I have only purchased one Dörr product and it was completely unintentional. I ordered a Lenspen Sensorklear sensor cleaning pen. When I opened the box and saw a Dörr Sensor Klear package I was disappointed until I actually looked at the pen through the clear plastic. It is a Lenspen product packaged in the Dörr packaging. The pen itself has Lenspen printed on it and not Dörr. So, I imagine that other Dörr products are repackaged items from other manufacturers. I would inspect the Dörr filter to see if it has any manufacturer's info on it before making a decision on it.
