1. Make indoor air monitoring more affordable and convenient:Monitoring indoor air quality isn’t easy—traditional indoor air-monitoring devices are expensive, which has limited their widespread adoption. Fortunately, emerging low-cost sensors and smart Internet of Things (IoT) devices have proven to be a viable solution. While the accuracy and reliability of these new tools still have room for improvement, given that the technology is still in its early stages, they hold significant potential for expanding access to indoor air-quality data—and providing crucial insights that can inform much-needed interventions.

2. Respect cultural practices and guide behavioral change:Cultural habits further obscure the issue. Open-flame cooking or wood-fired cooking remains widespread, especially in situations where electricity costs are high. Changing people's habits requires not only public education but also cultural sensitivity. While respecting tradition, we must also promote cleaner energy alternatives.

3. Transitioning to Clean Energy:Even with cleaner technologies available, adopting clean energy solutions like electric cooking or clean heating systems remains challenging—largely due to high upfront costs and limited infrastructure. We need to shift from awareness to action. Clean energy solutions must be affordable, accessible, and reliable. This calls for expanding financing options, strengthening supply chains, and demonstrating to people how these technologies can seamlessly integrate into their daily lives.

4. Improve infrastructure:Poor ventilation is a common issue in many homes and buildings, leading to the gradual buildup of indoor pollutants. Addressing this problem requires improvements to infrastructure—both at the regulatory and design levels. While challenges persist across different regions due to insufficient policy attention, funding constraints, and the practical difficulties of retrofitting existing structures, establishing clear ventilation standards and supporting basic improvement measures can significantly enhance indoor air quality.

5. Give equal regulatory attention to indoor and outdoor air:The policy priority for indoor environments remains far lower than that of outdoor settings, which continues to be a critical challenge in effectively addressing this issue. To close this gap, we need to place indoor air quality squarely at the forefront of policy priorities and integrate it into broader health and environmental strategies. Without giving indoor environments the same level of attention, efforts to improve air quality and safeguard public health will inevitably continue to face significant obstacles.

The air we breathe indoors is just as crucial as outdoor air—yet it continues to be seriously overlooked. If we truly want to safeguard global health, we must delve deeper into this issue, ensuring that indoor air quality shifts from being an "afterthought" to a top-priority topic on the policy agenda.
