They're not better because they publish it, they're better because they build em that way.I suspect WIX filters may be better simply because they give technical data on their website. Data such as what size particles they filter out, flow rate, burst pressure of can, back flow valve, flow rate, by-pass valve, and other. I have not found other brands that do this. Fram certainly does not.
I trust a company more that will print technical data about their products like this.
