AirFit N20 versus Nova Nasal
|
|
In this comparison, Clay from CPAPmyway evaluates whether the all-new Fisher & Paykel Nova Nasal can unseat the ResMed AirFit N20, which has long been considered the most ubiquitous nasal mask on the market. By diving into key differences in weight, noise levels, and seal performance at high pressures, this guide helps you determine if the modern features of the Nova warrant a switch from the tried-and-true N20.
In this blog we compare:
Design and Weight: Both are traditional nasal masks with an open line of sight, but the Nova is significantly lighter at 1.4 oz, whereas the N20 weighs 2.85 oz.
Noise and Airflow: The Nova operates at a quieter 21 dB and features a diffuser that eliminates exhalation draft, while the N20 is slightly louder at 23 dB with a more noticeable air draft.
Seal and Pressure Performance: While both masks successfully maintained a seal up to 20 cm of pressure during testing, the N20 uses a firmer "Infinity Seal" silicone compared to the softer, more collapsible "RollFit" cushion on the Nova.

AirFit N20 Versus Nova Nasal Review
Specification Comparison of N20 and Nova Nasal
Side-by-Side: The "Spec Shootout"
Comparison: ResMed AirFit N20 vs. F&P Nova Nasal
- Weight: The Nova is ultra-lightweight at 1.4 oz , while the N20 is over twice as heavy, weighing in at 2.85 oz.
Noise Level: The Nova is slightly quieter at 21 dB due to its exhalation diffuser , compared to the N20 at 23 dB.
Cushion Tech: The N20 uses a firm, tacky silicone called the Infinity Seal. The Nova features the RollFit cushion, which is soft and collapsible from start to finish.
Performance & Benefits:Testing both masks at a maximum CPAP pressure of 20 cm revealed that both are highly capable of maintaining a seal.
The "Fit Pack" Advantage:Unlike the N20, which must be purchased in unique sizes , the Nova is available as a fit pack. This is a major benefit for new users still figuring out their ideal cushion size.

Live Performance & Comfort: The Real-World Test
In a side-by-side pressure test using an AirSense 10, both masks proved their reliability by maintaining a solid seal all the way up to 20 cm. While the ResMed AirFit N20 continues to hold its own as a "tried-and-true" favorite, the Fisher & Paykel Nova Nasal introduces several modern refinements designed for enhanced user comfort.
Performance at High Pressure
Nova Nasal: Remained completely silent with no leaks at standard pressures. At the maximum 20 cm setting, it required only a minor adjustment to the top and bottom straps to stay secure.
AirFit N20: Successfully reached 20 cm of pressure on the test, though it did require tightening along the cheek area to manage a slight leak at that extreme level.
"If you're going for quiet, light, and no exhalation draft, this Nova is an easy win. But the tried-and-true N20 is definitely still holding its weight."
Sleep Quality Factors
The "Bed Partner" Test: The Nova features an advanced exhalation diffuser that makes it "darn near silent" and eliminates the draft of air. In contrast, the N20 has a noticeable exhalation draft that can be felt up to 2 feet away, which may be a consideration for sensitive bed partners.
Ergonomics for Side Sleepers: The N20 utilizes magnetic clips that sit directly on the jawline, which can sometimes press into a pillow. The Nova offers a slimmer profile with connections positioned further back, reducing bulk on the side of the face.
Tubing Versatility: A unique feature of the Nova is its headgear clip, which allows you to route the tubing over the top of your head toward the headboard. The N20 uses a standard front-facing tube connection.
Full Face CPAP Mask options
The Fisher & Paykel Nova Nasal is an ultra-lightweight traditional mask designed for a quiet, streamlined experience.
Nova Key Features

The Final Verdict: Nova Nasal vs N20
- Choose the Nova Nasal if: You want a mask that is more than twice as light, operates silently without a draft, or if you need a mask without magnets due to a pacemaker.
Choose the AirFit N20 if: You prefer a firmer, tackier "Infinity Seal" or if you have successfully used this classic design for years and prefer the quick-snap convenience of magnets.
Risk-Free Trial: If you aren't sure which one is right for you, we offer a 30-day guarantee. You can try the Nova Nasal, and if it isn't the perfect fit, you can easily switch to the N20 with no risk.
