Too Much Moisture: Dehumidify
In general, summer is the season of high humidity. If you have an air conditioning unit, this already provides dehumidification as part of its process. But if you have high humidity even when it’s not hot, or if you don’t want an air conditioner but still need dehumidification you can use a dehumidifier.
There are two main types of dehumidifier: refrigerant and desiccant. Refrigerant dehumidifiers use the same technology that air conditioners use, while desiccant dehumidifiers absorb moisture from the air. Since refrigerant dehumidifiers are typically used for homes, you will probably need this type.
Too Dry: Humidify
Dry air is often associated with colder weather, but some climates are dry year-round. Regardless of where you are, dry indoor air is a problem that can be solved with a humidifier.
If you want more individual control, a small humidifier that emits moisture into a room will allow your moisture-prone areas to stay dry while creating the correct humidity levels elsewhere. This is a great option for bedrooms that get too dry.
