Thanks for the insight guys. I just remembered that I padded the backside of the grobo where the intake fans are and the humidifier I am using Is leaving a white dust, from calcium most likely. I didn’t even think to look at that. Thanks All!

I have the same issue when I run humidifiers because I use tap water with a lot of calcium and/or lime. From what I have read it is harmless mostly. Just keep an eye out for buildup on the fan blades.

There’s a product out there that is called a humidifier conditioner. It seems to help remove the calcium/lime in the water.
