When to Use a Dehumidifier: In Winter or Summer?

When Should you use a Dehumidifier

Dehumidifiers are great for relieving dry air and various problems that bother us. But when should you use one – in the winter or summer?

To make things even more complicated, it’s not as simple as getting one and using it.

To answer your question, “when to use a dehumidifier winter or summer?”, as it turns out, using a dehumidifier depends on relative humidity levels. If it’s high, you can use a dehumidifier during the year.

You’ll need a dehumidifier to get the perfect moisture level throughout your home. It all depends on your region, the condition of your home, and your lifestyle habits.

When should I use a dehumidifier?

You can use a dehumidifier in both winter and summer. High humidity in the summer is as bad for your health as low humidity in the winter. A dehumidifier is helpful in winter, too, although it’s due to a lack of humidity in the air. When it’s cold outside and hot inside, it can make the air dry.

That means a dehumidifier can and should work in winter and summer. I will tell you to keep windows open during the summer while a dehumidifier is running.

Opening windows will cause a dehumidifier to have trouble maintaining the humidity level since it will change inside the room.

Dry air can cause a dry throat and irritations if you breathe through your mouth. How often have you experienced a dry throat during your sleep or even during the day?

Low humidity during winter can cause more significant health issues, such as spreading viruses more quickly and causing dry skin or nosebleeds.

Pay attention to the settings on your dehumidifier. Make sure they’re adjusted to the variations in seasonal indoor temperatures.

Summer and winter are both great for using your dehumidifier. But for different reasons.

Using a Dehumidifier in Summer

Summer can often be exceptionally hot. It’s humid, sticky, and impossible to feel comfortable day and night.

Opening a window may seem like a good option until bugs fly in and more hot air is fanned around your home.

Opting for a dehumidifier in the summer months will help you relax at home in the daytime and get good sleep.

If you’re concerned about your skin drying out while using a dehumidifier in summer, you can turn it on for a couple of hours a day.

Using a Dehumidifier in Winter

Using a dehumidifier in winter is a standard option for people who have noticed mold growing. Mold thrives off the cooler climate and moisture in the air. Running a dehumidifier to tackle some of the water will stunt mold growth.

Use a dehumidifier in winter with caution if your home or area is freezing. The weather is too cold for the dehumidifier to run correctly. The interior workings of the unit may freeze up. If this happens, the unit may not work anymore.

Suppose you want to use your dehumidifier in winter but are concerned about the temperature of your house. You can consider running a dehumidifier with a heater.

You don’t need to run the heater all the time. That would be expensive and may result in your house being too hot. Run the heater for a few hours a day.

If you do this, you’ll see a reduction in mold growth, have a warmer house and have peace of mind when using your dehumidifier.


A dehumidifier can be used during any season, mainly when used with other methods to tackle mold and moisture in your home.
