Difference Between Mold And Mildew

What is Mold?

Mold is a fungus that grows from microscopic spores floating in the air. Mold growth reveals itself in the form of irregular patches of green, black, brown, orange, pink, purple, or other colors. It often appears fuzzy and is typically accompanied by a musty smell. While Mildew grows on top of flat surfaces, mold penetrates the surface and grows into a porous material, eventually breaking it down and causing lasting damage.

Mold can grow on just about any organic surface where moisture and oxygen are present, including wood, carpets, paper, furniture, plants, and insulation. Because it grows best in damp environments, mold is commonly found in bathrooms, basements, kitchens, and crawl spaces. It also often grows near leaks in roofs and windows or behind appliances where water has collected.

Common types of mold found indoors:

Aspergillus—This is an allergenic mold with more than 185 species that’s often found on walls where it forms thick layers.
Penicillium—This allergenic mold has a velvety texture and is bluish-green in color. Areas with water damage, mattresses, and wallpaper are its most popular host sites.
Stachybotrys—Otherwise known as toxic black mold, this variety is slimy in texture, black or dark green, and found in damp areas left too humid for weeks or months at a time.
Aureobasidium—This type appears pink, brown, or black, darkens as it ages, and is found on wooden surfaces.
Cladosporium—Commonly found in carpets, this allergenic mold is olive green and suede-like.

What You Need To Know About Mold

Mold is a type of fungus, green or black in appearance and with a fuzzy or slimy texture.
Mold grows underneath the surface of anything that has got wet or moist, ideally can be seen on perished food items.
Mold appears as irregularly shaped spots that can have different colors – blue, green, etc.
Mold may be used in food production, example, penicillium is utilized for cheese making.
Mold can be prevented by keeping all areas in home dry and free of moisture, not keeping perishable foods for too long.
The smell of mold is that of a pungent rotting wood or paper, accompanied with release of harmful toxins.
Mold penetrates the surface and grows into a porous material, eventually breaking it down and causing lasting damage.
Mold can cause minor to severe health issues, depending on the species, length of exposure, and whether or not the individual has any pre-existing conditions, such as allergies or asthma.

What is Mildew?

Mildew is a common gray and white fungus that’s often powdery in appearance. As a microscopic fungus it travels through the air in the form of tiny spores. When these spores land in damp or humid environments, mildew begins to colonize and grow.

Mildew is generally classified as either powdery or downy. Powdery mildew is white or gray in color. Over time, it turns yellow and eventually dark brown or black. As the name suggests, it has a fine, powdery texture. Downy mildew initially shows up in the form of yellow splotches. As it ages, these splotches turn a darkish brown.

Since mildew grows on surfaces, it’s often easier to spot in its early stages than mold. In homes, mildew will grow on damp materials like paper, leather and fabrics in addition to walls and other wet surfaces. Mildew is most commonly found in bathrooms, kitchens and basements. It usually gives off a musty smell that indicates an infestation is nearby. Mildew is a surface fungus that can be easily removed with a store-bought-cleaner or bleach and a scrubbing brush.

Common types of mildew found indoors:

Basidiospores—This variety is associated with dry rotted wood. These mildew spores eventually become mushrooms and can cause severe allergic reactions.
Aureobasidium—Generally described as “bathroom mold,” this mildew is found in showers and bathtubs.
Botrytis—Often found in humid greenhouses, this type of mildew is found on indoor plants and can trigger asthma symptoms.
Rhizopus—Dangerous to those with existing health conditions or nutritional deficiencies, this toxic mildew grows on garbage, house dirt, and food.

What You Need To Know About Mildew

Mildew is a specific type of mold usually in white, gray or yellow color and with a fluffy or powdery texture.
Mildew thrives on moist or damp surfaces such as bathrooms, walls, ceilings, damp surfaces, paper, fabrics.
Mildew will usually appear growing in a flat pattern.
Mildew may not be used for any food related purpose.
For preventing mildew, one can use mildew removers, using mildew-resistant seeds, and fungicides.
Mildew has a stale, or damp smell.
Mildew grows on top of flat surfaces. It doesn’t penetrate surfaces and grow into the materials it lands on (though it can still cause cosmetic damage).
Mildew can cause health problems with prolonged exposure. While the fungi themselves are not toxic, certain species produce mycotoxins, which can cause mild to severe symptoms in humans.
