Pentair Pentek DGD-5005-20 Big Blue Water Filter, 20-Inch Whole House Sediment Filter Cartridge Replacement, Dual-Gradient Density Spun Polypropylene, 20" x 4.5", 5 Micron, (Pack of 2), White

Been using the Pentek DGD-5005-20 in my Big Blue housing for a few years now and it's doing exactly what I need. The dual-gradient density design does a great job catching sediment progressively — coarser stuff up front, finer particles as water moves through — so it doesn't clog as fast as the cheaper single-layer filters I tried before. Water pressure has stayed strong. Fit was perfect in my standard 20-inch Big Blue housing, no issues there. Installation was straightforward, and it seems well-built for the price. I'm planning to just keep a few spares on hand for swaps every few months depending on usage. Great value if you're dealing with sediment, rust flecks, or dirt in your water supply. Would recommend to anyone with a whole-house filtration setup

These work well for me. Seems to remove a lot of the soluble iron. These are made in China and for a simple dual gradient wound cartridge I am ok with it. For my carbon block I buy the Pentek series made in Dover, NH, USA and the price of those is reflected accordingly.

Great product. Received quickly

Had this filter in my system for five months. It performed perfectly and filtered out a lot of containments

Maybe coincidence but I’m writing because it may help someone, I sure didn’t know how to deal with it. We have a rain catchment system here in New Mexico that feeds the house supplementing public water. We also had what we used to call a 100 year storm (probably becoming normal now) that flooded everything. We presume it overran the tank with groundwater First I filled the dog’s bowl and it was brownish and the toilet also was filling with sediment so I changed the overdue filters. What happened next was the strangest thing I’ve seen and no one I’ve found can explain it. Perhaps a chemist reading here might explain. The water came out of the tap looking exactly like dishwater, soapy as if full of detergent. It poured into a pitcher with a head on it that you could scoop out by hand (photo). Eventually it came out looking more like milk. I let some sit for a couple of days (glass in background) thinking it must be air bubbles, but after two days it had indeed settled a bit but remained a foggy gray. No odor or anything but it looked weird. We had a 25 micron paper filter ahed of the carbon 10 micron filter and started wondering if the paper filter was adequate. I shut off the rain water until this new filter arrived. It may be coincidence or time, all I know is that since I swapped in this filter and turned the rain water back on the water has been clear. I was concerned about flow dropping from a 25 to a 5 micron filter but there’s been no perceptible change. FYI

Just know they look a little different than the original/oem. Initially they look a little taller, but they don't have the plastic end cap and black rubber seal. So overall length is actually the same. Fits perfectly. Working well so far.

Work as intended, have bought before and will continue to. Never had issues with them on a water well filtration set up.

I forgot to replace my filter for a year and well I needed a replacement. This looked exactly like the filter I used for last time so I bought it. Installed it and it working as expected. No problems as Its the correct size. Will buy again in 6 months. This time not forgetting to replace it for a year. Changing a water filter sucks when you have no water to clean the housing. Lesson Learned and will have a bucket of water for cleaning. Also not replacing during a freezing winter can help also.

Muito bom

Pacco arrivato puntuale, tutto ok

Use these on my well. They work well.

Work excellent and are as described. They're more expensive than they should be.
