Size or Capacity
You need to make sure that the dehumidifier has the appropriate moisture removal capability. It will be based on the size and dampness of your basement. For a damp area, a large capacity dehumidifier is better.
Dehumidifiers come in three different sizes based on their capacity. Small sizes are rated to remove 25 to 40 pints of moisture per day; Medium sizes remove 45 to 50 pints per day, and Large sizes remove 75 pints per day.
Here is the comparative review of dehumidifier based on the scale of the moist area:

- 40-60 pint dehumidifier for 500 sq. Ft. area
- 50-70 pint dehumidifier for 700-1000 sq. Ft. area
- 70-90 pint dehumidifier for 1500 sq. Ft. area
Portable dehumidifiers have a water tray which collects fluid that drips down from the coils. There is little chance that the reservoir will overflow and spill over if you forget to empty it. Because most of today’s dehumidifiers have an auto-shutdown feature, and some even have an indicator light to inform you the container is full.
Some dehumidifiers have what is referred to as a “continuous drain option.” It means that you can hook a hose up to the back of your unit and allow the water to drain directly out of your house. You can direct the hose pipe to a basement drain, a shower, a sink, a large bucket, or a sump hole. This option will ensure continuous moisture removal.
The noise of a dehumidifier can be very problematic, especially if the dehumidifier is in or near your bedroom. Dehumidifiers with two-speed fans run quietly at lower humidity levels.
They also save on energy costs. So it is a good idea to test a dehumidifier’s noise level before you make your purchase.
Without a built-in humidistat, getting the right level of humidity is very difficult. So it is wise to think about a dehumidifier with humidistat or built-in Hygrometer.
It will enable you to set the desired humidity level.
