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.

How We Picked the Products

Methodology

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:

  • Quality: All the moisture absorbers on this list are made out of high-quality materials and come from reputable brands.
  • Longevity: I selected moisture absorbers that can last between 30 and 60 days. Some on this list are also reusable once reactivated in heat or sunlight, which helps extend their use.
  • Ease of Use: The moisture absorbers I chose are simple to use and do not require very much (if any) preparation or assembly.
  • Effectiveness: I looked at how good each moisture absorber was at eliminating excess moisture and bad odors.
  • Value: I chose reasonably priced moisture absorbers and included several options that come as multipacks, which makes them an even better value.

Things to Consider Before Buying a Moisture Absorber

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

Absorption Style

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.

Type

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.

Scent

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.

Quantity

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.
