Natural gas has been marketed for decades as a clean fuel, but a growing body of research shows that gas stoves can contribute significantly to indoor air pollution, as well as climate change.
The National Construction Code has no minimum ventilation requirements for schools, aged care institutions, pubs, restaurants and health-care facilities.
Cooking with wood and charcoal can raise indoor air pollution to dangerous levels.
Dehumidifiers can help if you’re clever with that you’re trying to achieve, but you should always look to solve the underlying cause. That means, where possible, improving exhaust and ventilation.

3D printers got a lot of attention when DIYers leapt to action to address equipment shortages early in the pandemic, but some everyday items found in hardware stores played a big role, too.

Being indoors with other people is a recipe for spreading the coronavirus. But removing airborne particles through proper ventilation and air filtration can reduce some of that risk.
The dangers of outdoor air pollution are now well known, but those related to the air we breathe at homes and at work are much less so, according to an international study.
Judging by available photographs, the Nauru processing centre definitely has a mould problem.
Several factors play a part when determining what kind of risk high levels of mould exposure can pose to human health.
When a house is better sealed, the quality of ventilation becomes more critical.
Our health depends on the quality of air indoors, where most of us spend 90% of our time. The easiest solution is to open a window, but what if that’s not an option?
