Room temp is always kept warm at 76-77 F so I don't use a heated humidifier unit. I took a look at my room temperature monitor and humidity level was at 22%. Bingo! The weather had been a little colder for the past week and the heater was on for longer durations causing the room to be more dry.
I normally use a room humidifier but decided not to on this night to give the room a break from all of the moisture and not grow any fungus. Needless to say, I turned it back on at full blast. I also opened the window for a handful of minutes to get some fresh air in.
I decided to use the ResMed humidifier unit in passover mode with no climateline or heat. I also bumped the max pressure of the S9 down which I should have not done. 5-13 to 5-9. A few events happened afterwards. I also gave my nose a squirt of saline spray and went back to bed. Everything was good again.
I also had the lowest AHI ever even with these issues. AHI of .62, 4 events in total. The Zeo score was not so great.

I will keep the cpap humidifier attached and use in passover mode. Hope this might help some newbies who might run into the same situation.
This is my room humidifier setup taken at an earlier time. But I don't recommend this particular unit as it is hard to clean and fill with water.
