Negative Ion Latex

Facts about Negative Ions

  • Negative ions are invisible, tasteless and odourless.
  • They can be naturally generated by processes such as sunlight, lightning, waves from the ocean, and from waterfalls.
  • They are normally more concentrated in rural area then in urban area as steel structures, air conditioning and synthetic materials draws off negative ion from the air.
  • Negative ions purifies the air by attracting in large amount to positively charged airborne particles such as dust, virus and germs, making them too heavy to remain airborne and fall out of the air.

Level of Negative Ion and Its effect

0 – 100 Dead Air (Virus and Germs multiplies easily)
500 – 1,000 Normal air in buildings with low pollution and opened windows
1,000 – 5,000 Fresh air that meets the minimum requirement for a healthy body
5,000 & up Exceptionally fresh and clean air found normally in the mountains
50,000 & up Pure air, an environment condition where bacteria and germs cannot thrive

Example of negative ion concentration in various environment

Building, with central heating/Air conditioning 0 – 250
Airplane 20 – 250
Smoky indoor air 0 – 100
Normal indoor air (windows open) 250 – 500
Urban Air in average industrial city 250 – 750
Country Air 1,000 – 2,000
Mountain Air 1,000 – 5,000
Inside Caves 5,000 – 20,000
Waterfalls 25,000 – 100,000
