Why YSK: Back in 2020 when Australia had our massive wildfires I still had to drive to work everyday in the smoke. I also went and got my car serviced around the same time and they showed me how dark my cars air filters had gotten after just a few weeks of those conditions. The air filters in cars aren’t designed to filter out so many particles so as soon as you can you should get them replaced.
Well I’ll be damned. Never thought of that but it makes sense. I imagine it might be the same if there are a lot of bad air quality days? (Looking at you Canada). I’ll check mine later.
