Things You'll Need:
-
Step 1
Measure the square footage of your house. Many manufacturers make charts to help match the right dehumidifier with the right square footage.
-
Step 2
Measure the amount of water, in pints, that is removed from the room in 24 hours. This can be done by purchasing a humidity gauge.
-
Step 3
Buy a dehumidifier that covers more square footage than what the room measures. If you measure 900 square feet, for example, purchase a dehumidifier that covers 1000 square footage.
-
Step 4
Determine if you need a dehumidifier for the whole house or for one room. You'll save money if it's just for one room.
-
Step 5
Research the cost and warranties offered. It is always safe to have a warranty in case the product does not perform as advertised.
