Protecting Myself From Air Pollution

This is inspired by Bryan Johnson.

I am using N95 mask while outside. I am planning to make a DIY air purifier for house.

My notes:

  • Annual average AQI of Gulbarga
    • 102
  • AQI categories
    • 0–50: Good, No risks
    • 51–100: Moderate, Acceptable. Sensitive individuals may experience minor health effects.
    • 101–150: Unhealthy for Sensitive Groups, Sensitive groups may experience health effects. General public is fine.
    • 151–200: Unhealthy. Everyone may experience health effects; sensitive groups may experience more serious effects.
    • 201–300: Very Unhealthy. Health alert for everyone; significant health effects.
    • 301–500: Hazardous. Emergency conditions; everyone should avoid outdoor activity.
  • Steps to be taken
    • Mask
      • Options
        • N95
        • N99
      • According to my research, N95 is good enough for my use case.
      • Valve
        • There’s with and without valve.
        • With valve, exhale won’t be filtered.
        • This makes breathing easier.
        • This is OK if I am not contagious.
    • Purifier
      • Types
        • HEPA
          • Standard, but maybe costly
          • High-Efficiency Particulate Air filter
          • Removes
            • PM2.5 and PM10 (dust, smoke, pollution)
            • Pollen and allergens
            • Bacteria and viruses
            • Mold spores
            • Pet dander
            • Fine ash and soot
        • Corsi-Rosenthal box
          • Invented during pandemic
          • DIY and cheap
