What to look for in the best commercial dehumidifier for business?

Several factors come into play when purchasing a commercial dehumidifier for your business. Common ones include the size of the space, the amount of humidity, the local temperature, and the relative humidity you want to achieve. With that in mind, here are some features you should look out for.

  • Blanket: Dehumidifiers will have a coverage limit which is usually displayed in square feet. Going over your space is always the best option to avoid overstraining your unit.
  • Pint Capacity: This is the amount of humidity a dehumidifier can capture over a 24 hour period. The quart capacity should be based on the size of your space.
  • Temperature operation: Having a low operating temperature means you can remove moisture from your space in low or high temperatures. Find out the lowest and highest temperatures in your area before making a purchase.
  • Automatic functions: Auto on/off, auto restart in case of power failure, auto defrost and auto drain are valuable features to keep your unit running without too much supervision.
  • Built-in humidistat: With a built-in humidistat, you can adjust the relative humidity level in your space and the device will always maintain the level.
  • Noise level: The sound level of some commercial dehumidifiers can be high. Keep this in mind if it is operating in a space where many people work.

Dehumidifier Terms

ACH – Air Changes Per Hour: The ACH is the number of times air is pushed through the dehumidifier each hour. This lets you know how much airflow you need to dehumidify your space.

CFM – Cubic Feet Per Minute: The CFM tells you how much air the device can move. By multiplying the ACH level with the CFM and dividing the result by 60 minutes, you can determine the CFM you need for your space.

AHAM – Association of Appliance Manufacturers: This is used in dehumidifiers as the group recommends test conditions of 60% humidity and 80 degrees Fahrenheit. Indeed, the AHAM believes that it best represents the conditions in which the dehumidifiers will be used.

Saturation: This tests for 90% humidity and 90 degrees Fahrenheit, which is used to determine the maximum amount of humidity that can be extracted in a day.
