Choosing the right BiPAP machine can feel overwhelming. With a wide range of models offering different pressure modes, comfort technologies and price points, it's easy to get lost in the specifications. This guide cuts through the noise by ranking the best BiPAP (BiLevel) machines available on CPAPeuropa.com — from ResMed's flagship AirCurve series to specialised ventilators and value-focused BMC models. We've weighed features, therapy modes, comfort and price to help you make an informed choice. Remember: a BiPAP device is a prescription therapy, so use this guide to shortlist candidates, then confirm the right model with your doctor or sleep specialist.
What Is a BiPAP Machine?
A BiPAP (Bilevel Positive Airway Pressure) machine — also written BiLevel or BPAP — delivers two different air pressures: a higher pressure when you breathe in (IPAP) and a lower pressure when you breathe out (EPAP). This is the key distinction from a standard CPAP machine, which holds a single constant pressure throughout the breathing cycle. The lower exhalation pressure makes breathing out against the airflow noticeably easier, which is why BiPAP is often prescribed for people who need higher pressures, find CPAP uncomfortable, or have conditions that require ventilatory support beyond simple airway splinting.
BiPAP therapy is commonly used for obstructive sleep apnea at higher pressure requirements, for certain respiratory and neuromuscular conditions, for COPD-related hypoventilation, and — in specialised modes — for central and complex sleep apnea. Because the appropriate device and mode depend entirely on your diagnosis and prescription, the "best" BiPAP machine is the one that matches your clinical needs. The ranking below reflects overall value, technology and comfort across the CPAPeuropa range.
How We Ranked These BiPAP Machines
Our ranking balances several factors rather than fixating on price alone. We considered the sophistication of each device's pressure algorithm, comfort features such as humidification and pressure relief, ease of use, data tracking, reliability and the value each machine offers at its price. Specialist ventilators serving specific clinical needs are included and ranked on their merits within their category. The result is a practical shortlist covering every budget and therapy requirement.

BiPAP Modes Explained: S, ST, VAuto, ASV & iVAPS
Much of the price and capability difference between these machines comes down to the therapy mode they offer. Here's what the acronyms mean in practice — your prescription will specify which one you need.
S — Spontaneous (Fixed BiLevel)
Delivers two fixed pressures — higher on inhale (IPAP), lower on exhale (EPAP) — triggered by your own breathing. Simple, reliable and the entry point to BiLevel therapy, as seen on the AirCurve 10 S.
ST — Spontaneous/Timed
Adds a backup respiratory rate: if you don't initiate a breath within a set time, the device delivers one for you. Useful where consistent breathing support is needed, as on the Lumis 150 VPAP ST.
VAuto — Auto-Adjusting BiLevel
Automatically adjusts the pressures night to night and moment to moment based on your airway, combining BiLevel comfort with auto-titration. The technology behind our top picks, the AirCurve 11 and 10 VAuto.
ASV — Adaptive Servo-Ventilation
A specialised mode that adjusts support breath-by-breath to stabilise irregular breathing. Prescribed for central and complex sleep apnea and Cheyne-Stokes respiration, as on the AirCurve 10 CS PaceWave.
iVAPS — Intelligent Volume-Assured Pressure Support
Targets a set level of ventilation and automatically varies pressure support to maintain it, adapting to your needs over the night. Found on the Lumis 150 and RESmart Y-30T for more complex ventilatory support.
Volume-Targeted (VT)
Aims to deliver a consistent tidal volume by adjusting pressure as needed, as reflected in the BMC G3 B30VT. A budget-friendly route to adaptive, volume-oriented support with integrated humidification.
How to Choose the Right BiPAP Machine
The best BiPAP for you is defined first by your prescription, then by comfort and budget. These are the factors that should guide your shortlist.
- Start with your prescribed mode. If your doctor specified ASV or iVAPS, only devices offering that mode will do — this immediately narrows the field. For standard higher-pressure OSA, a VAuto or S device is typically appropriate.
- Prioritise comfort features. Integrated humidification, pressure relief on exhalation and quiet operation make a real difference to nightly adherence — and adherence is what makes therapy work.
- Consider data and connectivity. App-based tracking (such as ResMed's myAir) helps you and your clinician monitor progress and fine-tune therapy over time.
- Match the machine to your budget honestly. Value models like the BMC G3 range and RESmart devices deliver the essentials at a lower price; flagship ResMed units add refined algorithms, build quality and ecosystem support.
- Think about travel. If you travel often, size, weight and ease of setup matter — some ventilators are surprisingly portable, but always check power and cabin-use details.
BiPAP vs CPAP: What's the Difference?
| Feature | CPAP | BiPAP (BiLevel) |
|---|---|---|
| Pressure | One constant pressure | Two pressures — higher on inhale, lower on exhale |
| Exhaling comfort | Can feel harder against constant pressure | Easier — pressure drops when you breathe out |
| Typical use | Most obstructive sleep apnea | Higher-pressure OSA, CPAP intolerance, ventilatory support |
| Specialist modes | Fixed / Auto (APAP) | S, ST, VAuto, ASV, iVAPS |
| Price range | Generally lower | Generally higher, reflecting added capability |
💡 In short: If standard CPAP controls your apnea comfortably, you likely don't need a BiPAP. BiLevel therapy becomes valuable when pressures are high, when exhaling against CPAP is difficult, or when your condition calls for a mode CPAP simply doesn't offer. Your sleep study and clinician determine which is right.
Your BiPAP Buying Journey
⚠️ Prescription required: BiPAP machines are prescription medical devices. The settings and mode must be configured to your individual prescription, and the right choice depends on your diagnosis. Always confirm your device and settings with your doctor or sleep specialist before purchase and use.
Frequently Asked Questions
Which is the best BiPAP machine overall?
Our top pick is the ResMed AirCurve 11 VAuto (€1,900). As ResMed's latest BiLevel device, it combines an advanced auto-adjusting algorithm, integrated humidification, quiet operation, a colour touchscreen and myAir data tracking at a competitive price. That said, the "best" machine depends on your prescribed mode — for specialist needs like central apnea, a device such as the AirCurve 10 CS PaceWave ASV may be the right choice instead.
What's the difference between BiPAP and CPAP?
CPAP delivers a single constant pressure, while BiPAP delivers two — a higher pressure when you inhale (IPAP) and a lower one when you exhale (EPAP). The lower exhalation pressure makes breathing out easier, which is why BiPAP is often used at higher pressures, for CPAP intolerance, or when ventilatory support is needed beyond what CPAP provides.
Do I need a prescription to buy a BiPAP machine?
Yes. BiPAP machines are prescription medical devices, and both the mode and pressure settings must be configured to your individual prescription. Use this guide to shortlist suitable devices, but confirm the specific model and settings with your doctor or sleep specialist before buying.
What is the most affordable BiPAP machine?
The BMC G3 B25A (€999) is the most affordable premium BiPAP on our list. It offers a modern interface, adjustable pressure settings and integrated humidification, making quality BiLevel therapy accessible at a lower price. The BMC G3 B30VT (€1,399) and RESmart GII 25T (€1,500) are strong value options a step up.
Which BiPAP machine treats central sleep apnea?
For central and complex sleep apnea, including Cheyne-Stokes respiration, an ASV (adaptive servo-ventilation) device is typically required. On our list, that's the ResMed AirCurve 10 CS PaceWave ASV (€4,500), which adjusts pressure support breath-by-breath. ASV is prescribed for specific conditions, so it must be recommended and configured by your specialist.
What do VAuto, S, ST, ASV and iVAPS mean?
These are BiPAP therapy modes. S provides two fixed pressures triggered by your breathing; ST adds a timed backup rate; VAuto auto-adjusts the pressures through the night; ASV stabilises irregular breathing breath-by-breath for central apnea; and iVAPS targets a set ventilation level and varies pressure support to maintain it. Your prescription specifies which mode you need.
Are BiPAP machines suitable for travel?
Many are. Several devices on this list are compact enough for transport, and even specialist ventilators like the Lumis 150 VPAP ST are relatively portable for their category. If you travel frequently, check the device's weight, power supply compatibility and any airline requirements, and consider a dedicated travel setup where available.
