To make a DIY moisture absorber just like DampRid, place calcium chloride (sold as sidewalk de-icer at hardware stores) in a container with a way to separate the crystals from the liquid. As it pulls humidity from the air, the crystals dissolve and the resulting liquid drips into a reservoir below.
The cheapest and most effective homemade moisture absorber uses calcium chloride (sold as bulk driveway ice melter) combined with a simple two-bucket or colander-over-bowl system. This DIY approach costs a fraction of commercial products like DampRid and works identically to pull water from the air.
Making a DIY DampRid container is incredibly easy and saves you a ton of money. The main active ingredient in commercial moisture absorbers is calcium chloride (the same compound used in ice-melting pellets).
You can also buy a large bag of calcium chloride de-icer, it comes in 20-50 lb bags. This will replace the crystals in the damp-rid tub when it gets soggy.
The active ingredient in DampRid is calcium chloride (typically making up about 78% to 80% of the formula).
Apparently it's calcium chloride- also cheap. Its filled with calcium chloride, it will absorb moisture better that rock salt. Calcium chloride is a deicer that can be bought by the bag in the winter for snow.
To make a DIY moisture absorber, place materials like rock salt, baking soda, or calcium chloride (often sold as ice melt) in a container with drainage holes placed over a collection tub. These materials draw humidity from the air in enclosed spaces, such as closets, basements, or cabinets.
Rock salt: Place bowls of rock salt in damp areas like closets or basements. It draws in moisture and requires no energy. Charcoal briquettes: Like rock salt, they absorb humidity and can be placed discreetly around the home.
Moisture Absorber Refill is for refilling spent moisture absorbent that comes in... DampRid 7.5 lbs. Moisture Absorber Refill is for refilling spent moisture absorbent that comes in their bucket products. DampRid is a great product, no hassle it dissolves and just disappears as its used up.
DampRid helps prevent mold by absorbing excess moisture from the air, which deprives mold of the humidity it needs to grow. However, it is a passive desiccant and best suited for small, enclosed spaces like closets or cabinets; it cannot replace proper ventilation or a powered dehumidifier for whole-room mold prevention.
To draw moisture out of a room, use a dedicated dehumidifier, or natural absorbers like DampRid, calcium chloride, and baking soda. Active methods include ventilation with fans, air conditioning, and placing desiccants like silica gel in enclosed spaces.
There are many silica packet alternatives, including DIY moisture absorbing sachets. Activated Charcoal: This is a popular alternative to silica gel sachets. It works by adsorbing moisture and odours from the surroundings.
Rock salt naturally absorbs moisture, making it perfect for DIY projects. It's effective in reducing humidity and is simple to set up, providing a cost-efficient option for your home. Materials and Tools Needed: Rock salt.
Tips for Reducing Humidity in Your Home Without a Dehumidifier
To tackle excess moisture in a crawl space, use materials that effectively absorb and control humidity. Rock salt is a natural desiccant. Place containers of rock salt in strategic locations to absorb excess moisture from the air.
Calcium chloride
Calcium chloride works very similarly to rock salt in the way that it draws moisture out of the air. If you're wondering where you could get your hands on this chemical compound, it's readily available at supermarkets and other stores thanks to popular brands like DampRid, Hippo and DampFree.
The liquid in DampRid is a saltwater brine (a solution of water and calcium chloride). It forms when the product's active ingredient—a white, crystalline salt called calcium chloride—absorbs excess humidity from the air and dissolves.
Replace DampRid crystals when they have completely dissolved into the bottom collection chamber.
Create a highly effective, budget-friendly moisture absorber using common household supplies like calcium chloride (the active ingredient in products like DampRID) or rock salt. Simply suspend your desiccant in a perforated container over an empty reservoir so the trapped humidity can drain as it melts.
Moisture is drawn out by desiccants (moisture absorbers), mechanical appliances, and proper air circulation. The specific agent depends on what you are drying.
DampRid is primarily made of calcium chloride (an inorganic mineral salt), which acts as a desiccant to absorb excess moisture from the air.
Several common household items can act as natural moisture absorbers. Items like baking soda, rock salt, charcoal briquettes, and leftover silica gel packets effectively pull humidity from the air in smaller, enclosed spaces like closets, cabinets, and basements.
How to make an odor removal solution: Mix equal parts of white vinegar and water in a spray bottle. Use this solution to wipe down surfaces or spray into the air to neutralize odors. The vinegar smell dissipates quickly, taking unwanted odors with it.
To make a DIY dehumidifier at home, create a passive moisture trap by placing hygroscopic desiccants like calcium chloride (e.g., rock salt) or activated charcoal inside two stacked plastic containers. The salt absorbs moisture from the air and drips harmlessly into the bottom reservoir.
