  Some of the more dangerous pollutants are ultra-fine particles (less than 100nm in size). I wonder how effective these masks are for trapping these particles. I can only find information on how well they trap particles larger than 100nm.

    Many people don't realize how dangerous small particles can be over many years. Something that doesn't seem dangerous can cause scars on lung tissue with constant exposure to it over many years. My dad has idiopathic pulmonary fibrosis or IPF it's probably from breathing in small particles over the years which causes scarring of lung tissue. Although the idiopathic part means how it occurs is not known for sure. He worked a blue collar job and often breathed in dust from various things. Lungs are only for air don't mess with your lungs!

  I used a Respro while mountain biking in AZ; when breathing & inhaling very heavily there is some resistance. But otherwise I liked it. There is also this inhaler containing ectoine, but this wouldn't protect against particles entering the brain via olfactory nerve: "An inhaler that protects the lungs against air pollution has been developed by scientists and could help the many millions of people affected by toxic air to avoid its worst effects." https://www.theguardian.com/environment/2016/sep/16/new-inhaler-protects-lungs-against-effects-of-air-pollution https://www.theguardian.com/environment/2016/sep/16/new-inha...
