Excess humidity in the crawl space causes:
- The growth of mildew and mold – moist surfaces of the crawl space are the perfect place for mold and mildew to grow.
- Dampness and odor in the crawl space - Most crawl spaces lack enough ventilation to allow good circulation of air, the air smells damp. If this air is not cleaned it could spread the odor into the house.

- If you cannot access a hygrometer, you can carry out a simple inspection of your crawl space.
The levels of humidity can be classified into:
- Moderately damp – Feels damp and smells musty during the humid weather months.

How to select a crawl space dehumidifier for your home?
Today there are so many brands of crawl space dehumidifiers in the market it can feel overwhelming for many homeowners to choose the right one. Once you have determined the level of humidity in the crawl space you need to measure the size the crawl space (in cubic feet).
With this information, you can easily determine the capacity and air flow requirement the crawlspace dehumidifier should have.
- The air flow of a crawl space dehumidifier - This refers to the cubic feet of air the dehumidifier is dehumidified per minute. The air change per hour (ACH) refers the number of times the air is cycled through the dehumidifier per hour. Crawl space with high humidity will require a dehumidifier with a higher ACH.
Moderately damp (60 – 70%)

How does a dehumidifier work?
Dehumidifiers are electric appliances that extract excess humidity from the air.
We designed our dehumidifiers to pull the air from the house into the unit where it then passes over a series of coolant coils that condense the excess moisture. This removes odor, mold spores, and other impurities from the air. The unit then collects condensed water in a collection tray or pumped out of the unit depending on the model of BaseAire dehumidifier you buy.
The air is then warmed up and pumped out of the dehumidifier back into the room. This process repeats until the relative humidity level of the space lowers below the set level.
