New UV light disinfection technology proven to eradicate the SARS-CoV-2 virus (Covid-19) from surfaces in daily life

Today, 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
well-recognized peer reviewed international journal. 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 ten 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.


– We are happy to present the first scientific evidence of this UVC disinfection technology. A very 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. PureFize has been developed
to utilize a wider and more effective wavelength spectrum to inactivate bacteria and viruses. The
PureFize technology is fast, effective and generates minimal thermal heating, making it energy
efficient. It does not contain any mercury or chemicals and does not generate ozone.


– 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, says Rune Torbjörnsen, CEO at LightLab Sweden.


The PureFize 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.


– 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, says Fredrik Forssell, CMO, LightLab Sweden.

About the study:
The University of Siena has tested a new UVC technology called PureFize that is developed by LightLab Sweden. During the study the PureFize UVC light sources were placed in a surface disinfection box developed by LightLab Sweden for general demonstration purposes. Six PureFize light sources where used at a distance of > 7,5 cm from the Sars-Cov-2 samples. The sample was a solution containing SARS COV-2 at a concentration 107,2 *TCID50%/ml, where TCID50% means a virus concentration such as to induce damage on 50% of infected cells. The result was a reduction of 99.9% (log3) of the virus in the samples in less than three minutes and 99.9999% (log6) in less than ten minutes.


About PureFize®:
PureFize is a safe and effective technology to disinfect surfaces, foods, water and air. Using a world-leading proprietary nanotechnology PureFize creates a unique and broad UVC light spectrum where all bacteria and viruses, including SARS-CoV-2, are destroyed beyond repair with exceptionally high degrees of germicidal reduction. PureFize is energy efficient, sustainable, mercuryfree, or create any ozone and guarantees minimal thermal heating. PureFize is protected by 96 granted patents and another 47 patent applications are awaiting approval. The technology is developed by LightLab Sweden and designed with integration in mind for commercial and consumers applications and products.

About SAES Group:
A pioneer in the development of getter technology, the SAES® Group is the world leader in a variety of scientific and industrial applications where stringent vacuum conditions are required. In 80 years of activity, the Group’s getter solutions have been supporting technological innovation in the information display and lamp industries, in sophisticated high vacuum systems and in vacuum thermal insulation, in technologies spanning from large vacuum power tubes to miniaturized silicon-based microelectronic and micromechanical devices (MEMS). Starting in 2004, by leveraging the core competencies in special metallurgy and in the materials science, the SAES Group has expanded its business into the advanced material markets, in particular the market of shape memory alloys, a family of materials characterized by super elasticity and by the property of assuming predefined forms when subjected to heat treatment. These special alloys, which today are mainly applied in the biomedical sector, are also perfectly suited to the realization of actuator devices for the industrial sector (domotics, white goods industry, consumer electronics, automotive and luxury sector). More recently, SAES has expanded its business by developing a technological platform that integrates getter materials in a polymeric matrix. These products, initially developed for OLED displays, are currently used in new application sectors, among which implantable medical devices and solid-state diagnostics imaging. Among the new applications, the advanced food packaging is a significantly strategic one, in which SAES is offering a range of new products for sustainable packaging and aims to compete with fully recyclable and compostable solutions. A total production capacity distributed in ten facilities, a worldwide-based sale & service network and over 1,000 employees allow the Group to form a truly global enterprise.
