A look at the features and performance of the Philips Dreamstation 2 Advanced, one of the most advanced auto-adjusting CPAP machines available.
Choosing the right CPAP machine can feel overwhelming, especially when you’re balancing features, comfort, and long-term reliability.
For people with obstructive sleep apnea, the machine you select becomes part of your nightly routine for years to come. It needs to work quietly in the background, suit your needs now and in the future, and make therapy as comfortable as possible so you’re motivated to actually stick with it.
The Philips Respironics DreamStation 2 Auto CPAP Advanced with Humidifier represents the latest evolution in auto-adjusting continuous positive airway pressure therapy. It combines responsive pressure delivery with user-friendly controls and comprehensive data tracking.
This review will walk you through the essential features, performance capabilities, and practical considerations of the DreamStation 2 Auto CPAP Advanced, helping you determine whether it’s the right fit for your sleep apnea therapy needs.
Philips DreamStation 2 Product Size and Design
The Philips Respironics DreamStation 2 Auto CPAP Advanced features a compact, modern footprint that fits comfortably on most bedside tables. The complete system with integrated heated humidifier measures approximately 26cm long, 15cm wide, and 11cm tall.
Weighing around 1.36kg with the humidifier attached, it’s one of the lighter full-featured CPAP machines available. You can easily move it between rooms or pack it for travel without adding significant weight to your luggage.
The redesigned aesthetic features smooth, rounded edges and a matte finish that looks less clinical than traditional medical devices. The touchscreen display sits flush with the front panel, contributing to the streamlined appearance.
It won’t stand out awkwardly in your bedroom. Most people describe it as looking more like a tech gadget than a medical device.
The humidifier chamber sits underneath the machine and slides out from the side for easy filling and cleaning. This side-loading design makes daily maintenance simpler than top-loading chambers on older models.
DreamStation 2 Auto Advanced CPAP Performance
The Philips DreamStation 2 Auto delivers pressure ranging from 4cm H2O to 20cm H2O. This auto-adjusting machine continuously monitors your breathing and adjusts pressure throughout the night to maintain open airways while using the lowest effective pressure at any given moment.
The machine operates remarkably quietly, with noise levels around 27 decibels at 10cm H2O pressure. That’s quieter than a whisper and comparable to rustling leaves. Both you and your sleeping partner can rest without disruption from machine noise.
The advanced algorithm behind the auto-adjusting pressure delivery responds within seconds when it detects breathing issues. When the algorithm identifies an obstruction or a shift in breathing patterns, it increases pressure to the level necessary to clear the airway. Once this optimal pressure is reached, the machine maintains that level to provide a consistent “splint” for your airway, ensuring it stays open and preventing further events from occurring.
This intelligent responsiveness means the machine finds the right therapeutic level for your specific needs each night. By establishing and holding the necessary pressure to keep your airway stable, the machine eliminates the guesswork of fixed-pressure therapy and provides a more secure, reliable sleep experience.

Key Features of the DreamStation 2 Auto CPAP
The DreamStation 2 Auto CPAP Advanced includes the standard features you’d expect from a modern CPAP machine. But the real difference comes from the thoughtful design choices that make nightly therapy easier to maintain over months and years.
Auto-Adjusting Pressure Delivery with Advanced Algorithm
Auto-adjusting CPAP machines adapt to your changing needs throughout the night as your required pressure varies. Sleep position, sleep stage, congestion, and alcohol consumption all affect your airway resistance.
The DreamStation 2’s algorithm continuously analyzes your breathing pattern and adjusts pressure to find the ideal therapeutic level. If you roll onto your back and your airway becomes more restricted, the machine responds by increasing pressure until the obstruction is cleared. Rather than fluctuating back and forth, the machine then holds that higher pressure to ensure your airway remains stable and protected for the remainder of the night.
This intelligent pressure management ensures you reach the specific therapeutic threshold required for your body on any given night. By finding the optimal pressure to prevent further collapses, the machine provides a more customized and secure experience than a standard fixed-pressure CPAP, which may not reach the levels needed during your most vulnerable sleep stages.
Intuitive Touchscreen Display with Simple Menu Navigation
The color touchscreen on the front of the machine replaces the dial-and-button interface found on the original DreamStation.
Navigation feels intuitive, allowing you to swipe and tap like you would on a smartphone.
The menu structure keeps things simple. Main options appear on the home screen: start therapy, adjust settings, view sleep data, check humidifier level.
You won’t need to dig through multiple submenus to find basic functions.
An ambient light sensor automatically adjusts screen brightness based on room lighting.
When you turn off the lights to sleep, the display dims to near-darkness so it won’t disturb you. If you need to check something during the night, the screen brightens just enough to see clearly without being harsh.
For people who prefer minimal light, you can manually adjust brightness levels or turn the display off entirely during therapy.
Integrated Heated Humidification with Climate Control
Dry, irritated airways are one of the most common complaints with CPAP therapy. The built-in heated humidifier adds warmth and moisture to the incoming air, helping prevent dry mouth, nasal congestion, and throat irritation.
You can adjust humidity levels from 1 to 5, with higher settings delivering more moisture. The machine also offers adaptive humidity mode, which automatically adjusts moisture output based on ambient temperature and humidity in your room.
The redesigned humidifier chamber holds enough water for a full night at moderate settings. The side-loading design makes filling easier. You don’t need to detach tubes or lift the machine.
Just slide out the chamber, fill to the max line with distilled water, and slide it back in.
A preheat function warms the water before you start therapy, so you’re comfortable from the first breath. The heated tube option (sold separately) further reduces condensation and “rainout” by maintaining consistent temperature from the machine to your mask.
Flex Technology for Pressure Relief
Philips’ Flex technology provides pressure relief when you exhale, making breathing feel more natural. The machine slightly reduces pressure at the beginning of exhalation, making it easier to breathe out against the incoming air.
You can adjust Flex settings in three levels (1, 2, or 3) or turn it off completely. Most users find level 2 or 3 provides noticeable comfort improvement without compromising therapy effectiveness.
This feature is particularly helpful during the adjustment period when you’re getting used to CPAP therapy. Even small amounts of pressure relief can make the difference between tolerating therapy and giving up on it.
Ramp Feature for Easier Sleep Onset
Falling asleep with full pressure can be challenging, especially for new CPAP users.
The ramp feature gradually increases pressure from a lower starting point to your prescribed level over a set time period.
You can adjust ramp time from 0 to 45 minutes in 5-minute increments.
The machine starts at a comfortable lower pressure and reaches full pressure by the time you’re asleep.
The touchscreen makes adjusting ramp time easy. You can change it night by night based on how tired you are or whether you’re having trouble falling asleep.
Advanced Event Detection and Response
The machine continuously monitors multiple breathing parameters throughout the night. It tracks:
- Apnea events (complete breathing pauses)
- Hypopnea events (partial airflow reduction)
- Flow limitations (restricted breathing)
- Snoring
- RERAs (respiratory effort-related arousals)
When the algorithm detects any of these issues, it responds by adjusting pressure to restore normal breathing. The response happens within seconds, often clearing the obstruction before it fully disrupts your sleep.
This real-time monitoring and adjustment is what makes auto CPAP effective, treating breathing problems as they happen rather than using one fixed pressure all night.
Auto On/Off and Smart Convenience Features
The DreamStation 2 includes several features that eliminate unnecessary button-pressing:
- Auto Start begins delivering pressure as soon as you breathe through the mask. Put on your mask, take a breath, and therapy starts automatically. No fumbling for power buttons when you’re ready to sleep.
- Auto Stop turns off therapy when you remove your mask in the morning or during the night. The machine senses the pressure drop and stops within seconds.
- Mask Fit Check delivers airflow while you adjust your mask and provides real-time feedback on the screen. Green indicators show you’ve got a good seal. Yellow or red indicates leaks that need adjustment.
These automation features make the nightly routine simpler, especially valuable when you’re tired and just want to get to sleep.
Bluetooth Connectivity and DreamMapper App
Built-in Bluetooth connects the machine to Philips’ free DreamMapper app (available for iOS and Android). The app syncs your therapy data each morning and displays it in an easy-to-understand format.
You can view:
- Hours used each night
- AHI (apnea-hypopnea index or the number of breathing events per hour)
- Mask leak rates
- Pressure levels throughout the night
- 30-day compliance tracking
The app breaks down complex sleep data into simple graphs and trends, including the hours you use the machine each night, apnea-hypopnea index (AHI), mask leak rates, pressure levels throughout the night, and your 30-day compliance tracking.
This makes it easy to see how changes to your routine (sleeping position, alcohol consumption, weight loss) affect your therapy results.
Daily Progress Feedback appears on the machine’s screen each morning, showing whether you met the 4-hour minimum for insurance compliance. Green indicates successful nights, helping you stay on track for the typical requirement of 21 compliant nights over 30 days.
Your healthcare provider can also access detailed therapy reports to monitor your progress and make adjustments to your prescription if needed.
System One Resistance Control
If you use a Philips Respironics mask, the machine can automatically recognize your specific mask type.
Different mask designs create different amounts of resistance as air flows through them. System One Resistance Control accounts for these differences, improving therapy accuracy.
This feature only works with Philips Respironics masks.
Masks from other manufacturers don’t include the resistance coding that the machine reads. However, the machine will still deliver effective therapy without this automatic mask-specific calibration.
Considerations
The DreamStation 2 Auto CPAP Advanced delivers strong performance and user-friendly features, but there are a few practical considerations worth knowing:
Touchscreen Learning Curve
If you’re upgrading from a button-based machine, the touchscreen interface takes a few days to get used to.
Some users prefer the tactile feedback of physical buttons, especially when adjusting settings in the dark.
The learning curve is short, but it exists.
Humidifier Capacity
The water chamber is compact, which contributes to the machine’s smaller footprint.
Depending on your humidity settings and room environment, you might occasionally wake up to an empty chamber.
If you run humidity at level 4 or 5 in a dry climate, consider refilling before bed or reducing the humidity setting slightly.
DreamStation-Specific Parts
Replacement accessories need to be compatible with DreamStation 2 specifically. Even parts from the original DreamStation may not work with the newer model.
Double-check compatibility when ordering filters, chambers, or other components.
