Dehumidifiers remove excess moisture from the air, drying out humid or excessively humid environments. Specific allergens require appropriate ecosystems to reproduce and thrive; dust mites, for example, need at least 65% humidity to thrive. Eliminating moisture in your home can help minimize common allergy triggers such as pet dander, mold, pollen and dust mites that can cause itchy or irritated eyes, wheezing , sneezing and even chest pain. A dehumidifier can easily maintain the predetermined level of humidity you desire, making your room unappealing to these allergens. This regulation of humidity levels can also protect important documents or musical instruments from damaging humidity and prevent the growth of bacteria, mold or mildew.

Dehumidifiers vary in size, capacity, and available features. Small, compact dehumidifiers can be ideal for managing humidity in smaller spaces like bathrooms, crawl spaces, RVs, and children’s bedrooms. Since they are portable, moving them from room to room is a simple and straightforward task. However, finding the best small dehumidifier for your home or RV is not an easy choice.
