This is a replacement filter for the Transcend Travel CPAP Machines. Because it is made from foam, it is easy to clean. The cleaning process is fairly simple. The filter should be cleaned on a weekly basis with warm water and dish-washing soap, then it should be air dried.
The filter should be replaced every six months, an LED light on the CPAP device will signal if it needs to be replaced.
After replacing the filter, the user must press and hold the power button until the light turns off.
