Living Near a Busy Road? Dealing with Traffic Pollution

The Invisible Killer: NO2

Diesel cars produce Nitrogen Dioxide (NO2), a harmful gas that causes lung inflammation. Unlike dust, **HEPA filters cannot stop NO2**. Gas passes straight through them. To stop traffic fumes, you need **Activated Carbon**. The more carbon in the filter, the better.

Windows: The Catch-22

In summer, you want to open windows to cool down, but that lets the pollution in. The solution is to run an air purifier near the window (or in the room) to "scrub" the air as it enters, or keep windows closed during peak rush hour.
