And if you are limited on space, make sure the dehumidifier doesn't take up too much room. Some units are larger than others, so pick the one that is best suited for your needs.

Volume per CMH

CMH stands for cubic meters per hour and is a way to measure the amount of moisture any dehumidifier can remove from the air. You need to consider the volume per CMH of the dehumidifier.

Noise

All dehumidifiers come with a noise rating, so be sure to check it before you buy.

Capacity range

Aesthetic
