Mann Filter is a German company but they manufacture filters that are used on many pieces of equipment in the US.  From German equipment makers like Deutz, Hatz, Atlas Copco, and Mercedes to American ones such as John Deere and Caterpillar, if you see the distinctive orange colored air filter it is probably a Mann.  Some of these filters are difficult to find or expensive from the original equipment manufacturer.  Big 4 Filtration is a Mann distributor and we can cross your OEM filter numbers to get you the filter you need.
