Mildew has a milder, musty smell that some compare to damp socks, but mold smells stronger and more pungent. The reason mold has a more powerful odor is that as it grows, it produces microbial volatile organic compounds (MVOCs).
Mold has a strong, pungent odor that's enough to make you gag. Mildew has more of a musty smell that can make you wrinkle your nose, but it doesn't invade the senses as much. If the smell is reminiscent of wet, forgotten laundry or a damp basement, then you're likely smelling mildew rather than mold.
A moldy or musty smell is frequently associated with the growth of mold or mildew. These smells are due to microbial volatile organic compounds (mVOCs) being released into the air. The mVOCs are produced by mold and as it grows, they can produce strong smells alerting you of mold or mildew growth.
The smell of mold is usually quite foul and unpleasant, and it grows stronger over time as the mold starts to spread and sporulate. “Musty” and “stale” are the most accurate descriptors of what mold smells like. The musty odor is a result of the hodgepodge of mVOCs produced by the mold and released into the air.
Mold is often described as smelling musty. Others have described mold as having an earthy or meaty odor, resembling the smell of wet socks or rotten wood. For many homeowners, the smell is unpleasant and pungent. As mold grows, it can emit gasses known as microbial volatile organic compounds, or MVOC's.
Odor absorbers like baking soda, charcoal briquettes, and even cat litter can abate mold smell and prevent new smells from taking over your home. Fill containers with the odor absorber of your choice, and place them in the rooms where mold is most likely to accrue. Be sure to change these out monthly.
Does the Smell of Mildew Go Away? Mildew, moldy, and musty odors are some of the toughest odors to get rid of once they've set. If left alone, the smells might fade over time, but likely won't completely go away on their own. To get rid of the smells, you've got to also get rid of the fungal growth that's causing it.
A moldy odor suggests that mold is growing in the building and should be investigated. The health effects of inhaling mVOCs are largely unknown, although exposure to mVOCs has been linked to symptoms such as headaches, nasal irritation, dizziness, fatigue, and nausea.
The best way to find mold is to look for signs of mold growth, water staining, warping, or to follow your nose to the source of the odor. It may be necessary to look behind and underneath surfaces, such as carpets, wallpaper, cabinets, and walls.
There are hundreds of different MVOCs formed by mold and mildew and many of them may pose health risks. Though more research is needed, some common symptoms of exposure to microbial volatile organic compounds may include: Headaches. Dizziness.
If your home has a stale, musty scent, there could be a handful of explanations, including a plumbing leak, high humidity, poor airflow, dirty HVAC equipment, or soiled carpet.
You want to look for signs of moisture around pipes, P-traps and drains in rooms or areas with musty smells. Washing machine drain issues: Another common reason your house smells musty but no mold growth is in sight is a problem with your washing machine drain.
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. Some people, such as those with allergies to molds or with asthma, may have more intense reactions.
Exposure to a large number of mold spores may cause allergic symptoms such as watery eyes, runny nose, sneezing, itching, coughing, wheezing, difficulty breathing, headache, and fatigue.
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.
Mildew and mold smells indicate a much larger problem -- mold removal can cost thousands of dollars, plus whatever's letting moisture in will need to be fixed. If you notice a strong smell but are interested in the house, hire an inspector who will pay special attention to unmasking the foul odor.
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.
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.
Mold requires moisture to grow but can remain inactive for a while until it is exposed to moisture or high levels of humidity. Without constant moisture, mold will become inactive but they never die unless you get rid of them completely.
Mildew can produce smells and spores that may spread into the air. Mildew spreads best when these spores find moisture and an organic material to grow on. This could be any sort of leather product, carpet, paper, clothing or furniture.
Wash the musty clothes in your washing machine on an extended cycle with warm or hot water, depending on the color and type of fabric. Use your normal laundry detergent, but don't overdo it. Adding too much detergent may contribute to excess residue on fabrics, trapping in odors. Avoid using fabric softeners.
You might notice a musty smell, but not be able to see any mold growing. In this case, you should look for areas that might be exposed to water. Mold needs moisture to grow. If you're smelling mold in a usually dry area, you might have water damage or a leaking pipe.
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.
Use an air purifier
Air purifiers are a cost-effective and effortless way to remove moisture, allergens, and mouldy smells from the air in your home. If you have a persistent issue with damp odours, try using an air purifier to eliminate the problem.
