Air disinfection vs air purification



Bombay (Maharashtra) [India], July 28 (ANI / BusinessWire India): COVID-19 has wreaked havoc on human lives for over a year, and there are multiple sources of information and misinformation about plausible solutions to these airborne infections.

Some bloated and fictitious communications regarding the prevention of such airborne infections can give consumers a false sense of security.

With the evolution of airborne infections, it is essential that people recognize that many viruses, bacteria [particularly TB], and fungal infections are spread through the air. The danger of being exposed to infections is especially high in crowded areas. The covid epidemic has clearly demonstrated how the infection spreads in confined and overcrowded areas.

As a result, air disinfection devices have become a need for closed and overcrowded commercial spaces such as shopping malls, restaurants, hotels, gymnasiums, hospitals, etc. where natural ventilation is insufficient. In terms of residential areas, the increasing use of air conditioners in confined rooms has intensified the problem of airborne infection transmissions.

Air disinfection and air purification devices: To begin with, the terms air disinfectant and air purifier have often been used incorrectly and interchangeably. Air disinfection involves the removal of up to 99.99% of the microbial load. Air disinfectants remove microbes from the air by reducing their concentration by adding fresh air, trapping infectious particles or destroying them.

Air purification or air filtration refers to the process of cleaning or diluting the air and may include the removal or dilution of certain chemicals or particulate pollutants, as well as the removal or neutralization of microorganisms. Purification / filtration is a broad term that does not specify at what “level” purification occurs.

Air disinfection devices play an essential role in reducing the transmission of infectious diseases from one infected family member to another, as well as in the presence of immunocompromised people. People on cancer treatment or the elderly in fragile health, those on immunosuppressants for a medical problem or after an organ transplant or those infected with HIV have a weakened immune system and access to more air. pure would reduce their risk of infection.

Technology: The availability of air purification and disinfection devices is abundant in the market, which are generally categorized into two types: one that kills microbes and the other that traps microbes. Trap technologies include the use of HEPA filters in central air handling units (air handling units), electrostatic precipitation (ESP), carbon filters, PCOs (photo-catalytic oxidation), hybrid ionizers, etc. Technologies that kill include the use of UV light, hot air sterilization, chemical fumigation (using H2O2 or formaldehyde, etc.) and the latest technology being cold plasma.

Each technology has its own drawbacks, such as the fact that filters can “trap” microorganisms but do not kill them, and that if filters are not cleaned regularly they can become a source of infection due to colonization. bacterial.

UV light technology affects DNA replication of all types of cells, including microbes, but continued exposure to UV light can harm human health.

Ionizers, on the other hand, release charged particles (positive and negative ions) into the environment.

Chemical fumigation is time consuming and cannot be used in occupied rooms due to the toxicity of fumigants.

All of these technologies are beneficial for certain scenarios. There isn’t one device that can be used to solve all real world problems.

On the contrary, very low energy cold plasma – NanoStrike technology totally destroys anything that comes in contact in a matter of milliseconds. Since this plasma is “contained” in a device, the air which passes through such a device completely destroys all microbes and “clean and disinfected” air is released into the environment. Thus, there are no harmful side effects of by-products or discharges on the occupants of the room.

Factors to consider when selecting an air disinfectant for your home, office: A. Certifications: Air disinfectants used to purify air for human consumption must have certificates that state: Medical safety (ozone emission, etc.) Electrical and electromagnetic (RF) safety Clinical validation certificates from independent third parties Certificates or evidence to support efficacy claims and details of such experiments using air disinfectants for a particular microorganism should be shared with consumers.

B. Approvals: Clinical validation certificates from independent third parties such as US-FDA, CE, ISO, UL, OHSHA would allow users to make an informed decision on their air disinfection options.

C. Technology: The technology used should ideally destroy germs [bacteria, viruses, fungi and their spores] present in the air, eliminate VOCs (Volatile Organic Compounds and Chemical Air Contaminants), odors and particulate matter (PM). It should be safe, quiet, hassle-free, and less irritable to humans.

The premises or area where the air is to be purified (i.e. viral load or bioburden in the room), the size of the room and the number and type of people, equipment and of equipment present in the room / premises where the air needs to be disinfected.
