I have searched the forums and not read anything about a solution to offset the dry air caused by forced air heating of homes. I was have been having trouble keeping the humidity up in my humidor ever since turning on the heat this season. Adding more distilled water every couple of days seemed to be the only solution. Then it dawned on me to take the hydrometer out of the humidor and check the humidity outside of the humidor. The RH was reading around 25% after leaving it out for 24 hours. I was wondering if anyone has thought of installing a furnace mounted whole-house humidifier to bring the humidity of the house to a comfortable 40-50%, thus helping the humidor not loose as much moisture?
