Why air purifier is important

  1. 1. WHY AIR PURIFIER IS IMPORTANT
  2. 2. INTRODUCTIO N
  3. 3. OVERVIEW  Outdoor Air Pollution  PM 2.5 and PM 10  Indoor Air Pollution  VOC  Dustmite
  4. 4. HAZE - Haze is caused when sunlight encounters tiny pollution particles in the air especially PM 2.5. - More pollutants, more absorption and scattering of light. - Natural or manmade air pollutant. - Natural  windblown dust, soot from wildfires, - Manmade  Vehicles, industrial fuel burning, manufacturing operations.
  5. 5. - Complex mixture of extremely small particles and liquid droplets. - Size of particles linked to their potential for causing health problems. - PM10  inhalable coarse particles, 2.5~10 micrometers. Eg, near roadways and dusty industries. - PM 2.5  fine particles, smaller than 2.5 micrometers. Eg, forest fires, gases from power plants, industries. - Premature death in people with heart or lung disease, aggravated asthma, increased respiratory symptoms such as irritation of airways, coughing or difficulty breathing. PARTICULATE MATTER (PM)
  6. 6. Indoor air is 2-5 times polluted than outdoor air!!!! INDOOR AIR POLLUTION Is outdoor air quality better than indoor air quality?
  7. 7. VOC - Volatile organic compounds are organic chemicals that have high vapor pressure in room temperature. - Large number of molecules evaporate to surroundings. - Harmful VOCs typically not acutely toxic, but have compounding long-term health effects. - Major manmade VOCs: Protective coatings, paints, CFCs, methylene chloride. - Newly furnished buildings or furniture.
  8. 8. DUSTMITE
  9. 9. >10micrometer <10micrometer
  10. 10. Refurnished buildings CONCLUSION SAVE OURSELVES, GET A BETTER AIR QUALITY THERE IS NO DUPLICATE LUNGS
