Old orchids on the windowsill

Growing fitfully, they need repotting. I’m going to have to do it soon as the orchid medium is spent, but they have reflowered a few times. They need clear plastic pots to let light to the roots apparently. My worst habit is not keeping them misted so they are a little dry. I’ve got two more on the kitchen windowsill but I think it will be too cold in there in the winter so I will be moving them into the living room where it’s warmer..
