So how do I control the humidity in my home?
The best way to control humidity is by extracting it from the source. Always use your range hood when cooking and your bath fans when bathing or showering, at minimum. Keep in mind when you are exhausting air from your home, this air should be replaced, or your home may go into negative pressure. When air leaves without being replaced this may result in doors to the home being harder to open, and to slam shut when you are closing them, but the big danger is when you have natural venting gas appliances. Your hot water tank, your furnace, or your fireplace may start dumping CO into your home as a direct result of negative pressure.
In order to minimize the chance of a negative pressure situation you must replace the air being exhausted. In mild climates this may be accomplished by keeping a window slightly open in the area where the fan is running. In colder climates, or just during cold winter months this is not recommended as your heating system will have to work harder, and it would create quite a draft in your home, so the solution is to install an ERV or HRV system into your home.
