The connection tubing should be washed weekly in warm soapy water and rinsed thoroughly in clear water. Then hang the tubing over a towel rack/shower to drain and dry completely. Your tubing will be replaced every year or more frequently if it becomes damaged. If you use a humidifier you may need to clean your tubing more frequently.

Filter changing

There are usually two filters that will need to be changed. The white ultra filter needs to be changed every month or when it is dirty. The grey pollen filter should be washed in warm soapy water once a week and dried between a towel. Always allow the filter to dry properly before re-installing into your ventilator machine.
