Pentair Pentek ECP5-BB Big Blue Sediment Water Filter, 10-Inch, Whole House Heavy Duty Pleated Cellulose Polyester Replacement Cartridge, 10" x 4.5", White End-Cap, 5 Micron, Pack of 2

They are the best in my opinion. And they are well worth the money.

What's the benefit of pleated vs the wound string? The pleated offers MUCH more surface area and lasts much longer. I gave up on the wound string filters years ago because of the superior water flow and longevity of the pleated filters. I really like them. But now, the experts are recommending spun polypropylene filters. These new polypropylene filters don't have a rating the same way that pleated filters do because they have a range of filtrations --- the outer layer may be rated for 20 micron, while the inner may be rated for 5 micron. This means that the bigger particles are trapped on the surface and smaller and smaller particles are trapped as the water moves toward the interior of the filter. The experts say that this method is superior to the pleated cellulose filter design, but I'm not sure. I'm testing both kinds in my house now, and they seem to be performing equally well for longevity. I don't think you can go wrong with these pleated filters. Of particular note is that the pressure drop in these filters is so low that it's very well suited to low water pressure situations. We have a gravity feed spring supplying water at 20 pounds of pressure in the basement. After the filter, there is 19 pounds of pressure, still enough to take a shower.

Such a great price! So glad I came to Amazon to buy these. We previously bought in bulk from another filter site and were paying nearly double! These work great!

I have tried many different filters at many different prices for our home water softener system. This filter provides the absolute best "bang for the buck". A 5 micron filter is really ideal for optimum filtration (lower than 5 micron filters don't seem to last as long and higher micron filters don't seem to perform as well) this filter takes out the "bad stuff" (sediment/iron/whatever) and lasts around the 3 month lifespan a decent filter should. A great value here.

Works great in my GE whole house sediment filter. Coming from 5 micron to 1 micron I see no drop in water pressure. I am using it on municipal water and mainly filter iron sludge that comes from older cast iron pipes. Changing filters every 4 month or so, by the end of the period filter is all yellow and a bit slimy, so you can see what you avoid in shower and such. Filter will not do anything to chlorine or any other impurities but a great one on the entrance to the house for all the sediments. I keep on buying them from Amazon where they are reasonably priced and delivered to you door. Can I find them locally, probably, but that gas spent driving and time not really worst a dollar or two of savings. By the way, picture is from an older one, new ones got a bit redesigned with thicker ends and black rubber washer in the center, still fits great and work fine.

Very effective

Wilford Brimley said - check your sugar and check it often… I say check your filters and change them often. It’s cleaning the water that your family depends on. These filters have very good fit and quality but no filter is designed to last forever… use good filter like these and change them!

I've used Pentek exclusively for the last several years. Prior to that I've used others and believe me none of them work nearly as good. We are on our own well and many impurities can be dredged up, so we depend on a great water filter and Pentek is the best by far. Fresh, clean and odorless water every time!
