The new Stadler Form Roger Little room air purifier for rooms up to 33 m2. The unit's built-in laser air quality sensor constantly monitors both dust content and unwanted odours, which it can react to in automatic mode, switching to higher power if necessary, to make the air in your home as pleasant and safe as possible as quickly as possible.
The indicator light on the front of the unit will glow blue when the air quality is good, orange when it is not ideal and red when it is particularly bad.
The new Sanitized® hygiene technology textile, washable pre-filter catches larger impurities such as hairs or dust mites. Because this filter is washable, it is easier to maintain than any previous model. The textile pre-filter stops larger dirt particles from entering the HEPA filter and prevents spores from settling in the filter. The filter, which uses Swiss technology, can be hand washed at 30°C for a minimum of 20 times. Under average use, it is recommended to wash the pre-filter every three months. For allergy sufferers, especially during the pollen season with more severe symptoms or in case of higher dust loads, it may be appropriate to wash the pre-filter up to once a month. The textile filter, as an accessory, can be replaced afterwards.
Since 1935, Sanitized® has proven its antimicrobial technology in many areas. The company's products can be found in many areas of life, from the chemical industry to building materials and clothing.
At the heart of the system is a large H12 quality dual HEPA filter with an integrated activated carbon insert. This HEPA filtration blocks not only fine dust but also pollen, bacteria and to some extent viruses. And the activated carbon filter traps unpleasant odours. In the same test, the Roger was also able to filter 99.9% of influenza viruses from the air. (The test was carried out in a 28m3 test chamber with H1N1, H2N2, H3N2 variants.)
Roger's filter system filtered out 100% of the 0.255 µm dust particles in the air in the TÜV test. This filter system is able to filter 99.9% of airborne influenza viruses in a 22m2 room.
The ROGER LITTLE has a capacity of 231 m3/h CADR*, which combined with outstanding filtration efficiency makes it the ideal solution for air purification in the home. The unit is recommended for rooms up to 33 m2 , which means three air changes per hour for the whole room.
*CADR: Clean Air Delivery Rate, measured according to AHAM standards.
Although ROGER LITTLE can filter a room of 33 m2 (with 3x air change per hour), for larger air purification needs, heavily polluted areas or for allergy sufferers, ROGER LITTLE is recommended for rooms of 20 m2, because in the latter case it can perform up to 5 air changes per hour.
The heart of the unit is the large HEPA (H12) filter with built-in activated carbon insert. This is what extracts fine dust, pollen, bacteria and viruses from the air passing through it. Thanks to this filter, the Roger is ECARF certified, which is particularly good news for allergy sufferers.
The combined filter binds a very large proportion of air pollutants during its operation, so it is recommended to replace it every 8-12 months.
Compared to the previous version of ROGER LITTLE
The current version of the ROGER LITTLE (from 2021) has the familiar Stadler Form elegance of the previous version. For the new ROGER LITTLE, the grille and the pre-filter of the previous version have been replaced by a textile pre-filter in anthracite/light grey, thus providing it with an integrated hygiene function.
MAXIMUM EFFICIENCY VIRUS FILTRATION WITH H14 HEPA FILTER!
According to the results of the AIRMID independent UK test laboratory, Stadler Form ROGER air purifiers for home use are among the world leaders in proven excellent efficiency in filtering out coronavirus!
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 for family members and others in enclosed spaces. 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.
