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

To make sure we can live up to our promises, our air purifiers are regularly tested by independent labs. The following studies prove that VIROBUSTER® technology is highly effective with 99.99% treatment rates for coronavirus (surrogates Phi6 and MS2), for example.

Our devices offer multiple benefits versus alternative products

1
Device efficacy

VIROBUSTER® devices offer proven efficacy of >99.99% against SARS-CoV2 surrogates (Phi6 and MS2 bacteriophages) in just one cycle.

2
Space efficacy

The combination of slow intake and a high output speed guarantees a reduction in microbial counts for the whole room - in just a few minutes.

3
Device comfort

The pedestal offers stability, and the fan it contains is extremely quiet given its air flow capacity. It can therefore be used long term, for example in offices, hospital rooms and bedrooms.

4
Safety & Sustainability

Our devices work solely on the basis of UV-C. This means there are no filters or hazardous additional technologies such as plasma (ozone) or ionisation, making it an emission-free solution that is safe for users and the environment.

5
Cost-effectiveness

As there are no filters that would require regular changing, maintenance is only required every 2-3 years. Its low maintenance costs make STERIBASE® the perfect choice.

Device efficacy

“Coronavirus surrogate inactivation rates after a single cycle of the VIROBUSTER® STERIBASE® Plus device”

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

“Analysis of the transmission of airborne viruses via air handling systems and development of disinfection measures”

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.

“Influenza (H1N1) surrogate inactivation rates after a single cycle of the VIROBUSTER® STERITUBE® device”

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

Transmission of viruses by air handling systems and inactivation by UV-C radiation

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.

Space efficacy

Comparison of UV-C air disinfection devices

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.

Establishing the micro-organism elimination rate in room air using UV-C radiation

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.

Safety & Sustainability

Emission Values Test Report

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).

Impact of VIROBUSTER® air handling system on room air quality

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).

Measurements were carried out by the company ebm-Papst, as it was not possible to measure sound pressure levels in-house as they were too low. 

  • Sound pressure level 150m³/h 36.5 dBA*
  • Sound power level 150m³/h 47.4 dBA*
