When it comes to choosing the right CPAP mask, one of the most crucial factors is ensuring the correct size for optimal comfort and effectiveness during sleep therapy. The AirFit N20, a popular nasal mask from ResMed, is designed to provide a comfortable and effective fit for a wide range of users. In this comprehensive AirFit N20 sizing guide, we will explore the importance of proper sizing, how to measure for the right fit, and tips for achieving the best results with your mask.
Understanding the Importance of Proper Sizing
A well-fitted CPAP mask is essential for several reasons:
1. Comfort: An ill-fitting mask can lead to discomfort, skin irritation, and pressure sores. Proper sizing ensures that the mask sits securely on your face without causing pain.
2. Seal: The effectiveness of your CPAP therapy largely depends on the mask's ability to create a proper seal. A mask that is too small or too large can result in air leaks, leading to ineffective therapy and disrupted sleep.
3. Compliance: Many patients struggle with mask compliance. A comfortable, well-fitted mask is more likely to be worn consistently, improving the overall success of CPAP therapy.
4. Noise Reduction: A properly sized mask minimizes the chances of air leaks, which can create unnecessary noise, disturbing both the user and their sleeping partner.

How to Measure for the Right Size
To find the perfect size for your AirFit N20 mask, follow these steps:
Step 1: Gather Your Tools
You will need:
- A measuring tape or ruler
- A mirror
- A pen and paper to note down your measurements
Step 2: Measure Your Face
The sizing for the AirFit N20 is primarily based on the width of your nose and the distance from your nose bridge to the bottom of your chin. Here’s how to measure:
1. Nose Width:
- Use the measuring tape to measure the width of your nose at its widest point.
- Record the measurement in centimeters (cm).
2. Nose Bridge to Chin Distance:
- With your head in a neutral position, measure from the bridge of your nose (where the mask will sit) down to the bottom of your chin.
- Again, record this measurement in centimeters (cm).
Step 3: Determine Your Size
Referring to the following size chart based on your measurements will help determine your appropriate AirFit N20 size:
| Size | Nose Width (cm) | Distance (cm) |
|----------|------------------|----------------|
| Small | 2.5 - 3.5 | 10.0 - 12.0 |
| Medium | 3.5 - 4.5 | 12.0 - 14.0 |
| Large | 4.5 - 5.5 | 14.0 - 16.0 |
Using your measurements, identify which size corresponds best to your dimensions.
Trying on the AirFit N20 Mask
Once you have determined your size, it’s time to try on the AirFit N20 mask. Follow these steps for the best fit:
Step 1: Adjust the Headgear
- Loosely fit the headgear over your head without tightening it too much.
- Ensure the back of the headgear is secured and not slipping off.
Step 2: Position the Mask
- Place the mask over your nose and adjust it until it feels comfortable.
- Make sure the cushion sits snugly against your face without excessive pressure.
Step 3: Tighten the Straps
- Gradually tighten the headgear straps until you achieve a secure fit.
- Avoid overtightening, as this can lead to discomfort and pressure sores.
Step 4: Check for Leaks
- With the mask on, turn on your CPAP machine.
- Check for air leaks around the edges of the mask. If you notice leaks, make slight adjustments to the headgear until the leaks are minimized.
Step 5: Assess Comfort
- Spend a few moments wearing the mask while sitting up. It should feel comfortable and secure.
- If you experience significant discomfort or leaks, consider trying a different size or adjusting the headgear further.
Tips for Maintaining Your AirFit N20 Mask
