What Features Should You Prioritize in a Low Energy Dehumidifier?
To prioritize features in a low energy dehumidifier, focus on energy efficiency, capacity, humidity control, noise level, and portability.
- Energy Efficiency
- Capacity
- Humidity Control
- Noise Level
- Portability
When choosing a low energy dehumidifier, it is essential to understand the significance of each feature.
-
Energy Efficiency:
Energy efficiency refers to the ability of a dehumidifier to remove moisture while using less electricity. This is typically measured in terms of energy factor (EF), which indicates the amount of moisture removed per unit of energy consumed. According to the U.S. Department of Energy, look for Energy Star-rated models, which use about 30% less energy than non-rated products. A study by the Lawrence Berkeley National Laboratory shows that Energy Star dehumidifiers can save consumers \$140 annually on energy costs. -
Capacity:
Capacity defines the amount of moisture a dehumidifier can extract from the air in a given timeframe, often measured in pints per day. Common capacities range from 30 to 70 pints. The right capacity depends on the size of the area and the humidity level. For example, a 70-pint dehumidifier is advisable for large basements prone to high moisture. According to the Association of Home Appliance Manufacturers, choosing the appropriate capacity can significantly enhance the unit’s performance and lifespan. -
Humidity Control:
Humidity control is the ability to set and adjust desired humidity levels for comfort and health. Most modern dehumidifiers come with built-in hygrometers and adjustable settings that maintain specific humidity levels. This feature allows users to optimize the indoor environment efficiently. A study in Indoor Air Journal highlights that maintaining indoor humidity levels between 30% and 50% can reduce mold growth and improve air quality. -
Noise Level:
Noise level is crucial for users planning to operate the dehumidifier in living spaces or bedrooms. Dehumidifiers can produce noise levels measured in decibels (dB). Models that operate under 50 dB are considered relatively quiet. The Consumer Product Safety Commission recommends quieter units for residential areas, especially for overnight operations. -
Portability:
Portability refers to the ease of moving a dehumidifier from one location to another. Features such as built-in wheels and convenient handles enhance mobility. For example, compact or lighter models can be easily transported to various rooms where moisture issues may arise. Research suggests that portable units can effectively manage humidity in multiple locations within a home, adapting to changing needs.
How Does Noise Level Impact Your Choice of a Low Energy Dehumidifier?
Noise level significantly impacts your choice of a low energy dehumidifier. When selecting a dehumidifier, consider its operational noise level. This feature is important for maintaining a comfortable environment, especially in quiet spaces like bedrooms and offices.
Low noise models typically operate between 40 and 50 decibels. This range is quieter than a normal conversation. If the noise level exceeds this, it can be disruptive.
Evaluate your specific needs before making a selection. If you require a dehumidifier for a living area, choose a model that prioritizes quiet operation. On the other hand, if the unit is for a basement or garage, where noise is less of a concern, higher noise levels may be acceptable.
Consider the type of compressor used in the dehumidifier. Rotary compressor units tend to be quieter than traditional models. Moreover, look for features like sound insulation and design, which can minimize noise during operation.
Assess customer reviews to understand the real-world noise performance of different models. This feedback helps identify effective low-noise options. Ultimately, balancing noise level with energy efficiency is crucial to ensure a comfortable environment while minimizing energy consumption.
What Capacity Do You Actually Need for Your Space?
To determine the capacity you need for your space, evaluate your specific requirements based on usage, space size, and environmental conditions.
- Assessing Usage Needs
- Room Size Considerations
- Environmental Conditions
- Types of Dehumidifiers

Assessing Usage Needs:
Assessing usage needs involves understanding the purpose of the space and the amount of moisture it generates. Spaces like basements, laundry rooms, or bathrooms often require higher capacity due to excess humidity from activities such as washing and showering. For example, humid climates demand larger units for effective moisture control.
Room Size Considerations:
Room size considerations refer to measuring the physical dimensions of the area that requires dehumidification. A larger space necessitates a dehumidifier with higher capacity. The Association of Home Appliance Manufacturers suggests that for rooms up to 1,500 square feet, a unit with a capacity of 50 to 70 pints per day is typically recommended. For smaller areas, a dehumidifier rated for 30 pints may suffice.
Environmental Conditions:
Environmental conditions include factors such as overall humidity levels and temperature trends in your location. High humidity areas, especially in tropical regions, may require units that can handle more moisture extraction to maintain comfortable indoor air quality. The U.S. Department of Energy states that ideal indoor humidity levels should remain between 30% and 50% for optimal comfort and health.
Types of Dehumidifiers:
Types of dehumidifiers categorize the appliances based on their method of operation. There are two main types: refrigerant (compressor-based) dehumidifiers and desiccant dehumidifiers. Refrigerant dehumidifiers are most efficient in warm conditions, while desiccant models perform well in cooler temperatures. Consumer Reports notes that the choice between types will impact both the capacity needed and energy efficiency.
Energy Efficiency Ratings:
Energy efficiency ratings refer to the energy consumption of a dehumidifier relative to its capacity. Units with the Energy Star rating are designed to use less energy while providing effective dehumidification. The Environmental Protection Agency highlights that selecting Energy Star certified models can lead to significant cost savings on electricity without sacrificing performance.
