Common Indoor Air Quality Challenges in the Kansas City Metro Area
Throughout the Kansas City metro area, numerous environmental and seasonal factors can impact IAQ, including:
Seasonal Allergens
Spring brings high levels of tree pollen, while summer and fall are heavy with grass and ragweed pollen. These allergens easily make their way indoors, especially if your building lacks proper filtration or ventilation.
High Humidity
In summer, excess indoor moisture can create a breeding ground for mold, mildew, and dust mites. In winter, low humidity levels can dry out nasal passages and skin, aggravating asthma symptoms and leading to respiratory/skin issues.
Tightly Sealed Homes
Many newer homes in areas like Overland Park, Olathe, Lenexa, and surrounding suburbs are constructed with energy efficiency in mind. While this reduces heating and cooling costs, it also limits natural ventilation. Without fresh air circulation, pollutants like dust, pet dander, cooking fumes, and volatile organic compounds (VOCs) from paint, furniture, and cleaning products become trapped indoors.
Airborne Contaminants from Urban Living
In more urban parts of the metro, such as downtown Kansas City, Brookside, and Westport, residents may experience elevated exposure to outdoor pollutants such as vehicle emissions and industrial byproducts. These pollutants can enter buildings through ventilation systems, windows, or doors.
Poorly Maintained HVAC Systems
Without routine maintenance, your HVAC can circulate dirty air and harbor hidden mold, bacteria, and dust. Dirty filters, clogged ducts, and worn-out components are common culprits that reduce airflow and air quality.
