PCO TECHNOLOGY

INFORMATION DATABASE

Our products employ a proprietary enhancement to the established photocatalytic oxidation (PCO) technology developed more than 20 years ago. This advanced product: Active Photodynamic Oxidation Technology is the foundation of our instruments currently being used to disinfect indoor air and surfaces. PCO has been proven to kill many bacteria, viruses, volatile organic compounds (VOCs), molds, fungus and odors wherever they reside. This is in contrast to some air only purification systems dependent upon air flow passing through the unit or through filters. PCO technology has been proven both safe and effective in laboratory and industrial testing. PCO technology similar to that used in our products has been licensed for use in medical, food, military, residential, commercial, marine and hospital applications. They have been approved or registered by UL, ETL, FCC, TUV, CE and CSA. PCO is used by NASA on the International Space Station. The following is a summary of some of the peer reviewed testing and studies performed by third party independent labs and universities.

Breaking the Chain of Infection

PCO technology has been developed for use in hospitals and healthcare facilities to assist in their efforts to enhance the safety of the "environment of care" as defined by The Joint Commission (www.jointcommission.org). Its report, "Infection Prevention and Control Issues in the Environment of Care, 2nd edition (2009)," specifically addresses the impact of nosocomial (originating in the health care environment) infections and their spread, using the Center for Disease Control’s "chain of infection" model. This chain is composed of five links:

  1. pathogen
  2. reservoir (where pathogen lives and grows)
  3. portal of exit
  4. mode of transmission
  5. portal of entry and susceptible host, or uninfected person.

Breaking a single link in this chain stops the spread of infection.  The PCO technology actively breaks it at two points: both the disease-causing pathogen and the reservoir where it thrives.

Transferring this technology from the clinical setting to residential and commercial settings is—such as the technology itself—“a natural.”  For as the EPA states:

"The quality of indoor air inside offices, schools, and other workplaces is important not only for workers' comfort but also for their health. Poor indoor air quality (IAQ) has been tied to symptoms like headaches, fatigue, trouble concentrating, and irritation of the eyes, nose, throat and lungs."

Technology Close Up

Those requiring evidence-based proof before trusting a new technology will find it in our gas-phase air purification system.

The story begins in 1903 with scientist Niels Finsen. His research verified the naturally disruptive impact of 254 nm wavelength (ultraviolet or UV) light on RNA and DNA.  It also won him the Nobel Prize for Medicine.

Now, fast-forward that Nature-based finding some 55 years. A researcher began exploring ways to maximize the RNA/DNA disruption effect of UV light while overcoming the major limitation—that of the requirement for very close contact between the light wave and the target (see “Target Talk” graph below).  The successful system he discovered served as the catalyst for next-generation technology.

In fact, the technology serving as the foundation for our air purification products:

  • generates a process called active photocatalytic oxidation (PCO)
  • forms and releases large clusters of positively and negatively charged ions:  Multi-Clustered Ions (MCIs)
  • attacks microbes (bacteria, viruses, volatile organic compounds (VOCs), allergens, molds, and odors), wherever they exist in the indoor environment
  • continues to treat the environment with MCIs on a 7X24 basis
  • has been proven unequivocally by independent universities and laboratories on a global basis to be highly effective and safe
  • is at work in many clinical, commercial, and residential buildings, as well as on the International Space Station.

PCO technology has further enhanced the microbial-killing effectiveness and efficiency of the root technology by more than 50%.  Unlike other Indoor Air Quality (IAQ) Systems (i.e. HEPA filtration, Germicidal UV, UV Robots, Negative Ionizers, Ozonators), our PCO products destroy microbes in the air, on surfaces, and in crevices, on a continual basis, with a technology that is safe for humans and animals.

Target Talk: the limitations of UV only products

Niels Finsen’s research proved wavelength light can be used to disrupt RNA and DNA activity. The same studies, however, showed that the effectiveness degrades by the inverse square. Or, stated more simply, the farther the target DNA or RNA is from the light wave, the less it is affected.

Our gas-phase air purification systems eliminate the distance factor through its active air treatment technology. Air-borne microbials need not be within a few inches of the PCO air purifier to be destroyed.

In contrast, a single UX 105™ can treat all the air in an enclosed space up to 5000 square feet.
