MANN FILTERS are high-quality products. They are manufactured in large numbers, tested several times and meet high requirements. This is why we invest a great deal in research and development, production and quality assurance, after-sales service and in the knowledge of our staff.
Thanks to this corporate philosophy and our product philosophy, MANN+HUMMEL has become a leading filter manufacturer whose products enjoy an excellent reputation and set international standards as high-quality products.
Others would very much like to utilize this good reputation for their purposes and turn it immediately into money. To end this end, they build identical filters to our and even place them in packaging which looks similar to ours. Even the address, company logo and company lettering are the same, although it is supplied by somebody else.
Obviously these brand-name pirates who are geared to short-term success can only produce items which cannot be compared with our products. At first sight, you do not notice any deception. The tempting offer is convincing and the copied filters even perform reliably as intended. But then, sooner or later, their proneness to damage comes to light, thus proving that there is a world of difference between the originals and copies. Not only in the country of origin but also in fulfilling warranty claims.

Obviously, whenever possible, we counter this type of competition by legal means. But the work involved in investigation and providing evidence is enormous and the chances of successfully undermining such criminal activities is very small. We therefore place great hopes on our customers. With their knowledge of the market and their quality expectations, they can place obstacles which brand-name pirates cannot overcome.
