One thing you can try is cupping your hands around electrical outlets on exterior walls and sniffing in them. You might be able to pin down the general location of the odor. You can also sniff near the corners of the window trim to try to locate the odor source.
Check for Moisture: Look for any signs of water damage or leaks in bathrooms, kitchens, or around windows. Damp areas can lead to musty odors. Inspect Air Vents and Filters: Dirty air filters or mold in ductwork can contribute to musty smells.
Why does my apartment smell musty even though there is no visible mold? Musty odors can be caused by hidden sources of moisture such as leaking pipes, condensation or poorly ventilated areas.
The top causes of musty odors in bathrooms are from fungal growth. Mold and mildew are types of fungus found in damp spaces, like bathrooms. The constant presence of moisture in bathrooms creates an environment where fungus can thrive.
General dampness, repeated condensation, and high humidity can sometimes bring on a musty smell. Since dampness can also facilitate mold growth it's likely that mold is beginning to form once you start noticing a musty smell.
A musty smell is almost always an indicator of unmanaged moisture. This moisture could either be liquid water or vapor. Unmanaged moisture often presents as mold or mildew. If unmanaged moisture reaches the point of smelling musty, it has likely reached the stage of mold or mildew.
Baking soda and vinegar are often regarded as some of the best natural cleaning ingredients given their inherent deodorizing properties. When using these ingredients to remove the smell of must, simply place a bowl of either baking soda or vinegar in the affected room overnight to absorb the musty odors.
Mold can grow anywhere there is adequate moisture or a water problem. 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.
Serious liver disease can make breath smell musty or like garlic and rotten eggs. Compounds that are transported through the blood can also be released through your sweat glands. That can make your armpits and skin smell bad. It's normal for stress to cause smelly compounds to be released through your sweat.
Mold, when it flourishes indoors, exudes an odor. Experts liken the smell of mold to a forest lush with earthy vegetation, soil and decaying wood. Others connect the scent of dirt lying beneath decayed leaves with the smell of mold. More homely descriptions suggest mold smells like wet, dirty socks.
Or it could be an odor that isn't actually present (known as phantosmia). Your symptoms suggest you have periods of phantosmia: your brain registers an odor when none is present in the environment. But at other times, it could be parosmia, meaning you are more sensitive to a smell that doesn't bother other people.
Problem: Musty or moldy smells typically indicate mold or mildew growth. Who to Call for Solution: Seek a professional mold remediation service. They are experts in identifying, removing, and preventing mold in homes.
Check under and in the refrigerator and small appliances that use water, like coffee makers and tea kettles. Be sure to also check the trashcan, as mildew could be growing under the disposable trash bag liner.

Summary. You might be dealing with plumbing leaks, water damage in hidden spots, or washing machine drain issues if your house smells musty but no mold is visibly present. The first thing to do is identify the source of the smell before attempting to eliminate the unwanted odor.
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.
Odor sensors have been extensively used to detect gas leakage and in fields such as healthcare, mobility, and spatial environment control, in which the detection of low-concentration biogas and odor is crucial [3].
Damp, mould and mildew are the most common causes of a musty or stale smell in houses, creating this smell by emitting gases known as microbial volatile organic compounds (MVOCs) as they grow.
If you weren't able to identify where the moldy smell is coming from, the mold might be growing in hidden areas like ducts, air vents, HVAC, attics, or walls. Check humid and damp areas in your home where mold might be hiding. If these methods fail, consult a professional to inspect your home for mold contamination.
Most often, a mold problem will be readily identified by a musty smell that becomes obvious in damp environments. Mold also likes to play hide and seek, so if you suspect there is a problem, then check under carpets, behind drywall, inside ductwork, in between bathroom tiles and in other moisture-prone areas.
With prolonged condensation dampness, mould spores can thrive and permeate into walls, carpets, furniture and other soft furnishings. In some cases, the actual mould growth and source of the musty smell may be hidden from view perhaps behind a wardrobe or in a cupboard.
