This Filter Cover snaps onto the back of all S9 CPAP/BiLevel Machines to cover the filter compartment. It will also help protect the device in the event of accidental liquid spillage. The filter and filter cover should be fitted at all times when using any ResMed S9 Machine.

  • The s9 filter cover is abysmal


    The S9 filter cover is flimsy, easily warps over time and entirely inadequate (*in my opinion*) to protecting the lifespan of this important and costly device. Indeed, I find myself wondering if it wasn't chosen to reinforce product obsolescence. Between the filter (which barely covers the air inlet) and the filter cover, I can't imagine how you can expect the machine to last multiple years.
