In a whole-house bypass-humidifier setup, the humidified air still has to go through the furnace filter.

Doesn't that filter out some of the water vapor? Especially with the expensive filters that filter a lot of things out.

No. water vapor is a gas - it passes right through, same as oxygen and nitrogen (i.e., air)
