Read on to know how you can identify these unique fungi.

Mold vs Mildew

What is mold?

This fungus spreads through microscopic spores floating in the air. Mold is essential to the ecosystem, as it helps in the decomposition of dead matter. This process allows for nutrients that the dead materials possessed to be released back in the soil, for living organisms to use. Although these fungi might be good for the outside, inside your home, it can cause aesthetic and, more importantly, structural damage. Additionally, it’s a well-documented health hazard.

What is mildew?

Mildew is best defined as an early-stage mold. Even though one comes after the other, the two couldn’t be more different in their behavior. In your home, mold can destroy the structural elements of your home, while with mildew, you only have to worry about the cosmetic damage. Nonetheless, mildew is just as destructive to plant life in nature, as is mold.

Even though mildew can pose a health risk to you, it’s not anywhere near as harmful as mold. It’s cheaper, less dangerous, and easier to deal with mildew before it turns to mold. Mildew usually grows on moist and flat surfaces, making it easy to distinguish between the two at first sight.

How does mold affect your health?

You’ve probably heard some people lay claim to falling ill because of mold. Sure, these fungi that spread through microbial spores are a definite health hazard, but even those with different colors pose a health risk all the same. If you have allergies or suffer from a respiratory condition like asthma, you might have had an unforgettable brush with mold since it aggravates the symptoms. Other symptoms for those who are more susceptible could be dry, scaly skin, itchy eyes, nose, and throat, runny or stuffy nose, coughing, wheezing, chest tightness, and shortness of breath. The severity of the symptoms varies depending on age and overall health. In fact, most people without allergies only get to recognize mold when they see it.

If experiencing such symptoms, inspect problem areas, and deal with the issue promptly.

Mold surges on, with long filaments poking out, which look fuzzy to a human eye. It can appear in different colors, ranging from yellow, green, brown, blue, gray, white, and black.

What does mold smell like?

Mold typically has a soft smell, but when it does, it can often be described as “musty.” At some stage in the molds growth stages, it can emit microbial volatile organic compounds (MVOCs). These microbes float around in some stages of the mold’s growth, so technically, you are not smelling the fungi but its chemical compounds.

What does mildew smell like?

Just like mold, mildew also emits MVOCs, and similarly, the smell is musty. Therefore, distinguishing between the two, in terms of how they smell like can be challenging. You will need to see visually and determine which is which.

Is mildew mold?

Mildew and mold are not plants, but fungi. It’s no surprise then that they have a lot in common.
