The optimal range for annual indoor relative humidity (RH) is between 35 and 55 percent. Unlike portable humidifiers that are only effective in the rooms they are located in, or other whole-house humidifiers that only deliver moisture when your heating equipment is running, Honeywell's TrueSTEAM Humidification System is truly different.
