Underground areas are dark and dusty and the air quality isn’t always the best. If humidity levels rise in an airtight underground (which they often do), excess moisture can lead to mold, mildew, rot and other problems.
The best commercial dehumidifier is your solution to prevent the growth of mold and bacteria. The machine hangs from floor beams in the underground, drawing in moist air, removing moisture and returning fresh, dry air back. If your crawl space is wet, read on to find out more.
No one wants mold or mildew to grow under their feet, and the best basement dehumidifier can help prevent that. While these dehumidifiers work very similarly to indoor and basement units, there are some differences and points to consider when purchasing. The following sections will cover the main considerations to be taken into account.
Choosing the right size dryer is critical to making sure it does the job. If it is too small, it will not be able to remove moisture from the entire underground. If it is too big, it consumes more power than necessary and the initial cost is too high. There are several things to consider.
A humidifier is an important feature to look for in the best underfloor dehumidifiers. They allow the user to set the level of humidity that the dehumidifier maintains. The device will work when the humidity level exceeds the set value and turn off when it falls below the set value. Why are they important? Consider the following points:
Underground spaces are popular in many parts of the country, many of which are very cold in winter. Exposing the underfloor dryer to air can freeze the condenser coils and damage the machine. Therefore, a defrost system is necessary.
The defrost system maintains a higher temperature inside the dehumidifier. This prevents condensate or coils from freezing with cold air, allowing the unit to run longer. This can be an important feature even in regions where frost is unlikely. In fact, freezing is only required once to break the coil.
Like home dehumidifiers, basement dehumidifiers collect moisture that is removed from the air. Unlike home models, it is not possible or practical to go underground twice a day to remove the tank. Instead, these models drain water, but some models or scenes require a condensate pump to operate effectively.
The unit, equipped with a condensate pump, sends water to where it needs to be. Whether it’s through a long hose or a drain that can only be accessed above the unit, the condensate pump pushes the collected water out of the underground so you don’t have to crawl underneath and empty the tank.
A typical home dehumidifier makes a noise similar to the hum of a window air conditioner, and the higher the power, the louder the device will be. The noise level of most small dehumidifiers ranges from 30 decibels (the equivalent of normal conversation) to 45 decibels (the equivalent of a refrigerator hum), but manufacturers are not required to list noise levels on their devices.
Reading customer reviews is the best way to determine the noise level of a particular dehumidifier. However, keep in mind that placing the unit on a level and soft surface will also help reduce noise levels.
A dehumidifier can provide a constant supply of fresh and dry air to the underground, resulting in an energy efficient solution that improves air quality and prevents mold growth throughout the season. Small basement dehumidifiers can run from 280 to 300 watts, which means they will use 4 to 5 cents of electricity per hour. This is equivalent to about $150 a year if your dehumidifier runs 9-10 hours a day.
However, an Energy Star rated dehumidifier uses about 15 percent less energy than conventional devices. In the long run, this means savings of around $175 over the lifetime of the dryer, not to mention avoiding significant greenhouse gas emissions.
There are several other features that can make a particular model the best crawling dehumidifier for your needs.
Before choosing a dehumidifier, it is important to measure the space to find out which model works best. It should also be placed where there are no airflow obstructions and minimum noise levels. Because some dehumidifiers also require drainage, your model should be placed as easily accessible as possible.
While some models can be installed without professional help, some models that require connection to an HVAC system may require installation by a contractor. If you choose to install it yourself, you may need a drill or screwdriver, a hammer and nails, metal tape and PVC and/or rubber tubing, depending on the model you choose.
There are many decisions between choosing the right size, needing a pump, and choosing handy options like remote controls and filters. The following list is intended to simplify the buying process as it is a selection of some of the best dehumidifiers on the market.

Even with extensive experience in choosing the best dehumidifier for your basement, additional questions may arise. This section is intended to provide answers to some of the most frequently asked questions about Underground Dehumidifiers.
Technically, you can, but they are not built for the harsh environment. Conventional dehumidifier coils are short lived, rarely have a defrost function, and most have a water tank that needs to be emptied. In addition, dust in the underground will definitely shorten the life of the indoor unit.
Since the underground can be very wet, it is recommended to use a dehumidifier of 50 liters or more for adequate drying.
You must adjust the dehumidifier not for temperature, but for humidity. Generally, you want a room with humidity below 55%, so setting the units to 50% is fine.
You need to install the dehumidifier in a place where it can freely suck in moist air and exhaust dry air. It is best to install it in the center of the underground.
The average dehumidifier will reduce the humidity in the basement within 8-10 hours, depending on the size of the room and the current level of humidity.
Cleaning your dehumidifier should be relatively easy, with most parts simply wiped down with a damp cloth. Lime scale can build up in tanks, which can usually be removed with white vinegar or lemon juice. Air filters usually require a quick monthly flush. To ensure the longevity of the machine, be sure to follow the manufacturer’s instructions.
The dehumidifier does not require much maintenance other than cleaning or replacing the filter every 6-12 months. With proper maintenance, your dehumidifier can last about 5 years.
