Reusable Foam Filter for System One

Foam Filter for the System One and M Series Machines

The Reusable Foam Filter by Philips Respironics for the System One and M Series Machines is a high-performance tool designed to prevent debris, dust, and other particles from clogging up your device and compromising your results. This foam filter comes in a pack of two and, if properly cleaned and maintained, can last up to 3 months. These reusable Respironics filters are straightforward and remarkably easy to apply - with regular maintenance, you'll be able to enjoy dust-free air during your therapy session.

Washable and Reusable

In order to maximize both the lifespan of your Respironics System One filters and your therapy results, it's imperative you clean your filter on a regular basis. To clean, wash your filter with a mild detergent and dry it with a paper towel - be sure not to twist the filter when drying with the towel. It is strongly recommended that you replace the foam filter after 3 months, as even properly maintained filters lose their effectiveness over time.

  • Should be washed routinely for optimal performance
  • Can be reused up to 2-3 times

Pretty surprised with the discount code you gave me. Thanks by the way, lisa. Saved me a couple of dollars. I love this filter. It's cheap and reusable plus good quality. I have been using this same filter for a year now.
