What Are Various Air Purifier Technologies in The Market?

Air purifiers in the market are available in various shapes, sizes, and colours. But most crucial point is that all of them work in different ways and are based on different technologies.

It is good to know about these technologies before you make an investment in any air purifier for your premises.  Depending on the size of the room, one can go in for a large or small room air purifier.

Most common types of purifiers are:

  • Activated Carbon technology
  • HEPA technology
  • Negative ion
  • UV technology
  • Ozone

HEPA Technology:

HEPA stands for High Efficiency Particulate Air and has been made use of for filtering particles, since many years. HEPA filters maintain a standard for capturing 99.97% of particles which are bigger than 0.3 microns.  Only particles larger than 10 microns can be detected by the human eye. Thus, HEPA filters trap viruses, bacteria and chemicals, invisible to the human eye. HEPA thus provides a sanitary environment and does not emit harmful by-products.

Activated Carbon:

Activated carbon is a type of carbon that has been subject to processing to make it highly porous and to create a big surface area, ideal for absorption. Activated carbon filters are made of many molecular size pores which have high capacity for chemical bonding and absorption. Thus, they can capture odours, tobacco smoke, gases and chemical emissions. Recontamination is prevented since pollutants, once captured are not released ever again.

UV Technology:

This technology is mostly used with particulate filter systems, as they don’t get rid of particles that are airborne. But it is very efficient at killing bacteria and viruses. Such air-purifiers have installed UV lamp which kills micro-organism that pass via the UV rays.

Negative Ion:

These purifiers use chemical injections to clean air. An ion is a particle with a negative or positive charge. They get this charge by losing or gaining an electron. They magnetically attract air borne particles such as dust or pollen. The new particles formed this way become too heavy to stay in the air. Thus, these particles drop down and accumulate on solid objects like furniture in the room.

Ozone:

These purifiers generate ozone which may disrupt the growth of certain micro-organisms. But this technology is not popular as it damages the health of human beings as well as the environment.

These are the main types of air purifiers. One can do research for online air purifier retailers to land the best.
