Occupied Spaces

In occupied spaces, viruses can transmit from person to person via infectious airborne aerosols.

  • SARS-CoV-2 is airborne and spreads through viral aerosols.
  • Infectious viral aerosols can remain in the air for long periods of time: studies suggest SARS-CoV-2 can remain in the air for up to 16 hours which is why continuous effective air purification is recommended.
  • Effective air purification continuously cleans the air of virus keeping the airborne viral load low and mitigating transmission from person to person.
  • Indoor spaces such as classrooms, auditoriums, gymnasiums, locker rooms, dining areas, common areas, waiting rooms, offices, bathrooms, and elevators pose a high risk for airborne transmission. Indoor spaces that lack adequate ventilation pose a higher risk of airborne transmission.
  • Existing buildings are not built for infection control.

The CDC, FDA, EPA, ASHRAE and a panel of 239 scientists recommend germicidal UV-C as an effective virus mitigation technology. 

  • Germicidal UV air cleaning is an essential piece of maintaining a comprehensive hygiene protocol in occupied indoor spaces, and Bluezone products are highly effective at killing airborne viral loads. Air cleaning is often overlooked, but easily addressed using the Bluezone Model 450. The Bluezone Model 450 demonstrated a 99.9995% elimination of MS2 bacteriophage, the official SARS-CoV-2 surrogate. For the complete third party lab test, please read ARE Labs – Efficacy of the Bluezone device against aerosolized MS2 Virus.

Bluezone products are critical components of a comprehensive virus mitigation strategy in indoor occupied spaces. For more information and mounting options on the Bluezone Model 450, please visit our viral kill product page.


“At Middleton Family Medicine we continue to prioritize our patients and staff health and safety. We’ve used Bluezone air cleaners in our waiting room and COVID test room since March of 2020. We’re happy to add two Bluezone Model 450s that demonstrated a 99.9995% kill of airborne virus.”
