Is dehumidifier for winter or summer? A dehumidifier can be used in both winter and summer. High humidity in the summer is bad for your health as much as the low humidity in the winter is, in fact.

When it’s cold outside and you have heating inside, it can make the air dry. If you have read the previous parts, I’ve explained how dry air can cause headaches.

Dry air can cause dry throat and irritations. If you are breathing through the mouth. How many times did you experience dry throat during your sleep or even during a day?

Low humidity during the winter can cause even bigger health issues. Such as spreading the viruses more easily, causing dry skin or even nosebleed.

You have to pay attention to the settings on your dehumidifier. Make sure they’re adjusted to the variations in seasonal indoor temperature.

Also, a good dehumidifier for a basement can be very useful if the air quality inside isn’t good enough for living.

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

Using a Dehumidifier In Summer

Do you use a dehumidifier in the summer? Summer can often be exceptionally hot. It’s humid and sticky, and impossible to feel comfortable throughout the day and night.

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

Opting for a dehumidifier in the summer months will help you enjoy relaxing at home in the daytime. And get good sleep throughout the night.

If you’re concerned about your skin drying out because of the use of a dehumidifier. You can switch it on for a couple of hours a day.

Using a Dehumidifier In Winter

Using a dehumidifier in winter is a common option for people who have noticed mold growing. Mold thrives off the cooler climate and moisture in the air. So, running a dehumidifier to try and tackle some of the moisture will stunt mold growth.

If your home or area is extremely cold. Then using a dehumidifier throughout winter with caution in these cases. Weather is too cold for the dehumidifier to run properly. And the interior workings of the unit may freeze up.

If this happens, the unit could become broken for good. Don’t put off using a dehumidifier in winter, though, be careful.

If you want to use your dehumidifier in winter. But are concerned about the temperature of your house a consider running the unit with a heater.

You don’t need to run the heater 24/7 (this would be very 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 it comes to using your dehumidifier.


Final words, a dehumidifier can use in any season. Especially when used alongside other methods to tackle mold and moisture in your home.
