Mold vs Mildew: The Main Differences between Mold and Mildew

Mold and mildew are both types of fungi that are commonly found in the home. They thrive in moist environments, spread easily, and live on various surfaces which makes them very difficult to get rid of. If left unattended, however, the harmful microorganisms can quickly affect large areas of your property and may even result in health problems and structural damage. While the two types of fungi share many common features, they pose different risks and respond to different treatment.

So, in order to come up with an efficient cleaning strategy and ensure the safety of your living environment, you need to understand the difference between mold and mildew.

What Is the Difference between Mold and Mildew?

Mildew can be described as a specific type of mold. Mold is a fungus that contains multiple identical nuclei and grows in the form of black or green patches which penetrate beneath the surface of the affected material. Mildew, on the other hand, has flat growth that remains on the surface where it can be easily removed. While mold usually grows on food or inside permanent structures, such as walls and crawl spaces, mildew is to be found on damp surfaces, paper, fabrics, and various organic materials in your home.

Common Mildew Types

Primarily, mildew is a plant disease that causes great damage to crops and plants. It is classified as powdery and downy:

  • Powdery mildew mainly affects flowering plants and first appears as white or gray patterned splotches that gradually become yellowish brown or black as the fungus grows;

  • Downy mildew is commonly found in agricultural products, such as grapes and potatoes. Its appearance varies depending on the type of surface it grows on, but usually downy mildew starts as yellow spots that eventually turn brown.

Common Mold Types

Although the number of mold species that can live indoors exceeds 10,000 according to the latest CDC estimates, most household molds belong to one of the following five types:

  • Alternaria grows on walls, in showers, around windows, under sinks and in various other damp places. It is often found in buildings that have suffered some kind of water damage. Alternaria mold can appear black, grey, or dark brown and has a wooly or down-like texture. Prolonged exposure to this kind of fungi can cause allergic reactions and asthma attacks;
