As in, sure Jodie Arias looked great with her clothes off but who wants to be dissected in the shower because you didn't look deeper than the skin.
IMO, the nitrile ADBV makes it a 7.5K filter. We don't have efficiency specs but presumably they are average... ~92% @ 20 um and absolute around 40 um.That's enough for the average engine . Some of the cheap filters may be worse because the money is in the media and these are price point filters. Because they are cellulose media, you have to consider the amount of media area in the filter as well so you don't overload the media with too long an OCi.
As usual JA, my IQ points seem to improve about filters after you "school" me on them.
I know you have stated the numbers about MC filters but in your opinion is it rated as an "average" filter?
