Finding Your Ideal Office Dehumidifier

There are a few things to keep in mind when looking for the right dehumidifier to fit your space’s needs. Here are the main things to look for:

Dehumidifier Size

The dehumidifier’s capacity and the size of your room, as well as your room’s current humidity levels, are all necessary considerations before purchasing this appliance. 

Figure out the square footage of the room where the unit will be put and the amount of moisture the specific dehumidifier can collect in 24 hours. If your space gets extremely humid, you will want to look for a high-capacity dehumidifier. Also, if you have a smaller room, you should opt for a dehumidifier unit that is relatively smaller in size, so it doesn’t take up much space.

Ease of Use

The noise levels of the dehumidifier are a big consideration for many buyers when choosing a unit.

Consider a dehumidifier with a sound level equivalent to the decibel level in a quiet conversation (about  49.5 Dba). It will help to offer a quieter environment than units with a higher noise output.

In addition, a portable unit that is easy to move is a simple fix for your office’s moisture levels, especially if you change locations or have a larger office space.

Some dehumidifiers are lightweight, and you can move them from one place to another without breaking a sweat. Similarly, heavyweight units with flexible casters and extendable top handles are also easy to move around.

The smart features and controls which make the specific dehumidifier a more user-friendly option for you are also important. So, be sure the unit is easy to operate and delivers the required results. 

Energy Efficiency

A dehumidifier that is energy-efficient will save you money and time in the future. Look for a unit with:

  • Humidity sensor: Units that feature a humidistat keep humidity levels in check. This will ensure your heating and cooling system runs effectively, reducing energy.
  • 24-hour timer: This means you can determine when the dehumidifier should run and when it should be off, which will help save energy. 
  • Frost sensors:  A dehumidifier operating in too cold temperatures is likely to frost up, thus reducing efficiency. Frost sensors prevent ice build-up by turning off the unit automatically to allow the ice to defrost. 
  • Energy star certification: These dehumidifiers consume less energy than standard models. On average, you would be reducing your energy usage by 15%.

Tank Capacity and Drainage System

The amount of water a dehumidifier can hold and what you need to do to drain it once full are important to saving you time, energy, and frustration down the road.

Some models have continuous drain capabilities. Others have detachable tanks to allow manual draining, while some sport both auto and manual drainage systems. But auto or continuous drain models are more convenient.  

They feature a drain hose that allows the collected water to flow freely from the tank. This saves you the trouble of having to empty the bucket yourself.

Dehumidifiers with an easy-to-use draining system are a gamechanger to save you time and energy.

Smart Features and Controls

Would you rather get a dehumidifier with automated controls or one you will have to operate manually? 

Dehumidifiers with humidistat allow you to control your room’s moisture levels effortlessly. The humidistat monitors and regulates the moisture levels in your room automatically to ensure your desired humidity levels are maintained. 

For instance, if you set the humidity levels on the control panel to 50%, the humidistat will signal the dehumidifier to turn off when it has reached 50%. If it goes below 50%, it will turn back on.

Other smart features that come in handy are a hygrometer detector, LED light indicator, power outage auto-restart, auto-defrost, auto-drain, and access to supported applications like Alexa and Google Assistant. 


Most manufacturers offer a one-year warranty for any workmanship and material defects only. Others may offer an extended warranty.

What To Know Before Buying Your Office Dehumidifier

An office dehumidifier is a big investment. So, you can’t afford to make the wrong choice.

Ensure you understand the difference between commercial, residential, and industrial dehumidifiers. Residential dehumidifiers are designed to manage humidity levels in small areas. While industrial and commercial dehumidifiers work better in larger spaces. And their humidity absorption rate is higher than that of residential dehumidifiers. However, your choice depends on your preferences and where you want to dehumidify.

Look beyond the dehumidifier’s price tag. Consider its maintenance, energy consumption, and any other lifetime costs that come with owning this unit.

Finally, think of your dehumidifier’s placement. Remember, these units rely on air movement to absorb excess moisture from your room, leaving the air much dryer. Thus, to get the most out of your unit, you will have to place it in a spot that allows for good air circulation. Any placement obstructing airflow into your space will significantly affect the dehumidifier’s efficiency.  

Using A Dehumidifier: What’s It Like?

We tested these dehumidifiers in damp, stuffy rooms that are prone to mold growth on the walls and ceiling. The dehumidifier should be placed on a flat, stable surface before plugging it into an outlet. After, you want to turn it on and set the humidity to your desired level; we opted for 40% humidity.

Turn the fan on to your desired speed—we chose high speed for maximum function—and set the timer. We set each one for 12 hours to test them during the day so we could monitor the changes in the room’s humidity.

If your dehumidifier has a drainage hose, connect it to the drain valve and put the drain hose into the floor drain. You can detach the hose once it’s empty and close up the drain valve, or you can permanently leave the drain hose in. This might be the best option if you plan to use your dehumidifier multiple times a week or more.

To ensure the unit works efficiently, we positioned it at the center of the room, at least 6 inches from any object that may obstruct air from flowing freely in and out of it. Be sure to close all the windows and doors to allow the dehumidifier to work its magic, absorbing the excess moisture from the air. It can’t work nearly as effectively if you have air flowing in and out from the windows.

Once the filter light highlights or starts flashing, this is a reminder that you need to clean the filter. To do this, turn the machine off, unplug it for safety, and move it to a more open space if you need to for cleaning.

You can clean the water reservoir with a liquid dishwashing detergent and a clean cloth. Be sure not to miss the bucket or air filters; Carefully remove them and wash them gently, rinse them, and then ensure they are completely dry before putting them back in the machine. You can opt for air drying, as it may be safest.

As the water tank and filters dry, consider vacuuming the machine to remove any dust and dirt from the grilles, and then wipe down the entire unit thoroughly. Again, be sure all parts are completely dry before putting the unit back together, and especially before plugging it back in for use to prevent any short-circuiting or problems with your dehumidifier unit.

Always read the manufacturer’s manual to understand the procedure to use and care for your specific unit.


Purchasing a dehumidifier is a big decision for your home, and you want to be sure you’re choosing the best that meets all of your particular needs. This can be tough, considering how many options are on the market.

After reading this guide, you now have a comprehensive picture of everything you should look for in a dehumidifier, some of the best options offered today, and how to properly care for your unit.

In order to be clear on your particular needs, start by listing the essential features you’re looking for in a dehumidifier and then rank them based on their importance. 

Be sure to look carefully at customer reviews and go for a 4 or 5-star dehumidifier that aligns with your specific criteria.
