Description

AprilAire helps make your home a Healthy Air environment with the E100PZ 100-Pint Dehumidifier. This whole-house dehumidifier removes up to 100 pints (12.5 gallons) of moisture per day, delivering high-capacity moisture removal with energy-efficient performance in homes up to 5,500 sq. ft. Earning ENERGY STAR Most Efficient for 2024, this dehumidifier keeps your home in the ideal relative humidity range of 40–60% by removing moisture in your basement, crawl space, sealed attic, and throughout your home. Whole-house dehumidification helps prevent mold and odors, and helps fight viruses, bacteria, and other airborne pollutants. With built-in digital controls and a display screen for simple setup and programming, you can get up and running fast. The bucketless design removes moisture through an existing pipe or drain, meaning it never has to shut off to wait for the water bucket to be emptied. It stays powered on until the desired humidity level is reached. In addition to moisture removal, the unit can be set to circulate the air within your crawl space to even out relative humidity in that moisture-prone area. The AprilAire E100 Dehumidifier includes a 6-year warranty (5-year full replacement + 1-year parts) and it's designed and assembled in the USA utilizing US and global components, with corrosion-resistant aluminum coils. It offers multiple options for attaching the unit to your existing ductwork, and the low-noise operation ensures you'll enjoy the benefits of balanced humidity throughout your living space with no interruptions. This bundle includes a condensate pump for applications where the dehumidifier is not near a drain, and a hanging kit for easy installation in areas prone to standing water or where floor space is limited.
