Dehumidifiers remove moisture from the air to improve the overall indoor air quality and reduce the growth of allergens such as mold and dust mites. The use of air purifiers and dehumidifiers provide superior effectiveness in eliminating harmful mold spores and dust mites that lead to respiratory problems.

Access to moisture is critical for both mold and dust mite growth and the use of a dehumidifier is the best way to control them. Dehumidifiers that are rated at 70 pints or less are classified as small dehumidifiers and have casters for easy mobility. A dehumidifier that is larger than this is typically referred to as an industrial dehumidifier and while they have much higher capacities, they tend to cost much more and not fit into the décor of a residence.
