The Best Whole

The E100C Pro ducted dehumidifier from AprilAire tops our lineup of whole-house dehumidifiers for quality, efficiency, and convenience. The E100C removes up to 100 pints of water from the air in a 24-hour period and is suitable for use in homes with up to 5,500 square feet of living space. The AprilAire E100 series has been tested and certified by Energy Star as being “most efficient,” meaning it’s among the best models for conserving energy while still providing high levels of indoor comfort and performance.

This dehumidifier installs on a home’s HVAC duct system, and professional installation is recommended. It features a single on/off switch, and the desired relative humidity (RH) level is programmed during installation, so there’s nothing for residents to adjust once installation is complete. Once set, the dehumidifier will sense and maintain the desired RH independently. Alternatively, a wired wall-mount controller (sold separately) can be connected to adjust the dehumidifier from a central location.

This AprilAire dehumidifier comes with caster wheels that are designed to make it easier to roll the unit into place on a hard surface, such as a concrete basement floor. There’s no water tank to monitor or dump—optimally, condensation is routed through a pipe or tube into the same drain the HVAC uses. However, if the unit is located in a spot with no drain, such as a crawl space, a separate condensate pump will be necessary to remove the collected water to a suitable drain.
