Product review (5 stars): Water Filter
I had been buying my replacement water filters from a brick and mortar store, but went looking for a better price.  I came across this 3 pack, and it was only about $20 more for 3 than what I was paying for 1.  The filter is an replacement for the OEM and works great.  When these 3 filters are gone, I will replenish my stock with the same product.
