Hi everyone, 

I found that my AM10 is having a hard time humidifying the room. Put it into my son’s room (size about 80 sqft) with a full tank of water, set the humidity target to 60, fan speed to 1. Over the whole night, the humidity level hardly went above 38% (from 33%), and in the morning the water tank is still half full. 

Is there a setting I should change? Does the fan speed matter? Don’t want to turn it on too much because it will be loud for sleep.

If it matters, I live in Ontario Canada with the overnight temperature about 0 C / 32 F. Also recently replaced the faulty piezo.

Thanks a lot in advance!
