Mildew and mold are both fungi, but mildew is not as invasive or troublesome as other types of mold. Typically found in wet areas, mildew looks grayish-white and may turn brown. It's flat and powdery and it's an easier fungus to clean because it lives only on the surface of a material (such as bathroom tile).
Many confuse mold and mildew, which is not surprising — they have more than a few things in common: Both are types of fungi that no homeowner likes to see in his or her home. Both are keen on forming in moist, warm areas.
Mildew is typically a light color, most often gray, but white and yellow are also possible. It will appear fuzzy, fluffy, or powdery. On the other hand, mold tends to be dark green or black. It can look fuzzy, but you may also see it appear slimy, like mildew.
While mold and mildew are both fungi that need water, oxygen, and food in order to live and survive, they differ in a number of ways. Mold tends to have a higher profile and can even become fuzzy, while mildew is usually flat.
Although toxic molds draw a lot of attention due to their numerous health effects, many other molds are non-toxic. Some examples of such molds include cladosporium, nigrospora, and ulocladium. Most individuals get into contact with these molds daily with little to no health effects.
Pay attention to the color and consistency: We already talked about black mold above, though it's more accurate to say that Stachybotrys chartarum has a greenish-black hue. Toxic mold can also have a grayish, soot-like texture, or a slimy, wet surface. In some cases, you may even notice furry orange or brown spots.
Mold generally looks slimy or fuzzy, tends to have a raised texture, and can come in a rainbow of colors, including deep green and black. Mildew is powdery, looks white or gray, always appears flat, and grows on surfaces.
Use undiluted white vinegar on hard surfaces in kitchens and baths. A bleach solution also works to kill mold. Mix one cup of bleach in a gallon of water, apply to the surface and don't rinse. Mix a 50/50 solution of ammonia and water.
These symptoms usually first appear 2 to 9 hours after exposure and last for 1 to 3 days. Other affected persons have progressive shortness of breath and cough, as well as weight loss. Work-relatedness may only become apparent over long holidays if symptoms resolve and then recur on return to work.
Active mold in the early stages has hair-like filaments in webs, which develop a more bushy appearance as the bloom matures. Inactive mold is dry and powdery, and the surface layer can generally be readily brushed off the surface. Inactive mold can easily become active given the right environmental conditions.
A musty smell. Persistent physical symptoms (sneezing, runny noses, red eyes and skin rashes) that seem to lessen when the sufferer is not at home. If you see mold on the walls or floors of your home, and it's less than a 3-foot by 3-foot patch, clean it using bleach and water, and let it dry completely.
If the mold is on a hard surface, which includes paint on a wall, use a cloth or sponge dampened with water, or water mixed with a little detergent, to wipe it off. Rinse out the cloth or sponge and wipe again.
Ghosting is the slow buildup of air-borne dust, dirt, and soot particles on walls or ceilings. Also known as “ghost stains,” “bridging,” or “thermal tracking,” ghosting creates strange patterns along exterior walls and black spots on ceilings.
Physical Characteristics: Alternaria mold is dark (grey, brown, black) with a velvety texture. Health Symptoms: Development and/or agitation of Asthma.
When searching for black mold, look for circular-shaped spots that are black, dark green or dark brown. Some black mold can also take on shades of orange or have flecks of white within it. Most of the time, black mold has a slightly furry appearance.
Without a doubt, mold is worse than mildew. According to American Home Shield, “the difference between mold and mildew is that unlike mildew, certain types of toxic molds can result in serious health problems for you and your family.” Black mold, in particular, is dangerous for humans.
Do air purifiers help with mold? Air purifiers help capture mold spores from the air, preventing them from reproducing and spreading throughout your home. While air purifiers won't help treat active mold that's already present on surfaces, they are a great way to control the spread of airborne mold particles.
Nasal corticosteroids.
These nasal sprays help prevent and treat the inflammation caused by an upper respiratory mold allergy. For many people, they're the most effective allergy medications, and they're often the first medication prescribed.
In some cases, mold in your home can make you sick, especially if you have allergies or asthma. Whether or not you're allergic to molds, mold exposure can irritate your eyes, skin, nose, throat, and lungs.
Cleaning vinegar, which contains 6% acetic acid, is the best type for killing mold. White vinegar containing 5% acidity will also work just fine. If you don't already have some at home, white vinegar can be inexpensively purchased at most grocery stores.
Mold stays “dormant” in the air or on surfaces even when there's no excess moisture to help it grow. If the humidity in a room increases, mold will start growing in patches on walls, clothes, and more. So, to answer your question, dehumidifiers do NOT kill mold, but they do prevent it by reducing humidity.
However, it is quite risky living in a home with visible mold since you are exposed to mold spores that can become airborne when blown around by the gush of wind from your windows or HVAC systems. If mold is left unattended, it can spread to other areas of your home causing serious health problems.
Exposure to damp and moldy environments may cause a variety of health effects, or none at all. Some people are sensitive to molds. For these people, exposure to molds can lead to symptoms such as stuffy nose, wheezing, and red or itchy eyes, or skin.
Mildew is considered an early stage of mold, though it is not as common as mold. It thrives in moist environments and often looks like a powdery substance.
