O2 Armor makes nasal filters for people who work in dust, smoke and debris every day. Our filters sit discreetly inside the nostrils, so you can keep talking, drinking water and getting the job done while the filter captures fine airborne particles before you breathe them in.

O2 Armor is built for welders, fabricators and the trades, and you'll find it in woodshops and furniture restoration, on construction sites, out on dusty trails and anywhere else the air is full of particles. We want every breath you take on the job to be a little cleaner, for as long as you do the work you love.
