The PENTEK-DGD-2501 heavy duty filter cartridge is manufactured from 100% pure polypropylene and is sized for use in Big Blue and other heavy-duty filter housings.

  • Effective filter depth is increased to a full 233% of standard spun-polypropylene or string-wound filters

great product at a great price Review by KayKay
Had been purchasing these filters from our local water system dealer for a few years. The business left our town and I could only buy via phone from a branch office several miles away. Plus shipping was twice the cost of the filter. I was able to buy 4 filters with free shipping for a great price. (Posted on 11/4/12)

Cost less than local dealer and the filters shouldn't go bad sitting on a shelf until used. (Posted on 7/1/12)

Not very tight with the specs microns Review by Hamlet
This filter does not meet the 85% nominal rating for particulate reduction. Mfg Claims 90% by phone 85% on PDF specs but a 35% nominal rating is more accurate. It passes most all 1um particles 60% of 5um 30% of 10um etc. Thought I could use this prior to my expensive final but nah it doesn't cut eno (Posted on 7/8/11)
