Cool, the study was done at the University of North Sumatra.
From the Abstract/ Conclusion: "All three type of masks such as surgical mask, N95 mask, and carbon mask was effective to reduce CO levels from air pollution with the most significant was N95 and carbon mask. Fabric mask has the poorest protection from CO levels."
I'm surprised at the N95 being effective. And expect the best results would come from a fresh, well fitted, carbon filter. As for myself, I do my best to ride where the motor vehicles are not present. Our town, like many, has a decent bike/ walking trail system.

Seriously, those things are the worst.

The landscape company that maintains the condo I live in uses them exclusively to “clean” the paved common areas and every time they do, the dust blows up into the air, and then 15 minutes after they pass it resettles right back where it came from, while also leaving a fine film of dust on every flat surface in the apartment, as well as small piles of long-accumulated gunk in every corner and crevice. I can’t help but think how much better and quieter this place would be if they just used brooms.

I hate the two-stroke models. Electric aren’t so bad.

Yeah, I was talking about the former. Electric ones are totally fine.
But the fromer ones are really super bad. They put out carbon monixide and all kind of dust and shit … micro plastics whatever, fuck you. Point is they are so much worse than you’d think.
The exhause from those is worse than a diiesel VW with the cheating software disabled.

Agree 100%. They should be banned…some places have already banned them and it’s a spreading idea.

I got a dewalt one for pretty cheap since i already had the batteries for it, and i don't see anything wrong with it. Plenty of power and not a lot of noise.
