Pentek Pentair DGD-5005 Big Blue Water Filter, 10-Inch Whole House Sediment Filter Cartridge Replacement, Dual-Gradient Density Spun Polypropylene, 10" x 4.5", 5 Micron, Pack of 1

Works just like any other water filter and is cheaper than in a retail store.

Excelente filtro para el agua de mi sistema hidroneumático

This is the exact product I wanted for my home water filtration system. It is more than 50% less than the stores that sell these products near me - a huge difference. I love that the filters are available in bulk so that I can stock up and never run out. Great filter for your money.

The dual gradient filter by Pentek is by far the best I have ever used, and I've tried them all. I pump spring fed creek water to fill my cistern through these filters and it has a fair amount of silt in the water. This filter lasts the longest on a fill before clogging and the water is the cleanest compared to the other pleated filters and ball of string type I've used before. I also use a 20" version as a sediment filter coming out of the cistern to the softener. The life of this filter greatly depends on the cistern filling filters I use. I like the dual gradient style because they are more resistant to clogging than any other. Kind of reminds me of the outer and inner air filter idea on a big diesel. I'll use these as long as they make them.

I rarely leave reviews, but this one indicates a great product. I’ve tried various filters, from cheap to expensive, and this one surpasses expectations. My well water is high in iron (reddish clay), but this filter works wonders. Highly recommended, though the price is on the expensive side.
