How Air Purifiers Can Break The Chain of The Current Virus Spread?

Best Corona Virus Air Purifiers

Covid-19 or the coronavirus outbreak spreads by close person to person contact, especially when a person who is infected coughs or sneezes. The virus particles are transmitted through water droplets that float in the fine mist. Airborne transmission of coronavirus is a serious concern as coughing is one of the main symptoms of the infection.

Thus apart from frequent handwashing and avoiding close person to person contact, the only way to reliably remove the virus particles from the air is to cleanse the entire volume of air in a room, multiple times in a day. This is exactly what the virus particles are up to. They are highly effective in removing pathogens from the air and circulating pure air into the room many times a day
Health care practitioners are also advising people to make use of an air-purifying system to combat airborne transmission of illnesses and to support overall wellness.

Different Types of Filters Available in Air Purifiers:

There are many different types of filters available with air purifiers, and some of them have a combination of filters to render multiple levels of filtrations. Let us discuss the different types of filters in air purifiers here.

  • HEPA filter
  • Ionic filtration
  • Carbon filtration
  • Ultra Violet or UV filtration system

HEPA Filter:

HEPA or high-efficiency particulate air filtration system is the gold standard for air purification. It consists of a dense paper filter, that traps all the airborne contaminants. It also serves as a driving mechanism behind the top end purifiers. There are a number of filters that make use of HEPA to remove up to 99.97% of all microscopic particles that are as small as 0.3 microns in size. But it is important to check for the true HEPA designation while shopping for the HEPA air purifier. This filter is capable of removing mold spores, pollen, hair, pet dander, pollen, and visible smoke. It is highly efficient and traps particles and doesn’t send them back into the air.

Ionic Filtration:

This technology to clean air operates by emitting a cloud of charged ions into the air, that latches onto the airborne contaminants. It also forces the impurities to fall on the floor and other nearby surfaces. Some ionic air purifiers include an electrostatic collection plate that attracts these particles and removes them from the room. These filters are capable of removing spores, fungi, dust, pollen, bacteria, viruses and some visible smoke.

Carbon Filtration:

These types of filters make use of a special form of activated carbon that consists of millions of absorbent pores that are absolutely tiny in nature. These pores are capable of creating a large surface area and is thus pretty useful in trapping gases, fumes and odors. The carbon filters are not capable of removing microbes that are responsible for causing health issues. They are pretty much useful in getting rid of the particles that emit unwanted smells. Thus these filters help in making the home smell clean and fresh. They are highly capable of removing gas and chemical fumes, cooking smoke, smell and odor from pets, paint smell, etc.

Ultra Violet or UV filtration System:

This type of filtration system is entirely different from the other types of filters that are mentioned here. UV filters make use of an invisible light that attacks the pollutants rather than passing pollutants through a physical filter. The ultraviolet light is contained inside the purifier and is not released inside the room. The purifiers make use of the UV-C band of the ultraviolet spectrum. The band is also completely safe for humans and does cause any negative side effects.

The ultimate goal of this filter is to kill viruses and bacteria inside the home by attacking its molecular DNA structure. This results in a clean and a sterilized environment that is free of particles, capable of creating airborne respiratory infections.
