Update:

Just got my Z2 Auto CPAP. It looks great. Good as new. However, I have a few questions and a problem issue. I'll email the supplier about it too of course, but I was wondering if any of you experienced the same or if it's normal.

1. The instruction guide says to change the filter every month. But I remember you guys said you can just wash the filter and reuse it long term. Am I right or did I misunderstand or misremember what you folks said about it?

Where do I get replacement filters? What's the easiest way?

Also I can't open the top to even see the filter. It seems dammed shut. I don't want to force it and risk breaking it.

2. What's the ramp pressure thing? Do I need to mess with it? Do most people just ignore it?

3. The problem issue is that the apap setting worked at first. It was set at apap 2 (the default setting) and when I put on the mask the pressure readings were varying between 13 and 14 range up and down. But when I manually set the pressure range from 7 to 20, as the forum members here suggested, and as the YouTube tutorial videos instructed, all of a sudden the CPAP pressure became fixed. It stayed at 7 throughout the whole night and wouldn't budge. And yes I made sure it was on apap 2 and not cpap mode. When I tried to change it back to the original settings between 5 and 7 it then remained stuck at 5. It seems to always remain stuck at the lowest setting. It seems the apap worked in the beginning but once I changed the range of high and low values, the auto mode no longer works, not even if I put it back to the original range.

How did that happen? Is this a software bug? I certainly hope it's not a hardware problem. Any of you experienced this before?

4. Should I try to reset the firmware by downloading it from the manufacturer's site?

Thanks.

You may have messed up a setting. If you set the ramp incorrectly, it can cause the problem you are having.
This is a link to the tutorial.

You also may want to search for a copy of the clinician’s manual.

I would strongly suggest not messing with firmware at this point.

Thanks. I saw that video created by the manufacturer, Breas. I also saw some tutorials by this Australian CPAP supplier who made videos about how to set up the Z2 too, since he also says it's his favorite.

I followed their instructions to the T. I did not set anything for the ramp so it should be deactivated. It's currently off at 0 minutes. So I don't know what happened. Perhaps when you initially turn it on, it starts at 13 to blow off the dust from the machine or hose at first, before going back to normal?

Let me ask you: When you use auto cpap setting, does it start at the lowest setting and then if the sensors sense obstruction in your breathing, then it gradually increases the pressure? For the last few nights I noticed it's been doing that. I set it at 5 to 20, and it starts at 5, then later while I'm asleep it goes up to 8 or 9. When I wake up and check it, it's usually at around 8. So I presume it increases during the night when it senses obstruction in your throat right? If so, maybe my machine is working normally as it should after all? And the initial 13 pressure was just a fluke or an attempt to clear the airways first when first out of the box?
