What Humidity Level Should Your Home Be?

We invest a great deal of time considering properly heating and cooling our homes, especially with winter coming right around the corner.

Managing the humidity inside of your house can be just as crucial to living comfortably as managing the temperature.

You do not want to be within your comfy house throughout the dog days of summertime with every fan pointed at you.

If you think you could be suffering from low or high humidity in your home, keep reading for tips to help recognized the signs and what to do about it.

Before we can determine the ideal humidity for your home, let’s ask the question: what exactly is humidity?

You might have a rough idea that humidity is the amount of water in the air, and you’d technically be right! It’s a little bit more complicated than simply that. To understand what humidity really is we need to speak about the distinction between relative humidity and absolute humidity.

Absolute Humidity
Absolute humidity is the mass (mass = how much) of water in the air, divided by the mass of air that remains in an offered space. Outright humidity is a formula that looks at the actual amount of mass that moisture has in the air around you. Absolute humidity is expressed as grams of moisture per cubic meter of air (g/m ³).

Relative Humidity
The relative humidity is the humidity reading that you are probably more acquainted with. For the functions of learning the perfect house humidity for yourself, this is likewise the measurement we are going to use. While absolute humidity measures the quantity of water vapor in the air, relative humidity measures the current level of wetness in the air out of how moist the air could be. So when you see your humidity reading at 40%, it merely implies that the air around you is 40% as moist as it could be.

Humidity and Feeling Comfy
Do you know why people naturally feel so uncomfortable in really humid climates? Your skin uses the air around it to get rid of moisture in your body. So when the humidity level is near 100%, the air can not take in the moisture on your body, particularly sweat. Sweat is your body’s natural air conditioning system. When you sweat, it is your body’s attempt to preserve its own ideal temperature level (98.6 ). When you can’t get rid of that additional moisture and cool yourself off, the sweat stays on your skin leaving you feeling gross, sticky, and unpleasant.

Discovering the Best Humidity Level for the Air in your house

Now that we’ve talked about comfort levels, you can most likely guess what we’ll state next. The ideal humidity level for your house is going to be relative to you and your family. It will depend primarily on the time of year, what sort of clothes you’re wearing, and where your household is naturally comfy. Research reveals that the ideal relative humidity for your home is between 40% -60%. However, to dissuade the development and spread of mold, levels need to be kept listed below 50%. Again, change this to match your convenience levels. This relative humidity in your house must also scale with the outside outright humidity.

As you probably understand, outright humidity levels change in addition to the temperature level and seasons. In the summertime, the air contains more wetness, and in the winter season, it contains much less moisture.

Here’s a Quick Reference:

  • Outdoor temperature level at -20 ˚F or lower, and indoor humidity levels shouldn’t exceed 15%.
  • With an outdoor temperature between -20 ˚F and -10 ˚F, indoor humidity levels shouldn’t surpass 20%.
  • The outdoor temperature level in between -10 ˚F and 0 ˚F, and indoor humidity levels should not exceed 25%.
  • For an outside temperature level between 0 ˚F and 10 ˚F, indoor humidity levels should not surpass 30%.
