We do get a lot of questions asking are mildew and mold the same? No, they are not the same despite you often see them grow side by side together. Nonetheless, both mold and mildew do share many similarities as they are types of fungi that are commonly found in the home. They thrive on wet and warm conditions with humidity levels above 50%. Finally, mold and mildew will grow rapidly and easily spread through airborne.
What Is Mold?
Mold (mould) is a fungus that grows in the form of multicellular filaments structures called hyphae. It has a fuzzy (hairy) appearance with darker green or black color. A typical mold can germinate in 12 hours with good condition. There are 4 stages of growth cycle: Hyphal growth, spore formation, spore dispersal, and spore germination. As mold grows, it can emit microbial volatile organic compounds (MVOCs) gases which are the chemical compounds linked to the musty smell. There are 13 common types of mold in the home. From Alternaria, Aspergillus, Cladosporium, Penicillium, Stachybotrys, Acremonium, Aureobasidium, Chaetomium, Fusarium, Mucor, Trichoderma, Ulocladium, and Serpula Lacrymans.
What Is Mildew?
Mildew is a fungus that is closely identical to mold but appears in lighter shades of color. You can tell them apart with its unique powdery appearance in black, white, blue, green, grey or yellow highlight. The 2 common types of mildew are Powdery mildew and Downy mildew.
What Is the Difference between Mold and Mildew?
There are subtle differences between mold VS mildew from the appearance (texture, color), stages of growth, and health risks. First off, mold is fuzzy, slimy multiple nuclei (Multinucleate) that grow in black or green patches with a hint of brown, white and yellow colors. Mildew is a multicellular, fuzzy, powdery look in black, white, grey, blue, green, or yellow patches. Mold can penetrate beneath porous materials while mildew has a flat growth and will remain on the surface of the material. Mold will literally grow on anything both indoor and outdoor. Common places include food (bread, meat, cheese), wall, ceiling, bathroom, garage, kitchen, basement, crawl space or boat. Mildew will also grow in places mold resides, but it will likely grow on objects that are exposed to wetness such as fabric, paper, and leather goods. Both mold and mildew have a distinct musty smell but thankfully mildew has a milder, less invasive odor.

What Are The Effects Of Mildew VS Mold?
You can get sick from mildew or mold. In general, mildew is less harmful than mold other than impacting plants, crops, and minor allergic reactions. You will experience allergic reactions like runny nose, cough, red eyes, sore throat, dry skin, or headache. Once mildew has been removed from the surface, all your health symptoms will be gone with the wind. Mold is much more dangerous as it can cause irreversible damage to our health, food, and building structure. Other than the same eyes, ears, nose, and throat symptoms as mildew, mold is not particularly kind to an asthmatic person. It can aggravate asthma conditions with children and elderly the higher risk group. If you are unfortunate to encounter the toxigenic black mold, you are at risk of the following diseases: hallucinations, respiratory tract damage, heart inflammation, rheumatoid arthritis, infertility, impotence, lung cancer, or liver failure. Removing mold can be tricky as they may have penetrated been within the wall, ceiling or floor. Symptoms may recur from time to time until the room is completely mold-free. Seek medical advice or treatment immediately if one is experiencing mildew or mold poisoning.
How Hard Is It To Remove Mildew VS Mold
You can easily remove mildew with some soap, vinegar, baking soda, essential oil and give it a good scrub. On the other hand, mold requires additional efforts and stronger mold remover tools to eradicate the fungus for good. If there are too many deposits hidden inside porous materials like dry wall, you may need to seek mold removal expert.
