Airocide - Space Technology In Your Home

PCO Technology - An Overview

  • PCO = Photocatalytic Oxidation – developed more than 30 years ago.
  • Most effective scientifically proven technology for killing viruses both in the air and on surfaces (backed by hundreds of peer-reviewed publications).
  • Proven to kill many viruses, bacteria, volatile organic compounds (VOCs), molds, fungus, and odors wherever they reside.
  • Proven both safe and effective in laboratory and industrial testing – no potentially harmful health effects. 

PCO Technology - In Airocide

This NASA-developed Airocide technology employs a patented reaction chamber packed with tiny hollow glass rods coated with a proprietary solution of titanium dioxide (TiO2) permanently fused to their surfaces.

This technology is listed by FDA as a Class II medical device.

Photocatalytic Oxidation Chamber

When excited by high-intensity 253.7 nanometer lamps, this highly reactive catalyst becomes energized, producing 3.2-volt electrons that split water molecules every microsecond, producing trillions of surface-bound (OH-) hydroxyl radicals. Any solid or gaseous organic (regardless of size) that contacts these surface-bound radicals is instantly oxidized.


PCO Technology - Safety

  • Photocatalysis is a natural chemical process that breaks down organic molecules into carbon dioxide and water vapor.
  • Titanium dioxide is the most widely used photocatalyst because it is inexpensive, nonhazardous, and chemically inert.
  • Controlled output of specific ions are produced on demand.
  • Production of undesirable byproducts, such as ozone, is minimized .
  • It is well known that the release of any metal nanoparticles into the environment is a major health concern for any living organism in the environment, including animals and humans. TiO2 is bound within the unit and kept from escaping into the airstream through proper reactor design and coating process.
  • UV light is entrapped within the reaction chamber itself. Any light escaping through the top or bottom has been reflected and diffused to the point that it is not a hazard to humans. 

PCO Technology - What We Know

  • Over 7,000 peer-reviewed articles on PCO (many scientifically proven applications).
  • First articles published back in the 1970s, with many highly cited articles.
  • Over 2,000 refined applications using titanium dioxide. 

Airocide Clinical Studies Brief

Airocide is air purification that works. Three separate clinical studies found the following:

  • Achieved a 300% reduction in airborne microbes.
  • Generated no Ozone.
  • Eliminated mycotoxins (100 times smaller than viruses).
  • Found to be superior to the HEPA HVAC surgical air systems alone currently being used in hospitals.
  • Eliminated VOCs (volatile organic compounds) in test after test. 

Airocide Case Studies Brief

However, Airocide did not rest on the evidence from the Clinical University Studies; they took the next step. They took the technology to some of the toughest real-world environments that could be found and once again put it to the test.

These case studies demonstrated that the technology is truly revolutionary as follows:

  • Surgery – Average results 73% reduction in bacteria and mold.
  • Office – Average results 72% reduction in bacteria and mold.
  • Households – Average results 75% reduction in bacteria and mold.
  • Childcare Center – Average results 60% reduction in bacteria and mold.
  • Dental Private Practices – Average results 81% reduction in bacteria and mold.

Texas A&M University Studies

The airborne microbial destruction efficiency of the Airocide Photocatalytic Air Purifying System was studied by the Medical Microbiology & Immunology and Biomedical Engineering Departments of Texas A&M University.

Samples of unique clinical interest such as methicillin-resistant Staphylococcus aureus (MRSA) were studied in depth. The test results showed bacteria reductions of 69% in an Ear, Nose & Throat (ENT) Day Surgery procedure room, 25% in a Surgical Operating Room (OR), and 95% in the Surgical Instrument Sterile Preparation Room. MRSA was present in the OR and reduced by 100% after the use of the Airocide system.

The study reported that the PCR2 (Photocatalytic Reactor) biocide unit produced dramatic evidence of its effectiveness: a 300% reduction of airborne microbes. “The NASA technology proved superior to HEPA HVAC surgical air systems…” The unit was tested at the University in four clinical settings. The study concluded that it ‘…has advantages that are not possible with the best HVAC (heating, ventilation, and air-conditioning) high-efficiency filter systems.”

The researchers found the following advantages:

  • The high elimination rate of disease-causing microorganisms.
  • Eliminates volatile organic chemicals and bioaerosols (odors).
  • No ozone emissions.
  • Energy-efficient with low maintenance and long product life.

University of Washington Studies

Clinical Study at University of Wisconsin Environmental Chemistry & Technology Program Researchers tested and analyzed the unit's effluent and determined that the Ozone was undetectable. Analysis of the data also revealed VOCs (volatile organic compounds) were found to be in the very low parts-per-billion range.

Further laboratory tests conducted at the University also revealed that the technology employed in Airocide produces a 99.9937% kill of CFUs. This inactivation level overwhelmingly meets the definition of ‘sanitization’ as established by the Environmental Protection Agency (EPA) and the Association of Official Analytical Chemists, which requires that a non-product contact surface have a contamination reduction of 99.9%.

Texas Tech Studies

Clinical Study Texas Tech University Health Sciences Center School of Medicine Department of Microbiology and Immunology The technology was tested to determine its abilities to inactivate fungal conidia and mycotoxins. Under selected experimental parameters, the device could inactivate the tested mycotoxin Roridin A and the fungal species, Aspergillus Niger.
