Product review (4 stars): OEM Filters work best
I know it is a little more than the knock-offs, but we have no problems using OEM filters.
We have a great supplier for our local tap water, but the kitchen plumbing gives it a nasty taste (tastes much better from bathroom or outside spigot).
Whatever it is the sink plumbing does--this filter knocks it out or bypasses it.

We love the fridge, and changes these as the fridge reminds us to.

Great prices on these filters from Amazon (33% less than local Lowe's), and speedy delivery.
