With allergy season around the corner, it’s more important than ever to have good indoor air quality. Most of our time is spent indoors and having poor air quality can cause allergies, breathing problems, and general discomfort. Let’s take a look at the most common types of indoor air pollutants.
1. Dust and Dust Mites
A common trigger for allergies and asthma are dust and dust mites. Dust collects just about everywhere, on the shelves, carpets, curtains, and even bedding. Dust mites on the other hand absolutely love warm and humid environments.
What helps: Wash your bedding regularly, vacuum carpets with a HEPA filter, and don’t forget to clean or replace your AC filters.
2. Mould and Mildew
Mould often thrives in damp, poorly ventilated areas like bathrooms, kitchens, and around windows where condensation builds up. It releases spores into the air, which can make breathing difficult and worsen allergies or asthma. Mould can be damaging to both your health and home.
Prevention: To prevent mould, focus on reducing moisture. Control indoor humidity, repair any leaks, and improve ventilation to keep the air moving.
3. Pet Dander
Pet dander is another common trigger that all pet owners should know. It is made up of tiny skin flakes and hair from cats, dogs, and other animals. Pet dander can linger in the air and stick to furniture, clothing, and bedding. Regular grooming and frequent cleaning help reduce dander build-up and keep your indoor air healthier.
4. Tobacco Smoke
Cigarette smoke contains thousands of harmful chemicals. The smoke lingers in the air long after smoking stops and can cling to fabrics and surfaces, a problem often called “third-hand smoke.” The most effective way to protect your indoor air quality is by keeping your home completely smoke-free.
5. Volatile Organic Compounds (VOCs)
VOCs are emitted from everyday items like paints, cleaning products, air fresheners, and even some furniture. When exposed to high amounts, it can cause headaches, dizziness, and also irritation. This can be prevented by choosing low-VOC products and improving ventilation inside your home.
6. Carbon Monoxide (CO)
Carbon monoxide comes from gas heaters, stoves, fireplaces, and other appliances that aren’t properly ventilated. It’s colourless and odourless, but in high concentrations it can be very dangerous. Installing carbon monoxide detectors and having your appliances serviced regularly is the best protection you can have.
7. Cooking Fumes
Cooking releases smoke, grease, and tiny particles into the air, which can affect your lungs over time if the kitchen isn’t well ventilated. To reduce exposure, use an extractor fan while cooking or open windows to let fresh air circulate.
8. Pollen
With tree pollen peaking around August to October and grass pollen from September to March, it’s hard for people with allergies and hay fever to escape. Outdoor pollen enters your home through open doors, windows, or even clothing.
Tip: Keep windows closed on high-pollen days, and make use of air purifiers where possible.
Conclusion
Indoor air pollutants are common but manageable. Regularly cleaning your home, having good ventilation, and keeping up with preventative maintenance of heating/cooling systems can significantly improve indoor air quality.
