Direct replacement for factory filter
Worked as advertised without issues. Came fast and were less expensive than the Samsung variant.

Nice clean water with no oder.
No problems with product, very easy to insert. I usually run the faucet for a couple of seconds to clean out any stagnate water before drinking or use in cooking. Good water flow.

Good filter not available locally
It has been difficult to find these filters locally for a few years. When our kitchen was remodeled 12 years ago the Westinghouse undersink systems were sold at Lowes. I've tried other filters before but I can't recommend the most advertised company since they couldn't deliver after 2 purchases. Took a long time to get their email ads stopped. Glad we didn't call a plumber to remove or replace a working system. Old filter had gone 12 months + and flow had slightly reduced on our hard water. These new filters work well and price is reasonable.

Perfect fit. Clean water.
I replaced the old under the sink water filter yesterday. Perfect fit. Let the cold side run a few minutes. Now we're drinking clean water. Great value.

The filters seem to be good.
The filters seem to be good. Of course, this is subjective on my part. I have no means of proving or dispruving their effectiveness.
