This listing supplies a 2-pack of the ResMed S9 AirSense cpap filter, the standard disposable air filter designed for use with ResMed S9 and AirSense 10 series CPAP and APAP machines. The filters sit at the air intake of the device and capture airborne particles before they enter the flow generator, protecting the internal components and supporting consistent air quality throughout therapy.
These are in-house checks on new stock only. Contents are verified against the pack. Commissioning and clinical verification remain with the operating organisation. Damaged or incomplete packs are not dispatched.
The air filter is a consumable component. Its function is to prevent dust, lint and airborne debris from entering the flow generator during nightly therapy. A blocked or degraded filter restricts intake airflow, which can affect device performance and, over time, place additional load on the motor.
ResMed classifies this as a standard filter. It is not an ultra-fine or hypoallergenic filter. Check your device documentation or ask your prescribing clinician if a specific filter grade has been recommended for your therapy setup.
These filters are compatible with ResMed S9 series and AirSense 10 series machines. Check the filter part number against your device manual before ordering if you are unsure.
| Action | Detail | Interval |

Standard ResMed air filters are single-use and are not designed to be washed or reused. Follow the replacement schedule in your device manual. Where manufacturer instructions differ from the guidance above, the manufacturer instructions take precedence.
