Choosing the best basement dehumidifier might be a hassle if accuracy with measurements isn't kept.  However, it is also important to pick the correct humidifier as models with the same design can differ in their capacity. 

For a 500 square feet space, you may need a unit with a capacity 10-pint capacity dehumidifier. It is easier to calculate how big of a dehumidifier you need this way. Just add four pints for every 500 Sq.Ft. 

The pints and size will vary depending on how damp a place is. For a normally humid area, you're going to need a 14-pint dehumidifier for 1000 Sq ft. For a place with high a humidity level, it is advisable to use 12 pints as a base for every 500 square feet.

It is important to place it somewhere that has maximum humidity. There can be many different places where the dampness comes from, such as an exhaust pipe, the door or cracks. 

Placing the dehumidifier near the source will help stabilize humidity levels before it can cause damage. The size of the space is crucial because if the source is big enough, the dehumidifier will have to be kept in the center. It is also best to ensure that there is nothing blocking airflow to the unit.

If you place it in the right spot, health benefits are guaranteed as well. It provides an effective solution to moisture problems like mildew and mold spores.

This means a stronger immune system down the road as well.

Basements, crawl spaces and underground environments are naturally damp. Moisture can be good in certain conditions in arid places, but if a high humidity level prevails in an enclosed space for too long, it will cause damage.

The most common damage that rots away foundations and makes your house hollow and rotten from the inside out is mildew or mold spores. This fungus can cause a putrid basement smell as well. 

It is due to these reasons that keeping a dehumidifier in basement areas will keep the air dry. With dryer air, your air conditioner will work more efficiently as well.
