Naturally, we’ll want to keep our indoors heated. But you don’t want to have an excess of humidity in the home. If you’re noticing condensation on the windows, this could be a sign that the inside of your home is too humid.

So how can you reduce indoor humidity during the winter? Be vehement about ventilating. On ArrowGroup.ca, it is explained that moisture can enter the air of our homes in many different ways. They include humidifiers, heating systems and even our house plants. In addition, our regular daily practices add moisture to the air. “Cooking three meals a day adds four or five pints of water to the air,” informs the site, “Each shower contributes 1/2 pint.”

As a result, it’s important to ventilate your home as best as you can. Use the exhaust fans above your stove when cooking and use the ones in your bathrooms while bathing. You may also want to crack the windows every so often. Now, considering the frigid outdoor temperatures, you’re not going to want to keep them open for very long. Instead, use the technique provided by ArrowGroup.ca.

“As a temporary solution to an acute problem, open a window in each room for just a few minutes,” recommends the site, “Opening windows allows the stale, humid air to escape, and fresh dry air to enter. After a shower, for example, open the bathroom window, or turn on the exhaust fan, so steam can go outside instead of remaining in the home.” You may also want to close the doors of the rooms where the windows are open so as to not make it too cold throughout the home.

Again, you don’t want to keep the windows open for very long. “Opening the windows slightly throughout the house for a brief time each day will go far toward allowing humid air to escape and drier air to enter,” ArrowGroup.ca further describes, “The heat loss will be minimal. Installation of storm windows will often relieve condensation on the prime house windows by keeping the interior glass warmer.”

On MadisonVinyl.com, Associated Press Building editor, David Bareuther reports that there are only three ways to reduce humidity. They are controlling sources of humidity, such as gas burners and clothes dryers, using dry heat to counterbalance all of the moisture produced by modern living and ventilating. Bareuther explains a bit further just how important winter ventilation is.

“Because outside air usually contains less water vapour, it will ‘dilute’ the humidity of inside air,” he notes, “This takes place automatically in older houses through constant infiltration of outside air.” If you’re still wondering about the ways in which you can prevent your home from being too humid this winter, it’s wide to consult a professional. That way, you’ll enjoy the very best indoor air quality.
