If the air passing through the HEPA filter is pre-treated with electrically charged oxygen, all airborne viruses and bacteria will be neutralized, thereby eliminating their threat to human health.
HEPA stands for High Efficiency Particulate Air and is a filtration rating that captures microbes, dust, and particulates over 0.3 Microns in size.
The U.S. Department of Energy first coined the term “HEPA” as a filtering specification for suppliers of filtration products, based on how effective they were at particle removal.
HEPA filters consist of a complicated mix of filaments and fibers that carry a static charge which lures various microbes and particles like a magnet. While the particles travel through the air filtration system, they’re captured and retained within the filter.

How do viruses like COVID-19 spread through the air?

By nature, viruses are sub-micron in size, 500nm (0.5 micron) or less. Not to mention, only a small amount of any virus is all that is needed to enter your body in order to start an infection.The truth is, some viruses will inevitably pass through any HEPA filter. Here’s why…

Typically, viruses like COVID-19 or even H1N1 are spread through biological aerosols, tiny moisture droplets that are expelled whenever you sneeze or cough.

They carry bacteria and viruses through the air and ultimately your respiratory system. Over time, with enough untreated air volume or extended use, these tiny particles will eventually separate and penetrate the filter due to their sub-micron size.

So, can a HEPA air filtration system help lower the spread of the COVID-19 virus?
The short answer is YES, it can “help”, if all you are concerned about is air quality. On the other hand, what about the hard and soft surfaces in your live/work environment? What about the walls and flooring?

What about the carpeting, draperies and furniture fabrics? None of these items will pass through a HEPA filter, but they can all be an unchecked host environment for bacteria and viruses even if you are using the best air purifier on the market to clean the air in your live/work space!

HEPA air filters, on their own, are therefore limited as to the scope of their effectiveness, to airborne particulate only.

This powerful oxygen gas will sanitize and deodorize three thousand times faster than chlorine leaving no harmful residue. It will instantly attack chemical, organic and biological substances, breaking down their cell structure and molecular compounds, killing bacteria and viruses rendering them completely harmless BOTH in the air and on hard and soft surfaces.

The treatment equipment is a fully self-contained three-part system that can destroy any kind of odour or pathogen and strip out all airborne particulate from the air space in which it is used. In addition, this unique air treatment system can disinfect all hard surfaces, carpeting, drapes and furniture fabrics instantly on contact with high concentrations of electrically charged oxygen gas.

An adjustable timer can be pre-set to run the disinfection process for a specific period of time (i.e. 1 to 99 Hrs). During this cycle, a powerful air blower pulls the air in the room through a HEPA filtration chamber. The 16” HEPA filtration canisters, utilizing electrostatic attraction, are rated to remove up to 99.97% of all airborne particulate in excess of 0.3 microns in size.
During this stage of the treatment process, 90% pure oxygen gas is subjected to an electrical charge to turn it into a powerful disinfect with 3000 times more killing power than chlorine. The charged oxygen is released into the HEPA filtration chamber discharge air, which in turn is forced back into the room air space at 750 cubic feet per minute. The air turbulence created by the discharge blower will insure maximum distribution and penetration of the disinfection process throughout the live/work space.

At the end of the first timing cycle the oxygen supply is terminated and a second blower is activated doubling the air volume movement. During this stage, the air in the room is simultaneously circulated through an activated carbon charcoal air filtration canister as well as the HEPA filtration canister to convert the electrically charged oxygen back to normal air. The result is clean fresh air and a totally disinfected room and contents.

In homes or offices with a forced air HVAC system, the electrically charged oxygen gas is also fed into the main cold air return vent to insure the disinfection and deodorization of the entire air handling system’s interior duct work. Additional air movers insure every square inch comes in contact with the charged oxygen gas during the treatment cycle.
