I got my reply back from them. I sent them my filter, and it had tears in it. Their letter was a carefully worded piece of work, probably drafted by their attorneys, that had a lot of smoke and mirrors in it. They didn't take any responsibility for the filter I sent them, indirectly blamed a lot of outside factors, but nothing indicating the filter was defective. They told me not to buy filters by numbers, as some on "social media" do (no mention directly of BITOG). Just about what you would expect from corporate America. Nothing helpful to the consumer. My last purchase of purolator, I'll use FRAM, I've used them all my life w/o incident anyway. I bought the pure 1 b/c I understood it was a superior filtering product.
