How Long Do Mold Spores Stay in the Air?

Mold is a type of fungi that grows in humid areas and on various surfaces. The idea environment for mold to grow is moisture, and is easily spotted in insulation materials, carpet, fabrics, wallpaper, and paint among others. 

There are various types of mold, and the most common one is the black mold which appears as a greenish-grey coloring and mostly forms rings around wet surfaces. 

How Long Does Mold Spore Stay Airborne? 

Mold spores can stay airborne for a couple of days, depending on their weight. Since they are very light, they continue to linger in the air until they get attached to other particles, become heavy then land on other surfaces. 

Mold spores can easily get attached to other surfaces, this means that if airborne, they will easily get attached to other objects and be transported around.

Mold spores can stay dormant in the air for a very long time, this has been proved by a discovery of mold spores in ancient Egyptian tombs. 

Therefore, mold spores never die, but only go into an inactive state. They can go back to the active state when they are exposed to moisture. 

Can Mold Spread Through the Air? 

The answer to this question is in the affirmative. Mold particles are very tiny and can easily travel through air. The mold spores fly in the air and travel all over, attaching themselves to different objects.

Since mold spore are very light, they can stay in the air for a number of days. They can only land on surfaces when they become heavy or when they come into contact with those other surfaces.
