I have a humidifier on the side of my furnace and a supply line that gets run over to the humidifier that is a plastic (pex?) line. Perhaps it has always looked like this, but does it look filled with dirty water? Perhaps it's always looked like this and it has never caught my attention before? Any advice would be appreciated!

Shut thr line off. Unscrew it. Let it run into a clear jug for a couple min. See if there's anything in th jug. If so flush it longer. Check by filing the jug again.

It could be that some "stuff" has settled into this water line and it just needs flushed. If it continues you either have bad water or something is backflowing/ contaminating your water.

The pictures are not visible for me. But I'm guessing they're opaque PEX tube.

It could be that that particular water run doesn't get much flow so whatever is in the line just sets there.

I've attached the pictures. What you are saying definitely sounds possible. This wouldn't have gotten any flow since last winter/spring.

Likely caused just super low flow.. plus its a bit of copper scale which is a coating of oxide inside of your copper pipe that actually protects the water from coming into constant contact with the solder and potentially lead in that solder. You could get it tested, but its probably just nothing to worry about.

Over time, it's not unusual to get some deposits on the inside of the pipes. Shut your main water supply valve off, drain the system, then turn it on...you are likely to flush out some crud through the surge of the water refilling the pipes, but it clears up quickly...when my utility opens up the fire hydrants annually to flush the lines, for the next few hours, the supply to my place is often cloudy, and, they warn people in advance so they don't get freaked out...crud on the insides of the pipes is not unusual, it's just that on the translucent pex tubing, you can see it.
