MANN-FILTER is a German filter brand. The range covers oil filters, air filters, fuel filters and cabin filters for cars, vans, trucks, and agricultural and construction machines. On forums MANN-FILTER is named together with Mahle and Hengst as one of the three big European filter makers.
In its own product brochure MANN-FILTER stresses tested original equipment quality. The company also says its production sites are audited regularly. These are statements by the manufacturer and not independent tests.
On the American forum Bob Is The Oil Guy opinions on MANN filters differ, but the build quality is often praised. One member writes that he knows of no more solidly built filter. Another reports that a MANN filter collapsed like a straw in his engine. He does not know whether the filter or his crankcase ventilation (PCV) was to blame. In another discussion the published efficiency of 99.9 percent at 9 micron is questioned. The writer argues that a common test standard is needed to compare filters fairly.
On the German parts site autodoc.de MANN-FILTER oil filters score about 9.5 out of 10 across roughly 3,400 reviews. Users mostly praise the quality. There are also complaints about fit and, now and then, a cracked filter.
Forums warn about counterfeits. A T6 forum has a thread about a possibly fake MANN oil filter. Users advise checking the part number and the country of origin rather than relying on the box alone. Genuine MANN filters for first fitment are said to be often made in Germany.
In online shops filters are listed under a code, such as HU 7010 z for an oil filter element. Such a number is specific to certain engines. Look the number up via the registration, the engine type or the number on the old filter. For tractors and machines the year of build and the engine matter as well.
The brand has a good reputation on forums and in shop reviews, with a few isolated complaints about fit and failures.
They are three large European filter brands. A direct comparison test of the three is not to be found on forums. Choose the filter that is specified for the vehicle or machine.
Check the part number, the packaging and the country of origin, and buy from a reliable supplier.
