Pentair Pentek P-250A WaterFilter Set,10-Inch ReplacementCartridge Set for Use in the US-1000 Under Sink Drinking Water System,10"x 2.5", 0.5 Micron,Compatible with many Culligan and GE systems, White

We have used the Pentek brand for our Culligan SY-2650 water filter for many years. Fits well, and works well. Much cheaper than the Culligan OEM product.

Good filter and a lot cheaper than the Culligan equivalent.

workes well my 2nd filters lasted a year. a bit to costly though

So far so good. Seems to be an adequate replacement for the Culligan Ste at considerably better price.

I've used these for several years and I'm always very pleased with the clean taste. I change mine every 8 months even though they still perform well.

It's working fine as what I expected.

I turned my neighbors on to this inexpensive and convenient water purification system and now they are enthusiastic users. A few months ago they didn't have a filter for a few days and as they waited for a new one to arrive from Amazon they did a blind taste test of filtered and unfiltered water. All 4 members of the family chose the filtered water as being the best tasting and that is in Portland OR where the water is already known for its purity and taste.

After looking up and down for a w-100RC replacement filter with no luck I came across this set of filters. It fits my American plumber system perfectly and after flushing for about 5 minutes the water is crystal clear and taste good. Hope this review will help anyone else looking for a suitable replacement for their w-100rc cartridges. I will definitely be stocking up on these.
