Final answer:
The four general measures to prevent moisture intrusion include preventing water intrusion, controlling humidity, sealing air leaks, and providing ways for moisture to escape. Humidity control can help maintain proper indoor air quality and decrease the risk of indoor air pollutants related to moisture, such as mold.
Step-by-step explanation:
Four general things you can do to prevent moisture intrusion are: Prevent water intrusion, Control humidity, Seal air leaks, and Provide an escape for moisture. Preventing water intrusion involves ensuring that the building envelope is intact and waterproof. Controlling humidity is essential for maintaining indoor air quality and can be achieved by keeping indoor humidity levels between 30 and 50 percent.
Sealing air leaks helps to prevent moist outside air from entering and condensation from forming. Finally, providing an escape for moisture means allowing indoor moisture to vent to the outside, avoiding accumulation that can lead to mold and other issues.
To control humidity, you may use tools like a humidity gauge to monitor levels and use a vaporizer or humidifier to increase humidity, or open windows and use air conditioning to decrease it. High humidity can increase the risk of mold and can affect indoor air pollutants.
Conversely, increasing humidity can lead to reduced evaporation rates, which impacts various environmental and biological processes.
