One Way to Control Mould Growth
There are many ways to control or prevent mould growth in a building.
Monitoring and managing your building environment is critical to a healthy home.
Mould or Fungi require food and a water source. If you reduce one or both, you reduce the risk of mould growth.
So how do you manage mould growth by reducing food or water?
This article focuses on an aspect of water. Water can be in the form of humidity. More specifically, “relative humidity” which is humidity relative to temperature.
It’s the amount of water in the air. Controlling this will help reduce the risks of mould growth and other biological pollutants and contaminants.
There is an optimum relative humidity (RH) level of 40% to 60%
Keeping within this optimal zone is critical.
Relative Humidity will always equalise or balance out, so if you open windows and doors, it will equalise with the outdoors.
When going to sleep, the Relative Humidity in a bedroom will increase as we will release water vapours from our breathing, and in an enclosed room, it will increase the Relative Humidity.
Measure the Relative Humidity in living and sleeping areas to get an idea of what the levels are during different times of the day or night.
There are different strategies that can be taken to manage relative humidity, but first things first, measure and monitor.
Purchase a hygrometer or an indoor air quality sensor such as the uHoo to monitor 24×7.
