Considering the lengths of our cold winters, it can be understood why homeowners would want to keep their homes sealed and protected from the frigid elements of the outdoors. However, as we’ve discussed in numerous blogs of past, it’s of vital importance that people ventilate their homes. And we don’t just mean opening up the windows!

Why is ventilation so important? First of all, it’s important to remind you that Canadians spend approximately 90% of their time indoors. And, naturally, the majority of that time is spent in their own homes. So, it’s reasonable to suggest that the majority of the air we breathe is found in our homes. If our homes aren’t properly ventilated, we stand to be breathing in poor quality air throughout the majority of our lives.

The Canadian Centre for Occupational Health and Safety lists four main purpose of ventilation. Firstly, it provides a continuous supply of fresh outside air. Secondly, ventilation helps to maintain temperature and humidity at comfortable levels. Thirdly, it reduces potential fire or explosion hazards. And finally, proper ventilation of our homes helps to remove or dilute airborne contaminants.

Although it may appear obvious, it should be highlighted that airborne contaminants in the home lead to respiratory problems and other health issues. Without proper ventilation, homes are susceptible to atmospheres that are filled with allergens, smoke, bacteria, viruses, mildew, mould, fungus and gases. In previous blogs, we’ve also pointed out that odourless and colourless gases such as carbon monoxide and radon pose health risks when they can’t escape our homes.

How can we ensure proper ventilation of our homes? Earlier, we pointed out that the opening of your home’s windows was not the only solution to the ventilation issue. However, it shouldn’t be discounted either. Even when temperatures are low, it’s wise to allow some of the fresh air from outside to circulate with the stale air from inside. You don’t have to keep the windows open for very long in order to improve the indoor air quality of your home.

Health Canada also strongly recommends that you regularly use your kitchen and bathroom exhaust fans. This is especially important during cooking and bathing when excess moisture is being released into the air. “Bathroom and kitchen fans remove pollutants directly from the room where they are created,” they inform. Health Canada goes on to mention that homes are now being built to include mechanical systems that work to bring more of the outdoor air inside.

The Canadian Home Builders’ Association explains further. “Many new homes come with a heat recovery ventilator (HRV), which is a whole-house system that continuously brings in fresh air from the outside to all living areas of your home and exhausts the stale air,” their website explains, “To make sure the system is not simply bringing in problems from the outside, the incoming air is filtered. It is also pre-heated by the outgoing air to save energy—this is the ‘heat recovery’ part of the system.”
