAP machine pushes pressurized room air into your airway all night. Without humidification, that airflow dries out your nose and mouth, causes congestion and nosebleeds, and makes therapy hard to stick with. A humidifier adds moisture to the air before it reaches you:
| Humidifier type | How it works | Found on |
|---|---|---|
| Heated, built-in | Heated water chamber inside the machine, adjustable levels | AirSense 10 (HumidAir), AirSense 11 (HumidAir 11), every MyRespCo machine |
| Heated, with Climate Control | Heated chamber plus heated tubing, auto-adjusts to room temperature | AirSense 10/11 with ClimateLineAir tubing |
| Passover (unheated) | Air passes over room-temperature water | Older and budget machines. Weaker, no temperature control. |
| Waterless (HumidX) | Small heat-moisture exchanger in the mask, no water | AirMini travel CPAP only |
| None | No humidification at all | Some travel and budget machines |
Heated is the standard that matters. A heated humidifier with adjustable levels lets you turn moisture up in dry winter air and down in humid summer air. Climate Control, the combination of a HumidAir chamber and ClimateLineAir heated tubing, adjusts automatically and is the setup that stops rainout, the condensation that forms in a cold tube and drips into your mask.
Prices: CPAP machines with a humidifier
| Machine | Humidifier | Price found November 11, 2026 |
|---|---|---|
| Refurbished AirSense 10 AutoSet, MyRespCo | Built-in heated HumidAir, 380 mL tub | $379.99, in stock |
| Refurbished AirSense 11 AutoSet, MyRespCo | Built-in heated HumidAir 11 | $449.99, in stock, limited stock |
| Brand new AirSense 11 Complete Starter Bundle, MyRespCo | Built-in heated HumidAir 11 + ClimateLineAir-compatible heated tubing | $849.99, in stock |
| Brand new AirSense 11 AutoSet, GoCPAP | Built-in heated humidifier | $549.00 (Black Friday price) |
| AirSense 10 AutoSet with HumidAir, orderyoursupplies.com | Built-in heated HumidAir | $699.00 (SlimLine tubing) / $719.00 (ClimateLineAir tubing) |
| Resvent iBreeze Auto CPAP with heated humidifier, cpapsupplies.com | Built-in heated humidifier | $340.00 |
| ResMed AirMini AutoSet, thecpapshop.com | None. Waterless HumidX only. | $735.20 (list $919.00) |
The refurbished AirSense 10 at $379.99 is $319.01 less than orderyoursupplies' AirSense 10 with HumidAir ($699.00), the same machine with the same built-in heated humidifier. The refurbished AirSense 11 at $449.99 is $99.01 less than GoCPAP's new AirSense 11 sale price ($549.00). The Resvent iBreeze at $340.00 is the cheapest heated-humidifier machine found, but it is an off-brand machine with no myAir app and no ResMed parts ecosystem, so it is the honest budget pick only if the ResMed name and app do not matter to you. The AirMini at $735.20 costs more than any machine here and has no humidifier at all. It is a travel-only device, not a bedroom machine.
AirSense 10 vs AirSense 11, by humidifier
| AirSense 10 AutoSet | AirSense 11 AutoSet | |
|---|---|---|
| Humidifier | Built-in heated HumidAir, 380 mL tub | Built-in heated HumidAir 11 |
| Humidity levels | Off or 1-8 | Auto Climate Control plus manual levels |
| Heated tubing | ClimateLineAir (AirSense 10) | ClimateLineAir 11, different connector |
| Rainout control | Heated tube + Climate Control | Heated tube + Climate Control, auto-adjusts to room |
| Chamber replacement | Every 3-6 months, wash daily | Every 3-6 months, wash daily |
| MyRespCo price | $379.99 refurbished | $449.99 refurbished, $849.99 new bundle |
Both machines solve dryness the same way. The AirSense 11's Climate Control is more automatic, since it reads the room and adjusts itself, while the AirSense 10 needs you to pick a humidity level. If you sleep in a cold room or wake with rainout, the 11's auto adjustment is worth the $70 gap. If your bedroom is stable and warm, the 10 at $379.99 does the same job for less.
Water, cleaning, and replacement: the part buyers forget
A humidifier only helps if you maintain it. The rules are simple:
- Use distilled water, not tap water. Tap water leaves mineral deposits in the chamber and can damage the heating plate over time.
- Empty the chamber every morning and wash it daily with mild soap. Let it air-dry. A chamber left full of standing water grows biofilm.
- Replace the water chamber every 3-6 months, or sooner if it looks cloudy, cracked, or scaled. MyRespCo does not sell standalone chambers. A new chamber comes with its machines, and genuine HumidAir 11 chambers are $29.00 standard or $39.00 dishwasher-safe from DirectHomeMedical. Read our AirSense 11 accessories guide and our AirSense 10 accessories guide.
- Replace the disposable filter every 1-2 weeks and tubing every 3-6 months. A filter clogged with dust makes the humidifier work harder and the air drier.
- If you still get rainout with a heated tube, raise the tube temperature before raising the humidity level. Warm air holds more moisture without condensing.
The 6 checks before you buy a CPAP machine with a humidifier
- Confirm the humidifier is actually included: some listings sell the machine without the chamber, or with a side cover instead. MyRespCo's refurbished AirSense 10 and 11 both ship with the humidifier chamber included. Confirm before ordering anywhere else.
- Heated beats passover: a passover (unheated) humidifier adds some moisture but cannot match a heated chamber, and it cannot run Climate Control. If the listing does not say "heated," assume it is not.
- Match the heated tube to the machine: ClimateLineAir for the AirSense 10, ClimateLineAir 11 for the AirSense 11. The two tubes have different connectors and do not interchange. Do not order MyRespCo's $49.99 heated tube for an AirSense 11. Its own listing contradicts itself on this, and the genuine ClimateLineAir 11 is $46.00 elsewhere.
- Prescription: a valid prescription is required in the United States before any CPAP machine ships. Upload it at checkout, email it to rx@myrespco.com, or have MyRespCo request it from your doctor.
- Budget for the consumables: a chamber every 3-6 months ($29.00-$39.00), filters every 1-2 weeks, tubing every 3-6 months. A cheap machine with expensive proprietary consumables costs more by year two.
- Do not buy a travel machine as your bedroom machine: the AirMini at $735.20 has no humidifier, only waterless HumidX. If dryness is your problem, a travel machine makes it worse, not better. A refurbished AirSense 10 at $379.99 is the better bedroom buy and the cheaper one.
If dryness is not your problem
A humidifier adds cost and a daily chore. If you sleep in a humid climate, never wake dry, and have never had congestion on CPAP, you can run any of these machines with the humidifier off or the chamber removed. The AirSense 11 even has a side cover ($18.40) for exactly that. But do not buy a machine without a humidifier to save money: the price gap between a humidifier and a non-humidifier machine is small, and dryness is the most common reason new users quit CPAP in the first month. Read our AirSense 10 guide and our AirSense 11 guide.

Frequently asked questions
Do all CPAP machines come with a humidifier?
No. Most full-size bedside machines (AirSense 10, AirSense 11) have a heated humidifier built in. Travel machines like the AirMini have none, only a waterless HumidX insert. Some budget machines have an unheated passover humidifier or none at all. Check before you buy.
Is a heated humidifier better than a regular one?
Yes. A heated humidifier delivers more moisture, adjusts to levels you control, and with heated tubing runs Climate Control, which stops rainout. A passover humidifier adds some moisture but cannot match it.
How much is a CPAP machine with a humidifier?
The cheapest proven option verified live on November 11, 2026 is the certified refurbished AirSense 10 AutoSet at MyRespCo, $379.99, with a built-in heated HumidAir humidifier. A new AirSense 11 with a heated humidifier is $549.00 at GoCPAP.
What water should I use in my CPAP humidifier?
Distilled water. Tap water leaves mineral deposits in the chamber and can damage the heating plate.
How often should I replace the water chamber?
Every 3-6 months, or sooner if it looks cloudy, cracked, or scaled. Wash it daily and empty it every morning.
Do I need a prescription to buy a CPAP machine with a humidifier?
Yes. A valid prescription is required in the United States for any CPAP or BiPAP machine, humidifier or not.
General information only, not medical advice. Whether you need CPAP, APAP, or BiPAP, which mask type fits, and what pressure settings to use, comes from your prescriber and sleep study, not from a seller or an article.
