A blue column labelled "Filter Group, a Mann+Hummel company" lists the "HVAC-filter range" with bag, compact and panel filters. Packaged Filterpak filters hang on a lake-themed wall under the slogan "Keep it clean", and a screen states "Filterpak is a Finnish pioneer in the air purification industry."
