Mold can pose a significant health problem.

Excess moisture causes a host of problems in your home. For example, excess moisture in your bathroom may cause mold or mildew growth, peeling or blistering of paint, wood rot, insect infestation, musty odors and condensation. Among these, mold growth is perhaps the most serious, as mold growth can lead to significant health problems, including skin irritation and respiratory problems. However, there are several ways to absorb moisture in a room.


Step 1

Hang cloth bags filled with silica gel, activated alumina or molecular sieves. These chemicals absorb moisture from the air. Keep in mind, however, that these chemicals are not available in department stores. Contact your local science teachers or a large supplier of industrial chemicals.

Step 2

Place anhydrous calcium chloride granules in a small container made of non-rusting screen or waxed cardboard perforated with small holes. Place the small container in an enameled pot and place the pot in the room. The pot is necessary because as the anhydrous calcium granules absorbs moisture, it liquefies.


Step 3

Run a dehumidifier. Dehumidifiers remove moisture from the air. Dehumidifiers are particularly effective in enclosed rooms, such as closets and basements, that cannot easily be ventilated.
