img FAQ

The UV radiation can be classified into three types according to their wavelength (UVA, UVB and UVC). These UV wavelengths differ in their biological activity and the extent to which they penetrate inside cells and microorganisms. Out of these three, UVC has the highest disinfectant capacity because of its shorter wavelength and ability of this wavelength to interact with the RNA and DNA of the cells and microbes. Upon exposing COVID-19 virus to UVC light, it penetrates the virus shell and reaches its RNA strand. The rays are absorbed by (nucleotides) of virus RNA and cause photochemical fusion of two adjacent nucleotides.This process permanently changes the structure of virus RNA rendering it incapable of infecting any live cell. Thus, preventing chances of further infection.
The ‘Suraksha’ Virus Wiper is a device that disinfects virus and bacteria.
The method by which a UVC light renders a virus inactive is as following: -

Upon exposing a virus to UV light, the UV light penetrates the virus shell and reaches to the virus RNA or DNA. A virus RNA or DNA is like a long-stretched rope with ladder steps on it. These ladders are called nucleotides. UV light of a particular dose causes photochemical fusion of two nucleotides which are close to each other. This photochemical fusion is like chemically welding of nucleotides which permanently damages the RNA or DNA of the virus and hence renders them inactive. We can look to previous coronaviruses, such as SARS and MERS, for insight. Studies on both SARS and MERS show that UV light could render these viruses inactive. To inactivate viruses using UV light two key aspects are important. 1. Selection of appropriate UV light wavelength to which a virus is susceptible 2. Generating appropriate UV light exposure such that it causes the necessary damage to the genetic material (DNA or RNA) of a virus. A team at the university of Nebraska Medical Center recently evaluated Ultraviolet Germicidal Irradiation (UVGI) and its effect on Decontamination and Reuse of N95 Filtering Facepiece Respirators where they reported literature references supporting that UVGI exposures of 1 J/cm2 are capable of decontaminating influenza virus on N95 FFRs and exposures as low as of 2-5 mJ/cm2 are capable inactivating viruses on surfaces. The Nebraska Medical Center evaluated UVGI exposure in the range of 60 mJ/cm2 to 300 mJ/cm2 and reported that UVGI exposures were validated to reduce 6 log of bacterial and viral surrogate organisms. US FDA and NIH also investigated these two aspects of UV light on inactivating virus called the SARS-CoV1 virus. In short, the FDA and NIH study showed that UV light with a wavelength of 254 nm could create enough damage to the RNA of virus (SARS-CoV1) rendering the virus inactive. Both viruses have similar genetic molecules (RNA) and has approximately same size, shape and outer covering shell making them susceptible to similar damage profile caused by UVC light. Different viruses are sensitive to different UV exposure which were extensively detailed by Kowalski et al . Also a study by Cornell Medicine of Cornell University Scientists et al states an average of 67 J/m2 and maximum of 241 J/m2 dose of UVC to inactivate Corona Family Viruses.
‘Suraksha’ Virus Wiper is specifically designed and calibrated as per the FDA and NIH research paper mentioned above to deliver the recommended UVC wavelength and the recommended UVC dose per cm2 on the surface of an object placed inside the device. Moreover, ‘Suraksha’ Virus Wiper’s unique illumination design ensures that each point on the surface of an object placed inside the ‘Suraksha’ Virus Wiper receives the required wavelength and the required UV dose without generation of a shadow area. Most UV boxes in market, in saloons and in hospitals were designed for broad spectrum UV light and not specifically for delivering 254 nm UVC. Moreover, UV light placement in such boxes does not have reflector. This leads to generation of shadow areas on objects placed inside these boxes which leaves patches of unexposed surfaces making such UV boxes unsuitable for decontaminating all surfaces at the same time. Also, such commercial boxes are not calibrated to deliver the UV light dose as per the FDA and NIH research paper mentioned above, making them highly ineffective in inactivating Coronaviruses.
‘Suraksha’ Virus Wiper is made up of UV-C safe materials which not only ensure safe operations of the equipment but also ensures UV-C blockage to ensure that outside personnel do not get affected with the UV-C light. For example, the UVC doesn't start till the chamber is closed which is made sure using the right switches. Also, the internal surface of the chamber is completely reflective and the main body is made-up of UV blocking material to make sure safety for operator.
Yes, ‘Suraksha’ Virus Wiper can be used for masks, eye shields and other PPE that can be put inside the ‘Suraksha’ Virus Wiper. Published data on 15 different N95 masks treated with UV-C confirmed that UV-C light could effectively decontaminate virus infection on N95 masks. A team of scientists from the US evaluated impact of UV-C On decontaminating 15 different models of N95 models contaminated with H1N1 influenza. Their results showed significant reductions (≥3 log) in influenza viability from the tested N95 masks after treatment with UV-C light clearly establishing the ground work that N95 masks can be disinfected with UV-C light irradiation. Their data suggested clearly that N95 Mask decontamination and reuse using UV-C can be an effective method.
A general N95 respiratory mask comprises of four layers of material: Layer 1: Outer layer of spun-bond polypropylene Layer 2: Cellulose/polyester Layer 3: Melt-blown polypropylene filter material Layer 4: Spun-bound polypropylene. A team of scientist from Centers for Disease Control and Prevention CDC (USA) published a detailed scientific paper in 2015 in the journal of Occupational and Environmental Hygiene [8] where they evaluated effects of UV radiation on four models of N95 mask. The team exposed both sides of material coupons and respirator straps from the four N95 masks to UV-C doses from 120–950 J/cm2. The CDC team tested the particle penetration, flow resistance, and bursting strengths of the individual respirator coupon layers, and the breaking strength of the respirator straps to UV-C doses of 120–950 J/cm2. Summary of results obtained by CDC team on effect of UV radiation of N95 masks structure and stability. The CDC team clearly showed that UV exposure led to a small increase in particle penetration (up to 1.25%) at high UV dosage and had little effect on the flow resistance. The team also showed that at high UV dose the strength of the layers of respirator material was reduced. Such reduction in strength was directly proportional to the UV dose used.
Healthcare workers and support staff are working in close proximity with COVID-19 infected patients and Corona virus infected surface. ‘Suraksha’ Virus Wiper would play a pivotal role in reducing surface to human infection in such settings by decontaminating and sterilizing PPE for reuse by healthcare teams. Since most PPE such as masks, eye wear is in severe shortage, ‘Suraksha’ Virus Wiper could provide a viable option for quick sterilization and reuse of such PPE and lower the pressure on PPE inventory. ‘Suraksha’ Virus Wiper can also be used for flash sterilization of medical equipment and parts which are reusable inventory such as intubation tube etc. to prevent surface to human transmission.
‘Suraksha’ Virus Wiper has also been designed with the home user in mind. Groceries and other house supplies can be kept in ‘Suraksha’ Virus Wiper for UV decontamination cycles. In 2015 FDA approved the use of UVC light in the processing of fruit juices to reduce the microbial load. In food industry UV-C is already being used to decontaminate food and increase the shelf life by eliminating surface microorganisms. Users can use ‘Suraksha’ Virus Wiper for decontaminating milk packets, groceries, everyday vegetables, fruits, kitchen utensils, water bottles, baby milk bottles, toys, keys, TV remote, clothes, slippers and any day to day items. ‘Suraksha’ Virus Wiper works on multiple surfaces such as plastic, paper, metal, leather and fabric making it a versatile, nonchemical disinfection system.
UVC light has very limited penetration and cannot penetrate opaque, solid objects and hence can be effective in sanitizing food item surfaces. Treatment with UV-C light offers several advantages for food sanitization as it does not leave any residue chemicals in treated food, it is easy to use and lethal to most types of microorganisms.
Yes, electronic devices can be disinfected.
No, it may cause structural changes in the medicines which may alter the drug composition. We do not recommend use of ‘Suraksha’ Virus Wiper for sterilizing medicines.
A treatment duration of 10 minutes shall be sufficient enough to sanitize and disinfect the surfaces properly. However, it depends on the object being placed for disinfection.
Cleaning is generally not required after every usage but the whole chamber should be cleaned every month to clean the dust deposited over the surfaces and lamps in order to improve the lifespan of UV lamps.
UVC rays are very harmful to eyes and skin.It will affect the cornea and also cause itching in the skin.It is strictly to be used under adult supervision and should avoid contact with eyes and skin
The lamp life claimed by OSRAM/PHILIPS is 11000 hour
