Recommended Replacement: 1 MonthUsers will multiple pets and dander may find bi-weekly replacement optimal.Replacing your AirSense 11 CPAP filter every month is important because it keeps the air you breathe clean and your therapy working properly. The filter traps dust, pollen, and other particles, but over time it becomes clogged and less effective, which can lead to poor air quality and even blow contaminants back toward you. A dirty filter can also restrict airflow, making your CPAP machine work harder and reducing the effectiveness of your treatment. This can cause symptoms like congestion, dry throat, or irritation, making the experience less comfortable and harder to stick with. On top of that, regularly changing the filter helps protect your machine from dust buildup and extends its lifespan. Overall, it’s a simple habit that improves comfort, performance, and consistency with your therapy.
