Excess moisture can quickly become a nuisance in enclosed areas around the home. Wardrobes can develop musty smells, storage areas can feel damp, and bathrooms, laundries and cupboards can hold unwanted humidity.
A hanging moisture absorber provides a simple way to help manage excess moisture in these smaller spaces, without requiring electricity.
But how do they actually work, where should you put one, and how long do they last?
What Is a Hanging Moisture Absorber?
A hanging moisture absorber is a compact desiccant product designed to attract and collect moisture from the surrounding air.
The Pro-Ex Home Hanging Absorber (440g) with Hook contains 440g of spherical calcium chloride combined with nano moisture-locking paper. It can collect up to 800ml of moisture and last for up to 60 days, depending on the humidity and temperature of the space. Pro-Ex
Because it hangs from a hook, it can be placed inside wardrobes and other enclosed areas without taking up valuable shelf or floor space.
How Do Hanging Moisture Absorbers Work?
The key ingredient is calcium chloride.
Calcium chloride is hygroscopic and deliquescent, meaning it attracts moisture from the surrounding air. Scientific information compiled by PubChem confirms that calcium chloride absorbs atmospheric moisture and that the rate of moisture absorption can vary depending on factors such as humidity, temperature, surface area and air circulation.
Inside the Pro-Ex Hanging Moisture Absorber, the calcium chloride crystals begin attracting airborne moisture once the product is exposed to the surrounding environment.
As moisture is absorbed, the calcium chloride gradually dissolves. The resulting liquid passes into the lower collection chamber, where you can actually see the moisture that has been collected.
This makes it easy to monitor the absorber and know when it’s time for replacement.
Where Should You Put a Hanging Moisture Absorber?
Hanging moisture absorbers work particularly well in smaller, enclosed spaces where unwanted moisture and musty odours can accumulate.
Suitable areas include:
- Wardrobes and closets
- Cupboards and pantries
- Bathrooms and laundry areas
- Storage rooms
- Basements and garages
- Caravans and campers
For wardrobes in particular, the hanging design allows the absorber to sit alongside clothing without taking up drawer or shelf space.
Pro-Ex recommends the Home Hanging Moisture Absorber for these types of enclosed household areas.
How Long Does a Hanging Moisture Absorber Last?
The Pro-Ex Home Hanging Absorber can last for up to 60 days, but its actual lifespan will depend on the conditions where it is being used. Pro-Ex
A warm, humid environment may cause it to collect moisture more quickly than a cooler, drier space.
This is why you shouldn’t rely only on the number of days it has been hanging. Check the lower collection chamber regularly to see how much liquid has accumulated.
Do Hanging Moisture Absorbers Need Electricity?
No – and this is one of their biggest advantages.
Unlike an electric dehumidifier, the Pro-Ex Home Hanging Absorber requires no electricity, batteries or charging. Simply remove the outer packaging and hang the absorber in the desired location.
This makes it particularly convenient for wardrobes, cupboards, storage rooms, caravans and other areas where using an electrical appliance may not be practical. Pro-Ex
The Pro-Ex absorber is also fragrance-free, so it controls moisture without adding a fragrance to your wardrobe or storage space. Pro-Ex
When Should You Replace It?
Once the collection chamber is full, the hanging absorber should be replaced.
For the Pro-Ex product, the collected brine solution can be carefully drained according to the product’s disposal instructions. Pro-Ex advises snipping the corner, pouring the solution down a household drain, rinsing with water and washing your hands after handling. The empty bag can then be disposed of with normal household waste. Pro-Ex
Always follow the instructions provided with the product and avoid opening or damaging the bag while it is in use.
