Everything you need to know

1. What is UV?

Ultraviolet is electromagnetic radiation with wavelength from 10nm to 400 nm, shorter than that of visible light but longer than X-rays. UV rays are invisible to most humans. UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the Sun.

2. What is UV-C?

Ultraviolet-C is part of the UV spectrum and has wavelength between 100nm and 280nm. It is also called as hard UV – it is short-wave and germicidal and is generally completely absorbed by the ozone layer and atmosphere.

3. Is UV-C harmful for humans?

The human skin and eyes are the most sensitive to damage by UV-C at 265-275nm. Prolonged exposure can cause adverse effects, leading up to skin cancer & cataracts in the eye.

4. How does Ultraviolet-C light kill pathogens (bacteria, viruses & fungi)?

Germicidal UV-C energy damages nucleic acids (DNA and RNA) of pathogens, thus preventing replication and leading to hastened death of virtually all bacteria and inactivation of all viruses—both DNA & RNA types.

5. In what scenarios is UV light used in disinfection?

UV is regularly used in sewage treatment, air purification, drinking water purification and food processing for disinfection. In the medical industry, UV-C has been used regularly for sanitizing hospital operation theatres, ICUs & other areas where extreme hygiene has to be maintained. In recent times, UV-C has been used in hospitals across USA & China in response to COVID19. There is plenty of supporting research published in internationally reputed journals and publications. Some of them are shared below:

6. Is ZeroVir safe for humans?

Yes, of course! ZeroVir uses multiple sensors (Passive InfraRed sensor) from reputed manufacturers that continuously keep scanning the environment for any human activity. As soon as any human presence is detected, the ZeroVir unit shuts down immediately within a second, so as to ensure that the accidental exposure is way below the permissible limits set by WHO and other international bodies.

7. Should ZeroVir be used on humans?

No. ZeroVir is NOT meant to be used on humans. It is specifically designed to NOT work when there are human beings around.

8. So, where can ZeroVir be used?

ZeroVir can be used in any of the following:

> Any office complex/shopping mall/corporate park – lifts, toilets, meeting rooms, storage room

> Hotels, Restaurants, Cafés – hotel rooms, wash-basins, lifts, toilets, waiting areas, lobbies

> Play-schools, Schools & Colleges – classrooms, labs, libraries, gyms, play areas, toilets, lifts

> Retail chains across jewelry, footwear, apparel stores – sanitizing items touched by customers, changing/trial rooms

> Hospitals, clinics, nursing homes – waiting rooms, doctor consultation rooms, ambulances

> Banks – ATM lobbies, sanitizing items across the branch counters (cash, cheques, other documents)

> In your home – sanitizing individual rooms or items (vegetables, e-commerce deliveries, newspapers, milk packets, mobile phones, wallets, car keys, …)

9. How to install ZeroVir?

It is very simple. ZeroVir is a plug and play unit. You just need to attach it to the ceiling or wall using two screws and plug it into the nearest power socket! In case if it is a portable variant, you just have to plug it into the nearest power socket. For the ceiling/wall mounted units, please ensure that the installation position is such that there is a line-of-sight to the maximum surface area, in that enclosed space.

10. What are the ZeroVir variants available?

ZeroVir is currently available in the following variants:

> Ceiling-mounted: to be installed at the center of any enclosed space

> Wall-mounted: to be installed on the wall at any end of the enclosed space

> Box: to sanitize any items

ZeroVir variants are available in different sizes & colors to suit your requirements and blends well with your décor.

11. What is the disinfection efficiency of ZeroVir?

If ZeroVir is used as per the recommended guidelines, it would clean up to 99% of pathogens in 20 minutes. Please note that this is for all exposed areas that have a direct line of sight to the ZeroVir unit. Even if there is no direct line of sight, it does sanitize with somewhat lesser efficiency because ZeroVir is a light-based solution. However, we recommend
