How these alternatives compare
AprilAire 100-Pint Dehumidifier with Casters
The AprilAire E100C matches the E100 Pro with 100-pint daily moisture removal and Energy Star Most Efficient certification. It covers the same 5,500 square feet. The main difference is the inclusion of casters for mobility. The E100 Pro is designed for permanent installation near a drain. The E100C allows you to move the unit if needed. Both share identical dimensions and weight. If you need high capacity but want the flexibility to reposition the dehumidifier, this model fits your needs. It removes the hassle of emptying a water tank while keeping the same performance standards.
AprilAire 80-Pint Smart Whole-House Dehumidifier
The AprilAire E080W Smart offers 80 pints of daily removal, which is lower than the 100-pint E100 Pro. It covers up to 4,400 square feet. This model includes Wi-Fi connectivity and a built-in condensate pump. The E100 Pro relies on gravity drainage. The E080W allows installation in areas without a natural drain slope. It is lighter at 63 pounds. If you need smart control and a pump for difficult drainage locations, this is a practical choice. You sacrifice some capacity and coverage area for these added installation conveniences and connectivity features.
AprilAire 130-Pint Dehumidifier with Casters
The AprilAire E130C Pro provides 130 pints of daily moisture removal, exceeding the E100 Pro. It covers up to 7,200 square feet. This unit is larger and heavier at 98 pounds. It includes casters for movement. The E130C is designed for very large spaces or commercial use. It maintains Energy Star certification. If you have a larger home or high humidity levels, this model handles the extra load. You pay for increased capacity and a more robust build. The trade-off is a significantly larger footprint and weight compared to the more compact E100 Pro.
KNKA 80-Pint 5,500 Sq. Ft. Dehumidifier
The KNKA 80-Pint dehumidifier offers 80 pints of daily removal for up to 5,500 square feet. It is Energy Star certified. Unlike the AprilAire models, this unit requires a separate external tank for continuous drainage. The tank is not included. It is much lighter at 5.51 pounds. The dimensions are smaller in width and length. This model is suitable for large basements where portability is key. You gain a compact, lightweight unit. You lose the integrated, hassle-free drainage system of the AprilAire E100 Pro. You must manage the external tank setup yourself.
Waykar 80-Pint Energy Star Dehumidifier
The Waykar 80-Pint dehumidifier removes 80 pints of moisture daily for spaces up to 5,500 square feet. It is Energy Star certified. It weighs 27.2 pounds, which is heavier than the KNKA but lighter than the AprilAire units. It lacks the whole-house integration of the E100 Pro. It is designed for single rooms like basements or bedrooms. The dimensions are compact. If you need a portable solution for a specific large room, this works. You give up the continuous, whole-home drainage and smart sensing of the AprilAire. It is a standalone unit for targeted humidity control.
Bufanli 100-Pint 6,000 Sq. Ft. Smart Dehumidifier
The Bufanli 100-Pint dehumidifier matches the E100 Pro with 100 pints of daily removal. It covers up to 6,000 square feet. It is Energy Star certified. This model features smart app control. It lacks casters, making it less mobile. The tank size is smaller, limiting continuous operation without manual emptying. It weighs 31 pounds. If you want high capacity with smart connectivity, this is an option. You sacrifice the built-in pump or easy drain connection of the AprilAire. You must monitor the tank closely. It is best for users who prioritize app control over integrated drainage convenience.
