Dehumidifier Buying Guide
How Does a Dehumidifier Work?
A dehumidifier sucks in moist air, filters it, and then sends it through a condenser that is kept at a lower temperature. The resulting condensation then goes to a reservoir. As the appliance continues to operate, the moisture in the air is gradually removed until the desired humidity is reached.
The Best Dehumidifier for Your Needs
Before you shop for a dehumidifier, you should get a hygrometer so you can measure the relative humidity in the room. According to Health Canada, the safe range for relative humidity is between 30 and 50%.
Then calculate the volume of space to be dehumidified, so you know what extraction capacity you need for your appliance. For example, you need an extraction capacity of at least 6 liters per day for 500 sq. ft., and a minimum capacity of 12 liters for 2000 sq. ft.
Features to Consider
Are you looking for a particular model? In addition to the extraction capacity, consider the following features and options:
- What type of regulator, or humidistat, does it have (manual operation or LCD)
- Is there an automatic defrosting device (most late models have one)
- Is there a programming function (on/off switch you can program to operate according to your schedule)'
- Does it have the ENERGY STAR symbol (a guarantee of high energy efficiency)
- What is the ease of handling (size, weight, on casters, etc.)
- How loud is it (with rare exceptions, the more powerful the appliance is, the noisier it is)
What Is the Effectiveness Factor (EF)?
Before you get out your wallet, take note of the efficiency factor (EF) on the dehumidifier you are looking to buy. This number shows how many liters of water the appliance can extract from the air at a temperature of 27° C and 60% relative humidity for each kilowatt hour (kWh) of electricity. Of course, the higher the number, the more efficient the device. While the minimum allowable EF rating is 1.2, note that 1.8 is that much better. When you shop for a dehumidifier, actively seek out this information... Save your money!
