Humidity Levels


Manage Humidity Levels Through the Seasons

When the weather heats up, high humidity levels are often close behind. Seasonal humidity can affect indoor home comfort. Managing the humidity in your home during all seasons can make the time you spend there much more enjoyable.

People often describe summer to be heavy, sticky and muggy. While winter air can feel dry, crisp and bitter. These descriptions are related to the feel of the air due to the differing amounts of moisture present at different times of the year.

What is Humidity?

The amount of water vapor in the air around you. The optimum humidity in your home depends on your personal preferences, clothing, and level of physical activity.

How Does Humidity Change With the Seasons?

Summer Air: Warm, summer air “holds” more moisture, so the humidity is higher.

Winter Air: Cold, winter air contains less water, so the humidity is lower.

Extreme Humidity Creates Problems

Too much or too little moisture in the air can cause a variety of health threats and illnesses.

Excess Humidity Levels Sources

The optimum relative humidity range is 45% – 55%. At higher and lower levels of humidity, health threats and illnesses can increase. These include: bacteria, viruses, fungi, mites, respiratory infections, allergic rhinitis and asthma, chemical interactions, and ozone production.
