How Much Does A Commercial Dehumidifier Cost?

Commercial Dehumidifier

When it comes to controlling humidity levels in your commercial establishment, there are several factors you will want to consider. The size and type of the dehumidifier required is important for estimating its cost.

Industrial / commercial dehumidifiers can start at $5,500 and their price can go higher depending on their capacity or features such as wheels that make moving them easier than most.

For smaller businesses, ‘whole-house’ dehumidifiers which usually don’t exceed $2,000 for 260 pint capacity are a great option.

Commercial establishments are designed with the goal of keeping air conditioning and heating costs low. One consequence can be a build-up of moisture within the commercial space, which has been shown to cause respiratory problems like asthma or allergies for those who work in these environments.

A suitable dehumidifier will resolve these issues and could even lower the running costs of your HVAC appliances.

Dehumidifier Capacity

Pick the best commercial dehumidifier for your needs. You should look at how much water it can extract in 24 hours, but cost will obviously go up as moisture removal capacity gets higher.

Moderate Dampness

For moderately humid climates, you need a commercial dehumidifier with at least a 10 pint capacity for an area of 500 square feet. This means that the machine can remove 10 pints of water from your office in 24 hours. A rating of 4 additional pints will be needed for every additional 500 sq. ft to keep up due to humidity and moisture build-up.

High Dampness

The commercial grade dehumidifier should be able to extract at least 12 pints of water for 500 square feet in very damp conditions. For the best experience, it is recommended that you have an extra 5 pint capacity for every additional 1,000 sq. ft of space in your office building due to its high level moisture content.

Wet Conditions

For very wet conditions, the commercial dehumidifier should have a capacity of 14 pints for an area measuring 500 square feet. For larger areas, you will need 6 additional pints per additional 500 sq. ft.

Very Wet and Humid Conditions

The dehumidifier should be able to provide enough moisture removal for very wet conditions which means 16 pints for an area of 500 square feet. For larger areas, the dehumidifier will need at least 7 additional pints of capacity for each extra 500 sq. ft area.


ACH refers to air changes per hour. This relates to the number of times that air passes through the dehumidifier per hour.

Final Verdict

Dehumidifiers work best when they are correctly sized for their environment. Calculate your internal floor space and then choose the correct model for the job.

In most instances, $5000 is the most you will be required to spend.
