What size dehumidifier do I need?
Dehumidifiers are rated by how many pints of water they can remove from the air during a 24-hour period. To make sure you choose the right size of dehumidifier, consider two important things: how humid is the area you plan to dehumidify and how large is it?
First, see which of these descriptions best suits the area you want to dehumidify.
Moderately damp: Air sometimes feels damp and area has light, musty odor.
Very damp: Air always feels damp and has a musty odor.
Wet: Area feels and smells wet. Walls or floors sweat.
Extremely wet: Floors and walls are wet.
Then use the chart below to determine what size of dehumidifier would work best for you.
