By this time next week, we will all be able to say that wintertime is over. Or will we? We Canadians know better. The calendar may indicate the beginning of spring next Monday, but we understand that when frigid temperatures persist and there’s still snow on the ground – it is still winter. As a result, the time for opening our windows to let the fresh air come inside is still several weeks away. Here’s the thing though – it shouldn’t be.

In fact, it’s recommended that we all keep our windows open all winter long. No, we’re not saying that your windows should remain open all the time. Instead, we’re saying that it’s wise to let the fresh air from outside circulate with the stagnant air from inside for, at least, a few minutes every day – no matter how cold it is. The reason for this, quite obviously, is to promote ventilation. And ventilation in your home is incredibly important.

Here are three reasons why:

1. Ventilation helps to lower VOC concentrations. Our homes are filled with harmful VOCs. Volatile organic compounds are found in many of our household cleaning products, furnishings, paints and carpets. If you can smell the scents that emanate from these household items, you can pretty much guarantee that you’re in the presence of VOCs. In high concentrations, VOCs are toxic.

However, as Dustin DeTorres explains on ZehnderAmerica.com, VOC concentrations can be decreased with ventilation. “Maintaining adequate ventilation can help to control concentrations of existing VOCs within a home, as it is nearly impossible to eliminate VOCs from indoor air,” he writes.

2. Ventilation helps to reduce condensation. Those droplets of water that often form on our windows are created when warm air hits cool surfaces. Because the warm air is no longer able to hold its moisture when it is cooled, it ends up forming water droplets in various parts of our homes. Windows, walls, furniture – these are all locations where condensation may be present in the home. The problem is that these collections of moisture promote the development of mould.

“Condensation is the most common form of dampness and will eventually lead to mould growth,” explains Envirovent.com, “If it is left to develop over time then damp patches may start to appear on walls, which means that wallpaper may peel and ultimately black mould will grow. This leads to musty smells, damage to the fabric of the house and it can even result in health problems.”

3. Ventilation helps to filter our allergens. In last week’s blog, we highlighted some of the issues presented by dust mites. Known allergens, the waste products left behind by dust mites are often triggers for asthma attacks. When we ventilate our homes, we give ourselves better opportunities to filter out such allergens as dust, pet dander, pollen and other irritants that can become trapped and concentrated inside our homes.

“Proper ventilation will help to remove large particles and dust from the air,” says DeTorres, “This can effectively help to reduce allergy symptoms, making the indoor air much more comfortable for allergy sufferers.”

At DF Technical & Consulting Services Ltd., we strongly advocate ventilation of the home all year round. As part of our commitment to helping Canadians live healthy lives, we offer Air Quality Services that work to eliminate health hazards from the air in their homes.
