Dehumidifier Settings

When there’s a lot of humidity in the air, it affects the indoor air quality of your home and causes an excess of moisture—and even mold growth in some cases. But with a dehumidifier you can manage the humidity and make the air feel cooler, allowing you to feel comfortable in your home despite the high levels of humidity outside. However, many people wonder what dehumidifier setting is best for their space—and we can help you determine this.

What Should My Dehumidifier Be Set At?

Overall, you’ll want to keep the relative humidity (RH) level in your home between 30 and 60 percent, with the most optimal RH between 40 and 50 percent. It’s also important to remember that if the dehumidifier setting is above 75 percent, it can cause mold and mildew to grow. But the most appropriate dehumidifier setting depends on a number of factors relating to the dehumidifier itself and the environment where it’s installed. Here are some things to consider:

  • what type of dehumidifier you have
  • what size it is
  • its location
  • the humidity levels where it’s installed
  • your comfort preference

It’s important to note that the level of humidity can vary from room to room, even in the same house. The basement, for instance, might accumulate a lot more moisture than the bedroom on the second story. Typically, a dehumidifier will contain a sensor that detects the level of humidity in your environment and runs based on this sensor. Therefore, it will automatically run continuously if your basement or crawlspace has very high humidity levels. If your dehumidifier does not have such a sensor, you may have to test out different dehumidifier settings in order to find the best one for your comfort preferences.

And in order to ensure that the dehumidifier functions properly, and the dehumidifier settings are working as intended, it’s essential to maintain your dehumidifier by emptying and cleaning the pan when necessary. An indicator light or automatic shut-off will typically alert you when the pan needs to be cleaned.
