Most homeowners have had to deal with dampness in the basement or even in the laundry room. This problem is caused by the excess moisture in these rooms. This problem can be experienced even in homes with air conditioning thus a dehumidifier is needed.

Do I need a humidifier?

Any homeowner requires a dehumidifier if the relative humidity levels in the house are over 30% in the winter months and over 50% in the summer months.

How I measure the humidity to know the humidity levels are high?

You can easily measure the humidity of your basement with a hygrometer (can be purchased from most retail stores).

If you have no access to a hygrometer, then you can look out for the following signs:

  • If the basement is damp and you can smell mildew and mold, this is a clear sign of high humidity.
  • In extreme humidity levels in the basement, you will be able to spot condensed water on the walls or puddles of water on the basement floor.

How does a dehumidifier work?

There are a number of designs for basements dehumidifiers from different brands in the market today. However, in many dehumidifiers, moist air in the basement is directed over coolant filled coils by a fan. The moisture condenses over the coils and drips into a collection apart. The dry air is then expelled back into the basement.

  2. Buy a basement dehumidifier that can be connected to a hose to drain the water.
  • Buy a basement dehumidifier that is able to operate optimally even at low temperatures.
  • Is the basement dehumidifier energy star rated? – We highly recommend you invest in an energy star certified dehumidifier. This will keep your energy consumption for drying the basement low and affordable.
  • Choose a basement dehumidifier with an auto humidistat – This allows the dehumidifier to automatically turn on and off depending on the level of humidity in the basement. This saves energy and keeps the basement dry.
