The concept of having a basement is becoming more and more popular day by day. They exist in many homes across the United States and are used for various purposes.
Some people use unfinished basements for much-needed storage. Others finish their basements and add significant square footage to their living space. Some basements are used for offices while others are used as workshops.
While basements are great, they come with many challenges. Typically, it is much more difficult to maintain the moisture and air quality of basements.
The air in a basement is usually damper than the upper level. The temperature inside a basement is also much lower than the upper levels. In winters, the temperature in the basement can be several degrees lower than the temperature above.
It is difficult to dehumidify basements because most dehumidifiers do not work at lower temperatures. Later in this article, we will look at the five best commercial dehumidifiers for basements.
These commercial dehumidifiers are good for commercial sites. Many basements that are currently a job site also require dehumidification and so commercial dehumidifiers for basements are also used in job sites.
Moisture in Basements
Basements typically have more moisture than the upper levels due to many reasons. The first is that moisture seeps through the foundations. It can also enter through leaks and generally when there is moisture in the upper levels.
Job site basements also have excessive moisture because of the construction activities. It is extremely important to control moisture in job site basements as it will lead to weak foundations.
While high moisture levels in basements make them difficult to live in, you should worry more about the fact that it can cause molds to grow. Molds cause structural damage to the home and health issues.
A commercial dehumidifier can also be used for basements of residential homes. Basements usually have a large area and therefore commercial dehumidifiers are more suited for them as compared to household dehumidifiers.
A commercial dehumidifier can easily bring moisture levels in the basements below 50 percent. According to the Basement Health Association, humidity levels above 80 percent cause the growth of mold and mildew. However, a humidity level below 50% is ideal.
Signs of Excessive Moisture in The Basement
If you have a basement, you should have a commercial dehumidifier made for basements. However, you may not need not take action rapidly if signs of excessive moisture are not visible.
On the other hand, if these signs are visible, you should get to work as soon as possible. We have listed these signs below,
- Visible growth of mold
- You can feel the humidity in the wall when you touch them
- You can see condensed moisture on surfaces
- You smell a strange odor in basements
- Storage in the basements have a moldy smell
Top 5 Commercial Humidifiers: By Best Performing Feature
Guide to Select the Best Commercial Humidifier for Basement
Not all dehumidifiers are suitable to be used in basements. We have compiled a buying guide that will help you identify if the dehumidifier you have in mind can be used in the basements. Use this guide to help you make your purchase decision.
One of the most important features to look for in a dehumidifier is its drainage. While most fixed and duct dehumidifiers will come with a drainage system, it is not the same for portable dehumidifiers.
Dehumidifiers that do not have a drainage system cause inconvenience as you have to empty the tank manually. So, if that is something that you want to avoid, look for dehumidifiers that have drainage.
However, such a humidifier will typically cost more than the one that does not have a drainage system. So, if you are looking for more cost-effective options, you can ignore this.
It is important to know here that dehumidifiers that come with drainage systems are of two types. The first is using gravity and the second is using a pump. Again, the gravity one will be cheaper but less convenient than the one that uses a pump to drain water.
The capacity of the dehumidifiers should be sufficient enough to cover your whole basement. Job site basements are also typically much more in size as compared to other sites.
A good rule of thumb is 10 pints for every 500 square feet. So, if you have a 1500 square feet basement you should go for a dehumidifier with around 30 pints of capacity.
Here it is important to note that you may not use these figures exactly. Use these more ballpark figures and select the dehumidifier that has the nearest capacity to your calculations.
The capacity of the dehumidifier also depends on how damp your basement is. If you feel like your basement has severe moisture issues, feel free to use a dehumidifier that has a very high capacity.
Home basements are usually less damp than job site basements. So, if you are using a commercial dehumidifier for a job site, make sure that you get your hands on the one that has a very good capacity.
Basements usually span over the entire floor square footage of the house. So, typically they are larger than other rooms in the home. They are also damper than the upper floors. It is for this reason that we suggest commercial dehumidifiers for home basements also.
3. Automatic Defrost
If you live in a cold climate where temperature easily drops to sub-zero in winters, this is a must-have feature. As the name suggests, this feature automatically defrosts the ice that builds up in the dehumidifier so that running
4. Air filter
Some dehumidifiers come with air filters. They trap dust, pollens, and allergens and keep the air quality clean. They are good to have in a dehumidifier and improve the air quality significantly. These dehumidifiers are especially beneficial if you will be using them in your home’s basement.
5. Low-temperature operation
A dehumidifier that can easily perform in low operations has this feature. As the automatic defrost, this is a must-have if you live in a cold climate.
6. Automatic Humidistat
A humidistat works like a thermostat. Where a thermostat maintains a constant temperature in a room, a humidistat maintains constant humidity in the room. This feature eliminates the manual guesswork and the need to check the humidity in the basement manually.
Now that you have an idea about what your dehumidifier should have, let’s jump straight into our recommendations.
