Pentair Pentek ECP20-20BB Big Blue Sediment Water Filter, 20-Inch, Whole House Heavy Duty Pleated Cellulose Polyester Replacement Cartridge, 20" x 4.5", Blue End-Cap, 20

I've been using these filters in our whole-house rainwater system that serves as our primary potable water source for 9 years, so I've probably bought them over fifty times. They hold together well and filter the water exactly as they should. As long they make them I'll continue to use them.

Unlike some comments, the Pentair, Pentek ECP1-20BB 1-Micorn filter does not come packaged with notations not to use with non-chlorinated water. We use it on our well and even with just pressure tank pressure (Less than most city supplied water), it works superbly. Will buy again. PS: We have a professional well company who also recommends this filter.

It is what it is advertised as.

Filter is good quality!

work great

Bueno

Filters fit great in the housing and after checking on them after 30 days of use, they seem to be stopping all of the sediment as intended.

For my well water, great pre-filter

This 1 micron filter is what I need, was delivered rapidly and fits the filter housing perfectly. What is not to like?

Works great

Works and price is cheaper than locally available. Second purchase of this item.

Great price

Works as expected
