This guide will provide you with the key features and considerations to help you select the best Keystone dehumidifier for your needs.

Key Features to Consider

Capacity

  • Pint Capacity: Dehumidifiers are typically rated by the pints of moisture they can remove from the air per day. Consider the size of your space and the level of humidity to choose an appropriate capacity.
  • Room Size Compatibility: Make sure the dehumidifier’s capacity matches the square footage and typical humidity levels of the area you wish to dehumidify.

Humidity Control

  • Adjustable Humidistat: Allows you to set and maintain a desired humidity level, providing automatic operation and energy efficiency.
  • Hygrometer: Some models include a built-in hygrometer to monitor and display the current humidity level in the room.

Water Collection

  • Collection Tank: Assess the size of the water tank to determine how frequently it will need to be emptied.
  • Continuous Drain Option: Look for a continuous drain feature if you prefer not to empty the tank manually, ideal for high humidity areas or unattended operation.

Portability

  • Casters and Handles: Wheels and handles facilitate moving the dehumidifier between rooms or storage areas.
  • Compact Design: A smaller unit might be easier to integrate into your living space and store when not in use.

Energy Efficiency

  • Energy Star Rating: Models with an Energy Star rating ensure lower electricity consumption and cost, as well as environmental sustainability.

Noise Level

  • Operational Noise: Consider how quiet the dehumidifier is, especially if it will be used in living areas, bedrooms, or quiet environments.

Additional Features

  • Auto-Restart: Useful for returning to previous settings after a power outage.
  • Washable Air Filter: Easy-to-clean filters help maintain air quality and reduce the need for frequent replacements.
