Here we have the replacement filter for the Transcend 365 miniCPAP. When replacing the inlet filter to the Transcend 365, simply press the tab on the filter frame of the device and pull it away from the CPAP. The current filter will present itself and then replace the old filter with the new filter and snap it back into it;s original place. Viola! Maintaining overall good health and making sure to breath clean is important which is why it is the best practice to replace the filter every six months. In doing so, this will provide you with optimal performance when using the Transcend 365 miniCPAP machine.
