When we think of air pollution, we often imagine smoggy cityscapes or smoky industrial areas. It’s easy to assume that the air inside our homes and offices is safer, but the truth might surprise you. In many cases, indoor air quality can be considerably worse than the air outside. Let’s dive into why that is and what you can do to ensure the air you breathe indoors is as clean as possible.
Why is indoor air quality worse?
Lack of ventilation. Modern homes are designed to be energy-efficient, which often means they’re sealed tight to keep the heat in during the winter and out during the summer. While this is great for your energy bills, it’s not so great for air circulation. Without proper ventilation, indoor pollutants get trapped inside, leading to higher concentrations of contaminants.
Household pollutants. Everyday activities like cooking, cleaning, and even decorating can release pollutants into the air. For example:
– Cooking can release tiny particles and gases, especially if you’re frying or grilling.
– Cleaning products often contain volatile organic compounds (VOCs) that evaporate into the air, potentially irritating your respiratory system.
– Furniture and paints can off-gas formaldehyde and other chemicals long after they’re installed or applied.
Biological contaminants. Mold, dust mites, pet dander, and pollen can all accumulate indoors, especially in damp or poorly ventilated areas. These biological contaminants can trigger allergies and asthma or even lead to more serious respiratory conditions over time.
Outdoor pollutants sneaking indoors. Outdoor air pollution can make its way inside through open windows, doors, and any cracks or leaks in your home’s structure. Once inside, these pollutants can become trapped and concentrated, particularly if ventilation is poor.
Radon. This naturally occurring radioactive gas can seep into homes from the ground and become trapped, especially in basements and ground-level rooms. Long-term exposure to radon is a leading cause of lung cancer.
What can you do about it?
Now that we know why indoor air quality can be worse than outdoor air, let’s talk about what you can do to improve it.
Increase ventilation. One of the simplest ways to improve indoor air quality is to let fresh air in. Open windows and doors when weather permits, and consider using exhaust fans in kitchens and bathrooms to remove pollutants directly from the source. If your home is tightly sealed, you might also look into a mechanical ventilation system to ensure consistent air exchange.
Use air purifiers. High-efficiency particulate air (HEPA) filters can capture many airborne particles, including dust, pollen, and pet dander. Consider investing in an air purifier, especially if you have allergies or live in an area with high levels of outdoor pollution.
Choose low-VOC products. When painting or buying new furniture, look for products labeled as low-VOC or no-VOC. These products emit fewer harmful chemicals, helping to keep your indoor air cleaner.
Regular cleaning. Dust and vacuum your home regularly to reduce the buildup of allergens. Use a vacuum with a HEPA filter to trap dust particles rather than just redistributing them. Don’t forget to clean or replace the filters in your HVAC system regularly as well!
Control humidity. Keep humidity levels between 30-50% to prevent mold growth and discourage dust mites. You can use a dehumidifier in damp areas like basements or bathrooms, and an air conditioner can help maintain lower humidity levels in the summer.
Houseplants. Certain houseplants can help purify the air by absorbing some airborne toxins and releasing oxygen. However, keep in mind that while plants can be beneficial, they should be used as a complement to other air quality measures rather than a sole solution.
Test for radon. Since radon is colorless and odorless, the only way to know if it’s present is to test for it. You can purchase a radon test kit online or hire a professional to assess your home. If radon levels are high, mitigation systems can be installed to reduce the risk.
