Where to buy a dehumidifier

You can buy a dehumidifier at almost any home supply retailer or home improvement store. Appliance stores and department stores also tend to keep them in stock.

Before you purchase, you’ll need to know:

  • what tank size you’re looking for (how much water the dehumidifier collects at a time before you need to empty it)
  • what range of humidity the appliance can control

You may also want to figure out the energy costs associated with the appliance before you purchase it.
