Mold and mildew The most common cause of a sudden musty smell in a house, especially in winter, is the development of mold and mildew, often caused by humid conditions and condensation. A musty smell, accompanied by dark discoloration on walls, furnishings, ceilings, or carpets can be the first sign of spores.
Some of the best odor eliminators are coffee grounds, tea, vinegar, oats, and baking soda. Leaving a bowl of any of these odor absorbers out in a room that's due for a little freshening up will help clear out the less-than-pleasant smells from the air.
A weird smell in a house can come from numerous sources, including appliances, furniture, carpets, fabrics or issues like mold or mildew. Occasionally, odors may be caused by sewer gas, natural gas leaks or animals that have died between walls, in attics or under decks.
A musty or dusty smell is often a sign of mold or mildew, especially in humid or moisture-prone environments like the basement, laundry room, kitchen, or bathroom. Mold and mildew can create severe respiratory problems and can exacerbate allergies and asthma in sensitive individuals.
If it is outdoors, or if the windows are open, then the smell is stronger near the source. Moving your nose from place to place is a way to determine the gradient of concentration of smelly molecules. Follow the direction of the gradient to locate the source.
It's often described as musty and earthy, and may even smell like rotting vegetables or plants. 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.
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.
Common culprits to watch out for include mold and mildew, dust, dirty laundry, stains and spills, pet accidents and leftover food. Once you determine the source of the smell, dispose of it and clean the area as needed.
“One of the best methods to tell if your home stinks is to leave it. Go away for a day or two, or even a week,” says Bryan Stoddard, handyman and interior designer. “Close all windows and doors, shut the blinds, and seal the place up air-tight.
Baking soda: Just as baking soda works to absorb odors in your refrigerator, a bowl placed in a room will also absorb odors. Lemon water: Water absorbs odors and adding slices of fresh lemon will provide a clean citrus scent.
Air purifiers work by filtering and removing particles that may cause bad smells. However, the EPA states that no air cleaner or filter will be able to eliminate all the particles that can cause foul odors.
How long will a bowl of vinegar absorb odors for? You can leave a bowl of vinegar out in the kitchen for several hours and it will help to get rid of smells.
Add about 25 drops of your favorite essential oil to 2 tablespoons of baking soda and stir to combine. Lemon and lavender are great choices, but eucalyptus is my favorite because of the refreshing scent. Pour the baking soda and essential oil mix into the water and stir. Then funnel the water into your spray bottle.
Exposure to odors could result in health effects ranging from none, to mild discomfort, to more serious symptoms. Some chemicals with strong odors may cause eye, nose, throat or lung irritation. Strong odors may cause some people to feel a burning sensation that leads to coughing, wheezing or other breathing problems.
A bedroom can smell in the morning as a result of body odour, dust, moisture in the room, dirty bedding and a messy room. Poor air circulation at night makes unpleasant odours linger until morning. These smells can be avoided by regularly cleaning the bedroom and making sure to air it out every day.
If the smell is particularly strong, don't stay in the house; instead, treat the situation like an emergency (which it is) and leave the home. Call 911 from a safe distance for emergency services, then let trained professionals handle the issue.
Locate the Source of the Musty Smell
Check for mildew growth in the shower, on the shower curtain, and leaks around sinks, tubs, and toilets. In the kitchen, look for leaks around the sink and dishwasher. Check under and in the refrigerator and small appliances that use water, like coffee makers and tea kettles.
Bottom line: If you can't actually see mold, it's almost never a problem. The musty smell you ask about doesn't necessarily mean there are mold spores present, but can simply indicate you need more ventilation with fresh air.
To get the last of the musty smell out of your house, use a natural odor absorber like activated charcoal or baking soda. These products will absorb the smell, so you'll want to throw them away and replace them every two weeks or so.
If you see grey, black, green, or bluish specks along grout lines, on walls, or other surfaces, it is most likely mold. Keep an eye out for pink, red, or brown streaks, as well. The texture of mold can be powdery, fuzzy, or slimy. Dark water stains on walls, floors, or ceilings usually indicate the presence of mold.
Black mold is a fungus that may cause your immune system to react. Common symptoms include sneezing, coughing, congestion and eye irritation. It rarely causes serious illness or death but may worsen asthma symptoms.
Mold will smell musty and stale. But if the mold has been growing in your home for a long time, the smell will be stronger like how sweaty socks or rotten meat smell.
Deodorize the Room
Unpleasant odors lurk in the carpets, rugs, and upholstery. To remove these musty smells, fill a dish with half an inch of white vinegar and leave it out in the room until the smell dissipates.
Yet a few inexpensive household essentials you probably have on hand already—vinegar, salt, coffee, baking soda, hydrogen peroxide—will neutralize most noxious odors around your home and in your vehicles.
