Increasing the air flow through your humidifier with a 6" duct fan will increase the evaporation rate. Larger shorter duct and high speed on funace fan also increases evaporation rate. At 70F, 30%RH, your inside dew point is 37^F. Whats your outside dew point or location? What is the temp of the water going into the humidifier? Check with fingers. Neutral indicates 98^F. 35-40%RH is about as high as you should go to avoid condensation on windows and other cold surfaces.
