What Should I Set My Humidity Control At

You’ve decided to install a humidifier in your home. You’re wondering what the ideal level of relative humidity should be for it to work properly. The right humidity level can make a huge difference in how comfortable you feel in your home and how much water is absorbed by the air.

40% Relative Humidity (RH)

  • 40% Relative Humidity (RH) is the ideal humidity level for most homes. If you have a problem with mold, mildew and other fungi and spores, this is the best way to maintain a healthy environment for your plants.
  • 40% RH is also an easy target for newbies who aren’t sure what their humidity levels should be set at yet. Set these at around 40% then move them up or down as needed based on how you feel about your plant’s health—or if there’s something else in your life that needs attention from the watering can!

45% Relative Humidity (RH)

The recommended humidity level for a home is 45% relative humidity (RH). This means that the air in your home contains about 45% moisture, with all of that moisture being water vapor. The ideal level for most homes is 50-60%. If you live in an area where it gets very dry, then you might want to consider setting your humidistat lower than what we recommend.

50% Relative Humidity (RH)

The 50% Relative Humidity (RH) setting is a good balance between comfort and energy efficiency. If you live in a warm climate, this is the best option for most people. It’s also recommended for reducing static electricity and preventing mold and mildew in humid areas.

55% Relative Humidity (RH)

  • 55% Relative Humidity (RH)
  • This is a good level for many people, and it’s a good balance for keeping your skin and hair healthy. It’s also good for your plants and houseplants. The downside is that it can make you feel more tired than usual, so try to avoid this if you’re trying to stay awake at work or school.

60% – 65% Relative Humidity (RH)

  • 60% – 65% Relative Humidity (RH)

The ideal level for most homes is about 60% – 65%. This is a safe level of humidity that will help to keep your skin and hair healthy, as well as promote healthy growth overall.

70% Relative Humidity (RH)

The most important thing to remember is that the recommended level of relative humidity (RH) for your home is 70%.

The 70% RH guideline comes from a number of sources, including the Environmental Protection Agency (EPA) and the American Society for Testing and Materials (ASTM). It’s also used by many building codes in North America.

Here are some reasons why you should set your thermostat at this level:

  • Increased levels of mold growth—if there are too few air exchange points or ventilation systems in your home, then it could lead to increased moisture levels within walls and ceilings over time.
  • Dust mites—you may have heard about how dust mites can cause allergic reactions in people who suffer from asthma or other allergic conditions; they’re also thought to be responsible for causing asthma attacks in children who haven’t yet reached adulthood.


Now that you’ve learned about humidity, it’s time to get back to the task at hand: finding out what level of humidity control is best for your home.

First off, let’s talk about what humidity actually is. Humidity is a measure of how much water vapor exists in an air sample; it can be measured using a hygrometer (not just any old one will do). The amount of moisture in our atmosphere varies from season to season but generally averages between 15% and 25%. In other words, if you were to take away all of the moisture from each room in your house and put them into one big pile, we would call this pile “the air.”

Now that we understand how much moisture there is in our environment—and how important it is—let’s think about where this comes from: plants! Plants release water when they absorb sunlight through leaves or stems; then when those leaves fall after being touched by wind currents they leave behind seeds which eventually sprout new plants like tomatoes or peppers depending on whether they’re planted indoors or out on sunny windowsills during summer months where temperatures reach up 100 degrees Fahrenheit (38 C).


If you’re looking to maintain a healthy environment in your home, it’s important that you take good care of the humidity levels. The first step is setting up your humidifier correctly and then monitoring the settings regularly. This will ensure that your home stays comfortable all throughout the year!
