Short Answer to What Should My Humidifier Be Set At?

The ideal range of humidity for your home will almost always fall between 30 and 50%, any higher will over-saturate the air, and any less will most likely result in a dry, scratchy environment.

What is Relative Humidity?

The relative humidity of a space is ​​the measure of the water vapor content of air represented in a percentage. The percentage indicates the feeling of saturation in the air. When a space has high humidity levels, it will feel warmer and vice versa, so although humidity doesn’t affect the temperature of the air, it affects how the air feels to humans.

What Should My Humidifier Be Set At Based On The Weather?

It can be hard to know the ideal setting as the weather outside fluctuates. Next time you aren’t sure how to set your humidifier, refer to the list below.

  • When the outside temperature is 20-40 degrees, indoor humidity should be no more than 40%.
  • When the outside temperature is 10-20 degrees, indoor humidity should be no more than 30%.
  • When the outside temperature is 0-10 degrees, indoor humidity should be 30% or lower.
  • When the outside temperature is -10 or 0 degrees, indoor humidity should be below 25%.
  • And finally, if the outside temperature drops below 10 degrees below freezing, set your humidity to no more than 20%.

Effects of Poor Humidity Levels

If the humidity levels in your home aren’t ideal, it can be incorrect in two different ways. High humidity levels and low humidity levels can make for an uncomfortable atmosphere, so you need to find the perfect balance so you can enjoy the quality of air in your home.

When humidity levels are too high, condensation can form on windows and floors, making everything slightly moist. High humidity is generally uncomfortable for people and pets in your home. Condensation can also create a slipping hazard on tile or concrete floors.

Many don’t consider this, but high humidity levels will affect baked goods, like bread, resulting in soggy or overly soft bread. Any water-sensitive belongings can also be damaged if the humidity levels rise too high.

And worst of all, high humidity levels foster a breeding ground for mold and mildew that can harm your health. An overly humid environment will likely lead to illnesses since bacteria can more easily spread in moist environments.

Low Humidity

If the humidity levels in your home are too low, this can damage your entire house. Dry air forces cracking in drywall and other problems that impact the integrity of your house. In addition to this hazard, dry air is uncomfortable and can make you feel cold in your home.

Like overly humid air, dry air can lead to sickness like dry throat, coughing, wheezing, and trouble breathing. Many of us don’t realize how valuable a moderate humidity level is to our health and comfort.

Bottom Line

It is important to keep your humidity at appropriate levels for the outdoor weather, or it may make your home uncomfortable for you. Many people don’t realize that relative humidity affects much more than just our comfort.

So to keep your family happy, healthy, and comfortable, refer back to this guide when the weather changes and you aren’t sure if your home’s humidity is decent. It is as simple as clicking a button on the appliance a few times.

Don’t neglect to check your humidifier settings as the seasons come and go because if it isn’t set at the proper level it won’t monitor your home air in the way it should.
