Although mildew/mold might add to the musty odor in your home, other variables can cause this odor to develop in your air space. Pollutants and microorganisms in your home’s environment may also add to the musty odors in the air.

One of the possible health effects of a musty smell is that it irritates and makes you sneeze. Sneezing and headaches are common symptoms of mold allergy. Other frequent symptoms include a runny nose, itchy throat, congestion, and dry skin. As a result of spores entering the nostrils, mold allergies develop. They can also induce asthma when they reach your lungs. These symptoms may appear later in life and intensify over time. If a homeowner has these symptoms more indoors than outside, they likely have a mold allergy, which is present in the home.
