When we talk about creating healthier homes, one of the things that often comes up is VOCs. But what exactly are they, and why should we be concerned about something we can’t even see?
VOCs stands for Volatile Organic Compounds. Essentially, they’re chemicals that can be released into the air from a huge range of materials and products we use every day. They’re found in everything from paints, flooring and furniture through to cleaning products, perfumes and even the clothes we wear.
You know that distinctive smell when you walk into a freshly painted room, open a new piece of furniture or get into a brand-new car? That’s often VOCs being released into the air, a process known as off-gassing.
But here’s the interesting part. Just because you can’t smell something doesn’t mean it isn’t there. Some VOCs have very little smell, and certain materials can continue releasing them long after that initial new-product smell has disappeared.
Are All VOCs Bad?
Not necessarily, and I think this is an important distinction.
VOCs occur naturally in our environment too. Plants, trees, herbs and flowers all release volatile organic compounds. That lovely smell when you walk through a pine forest or crush some fresh herbs? Those are VOCs as well.
Some naturally occurring VOCs have useful properties, while others can be irritating or harmful. The same applies to manufactured compounds. What matters is the particular chemical, how much you’re exposed to and for how long.
Where we need to be more conscious is with certain VOCs found in building materials and household products. Paints, adhesives, sealants, engineered timber products, carpets and furniture can all release chemicals into the air inside our homes.
How Can VOCs Affect Our Health?
Depending on the type of compound and level of exposure, some VOCs can cause headaches, dizziness, irritation to the eyes and throat, and respiratory problems. Certain compounds, such as formaldehyde, are also associated with more serious long-term health risks.
It’s an interesting conversation, particularly when you consider the growing awareness around things like microplastics. While they’re very different substances, there’s a similar principle: we’re becoming more conscious of what the products surrounding us are introducing into our everyday environment.
And when you think about how much time we spend inside our homes, it’s worth considering what we’re actually breathing.
Why Does This Matter When Building a Home?
When we build or renovate, so much of our attention goes towards what we can see. The kitchen, the flooring, the paint colours and the overall design. But how often do we stop to consider what those materials are made from or what they might be releasing into the air?
Good ventilation is important for maintaining healthy indoor air quality, but so is reducing pollutants at their source.
By understanding VOCs and being more conscious of choosing low VOC materials and products, we can make informed decisions that help create healthier indoor environments.
Because at the end of the day, a healthy home isn’t just about being warm, dry and comfortable. It’s also about the quality of the air we’re breathing every day.
