Best Moisture Absorbers to Keep Your Home Dry

Moisture absorbers offer a convenient way to reduce humidity and keep your home dry. They work by collecting excess moisture from the air, which helps prevent mold and bad odors caused by water damage.

Moisture absorbers can be used in a variety of rooms where excess moisture is an issue, including bathrooms, basements, closets, and kitchens. They can also be used to cut down on the dampness in cars and boats.

Available in different sizes, scents, and containers, there are plenty of options to choose from. Here are our recommendations for the best moisture absorbers to suit a range of needs.

All moisture absorbers might seem similar, but there are some important factors that differentiate each product. To select the best moisture absorbers, I examined multiple criteria:

Why It Made The Cut: This fresh scent moisture absorber includes four refillable cups that can be used in different rooms of your home for up to 60 days of moisture protection.

DampRid moisture absorber cups trap excess moisture from the air and eliminate bad odors, resulting in cleaner and fresher air. Conveniently sold as a 4-pack, the refillable 10.5-ounce cups can be used in multiple rooms so you can reduce moisture throughout your entire home. Use them in bathrooms, laundry rooms, closets, or any other room that has too much moisture.

These moisture absorbers start working as soon as the lid is removed and odor-reducing crystals are poured into the container. Once the odor-absorbing crystals dissolve, you can pour out the water and refill it for longer-lasting freshness. Depending on the humidity levels and temperature in your home, each cup lasts up to 60 days.

Why It Made The Cut: These food-safe Dry & Dry silica gel packets are specifically designed for ultimate moisture absorption and heat resistance for rechargeability.

Looking for a versatile solution to fight dampness? You can these silica gel packets from Dry and Dry to protect food, medicine, vitamins, jewelry, books, electronics, and more from moisture damage. 

Items should be placed into a sealed container with the silica gel packets to keep out moisture. You can use one packet for containers up to 120 cubic inches, but more packets are recommended for better moisture protection. If the packets are left out in the air, they can become saturated right away and are not as effective. 

The pure white silica gel beads are food safe, and the packets are made out of high-quality coated paper that can be reheated in the oven or microwave for additional use. They come in a newly designed resealable storage bag with an airtight seal and extra layers for moisture protection.

These fragrance-free moisture absorbers have unique lock-wet paper to prevent accidental leakage. They also include an independent water-collecting layer that stops water from mixing with the calcium chloride particles. You can view the moisture absorption in real time by seeing how much water is collected in the box.

These compact moisture absorber packets are a perfect choice for closets, laundry rooms, bathrooms, and RVs. You can use more than one bag at a time for optimal moisture absorption or save the extras for future use. Each pack lasts up to 30 days, and should be thrown out when full.

These versatile bamboo air purifying bags from Vitscan can be used as moisture absorbers, odor eliminators, shoe deodorizers, and air fresheners. They’re made out of 100 percent bamboo, charcoal, and breathable fabric; the activated bamboo charcoal absorbs moisture and odors better than regular carbon due to its high-temperature activation process.

These eco-friendly moisture absorbers come in a convenient 12-pack with two different-sized packets so you can choose which is best for your space. Using more than one bag at a time is recommended to increase the absorption rate and eliminate odors more quickly. These natural air purifiers are safe to use around kids and pets. They can last up to two years and are easy to reactivate by placing them under the sunlight for two hours each month.

Here are some of the most important factors to consider when shopping for a moisture absorber.

There are different kinds of moisture absorbers, including calcium chloride and silica gel. Calcium chloride can effectively reduce moisture in areas with high humidity. Silica gel is made out of sodium silicate and is typically found as gel beads inside a fabric or paper packet.

The most common types of moisture absorbers are packets and containers. Packets are designed for smaller spaces and can either be dropped into a sealed container or hung up. Containers, which sometimes look like tubs of butter, are a better choice for large spaces.

Moisture absorbers come in a variety of scents, including fresh scent, lavender, and unscented. If you are sensitive to smells, you might want to opt for a fragrance-free option.

Before choosing the best moisture absorber, decide if you need just one or multiple. Many moisture absorbers come in convenient multipacks, which are a great choice if you have moisture issues in multiple rooms or you want to have extras on hand for future use. If you are just trying to take care of a moisture problem in one room, a single moisture absorber may be all you need.

We considered many different moisture absorbers when looking for the best solution to combat excess moisture. Our top pick is the DampRid Fresh Scent Refillable Moisture Absorber because it’s long-lasting, refillable, and comes in a multipack.
