When the cold comes, we tend to caulk our house to keep the heat. Yet this habit can harm indoor air quality. Did you know that the air inside our homes is up to 7 times more polluted than the outside air? Household products, humidity, dust... everything accumulates, and this can affect your health. So, even in winter, it is crucial to ventilate one’s home, but not in any way at any time.
How long to aerate in winter?
You don’t have to leave your windows open for too long to renew the air effectively. Here are the good practices:
Open the windows wide for 5 to 10 minutes, twice a day.
Create a stream of air by opening several windows or doors simultaneously.
Focus on the key rooms: bedrooms, living room, kitchen.
This method makes it possible to expel polluting particles and reduce humidity, while limiting heat loss.
When to air to avoid pollution photos?
In winter, outdoor air can also be polluted, especially in urban areas. Here are the most favorable moments for aerating:
Between 8 a.m. and 11 a.m.: pollution levels are often lower.
After 10 p.m.: circulation and human activities decrease, which purifies ambient air.
Avoid ventilating between 2 p.m. and 6 p.m., periods often marked by photos of pollution.
