Is there a Humidifier that does not Mold?
Certain humidifiers do not mold because they are made with special technology that prevents mold and bacteria development inside them. Humidifiers that do not mold can be divided into two subtypes.
This division is based on the method used to avoid bacteria and mold from growing inside the humidifier.
Humidifiers that use UV light
Some humidifiers are designed with a special UV light that is beamed inside the components. The UV light destroys the DNA of cells of bacteria, mold, and mildews. Therefore, the UV light’s continued beaming prevents mold, bacteria, and mildew from growing inside such humidifiers.
Humidifiers that have germicide
Germicides are chemicals that interfere with the growth of bacteria, mold, and mildew. Germicides work by killing off the cells that need to multiply rapidly for mold and mildew to grow in damp conditions.
For humidifiers that use germicides, the chemical is applied inside the plastic compartment. It remains active for as long as the humidifier is in use. Thus, such humidifiers remain completely mold-free during their lifetime.
How do I Know if my Humidifier has Mold?
You will know if your humidifier has mold by either experiencing or observing others’ development of a condition called ‘humidifier lung.’
This condition occurs when people breathe air that is contaminated with spores of molds and bacteria. The small particles of the spores get into the body of people through the nasal cavity.
Here are a few noticeable symptoms of the condition. When you either experience or observe them in others, it means that your humidifier has mold.
- Mild to moderate fever
- Dry cough
- Fatigue and difficulty in breathing
- General aches in the body
Alternatively, you will know if your humidifier has molds if you sense a different unpleasant smell in the air. Spores of molds have a distinctively pungent smell even when they are dead.
If there are molds in your humidifier, small particles of molds and spores pass to the air together with the moisture. The particles cause a distinctive smell in the room.
What Happens if you Use a Moldy Humidifier?
Several unpleasant things can happen if you use a humidifier with mold, mildew, and bacteria growing inside.
Here is a brief explanation of how the effects of using a humidifier that has mold unfold and what it means for your health and general comfort.
Foul Odors in the Air
Molds and bacteria usually grow in water that has been stagnant for some time. When they inhabit the internal components of your humidifier, they spread spores across the entire device.
The spores of molds find their way into the air as the humidifier dissipates moisture. The spores have a naturally pungent smell. When they get discharged into the house’s atmosphere with the moisture, you will undoubtedly start to smell the foul odor in the entire house.
The spores of molds can cause a range of unpleasant health conditions. Primarily, when people breathe air that is full of spores, their air passages get irritated.
The irritation leads to coughing, congestion, and general discomfort. You do not want your children to get sick because of breathing spores-laden air from your poorly maintained humidifier.
Damages to the Humidifier
If the molds and spores find their way to the filter of your humidifier, they accumulate around this delicate component. With time, the accumulation of mildew and spores on the filter interferes with how the device functions. You will end up either replacing the filter or the entire device sooner than later if molds invade the filter.
How do I Make my Humidifier Mold-Free?
Making and keeping your humidifier free of molds can help you realize all the benefits of having a humidifier in the home. Because mold growth is one of the biggest problems associated with using a humidifier, you must ensure that spores of molds do not thrive inside your device.
Here are a few things that you can do to make your humidifier mold-free.
Replace the water in the tank daily
It is common for some water to remain in the water tank even if you let the humidifier run the whole day. Stagnant and stale water is the perfect breeding ground for spores of molds and bacteria.
To prevent the growth of spores in your humidifier, empty its water tank every day. Replace the stagnant water with fresh water before re-plugging your humidifier into the wall socket and running it.
Carry out routine cleaning
Regular cleaning of your humidifier helps to keep the mold and mildews at bay. Regular cleaning of the humidifier should be a long process.
You only need to clean the visible parts and check that everything is working well. Sticking to this simple procedure is vital for ensuring that your humidifier is free of mold.
Deep-clean the humidifier every week
Deep cleaning your humidifier entails disassembling it and thoroughly washing every part before reassembling it. The in-depth cleaning process gives you the chance to remove all the dirt and other particles that usually accumulate in humidifiers’ internal components.
This, in turn, prevents the growth of mold, mildews, and bacteria in your device.
Does Vinegar Kill Mold in Humidifiers?
Vinegar does not kill mold in humidifiers. Vinegar is used to remove the deposits of minerals that often accumulate inside the humidifier.
The mineral deposits accumulate if one uses hard water in the humidifier. It is always advisable to use demineralized water in your humidifier to prevent the accumulation of sediments.
The use of a mixture of vinegar and water in equal amounts helps one clean the humidifier’s internal components thoroughly. The mix of vinegar and water forces the deposits to come off the surface of your humidifier’s internal components.
You can then use a soft-bristled brush to remove the dirty mixture of vinegar, water, and mineral deposits.
How to Clean a Humidifier
Routine cleaning of your humidifier should be an easy process. However, some humidifiers have intricate designs that may make the standard cleaning process a herculean task.
For such humidifiers, disassembling and reassembling their components often takes a long time. Nevertheless, the steps of conducting routine cleaning of your humidifier are as follows.
- Turn off the humidifier and unplug it from the wall socket. This is a safety measure to ensure that you can freely and safely clean your humidifier’s inside parts.
- Empty the water tank. In most cases, humidifiers will have excess water in their tanks at the end of every day. It is advisable to empty the water every day and replace it with fresh water. This habit helps to prevent the growth of molds, which thrive in stagnant water. Before cleaning your humidifier, ensure that the water tank is drained of all excess water.
- Disassemble the humidifier. This step entails unlatching all the components of the humidifier. How quickly you can disassemble a humidifier depends on the design of the device. Devices with simple designs can be disassembled quicker than those with intricate designs.
- Disinfect your humidifier. Use a mixture of bleach water in the following ratio: one gallon of water (3.8 liters) with one teaspoon of bleach. You can use hydrogen peroxide instead of bleach. Pour the mixture into the humidifier and swirl it so that the mixture reaches all your humidifier’s internal surfaces. Let it rest for about 30 minutes.
- Use a mixture of water and vinegar to remove mineral deposits. Fill up the tank with warm water and a small amount of vinegar. Let the mixture rest for about 30 minutes again. Pour it and use your cleaning brush to remove deposits from all corners of the tank.
- Rinsing and drying. Rinse all the components if you need to so that they are immaculate. Spread them out on towels so that they can dry properly. You can then reassemble your humidifier and prepare to use it again.
