Review on Membrane Solutions Replacement Polypropylene Compatible by Gilbert Pfaff

I wish I had read the other review that mentioned the odd packaging. I am attaching photos of the package I received yesterday - you can see there is no mark or insert on the package that matches the photos of the item in this listing. I have a message to seller asking if my product is legal and actually NSF certified, ISO9001 certified and BPA free. It's so frustrating because that's the water we drink at home. I want to be able to feel good about it. I'll update my review if I get a good answer to this. Otherwise I think he has to return.
