• the halō kills airborne Covid-19 viruses, all known coronaviruses, and other pathogens in seconds and clears the air in under 5 minutes for indoor spaces up to 4,500 square feet (larger areas accommodated with multiple units). Our patent-pending technology minimizes the risk of airborne contagion while the halō is in operation.
• the halō draws air out of the breathing zone and into our unique low-UVC light ring, quickly disinfects the air, and returns cleaned air back to the breathing zone. Without the halō, invisible pathogens like the Covid-19 virus can stay in the air for hours, and the CDC and international organizations have identified tiny respiratory droplets as the primary pathway for disease transmission.
• the halō delivers a low-UVC disinfection dose optimized with our proprietary algorithm and based on our Boston University Medical School research, and achieves a 99.9% kill effectiveness for the Covid-19 virus.

• Our unique product quickly removes infectious air directly from the room’s breathing zone at 2,000 cubic feet per minute, kills 99.9% of germs in that air, and returns the disinfected air back to the breathing zone.
• the halō is much faster, cheaper to operate, and produces less of a carbon footprint than using HVAC to produce sufficient air changes per hour to flush out the infectious air.
• the halō is the only system that treats your indoor air safely and effectively while people are present. It’s novel removal & recirculation system is more effective than any HVAC, portable, ceiling-based, or ionization products available in the marketplace. The system is quiet and unnoticeable, except for its beauty!
• the halō Model 5R/M serves areas 500-1,000 square feet; larger spaces are easily accommodated with multiple systems. LUV Systems is currently developing models for smaller spaces, such as elevators, waiting rooms, and hallways.
• the halō increases employee productivity, decreases business disruption and sick days, and protects guest and employee health. We can protect the most vulnerable and resume normal operations by virtually eliminating the risk of cross-infections where people congregate, live, work or play.

No. Here are the various methods employed in the marketplace and some of their shortcomings, also summarized in our Indoor Air Disinfection Comparison Matrix.

• Central Heating/Cooling Systems (HVAC)
  • HVAC systems have wall or ceiling intakes, which do not eliminate airborne pathogens in rooms.
    • Wall intakes mean untreated air remains in the breathing zone longer.
    • Ceiling intakes have insufficient aerodynamic range and do not effectively disinfect the breathing zone.
  • HVAC systems often create hot and cold pockets in offices and rooms, where air remains stagnant – these areas can be hotbeds for infectious air.
  • HVAC systems may add ionization, chemicals, radio-frequency waves, ozone, HEPA filters, activated carbon, and UVC lights, but for the reasons mentioned above, even with these extra measures, there are no studies that prove HVAC systems to be effective in preventing person-to-person transmission.
• Portable Air Purifiers
  • Portable devices are designed for local air purification, which do not eliminate airborne pathogens in rooms.
    • Portable designs have insufficient flow to effectively treat breathing zone air, and are ineffective when people move around.
    • Unidirectional, low air flow doesn’t effectively clear the breathing zone.
  • Portable devices may use ionization, chemicals, radio-frequency waves, ozone, HEPA filters, activated carbon, and UVC lights, but for the reasons mentioned above, even with these extra measures, there are no studies that prove portable air purifiers to be effective in preventing person-to-person transmission.
• Ceiling-Based Systems
  • Ceiling-based systems, such as troffers, ceiling fans, and other upper air disinfection units are used to disinfect upper room air, but only the halō beats the CDC’s published 15-minute guideline and effectively prevents airborne pathogens in rooms.
    • Standard ceiling fans blow air downward, which mixes treated and untreated air in the breathing zone of a room.
    • Even ceiling fans equipped with UVC lights or LEDs have insufficient exposure times to effectively kill pathogens.
    • Other upper air units have low or no active air flow and don’t effectively clear the breathing zone.
  • Ceiling-based systems may use fans with added disinfection methods, but for the reasons mentioned above, only the halō effectively prevents person-to-person transmission.

the halō’s next-level design offers incomparable protection against respiratory pathogens including the Covid-19 virus. the halō combines three unique design elements:

• Effective capture of exhaled air with an upflow fan, within seconds and from the middle of the ceiling – designed with the ideal location especially due to natural warm loft of exhaled breath, and based on a measured “cone of influence” in the breathing zone of a room, with linear air velocities towards the halō that are gentle yet effective to capture respiratory aerosols
• Effective disinfection in our optimized light ring, specifically proven to kill 99.9% of the Covid-19 virus – designed to deliver the optimal low-UVC dose
• Effective flow patterns for indoor room air with an aerodynamic cowling system – designed to maximize clean air flow back into the breathing zone

This combination of airflow control and effective air treatment simply establishes the halō as the best-in-class product to reduce indoor respiratory transmission – no one else even comes close!

Yes! Low-UVC technology has been used for decades to kill pathogens, including all previous coronaviruses. In June 2020, our Principal Investigator, Dr. Anthony Griffiths at the Boston University Medical School, was the first researcher worldwide to report results of Covid-19 virion inactivation with UVC. With LUV Systems Low-UVC technology and the halō light fixture, Dr. Griffiths’ lab has now demonstrated a Covid-19 virion kill effectiveness well over 99.9%.

Since Dr. Griffiths’ original study, additional global researchers have published results backing up and proving the effectiveness of low-UVC to kill the Covid-19 virus. We continue to work with Dr. Griffiths on advanced Covid-19 inactivation research, including his recent testing of the halō light fixtures to prove our 99.9% Covid-19 virion kill within seconds.

In addition, we have conducted extensive independent aerodynamic tests to optimize the halō’s unique upflow technology to provide a maximum “cone of influence,” with a fan that gently draws air in the breathing zone up and away from people and directs it through our proven low-UVC light ring, and returns clean air back into the room.

Independent third-party testing of the halō has verified that ambient UVC levels are far below all federal and state environmental and occupational standards, with a 10X safety margin. This means your business can operate with the security and knowledge that you are keeping your employees and customers safe.

Our lamps are certified to be ozone-free, and independent lab testing has verified that the halō does not generate ozone.
