Our air purifier put to the test: safe air disinfection with proven efficacy 

Result: >99.99 % (>4 LOG) 

The goal of the study was to analyse how well the STERIBASE® Plus system inactivates coronavirus surrogates.

Two coronavirus surrogates were used: Phi6 and MS2 bacteriophages. Phi 6: Cystoviridae, lipid-enveloped virus, dsRNA, MW RNA approx. 13.5 kb, diameter 60-100 nm MS2: Leviviridae, no envelope, ssRNA, MW RNA approx. 4 kb, diameter 26 nm

Result: This study proved UVPE to be more effective than traditional UV-C systems by >3 LOG

The goal of the experiment was to show that traditional filters do not work against viruses and that viruses survive in air handling systems. According to studies, UV-C systems are an effective alternative.

Result: >99.9999 % (>6 LOG)

The goal of the study was to analyse how well the STERITUBE® inactivates influenza surrogates.

This used: Bacteriophage MS2 (strain DSM13767), host bacteria: E. coli TOP10F’ – Infection via F family pili: Leviviridae Structure/size: naked; diameter 250 A (icosahedral shape); diameter 25-27 nm

Genome: 1s-RNA; 4 genes on a 3569 nucleotide genome

Proteins: 180 envelope protein and 1 adsorption protein copies

Result: 3.6 log (99.98 %) reduction by VIROBUSTER® versus traditional air handling systems 

Viruses (coronavirus surrogate: bacteriophage MS2), which are introduced into an air handling system in aerosolisation studies, are still present in an infectious form in the supply airflow up to four hours later. The F5/F7 filter elements used in air handling systems are not able to retain viruses sufficiently. The integration of UV-C modules in the airflow can in part reduce viruses to below the diagnostic threshold.

Result: STERIBASE® is the only powerful solution in terms of space efficacy. 

The series of tests is used to verify the efficacy of individual devices in terms of a reduction in microbial count. The criteria measured were “air recirculation” (measurements in a hermetically sealed room with several cycles) and “single cycle”. Furthermore, as part of the series of tests, the aspiration capacity and air circulation of the test devices was also measured.

Result: Across the area as a whole, pathogens were reduced by 67% and mould spores by 84%. 

The objective of this prospective, multi-centre user observation was to establish the mechanism of action of STERIBASE® with regard to the elimination of active bacteria and mould in room air under practical conditions. VIROBUSTER®’s UVPE technology contributes to increased air purity, even for UV-stable pathogens. This user observation thus supports the importance of UV-C technology as a valuable tool for reducing microbial counts in room air.

Result: Zero emissions In this study, 12 testers assessed the odour emissions/room air quality of the VIROBUSTER® STERIBASE® 300 Plus. 

All testers were trained and met the DIN EN 13725 selection criteria with regard to the reference substance n-Butanol. Samples were taken from the outlet of the VIROBUSTER® device and tested for three parameters: odour concentration (as per DIN EN 13725), intensity and hedonics (rated as per VDI 3882).

Result: No presence of VOCs This study tested whether using the VIROBUSTER® system results in a change in the volatile organic compounds (VOCs) in room air, and whether additional VOCs are found as a result of the system. VOC is an umbrella term for carbon-containing (organic) substances that evaporate easily (volatile) or are already gaseous at low temperatures (e.g. room temperature).
