Humidifier didn't use water last night

So i filled it close to the max line on my PR system one LEVEL 3 why did it not use humidification

Possiblliy because it was humid enough in the room that it didn't need to use any.

When I first got my PR System One REMStar 60 Series SE CPAP Machine with heated humidifier I thought there must be something wrong with the humidifier. I would wake up at night and found no signs of warmth at all. My DME simply said that the machine could sense that no humidity was needed. Anyway, a web search brought me to this forum where I finally found some answers.

I learned that the PR System One Heated Humidifiers Version 1.22 or higher have two modes: 1.) Classic and 2.) System One Humidification. By default it is set to use the System One Humidification where it attempts to sense whether or not humidity is needed. I found I preferred it set to Classic mode where the humidifier comes on and just continues to run.

The description below is from cpap.com. Refer to you owner's manual for more information.

Classic Mode
The CPAP user who wants to control the heat setting on the humidifier should select "Classic" mode settings C1,C2, C3, C4 or C5. The "C" in front of the humidification setting indicates "Classic". This allows you to set the level of humidification.

System One Humidification Mode
The CPAP User who wants to allow the technology of the System One Humidification to set the level of humidification delivered based on the humidity present in the room air should select "System One Humidification". The humidification setting will show 1 - 5 but WITHOUT a "C" preceding the number.

Heating Off
If set to zero “0”, the humidifier will act as a Passover Humidifier.

Accessing Humidification Settings:

Humidifier must be attached to the machine
Access the Set Up menu
Scroll down the menu offerings to locate: "System One Humidification"
If set to "On", the technology will set the amount of humidification delivered to the system based on the setting of 1 -5 with 1 being the least and 5 being the most
If set to "Off", the user controls the heat setting based on C1-C5 with C1 being the lowest heat and C5 being the highest heat.

Just outta' curiosity... how did you feel without the humidifier?
