PM2.5What haze is
Haze is mostly PM2.5
Haze is dominated by PM2.5, fine particles. The cards above compare against the WHO 24-hour guideline of 15 µg/m³. The WHO annual guideline is lower still, at 5 µg/m³.

The bands
What each level means on a bike.
Riders get a bigger dose than people in cars at the same reading: no cabin, no filter, breathing harder.

Why your visor is not a filter.
NoneVisor filtration
A visor does not filter
A helmet visor keeps wind off your eyes. It does not filter the air you breathe. Visor down or visor up, every breath on the ride is the air around the bike.
≥95%PM2.5 captured
HEPA does the filtering
The Easi Breezi H11 HEPA filter captures at least 95% of PM2.5 before the air reaches your face. The number on the card stays outside the helmet.

Haze FAQ
Three quick answers.
Will it fit my helmet?
Fits any full-face helmet, or any half-face helmet with a visor that goes below your chin. If it doesn't fit yours, we refund.
How often do I change the filter in haze?
Swap when the white filter turns grey, typically every 1 to 2 weeks in heavy haze. A 50-pack lasts a haze season.
Does it work at scooter speeds?
Yes. The fan does the work, not the wind, so it works at a standstill in traffic.
