Some sources of common odors in properties may be the result of cigarette smoke, cooking odors, cleaning supplies or even pets. They can also result from inadequate ventilation, unsanitary conditions, water damage, mold, bacteria and even vapor intrusion.

Additional sources of mystery odors may be coming from sewer gases or off-gassing from building materials and household products. Formaldehyde and volatile organic compounds (VOCs) are common culprits.

These odors may be signs of potential short or long term health concerns for building occupants as some off-gassing chemicals are known carcinogens.

In commercial and institutional settings, off-gassing from manufacturing chemicals and manufacturing processes is also a possibility.

Mystery odors could also be infiltrating a structure from an outside source. These odors enter the building through air intakes, windows and doors. They may include vehicle exhaust, landfill odors, air pollution from nearby factories or any number of sources.
