Pentair Pentek CW-F Sediment Water Filter, 10-Inch, Under Sink Polypropylene String-Wound Replacement Cartridge, 10" x 2.5", 10 Micron

Does not deteriorate like the paper filters, stands up to the pressure from the deep well pump. (This filter is installed before the water tank.) Though one of these does cost more than two of the paper filters, I feel it is worth it in the long run. I do not have to replace the filter elements as often.

I have well water in a high acidity, high clay area, so my total dissolved solids is pretty much off the chart. I installed a series of three filters, using this as the first stage, followed by a 5 micron membrane filter and a charcoal filter. My water has never been cleaner or tasted better.

We have a well and we use these to filter the water we use in the house. It is nice we order enough for the entire year and can replace them monthly with out having to run to the store and buy them.

Works good, gets rid of alot of sediment.

These work fine in my simple whole house system. Would recommend for anyone who doesn't want to spend a fortune on these.

Yes it is doing a good job

It works fine and the price is right!

Great product filters are high quality!
