Learn About Reusable CPAP Filters

Reusable filters are foamy and designed to keep out larger particles like dirt and animal fur. Although reusable filters can washed, they still must be replaced as they wear out or every three months. If you are unsure about what filters to buy, use our part finder!

  • Catches larger particles

  • Lightly wash with a mild detergent biweekly

  • All CPAPs use at least one filter
