I received this question from one of our readers. She thought her windows had too much condensation on them. Here’s what I advised her.
During cold winters, your heating system can make the air in your home too dry, making it uncomfortable for you. To improve the air quality, you can add a humidifier to those areas where you spend the most time, or you can install a whole house humidifier to your heating system. To better monitor the humidity levels in your home, consider purchasing a hygrometer. A hygrometer is a small instrument with a display that shows what the relative humidity level is in the room where it is located. Inexpensive and user-friendly, this handy item can help you to monitor the air so you can adjust your humidity level when required.
Keeping in mind that every home is different, humidity levels can be affected by many factors. The number of people living in the home, the number of showers taken, the amount of laundry done and even a wood burning fireplace contributes to humidity levels if you keep firewood inside to dry out. The number of times a day an exterior door is opened and even cooking all affect your comfort level.
Keeping the correct humidity level in your home is important. Humidity levels below 25% are associated with increased discomfort, static electricity and dry skin, which can lead to chapping and irritation. High humidity levels can result in condensation within the home and on interior surfaces such as windows.
And remember, the colder it becomes outside, the easier it becomes for moisture to appear on your windows.
Warm air is drawn to cold air. The colder it is outside, the easier the warm air will migrate to a cold surface like your windows, and form condensation. So you most likely will have to turn the humidity level down. Monitoring the amount of condensation on your windows is as good a way as any to gauge and adjust the humidity level in your home.
The recommended average relative humidity level is between 35% and 45%. This range will provide the best comfort for your family, while helping to protect wooden furniture and floors and many other belongings or materials in your home.
Hope this helps,
