Maybe, but the sad thing is that there even is such an issue to worry about. People don't tend to cut filters in anticipation of a warranty claim. They do so to see how things worked out, or how things look. They're not testing them rigorously in a lab - they're getting more of a subjective viewpoint. Just like people have complained for decades about "cardboard" end caps or skimpy media on the orange cans, or wavy media in various products, people will complain about tears in filters.
"Cardboard" endcaps had become essentially a meme over the years when taking apart filters. Now, it's Purolator's turn with respect to tears. Fram intentionally used "cardboard" and skimped on the media in the orange can. What's Purolator's excuse? Hear no failure, see no failure, speak no failure? Torn media is a media failure, plain and simple. Until it comes to pass that torn media becomes the norm in the filter industry, I don't have to accept it, and if a filter brand becomes known for tearing, I won't accept it.
You would think that, given the amount of time Purolator has been making filters, they would have mastered sturdy media, not to mention figured out how to glue pleats in an even fashion. Obviously, that's not the case.
