Frequently Asked Questions

The InfinitySeal cushion features adaptive technology that molds to your unique facial contours, creating a personalized seal that maintains effectiveness throughout the night. Unlike traditional cushions with fixed shapes, the InfinitySeal adapts to facial movements and changes in sleeping position.
This technology provides 99.4% compatibility across different facial types, significantly reducing the need for multiple fitting attempts and ensuring optimal therapy from the first night.
The AirFit N20 For Her features the same InfinitySeal technology but with design elements specifically tailored for women:
- Softer color palette: Lavender and pink accents instead of blue
- Smaller headgear: Proportioned for typically smaller head sizes
- Refined aesthetics: More delicate design elements
- Same performance: Identical seal technology and effectiveness
Both versions are available in all cushion sizes and offer the same clinical performance and comfort features.
The AirFit N20's InfinitySeal technology is designed to accommodate a wide range of facial features, but proper sizing is still important:
Small
Narrow nasal bridge, petite facial features
Medium
Average nasal bridge, most common size
Large
Wide nasal bridge, larger facial features
Our team provides professional fitting assistance to ensure you receive the optimal size for your facial structure.
The AirFit N20 is specifically designed for nasal breathing and covers only the nose. If you're a mouth breather, you may experience:
- Air leakage through the mouth
- Reduced therapy effectiveness
- Dry mouth symptoms
- Potential therapy interruptions
Recommended alternatives for mouth breathers:
- AirFit F30i: Full face mask covering nose and mouth
- Chin strap: Used with N20 to keep mouth closed
- Mouth tape: Medical tape to encourage nasal breathing
Consult with your sleep specialist to determine the best solution for your breathing patterns.
Regular replacement ensures optimal performance and hygiene:
InfinitySeal Cushion
Replace every 1-2 months or when seal effectiveness decreases.
Plush Headgear
Replace every 6 months or when straps lose elasticity.
