Additional questions to our large-room air purifier

We have designed the OurAir SQ 2500 with spacious workplaces in mind. From offices to canteens, schools to hotels, you need the best HEPA* air purifier for large rooms to ensure your staff, pupils, colleagues and customers stay safe from viruses and contaminants with corona filters. Here’s why we think our large-room air purifier is a must-have for your business:

  • A centralized air purifier like the OurAir SQ 2500 will remove virtually all trace – 99.995% – of COVID-19 and other viruses or harmful particulates from circulation. This avoids infection outbreaks, and keeps your staff healthy and your business operating

  • Fitted with a world-renowned HEPA H14* air purifier filter this unit undergoes strict tests in order to meet the required standards. This means you can rest assured your HEPA* filter will be durable, hard-wearing and effective

  • Smooth, quiet and energy efficient operation lets you get on with your work and means your customers or colleagues can enjoy the space

  • With additional activated-carbon prefilter to eliminate odors, NO2 and VOCs, keeping your environment optimally clean and pleasant

  • The sleek, minimalist design means it fits unobtrusively into your building


The following spaces would benefit from a large-room HEPA* air filter system: Offices, gyms, schools, restaurants, bars, largetreatment rooms, hotels, airports, sizeable waiting rooms, shopping centers, cafeterias, nightclubs, retail spaces and supermarkets.

Wherever there is a large room filled with workers, visitors or customers, you can be sure they are as safe as possible, thanks to the air purifier for large spaces filtering the air.

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

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

Over recent years many of us have become concerned about poor air quality caused by pollutants and allergens. We may have air purifiers in our homes to keep our family healthy. But now, with the COVID-19 pandemic, the issue of clean air has become even more pressing. Employers and public sector workplaces need to ensure their colleagues and customers are safe, and installing a large-room air purifier goes a long way to creating a virus-free workplace.

  • Our large-room air purifier fitted with a HEPA H14* filter will exchange the air in your space up to five times per hour in a room of 200m2 or less
  • Each time the air is filtered, damaging particulates and virus-carrying aerosols are removed and captured within the filter’s mesh
  • Clean air goes back into the room, and the cycle continues

With the OurAir SQ 2500 even a large workplace or school can have healthy, virus-free air. So you can have the peace of mind that you’ve truly created a safe space for everyone.
