MANN+HUMMEL mobile room air purifiers against COVID-19 and more

Whether it's COVID-19 or classic influenza, indoor exposure poses a significant risk of infection. Especially in the cold season, when the action shifts indoors, infections occur with increasing frequency. Restaurants, offices, school classrooms - areas where many people come together in a small space - require particularly strong protection against airborne threats. Enclosed spaces need cleaner and virus-free air.

Mobile OurAir air purifiers from MANN+HUMMEL provide efficient, economical and sustainable protection against harmful aerosols that carry viruses, bacteria, allergens and fine dust within a room. Our solutions are suitable for all industrial, commercial and public spaces where there are either no HVAC systems or the current ones are inadequate. They have the flexibility to be used indoors, anywhere and anytime - provided there is a power connection.

Since 1941, we have been separating the useful from the harmful, and for more than 60 years we have stood for air filtration of cleanroom quality for hospitals and operating rooms. With our professional OurAir air purifiers, you can effectively reduce the risk of infection for your guests, customers and employees. 

Benefits and purpose: Why use an air purifier for COVID-19 and more

  • The proof of efficacy of our room air purifiers was confirmed in the test by the Karlsruhe Institute of Technology (KIT)
  • State-of-the-art HEPA H14* filters in the OurAir air purifiers remove more than 99.995% of viruses and other pollutants from the air (e.g. coronaviruses and their mutations)
  • Filtering of bacteria and free allergens (e.g. dust mites or pollen) in the air
  • Reduction of bad, organic odors, harmful gasses and smoke with the additional use of a MANN+HUMMEL activated carbon filter

*High Efficiency Particulate Air, according to DIN ISO 29463 and EN 1822

OurAir air purifier against Corona: Best possible protection and safety

In closed rooms, the risk of infection with viral diseases such as COVID-19 or influenza is particularly high. But it is not only coronaviruses and their mutations that constantly spread throughout the room. Bacteria, free allergens and particulate matter also represent significant threats: According to the WHO, 99% of the world's population breathes bad air.

The big problem with indoor air pollution is that even when employees, students or guests leave a room, harmful aerosols remain in the space. Frequent ventilation is only a limited solution: In the winter, energy expenditure is huge if cold air from outside has to be repeatedly warmed up. In cities, the air outside is also frequently polluted by car or industrial exhaust fumes and tire abrasion. 

In the countryside, by pollen or unpleasant odors from agriculture. Indoor air quality can be as poor as outdoor air quality. Not to mention, in many buildings, there may not even be enough cross-ventilation to reduce virus concentrations. Our highly effective OurAir mobile air purifiers reduce the risk of infection by filtering harmful pollutants, thereby providing a flexible, effective solution to COVID-19 and other airborne contaminants.

In the OurAir series, we offer three room air purifiers for different room sizes:

You can use multiple OurAir devices as modules in larger rooms. You can buy our air purifiers online here.

Rely on air purifiers with efficient virus filters and activated carbon filters

The mobile OurAir air purifiers are equipped with high-efficiency filters. HEPA H14 filters remove more than 99.995% of viruses, bacteria and other hazardous particles from the air.

An additional advantage is that you can equip your OurAir HEPA room air purifier with MANN+HUMMEL's pioneering OdorControl technology. In this activated carbon filter, a multifunctional, chemically impregnated layer of activated carbon significantly reduces harmful gasses, irritants and organic odors. In the mid-size and large room air purifiers, OurAir SQ 1750 and SQ 2500, the activated carbon filter can be used as a pre-filter for the HEPA H14 filter. Thanks to its particle layer ePM1 55 % (DIN EN 779: F7), it protects the HEPA filter from dust, hairs and pollen. For the OurAir SQ 500, there is a combi filter that combines HEPA H14 filtration with a highly efficient gas adsorption layer: It combines the best features of particle and harmful gas filtration, draws out viruses like COVID-19, and even fights bad odors

Best-in-class antiviral air purifiers against Corona: Efficacy tested and confirmed

The KIT has tested the MANN+HUMMEL air purifiers in a study. Their research demonstrated that the use of our mobile air purifier led to a significant reduction in aerosol concentration in a seminar room. The study showed a 50% reduction in the aerosol load after four minutes and a 90% reduction after 15 minutes. After another five minutes the curve drops towards zero. There is a further reduction of almost 100 %.
