How often should I change my cpap filters?

Reusable filters should be replaced every 6 months and disposable filters should be replaced every 2 weeks. If filters are damaged or very dirty, they should be replaced more often.

Key Factors Affecting Filter Replacement

·       Age of filter: The general rule of thumb is to replace disposable filters every 2 weeks and reusable filters every 6 months. Be sure to have plenty of spare filters so you can keep up with the schedule.

·       Environment: If you live in a dusty area, have pets, or smoke tobacco, it may be necessary to change filters more often than recommended. It’s important to check our filters periodically for debris or dirt that could reduce airflow.

·       Wetness: Be sure your reusable filter is completely dry before putting it back into your machine. You should have a spare reusable filter on hand to put in your machine after removing and washing your main filter so that it has plenty of time to dry before you use it again.

·       Damage: If you notice tears or holes in your filter, you should replace it right away. Filters that don’t fit snugly into place could allow debris into the air path of your machine and should be thrown away.

Always have spare filters on hand so that you can change them regularly. Some retailers such as CPAP Z offer subscription programs that automatically deliver new filters so you can stay on schedule.
