Efficacy of MANN+HUMMEL mobile air purifiers scientifically confirmed
The Karlsruhe Institute of Technology (KIT) has tested the OurAir air purifiers for medium-sized and big rooms and has proven their effectiveness. By using a mobile air purifier from MANN+HUMMEL, the aerosol concentration in the room air is drastically reduced after only a few minutes and approaches zero in the further course. This means almost 100% less air pollution. The study confirms a significant reduction in harmful particles indoors - and, as a consequence, a reduced risk of infection.

Traditional heating and cooling or HVAC systems work through a process of evaporation, refrigeration and condensation to extract heat from the air inside a room and send cool air back in. To heat a room air is warmed by a furnace and distributed by the system until the space reaches the thermostat-regulated temperature. These ventilations systems may not also clean the air – or at least not from viruses and bacteria. Which is where an all-in-one unit like the OurAir SQ 2500 comes in.
- This HEPA H14* large-room air purifier captures particulates up to 0.1 μm
- An astonishing 99.995% of harmful microbes and virus droplets are removed, leaving clean air circulating back into the room
* according to ISO 29463 and EN 1822
It’s simple: for a big room you need a large area air purifier that can cope with the square meterage of the space. Look at the air purifier’s Clean Air Delivery Rate and measure your space accurately to make sure the air purifier can process the necessary amount of air per hour (m3/h).
- Larger rooms can happily house a more substantial central air cleaner, and will require an air purifier with a greater air flow rate. The air flow rate of an appliance means the number of times it changes the air – this is usually approximately six times the room volume per hour. So, with a room volume of 100m3 an air purifier will need to filter around 600m3 of air per hour.
- The air exchange rate refers to how often an air purifier circulates the air volume in the room per hour. Many air purifiers complete this at least twice per hour – but with a MANN+HUMMEL appliance you get an air exchange rate of five times per hour
- For rooms up to 200m2 the OurAir SQ 2500 is a great choice for your corona filtration strategy, and for even larger areas you can buy multiple units and spread them out
