Well that was almost 100 years ago, and a lot has changed since then. Just because they did it first, 93 years ago, doesn't mean they're doing it to any degree of competence now.
Yes and to put it directly on point, Purolator US has been half owned by
Mann&Hummel for 10 years now and fully owned by M&H for 3 years. In my observation, Mann and Hummel has shown a lack of leadership in the areas of QA and QC. Any company is only as good as it's leadership. And while the defecation has landed on Purolator US as it runs downhill on this board, the buck ie. responsibility, stops right at the door of Mann & Hummel. And thus when I refer to Puro US QC/QA issues I will always put M&H first before Puro US.
And also on point, while the topic is an example of poor QA/QC with a louver design, what it is NOT, is in 'any way' proof that louvered center tubes 'done properly' are not just as effective as a hole design. The link below shows a recent example of louvers done properly from the same manufacturer in the value tier ProLine filter with a solid results. Important imo to point that out as some might confuse the occasional posted misinformation about a louvered design being inferior, to the fact that there's no proof of such.
