There was a problem filtering reviews right now. Please try again later.
The new granules are too small and they collapse together on bottom which leads low water flow.
I returned the remaining two after I realize the clogging issue. I replaced the item with the original filter with the case
I will NOT ever try to save a few bucks with this product again
