EDV4000H vs EDV4000 Specs
Moisture capacity
The EDV-4000H removes up to 14.81 pints of moisture per day. This specification defines how much water the unit extracts from the air daily. The EDV4000 data does not list a specific daily removal rate. For damp spaces requiring active water extraction, the higher capacity of the EDV-4000H offers a clear advantage. You can rely on the published pint-per-day figure to gauge performance in humid environments. The EDV4000 lacks this specific metric in the provided data, making direct capacity comparison difficult based on available specs alone.
Coverage area
The EDV-4000H covers up to 444 square feet, which equals 4,000 cubic feet of space. This rating helps you determine if the unit fits your room size. The EDV4000 data does not provide a square footage or cubic footage rating. If you need to dry a large crawl space or basement, the EDV-4000H’s stated coverage is a practical benefit. The EDV4000’s coverage is not listed, so you cannot verify if it handles larger areas effectively. The EDV-4000H provides clear guidance on suitable room sizes.
Drainage options
The EDV-4000H includes a 2-liter tank with an auto shut-off feature. It also supports a continuous drain hose for hands-free operation. This setup allows you to leave the unit running without checking the tank. The EDV4000 data does not mention a tank, auto shut-off, or drain hose. For unattended use in basements or crawl spaces, the continuous drain option on the EDV-4000H is a significant practical advantage. The EDV4000’s drainage method is not specified in the provided data.
Noise levels
The EDV4000 operates at 34dB on low fan speed and 51dB on high fan speed. These decibel ratings help you assess noise in living or working spaces. The EDV-4000H data does not list specific decibel levels for its fan speeds. However, both units use rotary desiccant technology, which typically runs quieter than compressor models. The EDV4000 provides exact noise data for your reference. The EDV-4000H lacks this specific measurement, making the EDV4000 slightly more transparent regarding acoustic performance.
Weight and size
The EDV4000 weighs 15 pounds with dimensions of 18 inches high, 11.5 inches wide, and 7 inches deep. The EDV-4000H weighs 13 pounds with dimensions of 18 inches high, 11 inches wide, and 7 inches deep. Both units are compact and fit through standard access hatches. The EDV-4000H is slightly lighter and narrower, which may ease placement in tight service areas. The EDV4000 is marginally wider. The difference in footprint is small, resulting in a tie for portability and space efficiency.
Special features
The EDV-4000H includes a dedicated clothes-drying setting and a built-in ionizer. It also operates at temperatures as low as 34°F, where compressor units fail. The EDV4000 data does not list these specific features. If you need to dry fabrics or improve air quality with ionization, the EDV-4000H offers more functionality. The cold-rated performance is also a unique advantage for unheated spaces. The EDV4000 lacks these listed extras in the provided data, making the EDV-4000H the more feature-rich option.
