Pianos don't do well in very dry environments. Dry air causes wood parts to shrink, crack, and loosen up. A dry piano action will make clicking noises due to loose parts. A dry soundboard will change the tuning of the piano 1/4 step or more, and will crack. If the pin block dries out, loose tuning pins result. A humidifier inside a piano is designed to prevent this. Concensus on this forum says that they help somewhat, but aren't a cure-all. The best way to solve the dryness problem is to control the ambient humidity in the room. Install a furnace humidifier, or place a humidifier close to the piano (not blowing on it). Do not overheat the room. 68-70 degrees max. Avoid placing the piano next to heat vents or radiators. Use air conditioning in the summer. If you can keep your humidity higher than 30% in the winter, you are doing ok. A discussion on piano humidifiers was had recently in the Piano Forum. You may want to search for it. \:\)

Pianos usually prefer about 40% humidity, but that's impossible to maintain when the outside temp is 20 below zero, without condensation damaging your home. Thats why shoot for 30%. The idea is to avoid levels 20% or less.
