Pentek Pentair DGD-5005-20 Big Blue Water Filter, 20-Inch Whole House Sediment Filter Cartridge Replacement, Dual-Gradient Density Spun Polypropylene, 20" x 4.5", 5 Micron, Pack of 6, White

Work excellent and are as described. They're more expensive than they should be.

The filter worked very well. The city did some water pipe repairs locally and mud came down the line. The filter was replaced by a plumber after only 3 days. A simple white filter was covered with dirt. The water quality in the house remained excellent. It saved a lot of money replacing fixtures etc.

Went from a smaller micron to a bigger one in the same brand, plugged up right away, doesn’t make sense at all should have lasted longer

These work as described and the six pack are pretty good value compared to other on line suppliers.

These dual media filters are incredible. I have a 3 stage system that is fed from lake water. This filter is my first stage, then I go down to 5 micron, then carbon, then UV. Compared to a standard 20 micron filter, I would say this one lasts about 3x as long before becoming plugged. If your water is rich in sediment or tannin, and your filters are plugging up fairly quickly, this may be a good option. You will still need something finer before UV, but its a great initial step.
