Thank you.
Blackstone testing isn’t necessary in this case since there is an abundance of information and testing done on the matter on the net already. I just wish the members didn’t overlook the original question of “why?”, much less mentioned their % filtration knowledge.
The reason I bring this up is because I was appauled recently when a friend of mine went to the Toyota dealer to get his filter. I didn’t have a problem with him buying the filter but what I did mind is when he told me that his reason was that it’s the best, without any facts/data or information to back up his claim. That didn’t sit right with me so I wanted to shine some light on the subject.
Something to consider when somebody mentioned that PureOne is restrictive.
