Specifications Sheet: Pentek DGD Series Specs

DGD-2501-20 cartridges are manufactured from 100% pure polypropylene and are sized for use in our Big Blue® filter housings.

DGD-2501-20 cartridges are designed for purity and will not impart taste, odor or color to the liquid being filtered. Additionally, the polypropylene construction provides superior chemical resistance and is not prone to bacterial attack.

The DGD-2501-20 advanced design combines selective "final filtration" with appropriate "pre-filtration" to achieve up to three times the dirtholding capacity of similar size sediment cartridges and many more times that of standard spun or string-wound cartridges. This performance enhancement is achieved by combining two separate gradient layers in one filter.

The larger diameter of the pre-filter reduces the particle load to the post filter, allowing it to operate at higher velocities. The effective filter depth is increased to a full 233% of standard spun-polypropylene or string-wound filters. This increased depth provides for very high particulate reduction efficiencies and added loading capacity.

The unique design and performance characteristics of the DGD-2501-20 cartridge makes it an excellent choice for all residential, rural, municipal and commercial applications.

  • Manufactured from 100% pure polypropylene
  • Designed for purity and chemical compatibility
  • Two separate gradient density layers enhance cartridge performance
  • Three times the dirt-holding capacity of similar sized sediment cartridges

Reviews from the same Filter Series

Definitely works5 Stars
I use this as a pre-filter in my whole house system. Our city has a great new water treatment facility, but there must still be sediment in the distribution system as this filter sure manages to remove a lot of it. It lasts about 9 months for me and you can actually see the different filtration sizes when you change filters due to the different coloured rings on the end of the filter. - Mark C.
Lasts forever5 Stars
The DGD 5005 filter lasts a lot longer than the generic filter I was using previously! I will definitely continue to buy these. - Cara

Removes fine particulate matter5 Stars
Any filter can remove "normal" particulate matter but have a great amount of difficulty removing ultra fine clay particles. This filter is fantastic about completely removing the clay particles. Also, changing the filter is exceptionally easy. - Jimmy Bollman
