How to Find the Ideal Humidity Level for Your Home (and Why It Matters)
When it comes to the temperature inside your home, you probably have a good idea of how warm or cool you need to be to feel comfortable, and based on your energy costs, what you can afford. But what about the humidity level in your home? Your thermostat may indicate what it is, but ideally what should it be?
Here’s what you need to know about the ideal humidity level in your home and why it’s important.
What is the ideal indoor humidity level?
According to the Environmental Protection Agency (EPA), indoor humidity should be kept below 60%, ideally between 30% and 50%. The reason indoor humidity should be below 60% is because anything higher can encourage mold growth in your home.
Even if the house has not been flooded, humid air can contain enough moisture for mold to develop, which in turn can cause or activate respiratory illnesses in family members. Also, dust mites thrive in high humidity, so this is bad news for anyone with allergies. Pests such as cockroaches are also lovers of high humidity.
Signs that the humidity level in your home is too high or too low
In addition to watching the humidity level displayed on your thermostat, there are other signs that it may be getting too high or too low.

Why Indoor Humidity Matters
