The definition of humidity is the amount of water vapor in the air. A humidity level of 67 is considered high, as it is above the ideal range of 30-50%. High humidity can cause a number of issues, such as discomfort, increased risk of mold and mildew growth, and difficulty breathing. In addition, high humidity can cause condensation on windows and other surfaces, which can lead to water damage. To reduce the humidity level in your home, you can use a dehumidifier or air conditioner to remove excess moisture from the air. You can also use fans to help circulate the air and reduce humidity. Taking these steps can help keep your home comfortable and reduce the risk of damage caused by high humidity.
