What to Look for in the Best Commercial Dehumidifier for Business?

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

  • Coverage: Dehumidifiers will have a coverage limit which is generally posted in square feet. Going over your space is always the best option to avoid overworking your unit.
  • Pint Capacity: This is the amount of moisture a dehumidifier can capture in a 24-hour period. The pint capacity should be based on the size of your space.
  • Temperature Operation: Having a low operating temperature means you can remove the moisture in your space at low or high temperatures. Find out the lowest and highest temperatures in your location before you make a purchase.
  • Auto Features: Auto on/off, auto restart when the power goes out, auto defrost, and automatic drainage are valuable features to keep your unit operational without too much supervision.
  • Built-in Humidistat: With a built-in humidistat you can set the relative humidity level in your space and the unit will always maintain the level.
  • Noise Level: The noise level of some commercial dehumidifiers can get high. Keep that in mind if it is operating in a space where there are a lot of people working.

Dehumidifier Terms

ACH – Air Changes Per Hour: The ACH is the number of times the air is pushed through the dehumidifier every 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 unit can move. By multiplying the ACH level with the CFM and dividing the result by 60 minutes you can figure out the CFM you need for your space.

AHAM – Association of Home Appliance Manufacturers: This is used in dehumidifiers because the group recommends testing conditions of 60 percent humidity and 80 degrees Fahrenheit. This is because the AHAM believes it best represents the conditions dehumidifiers will be used in.

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