The Covid-19 pandemic has changed the daily lives of residents all over the world. For fear of the virus and to limit its spread, restrictions had to be put in place including barrier gestures, curfews and closures of shops and restaurants. We wear masks, wash and sanitize our hands regularly, and ventilate the rooms in which we live. However, the doubt remains. Are not Covid-19 and other viruses present in the air when we are in a restaurant, in the waiting room of a doctor's office or in a classroom?
The filtration specialists of MANN + HUMMEL (Ludwigsburg, Germany) have developed effective methods and devices to reliably purify the air.
"Our antiviral air purifiers are able to safely filter more than 99,995% of viruses, bacteria and microorganisms present in the ambient air thanks to their HEPA H14 filters certified ISO 29463 and EN1822", eexplains Jan-Eric Raschke, Director of Air Solutions Systems at MANN + HUMMEL. “Our devices are compact and quiet, inexpensive to use and easy to maintain. "
"We are also able to fight against viruses by improving the ventilation and air conditioning systems already installed" says Frank Spehl, R&D director of the air filtration division of MANN + HUMMEL.
By equipping them with HEPA filters, heating, ventilation and air conditioning (HVAC) systems can contribute to a significant improvement in air quality without major intervention or increased energy costs.
Use of cleanroom technology
These advances are made possible thanks to MANN + HUMMEL's long experience in the field: for 80 years, its experts have separated the useful from the harmful with state-of-the-art filtration devices. First deployed in the automotive sector from 1941, these devices were successively extended to other fields. For example, for six decades, the Company has successfully provided air purification in the most sensitive environments such as clean rooms and operating theaters.
“We were able to draw on this valuable knowledge to develop our air purifiers. This allowed us to quickly bring these devices to the market: they have been successfully tested in the context of numerous scientific studies and are now available to our customers for simple and reliable use ”, says Mr Raschke.
This success is also explained by the choice to internalize the production of these filters:
“All the filters we install are produced and tested at our European production sites. Even if the term 'HEPA filter' is not protected, our customers can count on MANN + HUMMEL to provide them with excellent products: if our filters are HEPA labeled, we guarantee that they are of HEPA quality ”, says Mr Spehl. Whether the virus mutates or the Covid-19 pandemic abates, these filters will always be of great help. Indeed, even influenza viruses and pollen have no chance against them! Thanks to these filters, even people with allergies can breathe peacefully.
The products at a glance
Depending on the size of the room, three mobile air purification systems are available to provide healthier, virus-free air in virtually all types of interiors: the OurAir SQ 500 (for rooms measuring up to 40 square meters), OurAir TK 850 (for rooms up to 70 square meters) and OurAir SQ 2500 (for rooms up to 200 square meters). For particularly large rooms, several units can be placed in a modular fashion. Following the “plug-and-play” principle, the OurAirs immediately provide healthier air.
Each model in the range is equipped with a HEPA H14 filter that captures more than 99,995% of viruses, bacteria and other microorganisms in the air. These filters are individually tested to ensure the highest level of safety. Our air purifiers deliver air quality equivalent to that found in clean rooms and operating theaters, helping to make indoor spaces safe and virus-free. Existing HVAC systems can also be fitted with HEPA filters or supplemented with mobile OurAir units.
