Tips on Choosing The Best Dehumidifier For Your Home’s Crawl Space


House owners with crawl spaces often don’t realize that these completely enclosed areas are breeding grounds for molds and mildews. They rarely receive any fresh air and sunlight which makes these places high in moisture. The air is constantly drawn up into the house from the crawl space sucking up mold spores into the house. The dampness can also damage the wooden flooring. Justin Williams, founder of The Dehumidifier Experts stated in an article that it is necessary to invest some money in buying a good crawl space dehumidifier.

Here are some tips that can help you choose a good quality crawl space dehumidifier to keep this area moisture-free.

The first thing that you should do before buying a crawl space dehumidifier is check the humidity level. The humidity level can range from moderately damp when the area smells musty and damp to extremely wet when you notice standing water. The wetter the area, the more air changes will be required to keep the humidity level low. If you notice any standing water or water leaks, the appropriate thing to do would be to fix the problem that is leading to the presence of excessive water. Once the problem has been tackled, you can test the humidity level of the crawl space using a hygrometer and buy a dehumidifier keeping in mind the moisture level in the area.

The air changes required per hour will depend on how wet your crawl space is. Depending on whether it is moderately damp, very damp, wet, or extremely wet, the air changes can range from three per hour to six per hour.

The cubic feet of the crawl space is another factor that will determine how powerful the crawl space dehumidifier needs to be. Multiply height by width by length to give you this measurement

The airflow is the cubic feet of air that needs to move per minute to keep the humidity levels in the area at the lowest. You should buy a dehumidifier that can create the right cubic feet per minute of air flow or CFM to remove the moisture from the crawl space. The CFM depends on the cubic feet of the area and the number of air changes that are required.

Depending on the climate of the area that your house is located in and the dampness in the crawl space, you will also need to find the number of pints of water per day that must be removed from the area to dehumidify it. A moderately damp space will require a crawl space dehumidifier that does not require removing a high number of pints of water per day whereas for an extremely wet area, you will need to buy a dehumidifier that is able to remove a higher number of litres of water per day.

You also need to make sure that the crawl space dehumidifier fits into space, it has an automatic drain option and is also energy efficient.

A crawl space dehumidifier can prove to be a good investment since the air from the area is constantly entering your house. If the air in the crawl space is dehumidified, it will ensure that it is free of dust mites and molds and mildews, thereby improving the quality of air that is being sucked up into your house from this area.
