Things to Consider While Choosing A Dehumidifier for Water Damage
  • Coverage Area

A dehumidifier with a 30-pint capacity covers up to 1500 square feet. While dehumidifiers with 40-50 pints capacity cover up to 2000 square feet. If you have spaces over 2000 sq. fit, then go for 60-70 pints dehumidifiers. A dehumidifier for flooded basements will have 40 pints or more capacity. 

  • Temperature Requirements

The recommended temperature to operate dehumidifiers is more than 60 degrees F. Or, the released moisture will freeze on the device’s coil, causing damage. Turn off the dehumidifier if the temperature goes below 65 degrees F. Naturally, you will need a dehumidifier when the outdoor humidity is high, specifically when the temperature goes above 60-70 degrees F.

During cold weather, especially when the air is dry you will not require a dehumidifier.

  • Daily Rate of Extraction

Both AHAM and saturation ratings classify dehumidifiers. AHAM ratings apply to average conditions like relative humidity levels of 60% and temperature of 80°F. While saturation ratings apply to extreme conditions like relative humidity levels of 90% and temperature of 90°F. If you want to use the dehumidifier to repair flood damage, consider the saturation rate.

  • Drainage

Generally, three types of drainage options are seen in dehumidifiers such as gravity drainage, an internal condensing pump, or an external condenser. Internal condensing pumps are the most common nowadays due to their convenience. If your one comes with an automatic drainage function, it is well enough.

Extra Features:
  • Noise Levels: Usually, dehumidifiers with an average noise level of about 40 to 50 dB are quiet enough.
  • Auto Reset: This lets your device auto-restart after the electricity goes off or a power outage or failure.
  • Built-in Humidistat: Control and monitor the moisture and humidity levels with it.
  • Front Sensor: Identifies the ice formation and auto-shuts down the compressor.
  • Filter Indicating Light: This lets you know that you need to clean the filter by lighting it up.
  • Digital Controls: Let you see and control temperature, speed, humidity, and more.
  • Warranty: Warranty differs from 1 to 5 years on various models.
  • Price:

You will get a suitable dehumidifier within the range of $ 600 to $1100 or more.
