One of the more infamous types of dangerous fungus is black mold, otherwise known as Stachybotrys chartarum, which is among the many forms of mold that can contribute to respiratory problems or aggravate asthma symptoms.

Temperature gradients are also a contributing factor to mold growth. In the same way condensation may occur on a cold soda can on a warm day, condensation can occur inside a warm attic during cold days, encouraging mold and mildew to grow rapidly.

Consider purchasing a whole-house dehumidifier if you continue to have trouble achieving balanced humidity in your home. If one room in particular, such as the bathroom or basem*nt, has been flooded or contains excess moisture, consider purchasing a portable dehumidifier to quickly remove moisture from the environment.

When cooking or taking a shower, use exhaust fans to immediately remove condensation as it’s produced before it has the opportunity to cause mold and mildew problems. Other causes of high humidity levels may be plumbing leaks or a damaged roof that’s allowing water to seep into various parts of your home.
