Donaldson has 38 plants around the world. The ones I got today came from 10 different countries. I've only visited the Mexican plant, and it is nice. I've cut up lost of them, including some real nice ones from Indonesia.
Where they are made for your country depends on where your car was made, how popular that filter model is, and a lot of other factors. Since we have a lot of vehicles here that are not sold in the US (made in Japan and other parts of Asia), many of those filters come from there. We have a lot of European cars and trucks, so I end up with a lot of UK, Germany, Italy and Sweden.
Some filters are probably made in a dozen countries or more. Sometimes I even get mixed supplies.
When choosing between the two, I think Donaldson is the best. That is why I sell them. But at least you are out of the swamp that contains so many other brands.
