A new proactive way to reduce pathogens & infections

Studies have estimated that a third or more of U.S. schools have mold, dust, and other indoor air problems serious enough to provoke respiratory issues like asthma in students and teachers. Any environment where people frequently gather is susceptible to a number of microbial threats, and schools are no exception. Close interaction between students, lack of hand hygiene, and failure to suppress sneezes and coughs can all contribute to the spread of communicable illness.

Primary systems clean air technology is a proactive strategy for improving student, teacher, and staff health conditions. Indoor air affects more than health. A growing body of research suggests students also perform better in schools with healthier air. Norovirus been known to infect nearly one-third of teachers and students at school. Bacterial meningitis and Streptococcus spread quickly in close knit communities, and a classroom of children is susceptible, especially if proper hygiene standards are not maintained. Mold presents a particularly insidious threat, as it can worsen air quality and affect students and teachers predisposed to asthma and other respiratory illnesses. Deploy our solution in common areas such as gyms, cafeterias, nurse offices, and other spaces to reduce the risk of outbreaks, including: norovirus, rhinovirus, and bacterial infections. This results in fewer student sick days and lower cost-of-staff absences due to illness. 

Primary Systems will also provide validation services to confirm effectiveness after the solution is implemented within your facility. Validation process provides quantified results to support reporting, marketing, and risk management objectives.

Our Technology

  • UV-C Treatment– effectiveness limited to pathogens passing through UV-C emission; limited range and ineffective treating around shadows; not cost effective; UV bulb deteriorates; does not remove allergens from air; direct exposure to UV-C light is harmful to people; Over time, DNA/RNA can become resistant to UV-C treatment.
  • Chemicals– (hydrogen peroxide, bleach)- kill pathogens on surfaces; labor intensive to apply; not continuous; potentially corrosive to equipment; does not treat air.
  • HEPA Filtration– moderately effective on dust, pollen, mold spores; does not remove chemical fumes, smoke or odors; organisms captured in filter can breed or reproduce; does not kill pathogens.
  • Photocatalytic Oxidation– exposes UV light to a catalyst like titanium dioxide; requires UV light to operate; found to kill pathogens in a laboratory; not cost effective; killing effect limited to what passes through the device; can produce high levels of ozone.
  • Ionizers– built around a negative ion generator; removes particles from the air but not from the room (they settle on floors, walls, and furnishing and can be recirculated); produces ozone as a byproduct; does not remove odor; some can provide sterilization but only via high ozone levels.
  • Ozone– corrosive to equipment and surfaces: irritates throat and lungs; effective, but only at levels deemed hazardous by EPA.


  • Non-corrosive
  • Continuous operation without aggravating people
  • Tested effective against a large number of pathogens
  • Effective on surfaces, air & spaces (treating everywhere that the treated air touches)
  • Long lasting
  • Inexpensive operating costs
  • Kills pathogens
  • Removes VOC’s, odors, and smoke
  • Treats 100,000-150,000 cubic feet of air and surfaces
