Replacing the Filter: The Transcend Air Inlet Filter should be replaced every 6 months or sooner if it appears worn or damaged. Transcend CPAP machines include an LED light indicator to signal when filters need be replaced under normal usage conditions. After a new filter is inserted reset the LED light indicator by pressing and holding the Transcend power button until the LED light stops flashing.

Cleaning the Filter: Transcend filters are reusable; they should be cleaned on a regular basis with a mild liquid soap and warm water and allowed to air dry.
