Dehumidifiers for rooms without electricity
What do you do if you want to dry something, but don't have electricity?
If you want to get it really dry, you should use a dehumidifier. If you don't have access to electricity, you can use a moisture absorber bag. It's better than doing nothing.
How to use a power-free moisture absorber?
- The moisture absorber contains a salt that absorbs moisture.
- When the salt has absorbed so much moisture that it becomes wet, the water drips into a container beneath the moisture absorber.
- After a few weeks or months, the moisture absorber loses its effectiveness, and you need to replace it with a new one.
Areas of use for moisture absorbers
This type of moisture absorber is used where you want to control humidity, but do not have access to electricity. Moisture absorbers are used in places like:
- Boat
- Motorhome
- Caravan
- Basement
- Sheds and outhouses
- Closets
- Car
- Garage
Benefits of moisture absorbers
Moisture absorbers are used to avoid the problems that moisture can cause over time. These problems include:
- Basement smell
- Boat smell
- Mold
- Rot
- Mildew
- Musty smell
- Rust, corrosion, and deterioration
The advantage of this type of moisture absorber is that you don't need access to electricity. A powered dehumidifier will always provide a better result, but if you cannot use electricity where you have a moisture problem, this will be a good alternative.
How long does a moisture absorber last?
This depends on several factors, such as humidity and temperature, as well as how much water needs to be removed from the air. In a small, sealed closet, it will last longer than in a well-ventilated boat.
Normally, a moisture absorber lasts for 1 to 2 months, but keep an eye on it and adapt its use to your conditions.
Disadvantages of salt-based moisture absorbers
The water collected in the container beneath the salt is a brine. This can be chemically aggressive, and you should handle it with care. Be careful not to spill it on yourself or the interior. Rinse thoroughly with water if you spill, and remember that it's "just" salt.
Some customers find this brine messy, while others love the effect and buy these moisture absorbers again and again. Give it a try and see what you think.
What does the moisture absorber contain?
Moisture absorbers from different manufacturers contain slightly different chemicals, but primarily it is a salt of the type calcium chloride. You should avoid getting it in your eyes, mouth, and on your hands, but otherwise, it is considered completely safe.
Other names for moisture absorbers
We call this solution a power-free moisture absorber. The same principle also goes by other terms. These can be names like moisture eater, dry ball, dehumidifier, air dehumidifier, moisture agent, desiccant, drying agent, and similar. Common to all of them is that they use a salt to attract moisture from the air and then release it into a container beneath the bag.
