- 01

What is UV-C?

UV-C is invisible light with a wavelength between 200nm and 280nm in wavelength. This light has special germicidal properties, which means that UV-C is capable of inactivating microorganisms such as bacteria, viruses, fungi, and mold. It has been used since 1910 in wastewater treatment, and since the 1920s and 30s for air and surface disinfection.

- 02

How does UV-C disinfection work?

UV-C damages the DNA and RNA of microorganisms and disrupts vital cellular functions, like replication, and prevents these microorganisms from infecting humans. The germicidal properties of UV-C have been studied, understood, and proven for over 100 years, and thousands of peer-reviewed studies proving efficacy have been published to date.

- 03

Is UV-C safe to use around people?

No. UV-C can cause skin and eye irritation if humans are exposed, so the Arc should only be used in unoccupied rooms. The R-Zero Arc has redundant safety mechanisms including a pre-cycle countdown to allow operators to leave the room safely before a cycle begins, and intrusion detection that automatically shuts the device down if a person enters the room during treatment.

- 04

Can UV-C penetrate glass?

No. UV-C cannot penetrate glass, so you can run a disinfection cycle in rooms that have windows without harming anyone or anything on the other side of the windows.

- 05

Is UV-C safe to use in the kitchen around food? Is it safe to eat food that’s been exposed to UV-C light?

Yes. Since UV-C is just light, it’s safe to use around food. No harmful chemicals or pesticides, just naturally occurring light. You can leave an apple out on the counter, treat the room, then eat the apple immediately afterwards without risk.

- 06

Where do I position R-Zero Arc?

We recommend that you locate the device centrally in the room that you’re treating. If there are large obstructions in the room that may cause shadowing, we recommend running two shorter (3-5 minute) cycles on either side of the obstruction for maximum efficacy. Our team of infection prevention specialists will help you determine positioning within your space as a part of the onboarding process.

- 07

How long does a R-Zero Arc cycle take?

The R-Zero Arc can destroy over 99.99% of pathogens in a 1,000 square foot space in about 7 minutes. Larger rooms take slightly longer, while smaller rooms like hotel rooms, bathrooms, and patient rooms in hospitals can be treated in less time, typically 3-5 minutes. However, the touch time required is about 2 minutes per cycle. While a cycle is running, operators can be productive, for example beginning manual disinfection of the next space.

- 08

How many R-Zero Arc devices do I need for my space?

The R-Zero Arc is built to fit seamlessly into the existing operations of your organization. The size of your space, the desired frequency of disinfection, and your existing workflows can all inform the number of devices your team needs. Our sales team can provide recommendations tailored to your unique operational needs.

- 09

What kind of training does my team need?

Onboarding and training with R-Zero’s team of infection prevention specialists is included with every purchase. We will teach your team how to use the device safely and effectively, and also provide support and guidance to help you tell your employees and patrons that your space employs hospital-grade disinfection. These sessions will be scheduled after purchase of the device.

- 10

How often do the light bulbs need to be replaced for the R-Zero Arc?

The bulbs are rated for 16,000 hours, but your lease includes 1 full set of replacement bulbs per year – 8 bulbs for the device.

- 11

Does the R-Zero Arc produce ozone?

No. R-Zero uses bulbs with a special type of glass that blocks the transmission of the 185nm wavelength of light that typically creates ozone for other UV-C devices.

- 12

What pathogens does R-Zero’s UV-C device destroy?

UV-C has been proven to work on bacteria, viruses, fungi, and mold. So not only will the R-Zero Arc work on the toughest pathogens, including antibiotic-resistant strains, but it will also destroy fungi and mold and eliminate the unpleasant smells that typically accompany mold spores.

- 13

Is R-Zero Vive safe to run while the room is occupied?

Yes! R-Zero Vive uses a wavelength of 222nm which does not penetrate the outer layers of the eyes or skin so it’s safe to use in occupied and unoccupied rooms.

- 14

Does R-Zero Vive produce any harmful byproducts?

No! R-Zero Vive meets the UL 864 standard for ozone regulation and is designed to not produce any harmful levels of ozone or other VOCs.

- 15

How effective is R-Zero Vive?

R-Zero Vive kills 99.9% of pathogens in the air and on surfaces is as little as a few seconds.

- 16

How many devices do I need for my space?

R-Zero Vive works for 169 sq ft per device. Depending on the spaces you are covering you will need a different number of devices. A layered approach of R-Zero technology is the best-in-class for infection prevention.

- 17

How is R-Zero Vive installed?

R-Zero Vive is easily installed into existing 100-240 VAC lighting circuits.

- 18

How and when do I replace the bulbs?

Each bulb in R-Zero Vive will last over 1,000 hours of use, regardless of number of on/off cycles. A notification will be sent to the administrator dashboard when it’s time to replace them. Replacement bulbs are available through R-Zero customer service.

- 19

How do I turn R-Zero Vive on/off?

R-Zero Vive uses PIR sensors to turn on when a room is occupied so that it’s actively disinfecting as air and surfaces are contaminated. It also can be set through R-Zero Connect to be optimized in terms of energy and number of people using the room.

- 20

How long can I be exposed to R-Zero Vive?

The R-Zero Vive emits Far UV light which doesn’t penetrate the outer layers or skin or eyes, so prolonged exposure is safe for humans. The ACGIH has proposed a threshold limit value (TLV) for humans of 500mj/cm2 over an 8 hour day, and the R-Zero Vive irradiates less than 10% of that, well below the proposed TLV.

- 21

Is R-Zero Beam safe to run while the room is occupied?

Yes! R-Zero Beam has been designed to keep occupants safe from the powerful UV over their heads. The UV level is maintained below established exposure limits. Safety information can be monitored through R-Zero Connect.

- 22

Does R-Zero Beam produce any harmful byproducts?

No. R-Zero Beam harnesses the power of UV light to disinfect and uses no chemicals. It produces no Ozone. Additionally, there is no need for potentially hazardous filter changes.

- 23

How effective is R-Zero Beam?

R-Zero Beam can reduce airborne pathogen load in a well-mixed room by up to 99.9% in minutes. This is equivalent to replacing the air in the room with fresh air 12-16 times per hour. It is effective against a variety of common bacteria and viruses, including SARS-CoV-2.

- 24

How many devices do I need for my space?

R-Zero’s Beam coverage area is 500 ft2. R-Zero’s team of experts will help determine the layout and positioning that is right for your space, optimizing safety and efficacy.

- 25

How is R-Zero Beam installed?

R-Zero Beam is designed to be easily installed to the wall or ceiling. It can be installed directly into 120-240 VAC wiring. R-Zero leverages a network of trained installers, ensuring that when the installers leave, the system is live.

- 26

How do I turn R-Zero Beam on and off?

R-Zero Beam employs a PIR sensor to monitor the room and turn the device on automatically when anyone enters. The fixture then turns off after occupants leave the room, enabling maximum efficiency. Alternatively, R-Zero Beam can be operated via R-Zero Connect.
