Dehumidifier in Winter

Confused about whether you should use a dehumidifier during winter months? Some people will tell you that you shouldn’t while others will tell you that you should. So, who’s right and who’s wrong? Find out more below.

Checklist for dehumidifier use in Winter

In order to decide whether you should use a dehumidifier in winter or not, you need to take two variables into account: room temperature and indoor relative humidity. 

1. Temperature check

If the temperature in your room is too low, don’t t run your dehumidifier. At certain temperatures, the coils will freeze and it will begin running on auto-defrost mode. At very low temperatures the dehumidifier will stop working. What’s a low temperature? In the case of TOSOT dehumidifiers too low is 40°F or lower. If you need to dehumidify your space (most probably your basement), make sure that you turn on the heater to temperatures higher than 40°F. For best performance try temperatures around 60°F and higher.
Indications:
    • 40°F or lower: Don't use your dehumidifier. 
    • Higher than 40°F: You can use your TOSOT dehumidifier
2. Humidity levels check

Condensation on windows

Please remember that safe indoor relative humidity levels are between 30% and 55%. You can check indoor relative humidity with a hygrometer.
Condensation on windows? That's a good indicator that they may be high humidity in your home. If indoor relative humidity in your space is above 55% turn on your dehumidifier to prevent mold and allergens such as dust mites from growing.

During certain times of the year, areas with high humidity in the summer don’t necessarily have high humidity during the winter. Remember that very low humidity isn’t healthy either and can increase chances of viruses spreading around. If your indoor relative humidity levels are below 30% you will need a humidifier instead.

    • Lower than 30%: Don’t use your dehumidifier. Use a humidifier instead.
    • Between 35% and 55%: You can use your dehumidifier. Some recent studies suggest that mold can begin growing at an indoor relative humidity of 45%.
    • Higher than 55%: Use your dehumidifier.


Now, combine both temperature and humidity to decide whether to use your dehumidifier or not. This table makes it more simple:
