I am overjoyed with the new Mini water supply system. I have owned a MK2 for quite a while and loved it, but did not like the need for continuous cleaning actions. I am a former engineer and pilot and always thought that it could be done easier and simpler.
The advent of the Mini allows me to use a 1 Gallon Distilled Water Jug straight from the supermarket to use it as the reservoir and discard when emptied. Much less cleaning required there. I now clean the tubing and pump unit with a White Vinegar/Water mixture every 1-2 weeks and flush with a clean water rinse, using a tube brush when needed.
I found that having a second water chamber to rotate out each cleaning cycle allows me to clean the chambers each time and get them ready for the next cleaning cycle. So much faster and easier than before.
I wished that they had used Quick Connect/Disconnects on the Mini to the in/out tube runs, but it is not that bad. The Mini is louder than the MK2, since the pump is no longer immersed in the water reservoir, but it is not bad. After working with support, I found that the water jug had to be lower than the CPAP to avoid siphoning of water from the jug to the CPAP water chamber.
Love the Mini and use it as my primary and travel machine. Great job Sebastian and the whole team.
