Indoor Home humidity is the amount of moisture that can be found in the air. Home humidity levels are measured in percentages and can usually be controlled with an addition of a whole house humidifier, a home dehumidifier or space humidifiers place around your house. The effects of indoor humidity usually leaves some tell tail signs around the house and will let you know if your home humidity level is too high or too low.
If you have a high indoor home humidity level then you may find mold and bacterial growing in your walls. I have even noticed black lines on walls where the drywall attached to the studs. This happened in the winter where the studs actually had condensation on them from the high indoor home humidity levels. Another sign of indoor humidity levels that are too high are bands of moisture forming on your windows in the winter time. Your windows should never have a band of moisture that is more than a half-inch around the panes of your window. If you do then your home humidity level is probably too high. High home humidity levels can us usually be resolved with the use of a home dehumidifier or eliminating the cause of moisture entering your home.
Some signs that your home humidity levels may be low can consist of nosebleeds, high levels of static electricity, shrinking or cracking of wood flooring or moldings and that dry scratchy throat or sinus passages that causes you to wake up during the night. Low home humidity levels can be increased through the use of a whole house humidifier, a furnace humidifier, or regular humidifiers that you place around your home. Because heating system during the winter can cause low home humidity, the cure is to add some moisture into the air. It is important to keep in mind good humidifier use and care practices, because an uncared for humidifier can cause more harm than good.
