Improving Wintertime Indoor Air Quality

Indoor air quality refers to the characteristics of the air that circulates through your home. These characteristics include temperature, humidity, and the percentage of airborne particles, particularly those that cause allergies, asthma, and other respiratory illnesses. During the winter, homeowners are more likely to keep their homes tightly shut against the cold weather—while this can improve your home’s heating efficiency, it can also influence indoor air quality in many ways. Learning how to improve the air quality inside your home this winter will mean enjoying greater comfort and health throughout the heating season.


Humidity plays an important role in both the comfort and energy efficiency of your home. The ideal humidity for your health and your home should fall in the range of 40-50%. However, during the winter, naturally dry air can become even drier during the heating process, causing health problems that affect the eyes, skin, nose, mouth, and throat. Extremely dry air can even affect the finishes and materials inside your home, and cause your heating efficiency to drop because dry air holds less heat than humid air. Adding a steam humidifier to your heating system is an excellent way to retain control over the humidity of your indoor air, replacing lost moisture for greater comfort inside your home. Furthermore, adding moisture to your indoor air will make it feel warmer, reducing the amount of energy your heater requires to achieve the comfort you want and lowering your utility bills throughout the winter season.

Airborne Particles

Air naturally contains particles that include dust, pollen, and microorganisms such as mold, viruses, and bacteria. If you have a pet, hair and dander can also be found in the air inside your home. Over time, these particles can contribute to poor health and increased asthma and allergy episodes, as well as buildup that affects your furnace and your ducts, lowering your home’s heating efficiency. Although your furnace filter is designed to screen out many of these particles, theres is a limit to the efficacy of the average replaceable air filter. During the winter, airborne particles can become even more easily trapped in your home when it is sealed against the outside air, allowing them to continue circulating and causing negative effects. Adding an air purifier or active whole-home air filter can eliminate many of these particles from your air altogether, improving the health and breathability of your indoor air by removing allergens, microorganisms, and even odors and dust. You’ll also enjoy more effective heating by eliminating the particles that contribute to buildup for better airflow through your home’s HVAC system.
