Featuring 1 micron ultra-fine filtration and 3x dirt retention capacity, it ensures superior removal of dirt, sand, and particulates without altering water taste or odor. Made from 100% pure polypropylene and NSF certified, it fits all standard 20" Big Blue housings, providing reliable, long-lasting water purity for residential and commercial use.

## Description

DGD series cartridges are made of 100% pure polypropylene and are sized for use with Pentair Pentek Big Blue Filter Housing. DGD series cartridges are designed with purity in mind and will not give flavor, odor or color to filtered liquids. In addition, the polypropylene construction provides excellent chemical resistance. The DGD series advanced design combines selective final filtration with proper pre-filter, allowing up to 3 times the dirt retention capacity of similar size sediment cartridges, providing a larger capacity than standard spun cartridges and rope cartridges. The larger the diameter of the filter reduces the load on the particles, and it works faster. Effective filter depth increased by 233%. This increased depth provides extremely high particulate reduction efficiency and additional loading capacity. The design and performance characteristics of DGD series cartridges make them ideal for all residential, rural and municipal and commercial applications.

## Questions & Answers

**Q: what is the recommended manufacture filter change. or the life span of the filter how many gallons?
Thanks**
A: We have a lot of sediment and silt in our well water.  I have been using these close to 10 years now, and I change them every 3 months.  If I go too long, the silt gets past the filter and into the washing machine (that's where I notice it first).

**Q: Will these filters fit the express water whole house filter hsg?they are also 4.5 x20 filters. Would like to use this gradiant sediment filter**
A: Yes, the sediment filter will fit the 20 inch canister. That is a std size. It should go into the first position in a 3 canister setup.

**Q: Can i replace a dgd-5005- 20 with this dgd-2501-20? what are the consequent's replace more often?**
A: The DGD-2501-20 is designed to remove smaller particulate and is constructed of denser filter media than th DGD-5005-20, thus it my need to be replaced more often if the feed water quality has a higher volume of larger sized particulate.

**Q: Where is this made?**
A: The DGD-5005-20 Pentek is made in China.
