Hi, not sure how the Z1 and Transcend compare. The Transcend filter seems to be integrated with the mask (see https://www.youtube.com/watch?v=Oi0ECrYNtS8) whereas the Z1 is "universal."

Thanks for the response. I wanted to try the H6B since the filter attaches directly to the mask whereas the Z1 filter is in-line so it is positioned after the mask vent.

Is it possible to use the Transcend H6B Humidification System with a non-Transend CPAP? That is will the tubing fit another CPAP or if not is there an adapter?
Thanks
