The DampRid� Moisture Absorber is made to help you breathe better. Mold and mildew generate musty odors, which this product removes. To improve airflow, the upper chamber incorporates 360-degree venting. It incorporates lid locks for added security, a vast, strong base, and a spill-proof construction to prevent spillage if the container tips over. Depending on the temperature, this absorber can last up to 60 days. This dehumidifier is safe for the environment, septic systems, houseplants, and animals.
