The Air You Breathe
How to choose low-VOC paints and finishes for a healthier home.
When investing in a significant renovation, the most important details are often the ones you can’t see. We spend nearly 90% of our time indoors, yet indoor air quality is one of the most consistently overlooked elements of a home. Choosing low-VOC paint or the right materials isn’t just about how a space looks or feels. It’s about what it’s putting into the air you and your family breathe every day.
What VOCs are and why they matter
That sharp smell in a freshly painted room? That’s Volatile Organic Compounds, or VOCs, releasing into the air as the paint dries. They’re chemicals found in many common building and finishing products that evaporate at room temperature and linger long after the work is done.
Not all paints are equal when it comes to VOC content. Lower-cost paints contain fewer solids and pigments, which means three or four coats to achieve the finish a high-quality paint reaches in two. Every additional coat means more off-gassing, more time, and more chemical load in your home during the drying process.
Investing in a high-quality, low-VOC paint gets you a better finish with fewer coats and significantly less chemical release. It’s one of those decisions that pays off immediately and over time.
The hidden VOC offenders
Paint gets most of the attention, but it’s rarely the only source. Many installed materials continue off-gassing long after the contractors have left, and they’re easy to overlook during the specification process.
The most common culprits:
- Adhesives and sealants used during flooring, countertop, and trim installation
- New cabinetry and millwork made with manufactured wood products and synthetic finishes
- Carpet and underlay, both of which can release compounds for months after installation
If you’re doing a full renovation, review every material category, not just the paint.
Bringing nature in: biophilic design as living filtration
One of the most effective ways to actively improve air quality is through biophilic design. Incorporating living plants into a space, whether through a feature plant wall or strategically placed large-scale greenery, does more than add visual warmth.
Certain plant species absorb common indoor pollutants through their leaves and root systems in a process called phytoremediation. A large plant installation also acts as a natural humidifier, releasing moisture that counteracts the dry, stagnant air common in climate-controlled homes.
It’s a layer of design that works around the clock without you thinking about it. We wrote about how sensory details shape the feeling of a home in ‘Crafting Calm‘.
The bake-out: clearing the air before you move in
Even with the most carefully specified materials, any renovation involves residual off-gassing from new finishes and installations. The bake-out is the intentional final step that clears it out before you start living in the space.
The process involves running your HVAC system and exhaust fans at full capacity while cycling in fresh air from outside over a sustained period. This accelerates the release of remaining compounds and clears the bulk of the chemical load before the space is occupied. Health Canada identifies VOCs as a primary indoor air contaminant, which makes this step worth building into your renovation timeline.
It’s a simple step that most people skip and one of the most effective things you can do for the long-term air quality of your home.
Design takeaways
Specify a low-VOC paint supplier that stocks widely, so touch-ups stay simple
- Review adhesives, millwork, and carpet during specification, before they’re installed
- Build a bake-out into your renovation timeline before move-in day
The bigger picture
A well-designed home considers everything that goes into it, not just what you can see. Specifying low-VOC materials, incorporating living elements, and clearing the air before move-in all contribute to a healthier, more comfortable everyday environment.
On a full-service interior design project, material health is part of the specification process from day one, reviewed alongside every finish decision. If you’re earlier in your planning, our 90-minute design consultation is the right place to start the conversation about materials, air quality, and how your renovation comes together.
