Why Does Indoor Air Feel Stuffy?

A stuffy home is not always caused by one obvious problem. Sometimes it is a mix of dust, pet odors, cooking smells, humidity, cleaning products, smoke, pollen, and air that simply is not moving enough.

EPA notes that indoor air pollutants can come from both outdoor and indoor sources, including cooking, cleaning, secondhand smoke, building materials, consumer products, and home furnishings. These pollutants may include particles, gases, VOCs, formaldehyde, mold, and pollen.
