Pollutants


Pollutants are unwanted, harmful materials in the air. Pollutants that can affect air quality can be classified as primary or secondary.
Usually, primary pollutants are directly emitted from a process, such as ash from a volcanic eruption, the carbon monoxide gas from a motor vehicle exhaust or sulfur dioxide released from factories. Secondary pollutants are not emitted directly. Rather, they form in the air when primary pollutants react or interact. Some pollutants may be both primary and secondary: that is, they are both emitted directly and formed from other primary pollutants.
Some major primary pollutants produced by human activity include:

  • Sulfur oxides- Since coal and petroleum often contain sulfur compounds, their combustion generates sulfur dioxide
  • Carbon monoxide - a colorless, odorless, non-irritating but very poisonous gas. It is a product by incomplete combustion of fuel such as natural gas, coal or wood. Vehicular exhaust is a major source of carbon monoxide.
  • Carbon dioxide¬† - a colorless, odorless, gas emitted from sources such as combustion and cement production.

The Aireox Air Purifier D-Model with our Purafil/Carbon Mix Filter is recommended.
