A CPAP machine is a long-term investment in your health. With several device types and dozens of models available, the options can be confusing. However, the right choice comes down to a few key factors: your prescription, your lifestyle, and the features that will keep you compliant with therapy over the long term. This guide explains what to look for so you can make a confident, informed decision.
Understanding Your Prescription First
Before comparing devices, understand what your sleep specialist prescribed. Your prescription specifies the device type and pressure range. Not all CPAP devices are interchangeable, and choosing the wrong type will not treat your sleep apnea effectively.
CPAP Device Types Explained
| Device Type | How It Works | Best For |
|---|---|---|
| CPAP | Fixed pressure — one setting all night | Mild to moderate OSA, stable pressure needs |
| APAP (Auto CPAP) | Adjusts pressure automatically in real time | Varying pressure needs, most common choice |
| BiPAP | Two pressure levels — higher inhale, lower exhale | Higher pressure prescriptions, central sleep apnea |
CPAP Machines
A standard CPAP machine delivers a single fixed pressure throughout the night. Your sleep specialist sets the pressure based on your sleep study results. The ResMed AirSense 10 Elite, available through CPAP Central’s products page, is a fixed-pressure CPAP with an integrated heated humidifier, cellular connectivity for remote monitoring, and advanced event detection. It is one of the most widely used devices in Canada.
APAP Machines
An APAP, or automatic positive airway pressure machine, adjusts its pressure from breath to breath based on detected airway resistance. This means the device delivers the minimum pressure needed at any given moment rather than maintaining a constant level. Many patients find APAP more comfortable, particularly during the early weeks of therapy.
APAP devices also collect detailed therapy data, making it easier for your clinical care specialist to review your progress and fine-tune your settings during follow-up appointments.
BiPAP Machines
A BiPAP machine delivers two distinct pressure levels: a higher pressure during inhalation and a lower pressure during exhalation. The ResMed AirCurve is CPAP Central’s BiPAP offering, designed for patients prescribed bilevel therapy. It includes integrated humidification and therapy data tracking. See our products page for details.
Key Features to Consider
Humidification
Dry air from a CPAP machine can cause nasal congestion, dry mouth, and throat irritation. An integrated heated humidifier addresses this. Most modern devices include a humidifier chamber. Heated tubing further reduces condensation and improves comfort throughout the night.
Noise Level
Modern CPAP machines are significantly quieter than older units. Most operate at around 25 to 30 decibels, which is roughly the level of a whispered conversation. If noise is a concern for you or your sleep partner, check the device’s decibel rating before purchasing.
Data Tracking and Remote Monitoring
Devices with cellular connectivity, like the ResMed AirSense 10 Elite, allow your clinical care team to monitor your therapy data remotely. This means CPAP Central can identify issues between appointments and make pressure adjustments while you are on the phone, without requiring a clinic visit.
Ramp Feature
The ramp feature starts therapy at a lower pressure and gradually increases to your prescribed level over a set period. This helps you fall asleep before the full pressure kicks in. Most patients find it easier to adjust to therapy when the ramp feature is enabled.
Size and Portability
If you travel frequently, the size and weight of your device matter. Standard CPAP machines are bedside units. If portability is a priority, consider whether a travel CPAP like the ResMed AirMini would complement your primary device.
ADP Funding and Insurance
Ontario residents with a valid sleep apnea diagnosis qualify for an ADP grant of $415.50 toward a CPAP machine, or $712.50 toward a BiPAP. CPAP Central is an ADP-authorized vendor. Our funding team handles the application process and direct billing with your private insurer. Get started by submitting our insurance pre-approval form before your appointment.
Why Your Choice of Vendor Matters
A CPAP machine purchased without proper fitting, follow-up, and clinical support often ends up unused. At CPAP Central, every patient goes through a structured trial phase that includes mask fitting, device setup, ongoing follow-up, and remote monitoring.
