What Are Causes Of High Humidity In Basement  

Any an enclosed surrounding without ventilation is prone to high humidity settlement. As such, the basement is not exceptional. Water from rainfall enters the basement through the building foundation since it is sealed up. At night, cold air also goes inside, and that’s why you wake up in the morning to see humidness in your home basement. Apart from natural sources, drying clothes in your basement is another avenue (artificial way) how humidity finds itself inside. In a respite to the causes, it is almost impossible for humidity not to gain access into your basement, especially during the summer, but feasible to control the level for healthier living and home.

What Is The Recommended Humidity In Basement

While using a dehumidifier in your basement, it is good to know the best humidity level recommended by experts for this area. There is always a misconception if 70 percent humidity in the basement is good or 80 percent level. At the indoor, 60 % level is seen as the maximum comfort level for humans and belongings. The case is different in the underground environment as we hardly spent much time in this sphere. Therefore, researchers have opined that to control and avoid mold of all kinds, moisture smell, bacteria growth in the basement, keeping the gauge at 70 % is better than a higher level. This implies, 80 percent can trigger high humidity symptoms, and I know you don’t want that to happen. So your dehumidifier settings should be set accurately to figure 70 unless you have a model that comes with automatic humidity (hygrometer) regulator and controller  

Importance Of Dehumidifier In The Basement       

Early detection of moisture in the basement and installing a dehumidifier in your property can tackle the humidity menace. Problems such as mold growing on your floors, walls, ceilings, or other visible surfaces resolved dampness. Odor or mustiness is also an indication that you need a dehumidifier running in your basement. Overall, amidst wetness feeling on the entry your basement, the end solution is to dehumidify the space. There are different choice of dehumidifiers for the basement available in online stores where to find the right product to achieve a dehumidification process. 

How Do You Know What Size Dehumidifier To Buy

Basement dehumidifiers are different from your mainstream home dehumidifiers. Therefore, you need a specially designed dehumidifier suitable for this area since it is an enclosed space. There three things to note here such as:

  • Temperature level 

Your basement is generally cooler than your indoor living space because it’s underneath the ground. As such, the temperature level is extremely low. While a home dehumidifier can operate at 65+ degree temperatures, but such a unit cannot withstand the high humidity level below the ground. It implies that an ideal basement dehumidifier should have the capacity to operate at a lower temperature below 65 degrees. This requirement equals enhanced performance and effective removal of humidness. 

  • Automatic draining 

Since a basement is an area people live in, running a dehumidifier in there may be of great concern because you may need to empty its reservoir often. To avoid these challenges, you are to choose a product that can disperse the condensation collected by itself, and this feature is usually referred to in dehumidifiers as an automatic (continuous) drain option. Meanwhile, a little installation is required, whereby you need to connect a garden hose to the device and then extend into drainage or an appropriate where you want the water to be a dump.

  • Auto defrost 

This is a relevant feature to check for because basement humidity can go as high that you may least expect, resulting in moisture accumulating on the dehumidifier coil. The function of automatic defrost is to help remove any possible condensation that might build up in the coil, and this is done by the unit, without your knowledge. 

In addition to the above things to consider when choosing a dehumidifier for 600 sq ft basement is also an auto-restart function. Because you might not be chance walking into your basement all the time, when power is interrupted and restored, a restart function ensures the unit start working again with the previous settings not altered. 

While other advanced specs can be check as well, the features explained above are the most crucial aspect to determining the best basement (cellar) dehumidifier
