Volatile organic compounds (VOCs) are organic chemicals that can evaporate into the air under normal indoor conditions. They can be released by paints, coatings, cleaning products, air fresheners, adhesives, building materials, furnishings, fuels, and many other products. Some VOCs have recognizable odors, while others may not be readily detected by smell. Odor alone cannot identify a VOC or determine its concentration or health risk.

EPA notes that indoor VOC concentrations can be affected by products and materials used or stored indoors, ventilation, temperature, and other environmental conditions

Why Every Odor Has a Source: The Science Behind Finding the Real Problem

Every odor has a source because odors are created by molecules released from physical materials or biological processes. Smoke, mold, bacteria, pet contamination, moisture, sewage, food, and chemical compounds all release microscopic molecules into the air. These molecules travel to your nose, where they're detected by your olfactory system. Eliminating an odor permanently requires identifying and removing its source—not simply masking the smell with fragrances.

Have you ever smelled fresh bread and suddenly thought about your grandmother's kitchen? Or caught the scent of a campfire and remembered a family vacation? That's because your sense of smell is directly connected to the parts of your brain that control memory and emotion. This system is called the olfactory system, and it is one of the fastest and most powerful senses your body has. Understanding how it works can help explain why certain odors make us feel happy, relaxed, uncomfortable, or even anxious.
