A whole-home dehumidifier is built to improve your indoor air quality, so if you notice a sulfuric smell, you've definitely got a problem. Foul smells could be due to mold and mildew growth inside your dehumidifier's basin.
A musty smell from your dehumidifier often suggests that moisture has built up within the device, fostering mold growth, even if it appears to function correctly. Here are steps to tackle this problem:
When the dehumidifer is running it is removing the moisture from the zeolite crystals using heat casuing the smell of the zeolite to be released into the air. This smell is non toxic. It affects all desiccant dehumidifers. This smell will go away eventually.
A bad smell in your room can be caused by various factors, including: Poor Ventilation: Stale air can accumulate odors. Food Remnants: Leftover food or trash can produce unpleasant smells. Mold or Mildew: Moisture can lead to mold growth, which has a musty odor. Dirty Laundry: Unwashed clothes can create a strong odor.
Moisture in the air is a breeding ground for mildew and mold spores, even if they aren't immediately visible. During hot and humid seasons, or in naturally damp areas like basements and bathrooms, humidity levels can soar, leading to that distinctive musty odor.
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.
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.
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.
Consider investing in a dehumidifier and/or air purifier–particularly if the musty smells just keep coming back. Maintain–or start–a regular cleaning schedule. Cleaning regularly will ensure that dust, mold, and mildew don't build up and prevent musty smells from taking hold.
Mold and Mildew
By addressing both mold spores and humidity, air purifiers not only reduce the unpleasant musty smells but also prevent further mold growth.
The filter is dirty (bad smell)
A dirty filter can produce a bad smell. If this is the case, please clean or replace the filter as recommended for your specific dehumidifier.
Musty Smell = Mold
Keep in mind that you're providing moisture to the air using this water to enhance your indoor air quality. If the water has developed a layer of mold, you can be putting mold spores into your home which can cause serious issues for people with allergies or respiratory issues.
Cons of Dehumidifiers
Dehumidifiers collect water meaning they need to be regularly emptied. They also need to be regularly cleaned otherwise black mould can start to grow on the machine , which can induce a wide range of health problems including allergic reactions, lung problems and irritation.
Understanding the Musty Odor Issue
And those organisms release various chemicals and gases as they metabolize organic materials, resulting in a 'musty' odor. So, air purifiers can definitely help, but a better, more effective way to remove that smell is to also remove the excess moisture - with a portable dehumidifier.
Hot and Humid Air Causes Odors to Linger
Heat is often accompanied by humidity, which can be an aggravating factor when it comes to odor. Humidity describes the condition of vaporized water being trapped in the air. This humid air is heavy, so it also has the effect of trapping odors.
Since the dehumidifier is actively pulling the moisture out of the air and into the attached basin, it is a breeding ground for mildew, mineral build up, and mold. Keeping the device clean will keep these issues out of the air and away from your family.
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.
To check your bedrooms for mould, look for visible signs on the walls, in corners, and behind furniture. Also try checking your dirty laundry, looking for leaks around the ceiling, pipes, and radiators, and for damp patches on your soft furnishings.
Ventilate the room
If you sleep with the windows and doors closed, this then gets trapped in the room with you, resulting in a stale odor. To remedy this, Tina Priestly, a home refresh expert, suggests opening up the door to sleep or opening your window every morning to improve ventilation.
Be on the lookout for potential leaks at all times. As well as mould, a musty smell in the bedroom can also be caused by unclean bedding and the build-up of sweat, dust and skin particles. As we sleep, we release carbon dioxide which can become trapped in the room, producing a strong musty smell in the morning.
Black mold has an infamous, recognizable odor. Detecting this scent could be crucial in identifying a mold problem before it causes too much damage. Experts describe black mold as smelling musty—comparing it to rotting wood or leaves or wet, sweaty socks.
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.
Put bowls of baking soda or activated charcoal in the afflicted area because these materials are known to absorb and neutralize scents over time. Leave them in place for several days or weeks, replacing them as needed.
Open windows and doors, or run your ventilation system if you have one. Some areas of the home may also need spot ventilation. Adding a bathroom or kitchen fan near the moisture or pollution source helps to solve common problems. It's all about diluting that stale air.
An air purifier and specific filters effectively eliminate harmful gases and unwanted odors from your indoor environment. A standard particle filter is not designed to remove gases and odors. For gas and odor removal, the air purifier should be equipped with a filter that includes activated carbon.
