What do I need to consider when shopping for a crawl space dehumidifier?

When shopping for your crawl space dehumidifier, the first thing you need to consider is the change in air and humidity levels ever hour. The humidity level of your air space is not consistent throughout the day, and the air is constantly changing as the day gets first hotter and then cools off.

If your crawl space is extremely wet, you will see water pooling on the floor of your crawl space. This means that you should obtain a crawl space dehumidifier that handles 6 air changes every hour.

If you have a moderately wet crawl space, you will be able to see water leaking. You may also be able to see mildew or mold growing visibly in your crawl space, and your crawl space dehumidifier will have to handle 5 changes of air every hour.

If your crawl space always feels moist or damp, regardless of the weather conditions, then you can consider it a very damp crawl space that needs 4 changes of air every hour.

A moderately damp crawl space only feels damp and smells a bit musty in weather that is humid, and your crawl space dehumidifier will need to handle 3 changes of air every hour.

You also need to find a crawl space dehumidifier that can handle the volume of air in your crawl space. You should measure the cubic feet of your crawl space in order to let you know what the total volume of air your crawl space dehumidifier will have to handle. Simply multiply the width of your crawl space times its length times its height, and the answer will be the cubic feet of your crawl space.

The crawl space dehumidifier will need to move a certain number of cubic feet of air in your crawl space every minute in order to effectively dehumidify your crawl space. In order to ensure that the moisture is effectively removed, your crawl space dehumidifier needs to handle a certain number of cubic feet of air per minute. If you get a crawl space dehumidifier that cannot handle enough air per minute, it will constantly be running and will break much faster.

In order to determine the proper cubic feet of air to be moved per minute by your crawl space dehumidifier, you need to multiply the cubic feet of your crawl space by the number changes in the air. Then divide that number by sixty in order to determine how many cubic feet of air will need to be handled every minute. For example:

Your crawl space is 2000 cubic feet, and requires 3 air changes = 6,000
6,000 divided by 60 = 100 cubic feet of air per minute must be handled by your crawl space dehumidifier

Ensuring that your crawl space dehumidifier is able to move enough air will help to keep your crawl space from being overly moist and the mildew and mold from growing.


You should also look for a crawl space dehumidifier than can remove enough moisture from the air, and that amount if measured in pints per day. A small crawl space may need as little as 10 pints per day removed in a fairly dry climate, but a large crawl space that is very wet can require as much as 50 or more pints per day removed. The number of pints per day to be removed depends upon the location of your house, the climate in which you live, and your daily habits.

Once you have figured out all of the above details, you want to look for a crawl space dehumidifier that drains instead of simply running into a drain pan. This will make the task of disposing the water easier, as the crawl space dehumidifier will simply be connected to your plumbing system. Also, make sure that your crawl space dehumidifier is energy conserving, and that it can operate in any temperature.

Do the right thing for your house and purchase a crawl space dehumidifier to help keep both you, your home and especially your family healthy!
