Introduction

The ResMed S9 VPAP Auto is a medical ventilator, commonly referred to as a VPAP (variable positive airway pressure machine). This guide will direct you to access and replace both the inner and outer filters on the device. The filters help to remove dust and debris from the air as it is cycled through the device. Over time the filters will need to be replaced due to the build-up of debris. Replacing the filters will improve the function of the device. Replacing them will keep the device working longer and more efficiently. For more information on the device, go to the manufacturers home page.
