CPAP Filters

There are three main types of CPAP filters:

• Reusable foam filters: These filters can be washed and reused, typically lasting up to 6 months before needing replacement.
• Disposable fine filters: These filters provide a higher level of filtration but need to be replaced more frequently, usually every 30 days.
• Bacteria filters: Offering the highest level of defense against harmful particles, bacteria filters help maintain the cleanliness and air quality of your CPAP therapy.

Reusable foam filters should be replaced every 6 months or sooner if they begin to show signs of wear or damage. It's essential to follow a regular replacement schedule to ensure your CPAP machine continues to deliver clean, filtered air.

Disposable fine filters should be replaced every 30 days or as soon as they start to appear worn or dirty. These filters provide a higher level of filtration than reusable foam filters, so timely replacement is crucial for maintaining air quality and protecting your lungs.

No, disposable CPAP filters are designed for single use and should not be washed or reused. Attempting to clean or reuse these filters can damage their filtration capabilities and compromise the air quality of your CPAP therapy. Always replace disposable filters according to the recommended schedule.
