What Is Relative Humidity?
Simply said, relative humidity (RH) is a measurement of the amount of water vapor in the air. It’s the amount of water vapor in the air represented as a percentage (percent RH) of the amount required to reach saturation at the same temperature.
High Humidity
As mentioned above, you measure relative humidity in percentage. Anything above 50% is too much moisture in the air. Excessive moisture and high humidity levels can create discomfort and health problems, as well as wreak havoc on a property.
Condensation can form on windows, toilet tanks, and pipes due to high humidity. When warm, wet air comes into touch with cool surfaces, the vapor in the air transforms into liquid water. This is what produces condensation.
Moisture traces can cause discoloration and mold growth on ceilings and walls. Excessive moisture can also cause peeling paint and creaky or bowing floorboards.
The cause of high humidity is usually due to the climate where you live, poor ventilation, and daily activities.
Low Humidity
Low humidity means that there is low moisture in the air. The air is dry and it causes poor health. It affects your sinuses and leaves them exposed to diseases and allergens. It makes it easy for viruses such as cold and flus to spread as well.
Low humidity is usually under 40% of relative humidity. This shows you that you need address the humidity issue. You can tell there is low humidity because your skin becomes dry and itchy, turns red, and is sore. You will also have itchy eyes. You will also have recurring headaches.
Your house will suffer too. There will be damage to your woodwork and furnishings due to low humidity. Shrinkage, hardwood floor separation and warping will be noticeable, as will your piano going out of tune, wallpaper peeling at the edges, drawers loosening, and molding gaps appearing.
Ideal Humidity
According to the Mayo Clinic, the ideal relative humidity for health and comfort is between 30 and 50 percent. This suggests that the air can hold between 30 and 50 percent of its maximal moisture capacity.
So when you have your dehumidifier and want to set it, you can set your ideal humidity between 30-50%. When it reaches the ideal humidity level, it usually switches off automatically. This helps not to go beyond and leave the air too dry.
