If you are in the need of removing great amounts of excess moisture from the air in larger spaces like e.g an office complex, construction site, large basement, storage area, etc then getting a commercial dehumidifier is the best solution for the problem. As these areas usually aren’t properly ventilated it gives mold and mildew a chance to form which could cause health related issues for those who are exposed to it, as well as it can cause serious damage to the ceiling tiles, walls, furniture, etc. A good commercial / industrial dehumidifier will be able to keep the humidity-level low in these areas and the air safe for breathing at all time.
To make it easier for you to find the Best Commercial Dehumidifiers For Basements in 2021, we’ve spent a lot of time doing research, comparing features, reviewing performances and reading buyers reviews. We’ve also made a short buying guide for commercial dehumidifiers to give you a better idea of what to look for when buying a dehumidifier for larger spaces.
Why Choose a Commercial Grade Dehumidifier?
As you probably already would have guessed, commercial / industrial / or “heavy-duty” dehumidifiers are made for being able to remove high amounts of excess moisture from larger spaces like for instance a large basement. What separates a commercial dehumidifier from a residential dehumidifier is that it can usually reach up to greater distances which makes it the best choice for larger structures, and it has the ability to handle humidity levels up to about 95%, while a residential dehumidifier typically “only” can handle up to 75%. This makes the commercial dehumidifier a great option if you’ve got a source of “standing water” / flood in your space. They are also usually more “rugged” in construction and will make a bit more noise whilst operating as they’re more powerful than the residential unit’s.
Whether you need to remove excess moisture in the air from office buildings, larger basements, storage areas / warehouse, marine environments, spa and indoor pool environments, etc, commercial dehumidifiers will be able to operate successfully even in extreme temperatures and in difficult weather conditions.
How Do You Know if You Need a Dehumidifier?
Maintaining a proper level of humidity is important for health reasons, as well as keeping ceiling tiles, walls and furniture safe from being damaged. These are the typical signs that you need a dehumidifier:
Odors – High levels of humidity over time will lead to musty smells and unusual odors
Condensation / Frost Build-up – Condensation and frost/ice tends to be seen on cold surfaces like windows and doors
Water Stain Marks– Water stains that can be noticed on drywall, floors or anywhere else is a strong indicator of excess humidity
Visible Rot, Mold Spots and Cracking Paint – Ceilings, walls and other areas being exposed to excess moisture may lead to the growth of mold and mildew. Mold will typically first appear as small dark spots (black, brown, green). Changes in the wood structure and/or color indicates the presence of rot and give reasons to believe that the humidity level have been a lot higher than it should have been for a long period of time. Cracking paint / peeling is also a typical sign that the level of humidity needs to be lowered
Allergy Reactions and Respiratory Issues – Being exposed to high levels of humid air can lead to common respiratory / allergy reactions like having difficulty breathing properly, stuffy nose, watery/itchy eyes, rashes on skin and other irritations.
To make sure that there is a higher level of humidity in your space, you could measure the level with a hygrometer. This device that resembles a thermometer is helpful in keeping control of the humidity level at any time. Generally, the humidity level in basements should be from 30 – 55%. Amazon has a selection of inexpensive hygrometers more than capable of accurate measurement.
What to Look For When Buying a Commercial Dehumidifier?
When choosing a “commercial” dehumidifier there are a lot of factors to take into consideration when determining what’s the best commercial dehumidifier for your space. Some of these functions and features may be more important for you than others, depending on where you’re planning using it.
Coverage Area – The coverage capacity of a commercial dehumidifier is a very important factor that you need to keep in mind when finding the optimal unit for your space. The coverage area / coverage capacity of a device is the amount of space your commercial dehumidifier will be able to operate and remove humidity in successfully. You’ll also need to take the condition of the room (wet / dry) into consideration before deciding what unit to buy. This article will give you a better idea of what will be the best choice for your space and condition
Low Temperature Operation – Most industrial / commercial dehumidifiers will be able to operate in lower temperatures. However, you should look for the specified operating temperature range issued by the manufacturer to make sure that it meets your needs
Build Quality – Most commercial dehumidifiers are usually made of steel or heavy-duty plastic which makes them much more durable than the residential dehumidifiers that are usually made of lightweight plastic materials
Pint Capacity – The capacity of a dehumidifier is rated in pints of moisture that is removed per day (24 hours). The pint capacity for commercial dehumidifiers is typically 70 pints or more
Drainage / Built-in Pump – Automatic drainage is one of the most important features for most as it allows you to run the dehumidifier continuously instead of having to think about emptying a collection tank manually several times a week during operation. By connecting a drain hose to the unit you’ll be able to conveniently use the nearest floor-level drain. Some unit’s come with a built-in pump which allows for the water to be pumped vertically and horizontally to the closest drain
Auto Restart – In case of interruption or a power failure, most dehumidifiers comes equipped with an auto restart function that will return the dehumidifier to operation once the power is restored
Built-in Humidistat – The best dehumidifiers on the market come with a built-in humidistat that will allow you to set the desired level of humidity. Some unit’s will shut off automatically when the desired humidity level is reached and then turn itself back on if necessary
Noise Level – In general, commercial dehumidifiers will be more noisy than residential dehumidifiers. You should make sure to check the noise level issued by the manufacturer or check out user reviews to get an indication of how loud the unit operates
Frost sensor / Auto Defrost – A frost sensor will detect frost buildup and allow you to operate the dehumidifier without you having to worry about frost damage
Portability – Some model’s comes equipped with handles and wheels which allows you to easily place them wherever you want
Energy Consumption– Some commercial dehumidifiers will be more energy efficient than others and they will help you save some money on your electricity bill. You should look for Energy Star-labelled dehumidifiers as they can save you as much as up to 30 percent on energy consumption
Warranty – You should make sure that you have read and understood the warranty agreement before making the decision to purchase a dehumidifier as some warranties only cover parts of the product. Having a reliable warranty is always good if an issue where to arise
As you’ll probably be reading some of these reviews, you’ll notice that there are some terms and abbreviations that you might not be familiar with. Below, is a short explanation for some of these terms and acronyms.
Saturation rating – This rating is taken in extreme environments of 90 degrees Fahrenheit and at 90 percent humidity and represent the absolute maximum of what amount of moisture the unit is able to remove in a day in such conditions.
AHAM – Association of Home Appliance Manufacturers. The AHAM-number is the amount of moisture a dehumidifier is able to remove per day at standard testing conditions of 80 degrees Fahrenheit and at 60% humidity. This number is measured in Pints Per Day (PPD) and is usually a more relevant statistic than the saturation number,which is why we use only the AHAM-number in our reviews.
COP – Means high coefficient of performance and indicates the effectiveness of a dehumidifier, listed in litres of water extracted per kilowatt hour (kWh) of electricity used.
RH – Means the relative humidity and is the amount of water vapour that is present in the air at a given temperature and it is expressed as a percentage.
Humidistat – Is an instrument made to control and indicate the RH-level in the air. Most dehumidifiers features a built-in humidistat.
GPP – Stands for grains per pound,and is a measure of the weight of the water in the air.
HGV – Stands for hot gas valve and is a defrosting system used in dehumidifiers.

Frequently Asked Questions (FAQ) about Commercial Dehumidifiers
Who Are Commercial / Industrial / Heavy Duty Dehumidifiers For?
Commercial / Industrial / “Heavy duty” dehumidifiers are made for removing excess moisture and maintaining the humidity level in larger spaces, which makes it a great choice for businesses and commercial settings.
Can I Use a Commercial Dehumidifier in My Home?
The answer to this question is yes, you certainly can use a commercial in your home. The humidistat that is featured will make sure that the desired level of humidity is maintained in your house. However, you should be aware that a commercial / industrial dehumidifier will make a bit more noise than a residential dehumidifier, and they are a bit more bulky and not as visually appealing as the residential unit’s.
What Humidity Level is Optimal in a Storage Area, in a Supermarket / Warehouse and in other Commercial Areas ?
In our opinion, the humidity level should be maintained below 55% to prevent dust mites, mold and mildew from growing. The ideal humidity level is from around 40-50%. If, your commercial space has water damage you might need to go lower than 40%. The humidity level should not go under 30% as this can lead to splits and cracks in furnitures and wood floors, and cause an increase in respiratory viruses as low level humidity levels allows these germs to thrive.
How Much Water Will a Commercial / Industrial Dehumidifier Be Able to Remove in a Day?

Make sure that you choose the right dehumidifier for how much moisture that -needs- to be removed, and how quickly you want it removed.
How Long Does it Take to Get the Humidity to the Desired Level?

Where Should I Place my Dehumidifier?
The dehumidifier should be placed in the most humid room for the best effect. There should also be some space around the unit for it to work optimal and you should ensure that the air inlet and outlet will not be blocked. Another important thing to keep in mind is that it should not be placed near sources that will create any dirt and dust, like woodworking equipment, etc.
