The Eva-Dry Dehumidifier is a dehumidifier that is designed to help persons who have allergies or for anyone who is adversely affected by the presence of moisture in musty places. This basement dehumidifier is very small but powerful enough to service an area of 250 square feet. Protects homes from growing mold spores and moisture-liking bacteria. Does not need water poured into it because it automatically grabs the moisture out of the air through non-toxic water-glass crystals inside the home dehumidifier. When the home dehumidifier indicator signifies that they are full, simply plug the unit into any household outlet to rejuvenate the crystals. This process takes about 12-14 hours to complete. No batteries. Each dehumidifier includes a hanger for the rod attachment. Lightweight.
