You're right; I'm sorry that the attitude, if not the language, was inflammatory. It's just that I've spent years trying to educate folks against products like this, a solution looking for a problem, that I yank out what little hair I have left when I see someone use their bike as a lab rat and promote stuff like this as being effective or beneficial by saying "no problems yet." In what engineering curriculum do they teach that proof?
Transparent rationalizations aside, you've admittedly not checked the performance of "paper" filters (they're not strictly paper), and you've made assumptions based on unproven claims. So you're correct; it's your turn. Do some research; become your own expert...or not. I'm not going to attempt to educate you, because you'd only argue till you're blue. Five years as a motomag tech editor taught me that lesson.
