   Energy efficiency indicates how much energy a dehumidifier uses while operating. Look for units with the Energy Star label, which signifies reduced energy consumption. Energy-efficient models save money on electricity bills and are better for the environment. The U.S. Department of Energy reports that energy-efficient appliances can save users up to 30% on average energy costs.

4. Drainage Options:
   Drainage options involve how the collected water is disposed of. Types include manual drainage (emptying a tank) and continuous drainage (using a hose). Continuous drainage is convenient for larger spaces like 4250 square feet, as it reduces the need for frequent maintenance. According to a study by the Home Improvement Research Institute (HIRI), convenience is a significant factor in customer satisfaction with dehumidifiers.

5. Filter Type:
   Filter type refers to the filtration system used to capture airborne particles, such as dust and allergens. HEPA filters are highly effective in trapping small particles, improving air quality. Regular replacement or cleaning of filters is necessary for optimal performance. Poorly maintained filters can lead to inefficiencies and reduce the lifespan of the dehumidifier, according to research from the Environmental Protection Agency (EPA).

6. Noise Level:
   Noise level indicates how loud the dehumidifier is while operating. Many models list their noise levels in decibels (dB). For residential use, a unit with a noise level between 40-50 dB provides effective moisture removal while maintaining a comfortable living environment. Consumer Reports suggests that quieter models enhance user experience and reduce disturbance in living areas.
