Winter in Québec is synonymous with snowstorms, hot chocolate… and homes sealed up tight to keep the heat in! Windows that stay shut up for weeks at a time can quickly lead to poor indoor air quality.
Dust, allergens, excessive moisture, or not enough—it can become quite a challenge to breathe healthy air.
Why Purify Your Home’s Air in Winter?
Indoor Air More Polluted than Outdoor?
We spend 90% of our time inside in winter. This means increased exposure to allergens, viruses, and chemical compounds from furniture, cleaning products, and heating appliances. The Public Health Agency of Canada estimates that indoor air can be up to five times more polluted than the air outside. Astonishing!
Reduce the Risk of Seasonal Illnesses
Dry or polluted air can aggravate respiratory problems, irritate nasal passages, and increase the risk of spreading viruses. Not enough moisture in the air can also dry out the skin and mucous membranes, causing discomfort and more frequent infections.
Improve Comfort and Well-Being
Overly dry air can generate static electricity and cause you to wake up with a sore throat. Conversely, too much humidity can lead to mould and the proliferation of dust mites, both of which are harmful to people with allergies or asthma.
Tips to Improve Indoor Air Quality in Winter
Now that we know how important it is to improve our homes’ indoor air quality this winter, what can we do?
1. Air Out Your Home Every Day
No matter how cold it is outside, leave the windows open 5 to 10 minutes a day to freshen the air.
2. Run an Air Purifier
Air purifiers equipped with HEPA filters can very effectively remove allergens, dust, and fine particles from the air. Certain models have an activated charcoal filter that absorbs odours and chemical compounds.
3. Control Humidity Levels
- If the air is too dry (static, dry throat): use a humidifier to maintain humidity between 40% and 50%.
- If the air is too damp (condensation on windows, mould): use a dehumidifier or improve air circulation.
4. Clean Regularly
- Vacuum up dust and dust mites.
- Launder sheets every week and curtains every second week to prevent a build-up of allergens. Throw any fabric cushion covers and couch slipcovers in the wash as well.
- Maintain heating systems by regularly replacing the filters and dusting grilles
5. Check Your Home’s Ventilation Systems
Make sure your air vents aren’t blocked and that the range hood is working well. Proper ventilation will stop pollutants from building up in the air.
6. Adopt Some Air Purifying Plants
Some houseplants like the ficus, the Boston fern, and spider plants help filter out certain toxins from the air and improve its overall quality. It’s not a magic fix, but every little bit counts!
7. Use Natural Cleaning Products
Chemical cleaners release harmful VOCs (volatile organic compounds). Opt instead for natural cleaning alternatives, such as white vinegar and baking soda. Gentle house cleaning products are also available in stores and pharmacies. Read the labels carefully!
8. Beware of Candles and Incense
While they do create a cozy ambiance, certain types of scented candles and incense release fine particles into the air. It’s best to choose beeswax or soy wax candles with cotton wicks.
