FEATURES:
The Dual Filter™ is a combination of HEPA 14 and an activated carbon filter.
The HEPA part of the H14 filters fine dust, pollen, viruses and bacteria from the air.
The activated carbon filter binds gases (bad odours, tobacco smoke, formaldehyde, toluene, volatile organic compounds, etc.).
Compared to the H12 HEPA filter, the H14 HEPA filter has a higher density, so it can filter more particles out of the air.
ROGER BIG requires 2 x Dual Filter™ H14 HEPA.
The Dual Filter should be replaced every 8-12 months.
Filter efficiency: 99.995%.
TECHNICAL DATA:
MAXIMUM EFFICIENCY VIRUS FILTRATION WITH H14 HEPA FILTER!
According to the results of the independent British test laboratory AIRMID, Stadler Form ROGER air purifiers for home use are among the world leaders in proven excellent efficiency in filtering out corona viruses!
Test results have shown that live SARS-CoV-2 viruses* - the causative agent of COVID-19 infection - can be filtered out of the air by the ROGER Little and ROGER models at 99.3% in less than 1 hour. The ROGER Big model achieved an outstanding 99.9% filtration efficiency against SARS-CoV-2 viruses.
Consequently, our Stadler Form air purifiers are a huge help in reducing the risk of viral infections. They provide the best possible protection against coronavirus infection in enclosed spaces for family members and others. So it is safe to say that the product also filters the COVID-19 virus, as it is well above the size of the virus tested in the laboratory.
*According to the test results carried out in the UK by the AIRMID independent testing laboratory. A 28.5 cubic metre test chamber was used to test the air purifiers over a 60-minute period. The MS2 virus used for the tests has similar properties to the SARS-CoV-2 virus, both carrying genetic information in the form of single-stranded ribonucleic acid. Their adhesion properties to airborne particles are similar to those of viruses that are dangerous to humans, and they behave in the same way in terms of viability and resistance to disinfection. For this reason, the MS2 virus is often used to induce viruses of the same size for testing air purification equipment. However, the MS2 virus, which is approximately 25 nanometres in diameter, is barely a quarter of the size of the 120 nanometre SARS-CoV-2 virus. Measurements with smaller MS2 viruses show, based on virus counts, that ROGER air purifiers also reduce the number of much larger SARS-CoV-2 viruses to at least the same extent as MS2 virus counts.
