Reusable pollen filters are used to trap fine particles that can infiltrate your unit, and ultimately harm your respiratory system. This filter is included with the purchase of a CPAP unit. Manufacturers recommend changing them after 6 months of use.
The heated tube is made with a heated wire to avoid condensation inside the tube while ensuring a good humidity level. It is recommended to change it once a year. Also compatible with System One 60 series devices.
