Independent Tests Show Senturion+ Viruend Adsorptive Filtration Material Eliminates 98.8% of SARS-CoV-2 Virus


Viruend™ filtration material has been proven to block and inactivate the SARS-CoV-2 virus with a 98.8% removal efficacy rate.

We are eager to partner with filtration companies to deploy this potentially life-saving medical countermeasure against the spread of COVID-19, its mutations, and future infectious viruses.

Senturion+ announced that its patented Viruend™ filtration material has been proven to block and inactivate the SARS-CoV-2 virus with a 98.8% removal efficacy rate. Scientists from the Battelle Memorial Institute, a private nonprofit applied science and technology laboratory, tested Viruend in a composited paper media against live SARS-CoV-2 and determined that it significantly exceeds the filtration capabilities of standard N95 masks.

Battelle evaluated the filtration efficacy of Senturion+ Viruend and reported it “achieved 98.8% removal of infectious SARS-CoV-2 as compared to 65.4% removal in a concurrent [Viruend] control filter.” The report further stated: “[Results] may indicate that the 1.4 to 1.6 log reduction of infectious virus achieved in the eluent samples (as compared to the control eluents) is the result of mechanical inactivation.”

By comparison, a University of Tokyo test of standard N95 masks against live SARS-CoV-2 concluded the masks blocked between 57% to 79% of the virus. Unlike the Battelle test, the study did not test inactivation of SARS-CoV-2.

Previous independent tests of Viruend against the MS2 and TMV viruses and E. coli bacteria reached 99.999% filtration efficiency, positioning it to increase the effectiveness of masks and air filters to block viruses and bacteria.

“Viruend can be a game-changer for manufacturers of masks, HEPA air filters, and other air-filtration material designed to protect against SARS-CoV-2 and other viruses,” said Senturion+ CEO Ted Liu. “Recent reports from the CDC and EPA identify airborne transmission of the SARS-CoV-2 virus as the most common route of spreading COVID-19. We are eager to partner with filtration companies to deploy this potentially life-saving medical countermeasure against the spread of COVID-19, its mutations, and future infectious viruses.”

According to the Battelle report, the 98.8% live virus removal efficiency corroborates a previous Viruend test conducted by researchers at Zhejiang University’s BSL-3 in Hangzhou, China. “The Battelle, Zhejiang University and Tokyo results are important because they tested filtration material against live SARS-CoV-2 virus, whereas other materials now in use only tested against salt particles to simulate the virus,” said Senturion+ Chief Scientist Liangjie Dong. “The finding of virus inactivation indicates in-situ decontamination.”

Senturion+ Viruend was initially developed to remove arsenic, lead, and other heavy metals from wastewater and groundwater, the effectiveness of which has been certified by the National Sanitation Foundation. Current applications include consumer drinking water filtration and mining effluence remediation, as well as viral absorption in respirators, PPE, and air filters.

Senturion+ is seeking strategic licensing, manufacturing, and distribution partners who can quickly scale solutions to meet the rising global demand for the multiple market applications that Viruend addresses.

About Senturion+ LLC

Senturion+ produces a filtration compound capable of filtering arsenic, heavy metals, bacteria, and viruses. This material can be embedded in many raw materials and complex systems to filter air, water, and gas. In 2005, while at the University of Hawaii, Liangjie Dong focused on solving widespread arsenic, lead, and other heavy-metal poisons in water in developing countries. Typical filtration solutions produce toxic sludge, utilize pressure requiring energy, or have high operating costs. Dong selected a natural, highly adsorptive mineral and developed Mesomaterial™, which features zero-valent, iron-coated ceramic granules with thousands of pores of six to 60 nanometers in size. This innovative combination of pores and zero-valent iron block and immobilize harmful pollutants as well as serve as the basis for a range of highly effective filtration materials. Since then, Dong and his team have continued to develop advanced materials that protect human health from waterborne and airborne poisons and pathogens.
