Choosing the right CPAP mask is the single most important factor in staying compliant with your sleep apnea therapy. In the Australian market, two heavyweights currently dominate the “minimalist” category: the ResMed AirFit F40 and the Fisher & Paykel (F&P) Evora Full.
Both masks aim to solve the common complaints of traditional full face masks—bulkiness, leaks into the eyes, and bridge-of-the-nose sores. But when it comes down to ResMed AirFit F40 vs. Fisher & Paykel Evora, which one actually delivers a better night’s sleep? This in-depth comparison breaks down the technology, fit, and real-world performance to help you decide.

What is a Minimalist Full Face Mask?
A minimalist full face mask, also known as an “under-the-nose” full face mask, provides therapy to both the nose and mouth without covering the bridge of the nose. By sealing against the nostrils from underneath and covering the mouth, these masks eliminate the heavy T-zone frame that often causes skin irritation and blocks your field of vision.
The ResMed AirFit F40: The New Challenger
The AirFit F40 is ResMed’s newest ultra-compact full face mask. It is designed to be their softest and most adaptable mask yet, featuring the AdaptiSeal™ 100% silicone cushion. It removes the rigid plastic frame entirely, allowing the mask to contour to various face shapes with minimal pressure.
The Fisher & Paykel Evora Full: The Established Favourite
The Evora Full brought “Dynamic Support Technology” to the forefront. It uses “Stability Wings” and a “Floating Seal” to maintain a secure fit even as you move. It is widely praised for its breathable headgear and its ability to handle higher pressure settings without losing its seal.
Head-to-Head: Key Features Comparison
To understand which mask wins, we need to look at the technical specifications and design choices that impact your daily use.

| Magnets | Yes (Quick-fit) | No (Clip-fit) |
| Best For | Side sleepers & sensitive skin | High pressure & magnetic contraindications |
In-Depth Comparison: Comfort and Seal
1. Cushion Technology and Skin Comfort
The ResMed AirFit F40 wins on pure softness. Because the entire cushion is made of pliable silicone without a hard internal frame, it “squishes” against the face comfortably. This makes it an excellent choice for side sleepers who often find that their pillow pushes the mask out of place.
The F&P Evora Full, however, feels more “secure.” The Stability Wings provide a structural backbone that prevents the mask from collapsing. If you have a particularly active sleep style or use high therapy pressures (above 15 cmH2O), the Evora’s structured seal often holds up better than the ultra-soft F40.
2. Quietness and Partner Disturbance
In the battle of the bedroom environment, the AirFit F40 is the clear victor. Featuring QuietAir™ technology, it operates at roughly 20 dBA—which is quieter than a ticking watch. The air is diffused so gently that your partner won’t feel a “jet stream” of air hitting them. The Evora is by no means loud, but its laser-drilled vents are more audible at approximately 28 dBA.
3. Ease of Use: Magnets vs. Clips
ResMed utilizes magnetic clips, which are incredibly easy to snap on and off in the dark. However, this is a double-edged sword.
Expert Note: If you or your bed partner have a pacemaker, ICD, or other metallic implants, the ResMed AirFit F40 may be contraindicated. In these cases, the F&P Evora Full is the safer choice as it uses non-magnetic plastic clips.
Real-World Use Cases: Which Should You Choose?
Choose the ResMed AirFit F40 if:
- You are a side sleeper: The flexible frame won’t dig into your face when pressed against a pillow.
- You have sensitive skin: The lack of hard plastic reduces the risk of pressure sores.
- You want the quietest experience: Ideal for light sleepers and their partners.
- You wear glasses: The ultra-low profile provides a completely unobstructed view for reading.
Choose the Fisher & Paykel Evora if:
- You have a medical implant: No magnets means zero interference with pacemakers.
- You use high pressure: The “Stability Wings” keep the seal intact when the air pressure ramps up.
- You get hot at night: The VentiCool™ headgear is superior at wicking away moisture and heat compared to standard fabric straps.
- You prefer a “locked-in” feel: The structured frame offers more stability for restless sleepers.
Step-by-Step: How to Ensure a Perfect Fit
Regardless of which mask you choose, the following framework will help you achieve the best results:
- Size Correctially: Use the manufacturer’s sizing template. For the Evora, many Australian retailers offer a “Fit Pack” which includes multiple cushion sizes (XS, S-M, L) in one box.
- Fit While Lying Down: Your face shape changes when you lie down. Always do your final strap adjustments in your sleeping position with the machine turned on.
- Don’t Overtighten: If you have to pull the straps tight enough to cause pain to get a seal, you likely have the wrong cushion size or a mismatch in mask shape.
- Use a CPAP Pillow: If you are a side sleeper, a dedicated CPAP pillow with cut-outs can prevent either the F40 or Evora from being dislodged during the night.
Common Mistakes to Avoid
- Ignoring Magnet Warnings: Always check your medical history before buying the AirFit F40.
- Setting the Wrong Mask Type: Ensure your CPAP machine is set to “Full Face.” On ResMed machines, the F40 actually performs best on the “Pillows” or “Ultra-Compact” setting—check your manual for the 2026 updated firmware settings.
- Using Old Cushions: Even the best silicone degrades. Replace your F40 or Evora cushion every 3–6 months to maintain the seal.
FAQ: ResMed AirFit F40 vs. Fisher & Paykel Evora
Is the ResMed AirFit F40 better for side sleepers?
Yes. Its 100% silicone frame is more flexible than the Evora’s structured frame, making it more forgiving when pressed against a pillow.
Does the F&P Evora Full have magnets?
No. The Evora uses plastic hook-and-clip connectors, making it safe for users with pacemakers or other metallic implants.
Which mask is quieter?
The ResMed AirFit F40 is significantly quieter (20 dBA) compared to the F&P Evora (28 dBA) thanks to the QuietAir™ diffusion vent.
Can I wear glasses with these masks?
Yes, both are “minimalist” designs that sit under the nose, leaving the bridge of the nose and the eyes completely clear.
Will these masks work with my existing CPAP machine?
Yes. Both the AirFit F40 and F&P Evora use standard 22mm tubing connections, making them compatible with ResMed AirSense, Philips DreamStation, and F&P SleepStyle machines.
Conclusion: The Verdict
In the debate of ResMed AirFit F40 vs. Fisher & Paykel Evora, there is no single “best” mask, but there is a best mask for you.
The ResMed AirFit F40 is the gold standard for comfort and quietness. If you want a mask that feels like it’s barely there and you don’t have medical contraindications for magnets, it is the winner.
However, the Fisher & Paykel Evora remains the champion of stability and safety. For those with pacemakers, high-pressure requirements, or a tendency to “run hot” at night, the Evora’s VentiCool technology and rigid support wings make it a more reliable workhorse.
