Dehumidifiers are machines that remove excess moisture from the air in residential or business buildings. The moisture is deposited into a bin within the machine or goes through a hose attached to a drain. Homes in humid climates often need dehumidifiers to maintain recommended humidity levels.
A home or room is less likely to see mold, mildew and dust mite develop when excess moisture is removed. People with allergies are especially prone to health risks from these contaminants. Dehumidifiers come in various sizes and price points. Condensation on walls, rotting wood, window condensation and musty smells are signals of excess moisture problems.
