Product review (5 stars): Better than I anticipated
I read reviews about how the B version was better as far as getting majority of the crap out of your water and thought this version wouldn't make much of a difference, but my current filter was expired and I was shopping on a budget. I poured a glass from my expired filter then one from this A version. I taste a great difference and didn't spend as much as I would've if I got the B version. I'm happy with my purchase.
