Mould will easily grow and spread if the right conditions are present. So, dehumidifiers don't kill mould, but they can help to prevent it from growing inside your home by reducing humidity. However, the best way to deal with it is to get rid of its source.
But while dehumidifiers may be slightly better for dealing with mould by getting rid of the humidity it needs to grow, air purifiers are also useful for preventing allergic reactions to mould spores. Overall, if you have a mould problem at home, both of these two machines in tandem will make the most difference.
Preventing Mold and Mildew
One of the great benefits of using a dehumidifier is that it helps prevent mold and mildew development in your home. Conversely, your dehumidifier becomes the target for mold, mildew, fungi and bacteria growth on the coil, in the holding tank, the filter and other parts.
When you walk into your home, you want it to smell clean and fresh. Moisture in the air tends to hold and trap odor, Bautista says. A dehumidifier will dry out the air and take away this moldy scent.
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. If you have a mold problem in your home, don't wait. Mold spreads as long as it has a water source.
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.
How Long To Run Your Dehumidifier? So to recap, run your dehumidifier unit for at least 12 hours a day. This is a good rule of thumb. Again, it's okay if you don't stick to this schedule every day, but be aware that the more your family runs your dehumidifier unit the fresher and cleaner it will be all year long.
Can I leave the dehumidifier running at night? Yes, we recommend using a dehumidifier 24hrs, however, be aware that there will always be a noise generated from the machine when it is operating.
Should a Dehumidifier Run Constantly? No, your dehumidifier should not have to run constantly to regulate the air humidity. An optimal humidity level to shoot for is between 30 and 50 percent. Your dehumidifier should reach this in 8 to 12 hours.
Hydrogen peroxide kills mold spore on contact by breaking down proteins and DNA. It's normally used to clean mold on porous and non-porous surfaces. Ionized hydrogen peroxide can kill mold spores in the air, but it requires the use of a special fogging machine.
Dehumidifiers work by removing moisture from the air. This can help to reduce condensation on walls and prevent mould and mildew growth. However, dehumidifiers will not necessarily dry out damp walls. If your walls are damp, you may need to use a combination of a dehumidifier and a fan to help dry them out.
The simple answer to whether they use a lot of electricity is yes. Even though the wattage or energy consumption of many models is low (The average being 483 watts), they stay on for at least 12 hours a day and in most cases, 24 hours, which is why the costs can increase, particularly for less efficient models.
You want to place your machine in an area where there is good air circulation so the unit can efficiently work. We do not recommend placing a dehumidifier directly against a wall or piece of furniture. Instead, put it at least six inches away from these vent-blocking surfaces.
The answer is no, dehumidifiers don't have the capacity to kill mold. Mold grows by reproducing spores into the air. Those spores land on surfaces and if there's moisture, food, and space, the mold spores will grow.
The size of the room, the humidity level, and the extent of the water damage are some of the variables that affect how long a dehumidifier takes to dry out a room. A dehumidifier typically needs between 24 and 72 hours to completely dry out a room.
Most dehumidifiers should not be operated in temperatures below 60° F, since the moisture removed from the indoor air can freeze when it condenses on the cooling coils, which can damage the unit.
Can you dehumidify too much? There is a chance of dehumidifying your home too much with a dehumidifier, especially if you are leaving your dehumidifier running for several hours on a timer unattended. Over-dehumidifying your home can lead to an increased chance of respiratory illnesses and dry and cracked skin.
As the name implies, this can treat an entire house. They can be standalone in the basement, or they can be installed into your duct system. The Aprilaire 1850 Dehumidifier, for instance, can remove up to 11.9 gallons of water per day.
With open windows, you are guaranteed at least some additional airflow and circulation. While airflow and circulation help get rid of moisture on their own, they also introduce more air into the inside environment. Dehumidifiers work best in a sort of “closed-loop system,” where the same air stays in.
If your dehumidifier's water basin is filling up too quickly, you probably have extra water in the air due to an issue like a cracked pipe, water leak or open crawl space. If you're hardly getting any water in the basin, you may need to simply turn the control to a drier setting.
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.
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).
Exposure to damp and moldy environments may cause a variety of health effects, or none at all. 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.
