Basements can often be a problem room in regards to mold growth because they have little exposure to heat and sunlight from outside.

They often have the issue of trapping moisture inside because of this.

As most people know, a dehumidifier can regulate humidity in rooms such as the basement and other shut-off areas of the house.

However, in the winter months, having your dehumidifier running depends on some very important factors.

2 Factors to Consider When Choosing Whether or Not You Should Run a Dehumidifier in the Winter

Here are some things to keep an eye out for as you debate whether you need a dehumidifier in your room over the winter.

1. Where You Live

Be careful if you live in cold weather climates. Since the purpose of a dehumidifier is to attract moisture, the coils can possibly freeze if the weather gets too cold.

However, in rooms that are above 60 degrees Fahrenheit, such as a heated basement and the like, a dehumidifier would work just fine. Just be careful when the temperatures start dropping and keep an eye on your device while in use.

2. Your Relative Humidity

You should pay attention to your humidity levels as you debate about whether to use a dehumidifier in the winter months.

If your relative humidity levels stay high even in the later months of the year, it might be a good idea to run your device.

If your humidity levels remain above 50 percent quite often, your room will benefit from running a basement dehumidifier and keeping the mold from developing.

Don’t know your current humidity levels or your current dehumidifier doesn’t have a meter? You can get a handy hygrometer that will help you monitor the humidity levels and help you calibrate your settings correctly.

3 Things to Keep in Mind If You Choose to Run a Dehumidifier in the Winter

Here are some major things to consider if you do choose to run a dehumidifier in the winter months.

1. Monitor Your Device Regularly

You must keep an eye on your device whenever you decide to run it. If the temperature or humidity levels drop below the ideal level, you will want to turn it off.

If you can set an automatic humidity threshold, the most logical amount is 30 percent humidity. This will keep the room dry but not overly so.

2. Monitor the Room Temperature

If you happen to notice that the room is cold, but you are still developing high humidity, a heater can be run for a few hours each day. This will help regulate the temperature in the room, making it a little easier to control the relative humidity.

3. Keep an Eye Out for Mold

If you still notice signs of mold growth even with taking the above measures, make sure to kill it immediately using natural fungicides like white vinegar, hydrogen peroxide, or rubbing alcohol.

Then you have to dry the room completely, often accompanied by uses of your dehumidifier, to make sure the mold has not spread.
