CPAP Filters FAQs

What are the different types of 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.

How often should I replace my reusable CPAP filters?

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.

What is the recommended replacement schedule for disposable fine filters?

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.

Can I wash and reuse disposable CPAP filters?

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.

How do I find the right filters for my specific CPAP machine?

To find the appropriate filters for your CPAP machine, you can:

  • Use our replacement part finder quiz on CPAP.com to quickly identify compatible filters for your specific machine model.
  • Check your machine's user manual or the manufacturer's website for a list of recommended filter types and part numbers.
  • Contact our knowledgeable customer support team for assistance in selecting the correct filters for your CPAP machine.

CPAP Filters are great for:

  • Maintaining clean, healthy air quality. CPAP filters trap dust, allergens, and other particles, ensuring that the air you breathe during therapy is clean and free from irritants.
  • Protecting your CPAP machine. By preventing debris and contaminants from entering your machine, filters help extend its lifespan and maintain optimal performance.
  • Enhancing your therapy experience. Clean filters contribute to a more comfortable and effective CPAP therapy experience by providing fresh, filtered air and reducing the risk of respiratory irritation.
  • Customizing your filtration level. With options like reusable foam, disposable fine, and bacteria filters, you can choose the level of filtration that best suits your needs and preferences.
  • Ensuring uninterrupted therapy. Keeping a supply of replacement filters on hand allows you to quickly swap out dirty or worn filters, minimizing any disruptions to your nightly CPAP therapy routine.
