Alteration in the normal relative humidity of a home isnít good for anybody or anything. This means if it is too high or too low, it could be bad for you, your family and your home.
Too low humidity allows a person to manifest various types of respiratory illnesses. It can also cause drying of other parts of the body and could lead to feeling of coldness despite having a warm environment. Houses with too low humidity may also have structural problems as wood can shrink in this condition.
Too high humidity is the perfect condition for the growth of molds, mildew and bacteria. This is because air at this time would undergo condensation. As a result, certain areas of the house become damped, which then provides microorganisms the perfect environment for growing.
If you are starting to experience structural problems for your home, at the same time experiencing health problems, there may be something wrong with your humidity. Hence, you should learn to identify events that would call for the use of humidifiers or dehumidifiers.
Difference between Humidifiers and Dehumidifiers
Humidifiers and de-humidifiers are appliances built to help you increase or decrease humidity levels. Since human activities and climate change can result to high or low humidity, you might have to buy one to be able to control it and normalize its levels.
Humidifiers work to increase humidity for a room or the whole house. There are basically two types: the warm mist and the cool mist. The former works by boiling the water to produce steam that will be sprayed in the room. This kind of humidifier is usually for point of use purposes. On the other hand, cool mist work by using allowing cold water to be absorbed by a wick. The wick allows water to evaporate with the use of a fan resulting to increase of humidity. Humidifiers now have other types like the impeller and the ultrasonic waves.
Dehumidifiers work the opposite. This removes humidity by collecting your indoor air. Inside, it passes through the cooled coils and condenses air to remove the moisture. After that, air will be reheated and be brought back inside the living space.
Determining the Right Device Accurately
The only way to accurately identify which type of appliance to get is to determine the relative humidity in your home. The concept is so vague to explain but basically it speaks of the amount of moisture that air contains in a given temperature. To be able to know which is acceptable, certain standards have been set by United States Environmental Protection Agency to determine the normal ranges for indoor relative humidity.
But how do you know your indoor relative humidity? Yes, there are signs and other adverse effects of too low and too high indoor humidity; however, for a more accurate identification you may need to buy a device called hygrometer.
This device has two types: electronic and mechanical. But here's the catch: not all parts have same humidity levels. The best way to get an accurate reading is to put the device in the area where most of the signs of low or high humidity are visible or where humidity is most felt.
Once in place, it will show the percentage of your relative humidity. In general, the normal range falls between 30 to 50 percent. If it falls below the lowest range, you may need a humidifier. Otherwise, falling above the normal range makes dehumidifier more appropriate.
