Thank you for your advice and ideas, BLR and PDM! I like the idea of placing a pot of water on the floor furnace. We use propane.

Right, no kids, none planned. LOL. But I do seem to remember now those vaporizers from my childhood. Do they still sell those? I will keep a look out for a vaporizer and/humidifier in the thrift stores.

I think we need to have a few plants in Dan's office - any advice on which plants might put more humidity into the air?

At least I do not mind the dry air. For me this is normal air. smile
