Part of the e-series line of dehumidifiers, the AprilAire E100 is one of the most energy-efficient models to date. Recognized as the Most Efficient of ENERGY STAR® 2021, it is ideal for dehumidifying your basement, sealed crawl space, or whole home. The E100 removes up to 100 pints (12.5 gallons) of moisture from the air per day. This helps keep your home’s humidity in the ideal range of 40-60% relative humidity to fight viruses, bacteria, mold, and other airborne pollutants.
