You can feel the bad odor coming from the air vents of your house or office. In some cases, the smell is persistent. In other cases, it comes and goes and its intensity changes over time. Even though the symptoms may vary, they are a sign of a serious problem which must be identified and dealt with quickly.
If there is a musty smell in the rooms and it does not go away no matter how often you open the windows or use an air spray, then you are most certainly dealing with mold or mildew inside the air vents. Both of these are types of fungus. They can have a variety of colors from white, pink, yellow and green to black. They can be damaging to surfaces and pose serious health hazards.
