High RH Can Lead to Mold Growth and Health Problems

What is RH?

Relative Humidity (RH) is a measure of the amount of water vapor in the air compared to the maximum amount of water vapor the air can hold at a given temperature.

How High RH Impacts Indoor Air Quality

High RH levels create a favorable environment for mold growth, which can lead to respiratory problems, allergic reactions, and other health issues.

How to Measure RH

The best measure of moisture is a hygrometer, which measures the RH and temperature of the air.

Health Effects of High RH

• Respiratory problems, such as asthma and bronchitis
• Allergic reactions, such as sneezing, runny nose, and itchy eyes
• Headaches, fatigue, and difficulty concentrating

Water Damage and High RH

Water damage can significantly increase RH levels, leading to an increased risk of mold growth and health problems.

Preventing Mold Growth and Health Problems

• Maintain RH levels below 60% using dehumidifiers or air conditioners
• Address water leaks and other sources of moisture promptly
• Clean and repair humidifiers and air conditioners regularly
