When you think about it, what really gets to people on those exceptionally hot days in the summer is not so much the heat as the humidity. Too much humidity in the air just makes you feel bogged down and tired, not to mention completely uncomfortable. That's why humidity control is such an important factor in keeping cool and comfortable during the warmer months of summer.

On the opposite end of the spectrum, too little humidity can also be a problem. During the winter when we turn on our heaters, a lot of the humidity in the air in our homes disappears creating an equally uncomfortable dryness. So obviously, controlling the humidity is key to staying comfy. According to the United States EPA, maintaining a level between 30% and 60% humidity is optimal for staying comfortable in any season.

When you need more than just air conditioning humidity control: the dehumidifier

While air conditioners and heaters can play the role of a humidity controller, in order to really fine the level of humidity in an area, a humidifier or dehumidifier is needed. Dehumidifiers work on the same basic scientific process that air conditioners work on – both devices uses evaporator and condenser coils to affect the air that passes through them. However, dehumidifiers are actually placed indoors (unlike air conditioners which are usually outside), and the setup of the coils is different with the end result being the production of warm but humidity-free air.

You can use a dehumidifier to supplement the standard air conditioning humidity control, or you can just use a dehumidifier separately. These devices can also have more specific purposes, such as using them in a damp, cold area that is prone to developing mold. They aren't always the best option for cooling purposes, because they produce warm instead of cold air. However, in extremely humid climates a dehumidifier can still be a way to get a little comfort on an oppressively hot day.

Another type of humidity controller: the humidifier

The other main type of humidity controller is the humidifier. There are many different styles of humidifiers, but they all ultimately work to help increase the amount of moisture in the air. Some units are built simply to increase humidity in one room, while others act as part of an air conditioner humidity control suite and can affect the humidity in every room in a home. A humidifier is a good choice for extremely arid climates that are uncomfortably dry. Be aware, however, that too much humidity can lead to an increase in dust mites as well as a greater risk of mold, both of which can be very unhealthy. Also, oftentimes a lot of dust and other small debris end up being sent through the air by a humidifier, and this can be unhealthy.

Remember that you want to try and keep the humidity level in your home somewhere between 30% and 60%, so you should use humidifiers and dehumidifiers carefully. Most air conditioners are already set up to keep humidity within this level, so most of the time additional humidity control devices aren't really needed.
