Question about Aprilaire 550 Humidifier
Unit is 10 years old and never have had this problem. Dry lime scale also showing up in furnace filter which has never happened before.
If your water is suddenly evaporating into limescale, your local water company may have switched to a different water source, or your water softener device is out of salt. The limescale can be easily cleaned with vinegar and a sponge, but this will keep occuring unless you use water that doesn't contain disolved calcium. Try getting an RO water filter and use that water.
