In the last century, buildings have become more “sealed.” While this has helped reduce the amount of energy used in cooling and heating, it has also made it easier for gases and other toxic substances to build up in our homes and workplaces.

Today, indoor air in the U.S. is two to five times more polluted than the air outdoors. With the average American spending about 90% of their time indoors, chances are you’re inhaling polluted air most of the time— whether it’s at work or home. Fortunately, there are several things you can do to improve your indoor air quality and get rid of the stale air.

But first, let’s address the root of the problem:

What Makes a Room Stuffy?

When the air indoors gets stuffy, it’s often due to high humidity or a high concentration of certain chemicals and gases. This can be caused by:


Whether its tobacco, wood, or coal, burning anything indoors without proper ventilation displaces oxygen, and increases concentrations of carbon dioxide and other particles in your indoor air.

That’s why homes with gas stoves have carbon dioxide concentrations of 30ppm or higher. In comparison, homes without gas stoves have 5ppm or less.


Cleaning supplies, insecticides, paint, and other similar day-to-day products can introduce harmful chemicals—including volatile organic compounds—into your indoor air. Additionally, some building materials can also pollute the air in your home. For example, hazardous asbestos fibers and chemical off-gassing from new pressed wood can affect your respiratory system when inhaled.

Poor Ventilation

Poor ventilation lets harmful gases and other substances accumulate in your home. It also increases humidity, which can make your indoor air stuffy by allowing mold and mildew growth.

How to Fix a Stuffy Room

With a myriad of health issues linked to poor indoor air quality, fixing your stuffy room should be a top priority. You can do this by:

1. Improving Ventilation

Open your doors and windows, and switch on your ceiling fan. If you have a central cooling system, turn it on and let it stay on more often. Not only will this remove the stale air, but it’ll also allow fresh air from outside into your home.

2. Changing Your HVAC Filter

A clogged HVAC filter compromises the effectiveness and efficiency of your ventilation system. If dirty, mold, or bacterial will start to grow in it and will eventually blow contaminated air into your home. To prevent this, change your HVAC filter regularly and keep it clean.

3. Cleaning and Drying Musty Items

If you have any dirty or moist items in your home, clean them, and let them dry in the sun for several hours. Not only will this get rid of the musty smell, but it also kills the mold or bacteria causing it.
