As part of the CARES Capital Improvements, Raytown is adding bipolar ionization into City Hall’s existing HVAC system, including upgrading four existing units at the front entry/lobby. Simply put, bipolar ionization removes harmful particles from air in enclosed spaces helping to create a safer work environment and meeting space for the community. By improving indoor air quality, Raytown is working to create a safer environment and to take strides to minimize the impact of the pandemic.


  • Helps stop the spread of airborne bacteria and viruses, including coronavirus, in occupied and enclosed spaces.
  • Reduces odors, dust, and pollen.

When integrated with existing HVAC systems, bipolar ionization collects oxygen molecules from air and converts them into charged atoms that cluster around microparticles, to surround and deactivate potentially harmful airborne substances like mold, bacteria, allergens and viruses. In the process, breath droplets and dust particles known to transport viruses are enlarged and caught in filters. Bipolar ionization can reduce up to 99% of airborne contaminants.

In the US, bipolar ionization was first introduced in the 1970’s as a tool to help control bacterium or fungus in the food manufacturing industry, most commonly known to cause food poisoning and stomach flu infections when consumed. Bipolar ionization has been proven effective against viral infections such as SARS, norovirus and multiple influenza strains. Bipolar ionization is currently being used in airports, hospitals and most recently in the cruise industry.
