Pentek DGD-5005 Big Blue Water Filter, Polypropylene, White

Usually used for years they are great. I just need to change it once a year. Repeat customer I am.

Previous owner did not maintain anything in this home, so it was no surprise when we went to replace this filter. The old one was the yarn style and it looked like brick red yarn. We have been using this new filter for several weeks now and it seems to be doing the job. No discoloration in the water, less staining in toilets, and the pressure has not decreased.

Good price, quick delivery and it fits my filter.

Our city has water that testing shows greatly exceeds federal water purity standards. Still, my wife doesn't trust it. So a few years ago we had a whole-house charcoal-based water purifying system put in. These filters are used as a pre-filter for the system, and it's amazing at how deep brown they are after 6 months. Shocking, actually. I expect that they'll extend the million gallon/10 year life of the charcoal system by a year or two. They're very easy to change--no plumber needed. You can read the instructions and then watch a video, The keys are to push the pressure relief valve for 15-20 seconds and use the correct wrench made for this size filter housing. Use food-grade silicon grease when changing the o-ring washer. If you want a sediment filter, I highly recommend this one.

Works good for sediment and iron but priced much higher than alternatives that I’ve tested and are just as practical. Double the price of some filters that work just as good.
