Buying Guide for the Best Commercial Dehumidifier

When in the market for the best commercial dehumidifiers, it’s essential to look beyond just the basic features. Understanding the full range of functionalities can significantly impact your satisfaction with the product. Here, we explore with some critical factors:

1. Floor Area

Why it Matters: The floor area coverage of a dehumidifier indicates the maximum space size it can effectively work in. Choosing a dehumidifier with an appropriate coverage area is vital to ensure it can handle the volume of air in your space and maintain optimal humidity levels.

What to Look For: Dehumidifiers specify their coverage area in square feet. Options range widely, from models suitable for small spaces of around 1000 square feet to those capable of covering large areas up to 8000 square feet. Assess the size of the space where you plan to use the dehumidifier to ensure you select a model with adequate coverage.

2. Humidity Removal Rating

Why it Matters: The humidity removal rating, typically measured in pints per 24 hours, indicates how much moisture the dehumidifier can extract from the air. A higher rating means the unit can remove more moisture, making it more effective in highly humid conditions or larger spaces.

What to Look For: Commercial dehumidifiers can vary significantly in their moisture removal capabilities, with ratings ranging from 70 to 150 pints per day. Consider the typical humidity levels in your area and the size of your space to determine the necessary capacity. Higher capacity models are preferable for extremely humid environments or larger spaces.

3. Drainage System

Why it Matters: Given the volume of water commercial dehumidifiers can collect, an efficient drainage system is essential to prevent the water tank from needing constant manual emptying. An effective drainage system ensures continuous operation without interruption.

What to Look For: Commercial dehumidifiers usually offer gravity draining or continuous drainage options. Gravity draining requires the unit to be placed higher than the drainage point, while continuous drainage systems can pump water away from the unit, allowing more flexibility in placement. Consider the layout of your space and accessibility to drainage points when choosing between these systems.

4. Controls

Why it Matters: The control system of a dehumidifier determines how easily you can set and manage its operation. Advanced controls can offer greater flexibility and precision in humidity management, directly affecting the unit’s effectiveness and convenience.

What to Look For:

Digital vs. Analog: Modern dehumidifiers often feature digital controls with LCDs for precise humidity regulation, compared to the less precise dial controls of analog models.

Programmable Settings: Look for units with timers, humidity level settings, and modes such as continuous operation or targeted humidity levels to tailor the device’s operation to your specific needs.

5. Fan Speed and Noise

Why it Matters: Fan speed affects how quickly a dehumidifier can circulate air and reduce humidity. However, higher fan speeds can also produce more noise, which might be a consideration in noise-sensitive environments.

What to Look For:

Adjustable Fan Speeds: Models with multiple fan speed settings offer flexibility in balancing moisture removal speed and noise level.

Noise Level (dB): Noise is typically measured in decibels (dB). Look for units with noise levels that are acceptable for your environment. Commercial dehumidifiers can range from around 50 dB (comparable to a quiet office) to over 60 dB (comparable to normal conversation).

6. Temperature Limit

Why it Matters: Dehumidifiers have optimal operating temperature ranges. Performance can decrease outside of these ranges, making it crucial to choose a unit that is effective in the specific temperature conditions of your space.

What to Look For:

Operating Temperature Range: Check the specified temperature range, which can vary widely, e.g., from 36°F to 90°F. Ensure the dehumidifier’s range matches your typical environmental conditions.

Auto Defrost: In cooler conditions, units with an auto defrost feature prevent ice buildup on coils, maintaining efficiency and prolonging the device’s lifespan.

7. Warranty

Why it Matters: A warranty can provide peace of mind and protection for your investment. It reflects the manufacturer’s confidence in their product’s durability and their commitment to customer satisfaction.

What to Look For:

Length of Warranty: Commercial dehumidifier warranties can vary, typically ranging from 1 to 5 years. Longer warranties may offer better protection and value.

Coverage Details: Understand what the warranty covers (e.g., parts, labor, or both) and any actions that could void the warranty, such as improper installation or maintenance.


Concluding this article, we have highlighted some of the top commercial dehumidifiers currently on the market, detailing their features along with their advantages and disadvantages. This information is designed to help you make an informed decision.
