5 Types of Air Purifiers

Although there are hundreds of different models and brand name air purifiers, there are essentially only 5 different types of air purifiers

These types are based on the technology used in the air purifier, i.e.

• HEPA air purifer
  
• UV Air Purifiers
  
• Ozone Air Purifier
  
• Negative Ion (ionizer) Purifier
  
• Gas Phased (activated carbon) Air Purifier
  

Of course, most if not all modern air purifiers sold in the stores are "hybrid air purifiers" - i.e. they use a combination of 2 or more of the technologies mentioned above.

For example, the air purifier that I personally use has a combination is an ionic air purifier with a germicidal UV lamp (a special Ultra violet lamp that renders bacteria and viruses harmless by destroying their DNA). This is an example of a hybrid air purifier
