For people living in apartments, fresh air is a precious resource. To keep the air healthy in these spaces, what you can do is to replace your HVAC filters more often than normal,
install ventilation fans, and keep the house free of dust to reduce particulate matter in the air.
If you live in a home with more windows, you can open them at regular times each day to let fresh air in. However, you have to take note that outdoor pollution can also enter and increase PM2.5 levels indoors. Improving the filter used in your HVAC system can significantly reduce the amount of PM2.5 entering your home. Houses with bigger spaces can also put up plants to help improve the air.
At your workplace, you need to make sure that the building’s ventilation system is working efficiently and is able to ensure an effective flow of fresh air so that the stale air inside the workplace can be dissipated.
Aside from good ventilation, our activities can also have an impact on our indoor air.
Cooking, for example, generates a high amount of PM2.5. Maintaining good ventilation is crucial to lessen health risks.
