In 2021, we've talked more about indoor air than ever before. The global COVID-19 pandemic has made us all care more about what we're breathing in, how people around us impact our health, and what we need to do to protect ourselves.
Indoor air starts by bringing outdoor air into your home through your air intake and into your furnace, or from doors and windows. It is then brought into your furnace, run through your filter, and distributed throughout your home from various air vents.
The good news is that in Canada, we're already breathing in fairly high quality indoor air. Our outdoor air quality is a lot better than many overpopulated countries, due to less general pollution, smog, and vehicle exhaust. But it still contains many air contaminants that we want to filter out before we breathe it in.
The most common air pollutants are:
- bacteria and viruses;
- volatile organic compounds (VOCs) emitted from paint, cleaning solutions, and other products;
- allergens like mold, dust, dirt, and pollen;
- and industrial gases such as carbon monoxide, carbon dioxide, chlorine, sulfur dioxide, nitrogen oxide and ammonia.
If these pollutants are not properly filtered before the air is circulated throughout our homes, they can get into our bodies and make us sick over time.
Luckily, this is an easy problem to solve with proper air filtration and circulation.
