If you are shopping for an auto CPAP machine in Canada right now, you will almost certainly end up comparing the ResMed AirSense 11 and the Philips Respironics DreamStation 2. These are the two most widely prescribed auto CPAP machines in the country, and the choice between them is a genuinely close call. Both treat sleep apnea effectively. Both have colour touchscreens, built-in humidifiers, and app connectivity. So what actually separates them?

ResMed AirSense 11: The Current Market Leader
The ResMed AirSense 11 is the most popular CPAP machine in Canada right now, and it earns that position. The colour touchscreen interface is intuitive enough that most first-time users complete setup without needing to call anyone. The enhanced myAir app gives you a nightly sleep score, AHI data, and coaching tips on your phone, which makes it genuinely easier to stay consistent with therapy in the early weeks.
The AirSense 11's AutoSet algorithm adjusts pressure breath by breath based on your airway resistance. It also features AutoRamp, which starts at a low pressure and gradually increases once you fall asleep. One consideration: the ClimateLineAir heated tubing is sold separately, whereas the DreamStation 2 includes a heated tube in the box.
Best for: First-time CPAP users, anyone who wants the most polished app experience, and patients who value a compact, modern device.
Philips DreamStation 2: A Strong Return for Philips
The Philips Respironics DreamStation 2 marks a confident return to the market after Philips' well-documented recall period. The DreamStation 2 is a completely different machine from its predecessor, with a new motor, a redesigned humidifier, and far more premium build quality.
The micro-flexible heated tube included with the DreamStation 2 is a genuine advantage, particularly for users in colder Canadian winters who would otherwise need to purchase it separately. The DreamMapper app tracks therapy data, and a Ramp Plus feature eases pressure up gradually at bedtime.
Best for: Existing Philips users, value seekers who want heated tubing included, and patients whose clinic recommends the DreamStation 2.

App Experience: myAir vs DreamMapper
myAir gives you a daily score out of 100 based on usage hours, mask fit, and event data, plus coaching messages in the early weeks of therapy. For people who want reassurance that their therapy is working, myAir is the more engaging experience.
DreamMapper provides the same core therapy data, including AHI, leak rate, and usage hours, in a clean interface. If you work with a sleep clinic that uses Philips' EncoreAnywhere platform, DreamMapper integrates directly with it.
Which Machine Should You Choose?
Choose the AirSense 11 if you are a first-time CPAP user, you want the most developed app experience, or you prefer a slightly more compact machine.
Choose the DreamStation 2 if you are already in the Philips ecosystem, your clinic works with EncoreAnywhere, or the included heated tubing makes more sense for your budget.
Either way, both machines will treat your sleep apnea effectively. The difference is mostly in the ecosystem, the interface, and a few design details.
Frequently Asked Questions
Is the ResMed AirSense 11 better than the DreamStation 2?
For most new users, yes. The AirSense 11 has a more developed app and a more intuitive setup experience. However, the DreamStation 2 includes heated tubing in the box and is a strong machine in its own right. Neither is a bad choice.
Are the masks compatible with both machines?
Yes. Both machines use a standard 22mm connection, so the same CPAP masks work with either device.
Does the DreamStation 2 have the same recall issue as the original DreamStation?
No. The DreamStation 2 is a completely new device with a different motor and foam design. It was not part of the 2021 recall and is a safe, Health Canada-authorized machine.
Can I use my existing CPAP prescription for either machine?
Yes. Your prescription specifies pressure settings, not a brand. Both machines can be configured to match your prescribed settings.
Which machine is better for travel?
Neither is a dedicated travel machine. If travel is a priority, the ResMed AirMini is the most compact option available in Canada.
