I have an issue I am trying to solve with my Furnace mounted evaporative humidifier... I have gone through 3 separate pads just this winter... they are falling apart and eventually end up filling my furnace filter. It’s the clay coating falling off the aluminum mesh. I am using General Air evap pads, name brand and the correct ones specific for my unit.. I can’t figure out if I am just getting bad pads, or if something is wrong... my evap water supply is softened, and originally it was cold and the first two failed with cold water, but I recently switched to hot to see if that made a difference, which it did not. Water is making its way through to drain, but not excessively. My thermostat shows it’s keeping the humidity at about 32% and my setting is 36%... I installed a new valve last year. any ideas as to what’s going on? The only thing I can think of that has changed is my ecobee thermostat is now sending the on off signal to humidifier; instead of the furnace which used a single humidity sensor in the return duct. I made that change about 9 months ago.
