Here are three methods to scrub the air using ultraviolet light. These can be applied as stand-alone or all three can be used for the same area you wish to protect from airborne pathogens of all kinds.
1 – Ionized hydrogen peroxide
What if there is a way to scrub the surfaces of tables, chairs, buses, etc. while also scrubbing the indoor climate of germs?
Ionized hydrogen peroxide (H2O2) is used in hospitals and public conveyances and it can be applied to any airconditioned indoor environment. This technical but simple solution is scalable from the largest convention center to the smallest home.
NOTE: H2O2 does not eliminate germs on either glass or aluminum surfaces.
REME® or Reflective Electro Magnetic Energy, is an advanced oxidation technology developed by RGF Environmental Group to minimize and neutralize indoor air pollutants such as bacteria, viruses, mold, gases (VOCs), odors, pollen, dust, and other airborne particles. REME® uses an electro magnetic energy cell to create ionized hydro-peroxides (H2O2), a friendly oxidizer plasma made from oxygen and humidity. This hydrogen peroxide vapor is excellent at killing germs, reducing VOCs and eliminating unwanted odors. In addition, RGF’s In-duct HVAC unit, the REME HALO®, has the added benefit of reducing airborne dust and particles through bi-polar ionization. Particles will clump together to form larger, heavier particles, which in turn drop out of the air or are caught by your filter.
Safety
“It is a normal reaction to question the long-term safety of any product that is effective and uses new or ‘breakthrough’ technology. This type of question has become common, as our litigious society has taught us to question things that significantly outperform existing methods or products.
There is no known case of hydro-peroxides ever creating a health risk. Considering we have been exposed to hydro-peroxides in nature since the day man stepped on the planet, it is a reasonable assumption that hydro-peroxides do not constitute a health risk. Over the past 20 plus years, RGF has more than four million Advanced Oxidation products successfully used worldwide without a safety problem.
The breakthrough in the RGF advanced oxidation technologies is a group of oxidants known as Hydro-peroxides. Hydro-peroxides have been a common part of our environment for over 3.5 billion years. Hydro-peroxides are created in our atmosphere whenever three components are present: Oxygen molecules, water vapor and energy (electro magnetic)
Ionized-hydro-peroxides are very effective at destroying harmful microbials in the air and on surfaces. As oxidants, they do this by either destroying the microbe through a process known as cell lysing or by changing its molecular structure and rendering it harmless (which is the case in VOCs and odors). The amount of hydro-peroxides required to accomplish this task in a conditioned space is well below the level that is constantly in our outside air. The Advanced Oxidation Technology found in RGF’s Guardian Air and REME product family has brought the oxidants found in the outside air into the conditioned space of your home.” RGF Environmental Group, Inc. | REME
RGF manufactures a range of products for installation in commercial air handling systems from 250 CFM (cubic feet per minute) to 100,080 CFM.
RGF also manufactures a range of products for residential air handling systems from 250 CFM to 18,000 CFM. These products purify the air in the entire home. The residential products also accommodate mini-split
Ultraviolet Light Sterilizers
CAUTION – Some Strategies to Kill the SARS-CoV-2 Virus May Be Creating Mutations
Can you put your hand into a flame and not be burned? Yes, you can. I don’t recommend an acetylene torch for this experiment; a regular household candle will do. Many of us have, at one time or another, swiftly passed a hand or finger through a candle flame. If done quickly, no burn; if done slowly, you will feel some pain.
For radiant energy to fully deactivate biological material, there must be sufficient intensity (high power level) and timely exposure to do the job. If either the energy level of UV light is too low or exposure time too short, instead of deactivating the SARS-CoV-2 virus, a mutant may be the product.
Follow the manufacturer’s instructions and over estimate the need for UV equipment to forestall the creation of a mutant monster that will surely come back to haunt you. For example, if the manufacturer of an upper-room sterilizer specifies effective distance as 70 feet, consider planning for 35 feet of coverage and carefully schedule routine service. My opinion.
UV lamps begin to deteriorate immediately upon first application of power. As it is with fluorescent lighting, switching power on and off shortens the life expectancy of the UV lamps. Seeing that familiar violet glow does not indicate the invisible UV light continues to be produced.
2 – UV Sterilizers for Air Handling Units
UV sterilizers are commonly used within air handling unit compartments to kill germs in condensate pans and simultaneously clean the downstream side of cooling coils to optimize energy efficiency.
Note: UV light breaks down non-UV rated wiring insulation and other non-UV rated materials. Check with the unit manufacturer before installing UV sterilizers.
There are also UV sterilizers overhead installation to kill airborne pathogens.
Manufacturers of UV sterilizers include RGF Environmental Group, Inc., Larson Electronics, InCharged, and others.
CAUTION: UVC products are deadly to germs and can be dangerous to humans. Consult your local wholesalers and vendors before purchasing these products.
Some manufacturers state their UV-C products are harmless to humans. If you elect UV products to which humans and pets will be exposed, get a written, signed statement from the vendor attesting to the safety of the products.
Although the H2O2 and UV sterilizers both employ ultraviolet radiation, they are not similar products.
3 – Upper Room UV Sterilizers
HOW UPPER—ROOM UV-C WORKS
“Typically installed on a wall at a height above seven-feet or above, the UV-C light fixture employs special louvers to direct the germicidal irradiation at an upward angle and outward to create an intense zone of UV-C in the upper-room while minimizing the dosage in the lower (occupied) portion of the area.
As convection or mechanical air currents lift communicable airborne agents into a room’s upper-region, they are exposed to the germicidal UV-C wavelength, which breaks the bacteria or virus DNA chain rendering it incapable of reproducing.
Because people generate many of the infectious airborne pathogens (which fall out or plate out onto equipment surfaces and floors) in a space, these upper-room systems are very effective at killing in-room, airborne microorganisms. Studies have shown that upper air UV-C units can translate to the equivalent of 10 to 16 ACH (air changes per hour).” UV Resources | Powerful Upper-Room Germicidal UV-C Fixture Kills Airborne Viruses and Bacteria
