How does the halō keep people safe?

  • 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 1,000 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.

Why is the halō the best way to reduce infections in my public spaces?

  • the halō is the only system that beats the CDC’s published 15-minute gudeline. Our unique product quickly removes infectious air from the room and kills 99.9% of germs while in operation.
  • the halō is the only system that treats your indoor air safely and effectively while people are present. It employs a novel recirculation system that 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.

Are there other ways to achieve similar or more effective results?

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.

Why is the halō considered best-in-class?

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 establish the halō as the best-in-class product to reduce indoor respiratory transmission – no one else even comes close!

Does this technology work for the Covid-19 virus?

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.

Why is UVC light from the halō safe?

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 knowlege that you are keeping your employees and customers safe.

I’ve heard that UVC lights produce ozone – does the halō produce ozone?

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

How does the halō work?

the halō uses low-UVC light to safely and effectively kill the Covid-19 virus and germs in the air. With our unique, patent-pending cowling ring design, we never expose people (or pets!) to the low-UVC lights. the halō uses a ceiling fan (in upflow mode) to draw air up and into the cowling to kill pathogens with a low-UVC light ring. 99.9% of the Covid-19 virus is killed within seconds, and cleaned air returns to the breathing zone in your business.

When do I turn the halō on and off?

the halō is designed to continuously disinfect air when people are in your business. Simply turn on the wall switch and the halō motion detector is activated. the halō uses the motion detector to start the system when people are present in your business. It automatically shuts down 10 minutes after everyone leaves an area. The wall switch can be used to manually turn off the halō at any time.

How do my customers know the halō is protecting them?

Your purchase of the halō includes a display certificate to inform customers that your establishment's indoor air is protected by the halō. The certificate will have a validity of 12 months, and LUV Systems will renew certificates upon receipt of your documentation verifying inspection or maintenance.

Operationally, the spinning fan and an indicator light provide visual confirmation that the halō is functioning. In a dark room, your customers may see a faint blue-green corona around the halō.

Do the bulbs in the halō need to be replaced?

Yes. In addition to regular maintenance such as inspection and dusting, we recommend proactive bulb replacement to ensure continuous protection from the halo. The average bulb life is 9000 hours and may vary based on cycling and your specific use conditions.

Our LUV Systems-certified contractors offer an inexpensive and convenient maintenance program to provide all recommended servicing for a flat monthly fee. Our future Shop page will provide a list of LUV Systems-certified contractors serving Los Angeles and Orange counties.

What are operating and maintenance costs for the halō ?

the halō draws 600 W from a standard 15 A breaker – around $50/month (assuming 16 hours/day, 6 days/week, $0.20/kWh). Recommended maintenance for the halō includes regular inspection, and scheduled bulb replacement. We estimate the annual cost of maintenance by a qualified technician is approximately $800, inclusive of labor, bulb replacement, and inspection.

Is the halō covered by a warranty?

Yes! With proper use and maintenance, the halō is covered by a 12-month limited warranty. The warranty includes all non-consumable components, including electronics, mechanical parts, and structural components. Bulbs are excluded from the warranty, as we recommend changing bulbs proactively on a schedule rather than waiting until they burn out. Our warranty is provided here.

How big is the halō?

the halō Model 5R/M is designed for a 500-1,000 square foot area and a minimum ceiling height of 8.2 feet. the halō has a radius just under 4.5 feet and a height of 1.2 feet, with a 30-inch radius fan enclosed within. LUV Systems is developing smaller models for areas such as elevators, waiting rooms, and hallways.

What is the coverage area?

the halō Model 5R/M is designed for 500-1,000 square foot indoor spaces with room length and width of at least 18 feet. Multiple systems can operate as needed for larger areas. LUV Systems is developing models for smaller areas such as elevators, waiting rooms, and hallways.

What color is the halō?

the halō and fan blades are currently available in 4 exterior colors, and may be custom painted for a nominal price to match any color desired. The stock colors include Angelica (pure white), Ivory (alabaster), Taupe (beige), and Ash (dark grey). Please contact us for non-stock color requests.

Does the halō replace our current ceiling fan?

Yes - the halō is precisely designed to optimize air circulation, and replaces any existing ceiling fan. the halō’s fan is custom-configured to provide the optimal “cone of influence” for effective removal of air from the breathing zone and adequate air changes/hour, including positioning of the halō’s fan and air flow/revolutions.

Is the halō certified or tested by governmental agencies or independent labs?

When the halō models are available for delivery in California, the halō will be certified as an indoor air cleaner by the California Air Resources Board (CARB), and likewise for other select states that have similar regulatory programs. Independent testing for safety and efficacy will be conducted by Intertek (ANSI/UL 507 standard).

Exhaustive testing has been conducted for airflow, spectrometry, and Covid-19 virion kill rate by MIT, Caltech, and Boston University resources, respectively. All airflow measurements, virology testing and data analysis is conducted in compliance with federal laboratory standards for quality control, safety, and efficacy.

Will the local authorities allow me to reopen my business with the halō?

Yes! Many public health authorities such as Los Angeles and Orange counties have established reopening protocols that consider mitigation measures, such as the halō. We are working with these and other agencies to establish the halō as a preferred mitigation measure to allow faster and more complete reopening of businesses, including schools.

Does the halō disinfect surfaces?

Not directly. the halō is for disinfection of indoor air, which the CDC has identified as being the primary mode of transmission for the Covid-19 virus, as well as other airborne pathogens. By disinfecting the air, the halo will reduce the amount of virus that lands on surfaces. Along with installing the halō, we recommend continuing to follow surface disinfection guidelines published by the CDC.

Do we need to wear masks or social distance in a room with the halō?

the halō is a substantial mitigation measure to reduce respiratory transmission of Covid-19 virus and other pathogens. While our recommendation is to always follow CDC guidelines, we are working with CDC and local public health agencies to establish the halō as a preferred mitigation measure to relax mask and social distance guidance.

Is there any noise, vibration, odor, or noticeable wind when the halō operates?

the halō operates quietly and with no vibration, only the gentle turning of the fan. There is no odor or breeze – the halō feels like a typical room ventilation system, with the added benefit of no cool/hot zones because of our effective, directed air circulation. Unlike a traditional downflow ceiling fan, the halo does not blow air down onto people in your establishment.

Does the halō work with openings such as doors and windows?

Yes, the halō works in any indoor space, even with doors, open windows, or other sources of air currents such as HVAC systems, kitchen and bathroom vents, table fans, hair and hand dryers, vacuum cleaners, etc.

Does the halō impact my HVAC system?

Yes – in a good way! Because of the effective, directed air circulation created by the halō, hot and cool regions are eliminated, such as those often caused by HVAC systems. The temperature in a room feels balanced and comfortable.

the halō uses an upflow (reverse) fan that reduces thermal stratification of the air. As such, heating costs are reduced during cold months, and cooling costs are slightly increased during warm months.

Is the halō patented?

Yes, the halō is covered by numerous patent-pending utility and design applications. In addition, our parent company, EnviroProcess Consultants, holds various patents and patent-pending applications that use low-UVC light to safely and effectively capture and/or kill the Covid-19 virus and other germs.

What is the lead time for me to get the halō?

As of March 2021, our estimated order lead time is 10-14 weeks for the halō Model 5R/M, including final agency and independent testing laboratory certification. Please call or email us here for availability updates.

Can I install the halō myself?

As an electrical fixture that mounts to the ceiling in your establishment, the halō must be wired and installed by a qualified person or contractor. Our future Shop page will provide a list of LUV Systems-certified contractors serving Los Angeles and Orange counties.

How long does it take to install the halō?

Most installations of the halō are completed by two qualified persons (such as licensed electricians or general contractors) in less than 4 hours. Your actual time may vary based on site conditions such as power supply and access to the ceiling.

Can I lease or finance the halō?

Yes - we have established a financing partner that can provide attractive terms. Our future Shop page will provide further details.

Can I relocate the halō if I move my business?

Yes – if you are planning a move with your halō, please contact us and we will help with various options.
