eli5 how do dehumidifiers work?

A fan draws the humid air in, where it’s directed toward either a cooled coil (which causes condensation that is collected in a reservoir) or a desiccant (like silica gel, which ~~absorbs~~ adsorbs moisture). For the former, the air is then warmed back up again before another fan expels it back out into the environment.
