Helmet air filter guide
Standard motorcycle helmets do not have air filters. They have vents, and no helmet standard asks for filtration.
For filtered air you have three routes: a helmet with a built-in filter, a mask under your helmet, or a clip-on system that feeds HEPA-filtered air into the helmet you already own.
Easi Breezi is the clip-on route. It mounts on your scooter or motorbike, runs off the bike, and sends air through an H11 HEPA filter (supplier-rated 95.5% at the most penetrating particle size, EN 1822) and a tube that clips magnetically under your chin bar. It fits most full-face, modular and open-face helmets.
