UV technology eradicates COVID-19 virus from surfaces

06 January 2021

SWEDISH CLEANTECH company LightLab Sweden is introducing a new UVC disinfection technology called PureFize, proven to inactivate bacteria and viruses, among them SARS-CoV-2.

To test its effectiveness, LightLab Sweden partnered with SAES Group and the University of Siena, Italy. The study uses a prototype of a real consumer product and shows that PureFize can be used to inactivate any SARS-CoV-2 presence (>99.9999%) on items that consumers use every day. The results will be submitted to a scientific journal of public health.

The study was conducted by the University of Siena and will be submitted for publication in a peer reviewed journal of public health. The study shows that PureFize is effective in inactivating 99.9% of the SARS-CoV-2 virus in the samples in less than three minutes and 99.9999% in less than 10 minutes. This is the first time a scientific study has been conducted and published using a prototype of a real consumer product for UVC disinfection of surfaces.

A good result was obtained to inactivate SARS-CoV-2 by the tested prototype of a real consumer product. The PureFize UVC technology can play an important role in inactivating SARS-CoV-2 from objects in everyday life, says Professor Gabriele Messina, MD, associate professor in General and Applied Hygiene (Public Health), University of Siena, Italy.

The PureFize UVC disinfection technology is a completely new and sustainable technology developed by the Swedish cleantech company LightLab Sweden. It has been developed to utilise a wider and more effective wavelength spectrum to inactivate bacteria and viruses. The technology is said to be fast, effective and generates minimal thermal heating, making it energy efficient. It does not contain any mercury or chemicals and does not generate ozone.

Rune Torbjörnsen, CEO at LightLab Sweden, said: "I am very proud that we now can present PureFize. Many companies on the market state that their products inactivate SARS-CoV-2 from surfaces, but few have actually conducted scientific tests with their products.

"Scientific validation is something that is very important to us. The effectiveness of PureFize has now been validated by the University of Siena. PureFize makes it possible to bring UVC into everyday life in a safe and sustainable way. We aim to raise the standard for UVC disinfection and show that PureFize can be effective in inactivating bacteria and viruses but also sustainable in minimizing the impact of the technology on the environment."

The technology is now being extensively launched and is ready to be shipped globally. The technology offers vast integration opportunities and can be used in a wide range of applications and installed in products without major redesigns or adaptations. LightLab Sweden has several ongoing projects with partners who want to integrate effective and sustainable UVC solutions into their products to provide added value to customers and consumers. PureFize is protected by 96 granted patents and another 47 patent applications are awaiting approval.

Fredrik Forssell, CMO, LightLab Sweden, said: "This is just the first step for us in raising the bar on disinfection through UVC technology and proving that the PureFize technology is effective on bacteria and viruses. We will continue to explore the many possibilities to apply this technology to secure a healthier and safer everyday life."
