As you may know, traditional dehumidifiers use calcium chloride to collect moisture from the air. This unique chemical compound is known to dry out high levels of humidity. Here’s the problem: the dangers of calcium chloride desiccants to human health are extreme and can even lead to burns in the mouth and throat.
Obviously, calcium chloride is a dangerous substance to have in your home. In fact, it can cause damage to people, pets, and even property! So, how can you avoid the dangers of calcium chloride?
In this article, we will discuss the ins and outs of calcium chloride in traditional dehumidifiers and how desiccant dehumidifiers are a better solution for all of your humidity home problems.
Keep reading to learn how to avoid the potential dangers of calcium chloride dehumidifiers.
What is Calcium Chloride?
Also known as calcium salt, calcium chloride is a type of salt that is edible in small amounts. Typically, the substance is used in canning and pickling since it has an extremely salty flavor and can help preserve food. Calcium chloride is also used in traditional home dehumidifier systems to trap water molecules and eliminate high levels of humidity.
However, the dangers of calcium chloride are classified as severe if one is exposed to above-average levels. In fact, the chemical is an extreme irritant for the eyes, skin, and respiratory system.
While some brands try to tout the effectiveness of calcium chloride and its level of absorbance, you have to ask yourself, “is it worth risking my family’s health?”
Health Hazards of Do-It-Yourself Dehumidifiers
Some “do-it-yourself” and other powered dehumidifiers rely on fans to circulate air over calcium chloride salts. This exposes the air to minimal amounts of this chemical. Not so bad, right?
Here’s the catch: over time, long-term exposure to calcium chloride and its dust can cause lung damage, as well as other respiratory issues in the nose and throat. It can also cause skin irritation and contaminate clothing.
The dangers of calcium chloride are so extreme that The US National Library of Medicine (NIH) even strongly warns against the use of calcium salt:
“Inhalation causes irritation of nose and throat. Ingestion causes irritation of the mouth and stomach. Contact with eyes (particularly by dust) causes irritation and possible transient corneal injury. Contact of solid with dry skin causes mild irritation; strong solutions can cause marked irritation, even a superficial burn.” (source)
As you can see, dehumidifiers that use calcium chloride should not be used in the house. But, we’re not stopping there! This hazardous chemical can also destroy your property.
Don’t Use Calcium Chloride Desiccant Dehumidifiers in Vehicles or Gun Safes
Listen up! This is important: calcium chloride is exceptionally corrosive to metal. Overall, the salt eats away at the metal and rusts any metal inside the safe. Therefore, you should never dehumidify your gun safe, car, or other places where metals are stored with calcium chloride dehumidifiers or crystals.
For the same reason, it’s a good idea to avoid calcium chloride for boats and RVs. While many marine surfaces are resistant to corrosion, extended exposure to this chemical can present a problem.
So while calcium chloride might absorb damaging excess moisture faster than alternatives, you are just replacing one hazard with another.
So, what’s a simple solution? renewable desiccant dehumidifiers, of course!
A Safer Alternative: Renewable Desiccant Dehumidifiers
In contrast to calcium chloride salts, a renewable desiccant dehumidifier is safe, and is an incredibly effective way to remove unwanted moisture from an environment. Here’s the best part: unlike Calcium chloride, which usually requires air to be circulated over the chemical, renewable desiccant dehumidifiers do not need air circulation to work.
How Do Renewable Desiccant Dehumidifiers Work?
Desiccant beads have multiple small holes that create a large surface area on a tiny object. The more surface area something has the greater the moisture absorption rate. The renewable desiccant dehumidifier creates an entrance for air to come in and then the beads absorb the humidity.
What makes it so special, is unlike alternative dehumidifiers, desiccant dehumidifiers are non-electric. Additionally, these beads are reusable making them a lot more eco-friendly than the traditional calcium chloride options.
Additional Benefits of Desiccant Dehumidifiers
- Do not rust metal like calcium salt
- Wick moisture from the atmosphere more effectively
- Are reusable and therefore have an indefinite shelf-life
- Work with less material and fit in small spaces
And what’s more? Desiccant dehumidifiers are even reusable! Great for the environment and for your health. It’s a win-win!

I live in a shack by the road. Its hotter inside than out. 8 months out cf. the year. The other 4 months are colder than fishing north of Lake Placid in Febuary. We have no AC because itsworthless and costly. We live on two45 amp. Fuses .what’s the best way to keep corrosion off my 38 and 22 pistols as well as my rifle shells ,22 LR. Placed them once in a nice gun belt and corrosion ruined them all. Even in our safe our rifles are getting moldy.the tub of silicon beads to soak up moisture got dumped over.(someone forgot about it) so a tub which hold. The water isnt a safe bet here.
I have a (fairly) airtight chisel drawer where I keep all my chisels to prevent them from rusting. Inside the drawer I keep a metal tin with small holes poked in the top. inside the tin, I keep a wad of folded paper towel soaked in mineral spirits. Every few months I re-soak the towel. should work for any ferrous metals.
