Prioritise health in your next renovation project and achieve
an allergen-free home
There’s a particular kind of pride that comes with finishing a renovation. The fresh paint smell. The way light hits a new surface. The sense that you’ve invested in something that will last. What most of us don’t consider, but probably should consider, is that the decisions made during those months of planning and building have a direct impact on something far more important than aesthetics: the quality of the air your family breathes every single day.
It’s a confronting statistic, but indoor air quality can be up to five times worse than outdoor air. We seal our homes, insulate them, draught-proof them. In doing so, we trap allergens, chemicals and moisture with nowhere to go. The result? A home that looks impeccable and quietly works against you.
For the one in nine Australians living with asthma and one in five with allergies, this isn’t a minor inconvenience. It’s a daily health reality. But even for households without those specific sensitivities, the case for renovating with air quality in mind is compelling. A home that supports your health isn’t a compromise. Done well, it’s the ultimate upgrade.
The hidden culprits most renovators overlook
The obvious renovation hazards, including asbestos, lead paint and silica dust, are well understood. It’s the invisible, ongoing ones that catch people off guard. Many conventional building products contain volatile organic compounds (VOCs), including formaldehyde, phthalates and synthetic fragrances, that continue emitting particles into your air long after the tradies have packed up. That new-home smell people sometimes celebrate? In many cases, it’s off-gassing.
Beyond building materials, some of the most common allergen sources in the home are things we’d never think to question. Old carpet accumulates years of dust mites and pet dander in a way that’s essentially impossible to fully clean. Blind and curtain fabrics, particularly in bedrooms, trap allergens at exactly the level where we spend eight hours a night breathing. A bathroom without adequate ventilation creates the persistent moisture that mould needs to thrive behind your beautiful new tiles.
The challenge is that most of these triggers are invisible. You can’t see a dust mite or detect formaldehyde at low concentrations. But if you or someone you love has asthma or allergies, your body very much notices them, often in ways that get written off as seasonal, stress-related or just “how things are”.
Where to focus your attention, room by room
A healthier home renovation doesn’t require ripping everything out and starting again. It’s about making considered choices at key decision points: the moments when you’re already choosing between options, and one of those options simply works harder for your health.
The bedroom is where most of us should start. We spend roughly a third of our lives in this room, which means it has an outsized effect on our health. Window treatments are the most overlooked source of allergens in the bedroom. Fabric that traps dust traps dust mites, full stop. Replacing curtains with Luxaflex® roller blinds made from Bekaert Deslee’s Sensitive Choice® approved fabrics, including the Haven and Sorelle blockout collections, is one of the more elegant solutions available. Both are anti-dust mite, anti-bacterial and anti-fungal, with anti-static technology that minimises dust attraction in the first place. They’re also genuinely beautiful: locally developed, thoughtfully designed, and made to last.
The bathroom and laundry are the humidity hotspots. Without proper ventilation or active dehumidification, moisture lingers and mould follows, sometimes visibly but always persistently. De’Longhi’s Sensitive Choice® approved dehumidifiers work in two ways: eliminating excess moisture from the air while simultaneously filtering it through a four-stage system that captures pollen, dust, bacteria and pet dander. It’s the kind of quiet, unglamorous work that makes a genuinely significant difference to how a home feels to live in.
Heating is another category worth reconsidering. Gas heaters introduce combustion byproducts into your indoor air, something that rarely comes up in showroom conversations but matters considerably for those with respiratory sensitivities. De’Longhi’s panel and convector heaters offer a Sensitive Choice® approved alternative: efficient, silent, electric warmth that integrates cleanly into any interior without any air quality trade-off.
Living areas benefit most from a considered approach to air conditioning and purification. Modern Hisense air conditioning and purification systems, which are also Sensitive Choice® approved, go beyond temperature control, actively filtering allergens throughout your living spaces. If you’re planning an HVAC upgrade as part of your renovation anyway, choosing a system that improves your air quality rather than simply circulating it is a decision you’ll feel the benefit of immediately.
The one symbol worth knowing
Navigating “allergy-friendly” product claims can be exhausting, and a lot of it is marketing. The Sensitive Choice® program, run by the National Asthma Council Australia, exists specifically to cut through that noise. Products carrying the Sensitive Choice® blue butterfly have been independently reviewed and approved by an expert panel. It is not a self-certified badge or a paid accreditation. It’s the clearest signal available that a product has been genuinely evaluated for its impact on people with asthma and allergies, not simply positioned that way.
The program now covers an impressive and growing range of categories: window furnishings, dehumidifiers and heaters, air conditioning and purification systems, and more. When you see the blue butterfly, someone independent has already done the verification work for you.
The renovation checklist worth saving
Whether you’re undertaking a full renovation or making targeted upgrades room by room, these are the decisions that have the greatest impact on your home’s health.
Choose low-VOC or zero-VOC paints and finishes. Look for Sensitive Choice® approved blind and window fabrics rather than curtains that accumulate allergens. Prioritise hard flooring over carpet in bedrooms. Install adequate bathroom exhaust ventilation, which is unglamorous but genuinely important. Consider a dehumidifier for laundry and bathroom areas, particularly in humid climates. Look at whether your HVAC system includes air purification, not just temperature control. Opt for electric panel heating over gas where possible. Use formaldehyde-free cabinetry and MDF products. Test for existing mould before closing up walls. And ventilate rooms thoroughly after renovation before moving back in, as that off-gassing period matters.
None of these choices require compromising on the home you’ve envisioned. In most cases they’re decisions between two options that look identical on the surface, where one simply works harder for the people living inside it. That, in the end, is what good renovation really means.
