I have an American Standard AHUMD200ABM00BA humidifier and these Aprilaire 10 filters are an exact replacement. Good quality and can actually last more than one season. It depends on how long you need/want to run your humidifier. Be sure to check for limescale and mineral deposits in the filter. A clogged filter can cause water leaks as the water flow is restricted. It is best to change the filter right at the beginning of the cold season and you should not have any problems. Good quality and works well.
