For instance, advanced designs for new homes are increasingly incorporating mechanical features that introduce outdoor air into the home through the HVAC (heating, ventilation, and air conditioning) system. This innovation not only improves indoor air quality but also reduces the need for energy-intensive cooling and heating processes, thereby conserving energy and diminishing pollution.

Energy-efficient heat recovery ventilators, also known as air-to-air heat exchangers, are a prime example of these innovative systems. They recover the thermal energy from outgoing air to preheat or precool incoming outdoor air, thereby reducing the energy required for heating or cooling. This technology is particularly effective in temperate climates, where it can significantly decrease the energy consumption associated with maintaining comfortable indoor temperatures.

To further enhance the efficiency of heating systems, individuals can take several proactive measures. One such action is to adjust gas stoves to decrease emissions, as recommended by the US EPA. Another suggestion is to opt for a fan instead of air conditioning, as air conditioners are significant energy consumers. Programmable thermostats can also be used to regulate temperatures efficiently, with settings of 78°F in summer and 68°F in winter.

Additionally, when replacing appliances, it is advisable to look for energy-efficient alternatives, often denoted by an "energy star" label. These products are designed to minimize energy consumption, thereby reducing the environmental footprint and contributing to lower pollution levels. By adopting these energy-efficient appliances and heating systems, individuals can play a proactive role in mitigating outdoor air pollution while also enjoying the economic benefits of reduced energy costs.
