Tier1 1 Micron 20 Inch x 4.5 Inch | 3-Pack Spun Wound Polypropylene Whole House Sediment Water Filter Replacement Cartridge | Compatible with Pentek DGD-2501-20, 155360-43, P1-20BB, Home Water Filter

Does a great job filtering our water.

I have a lot of iron in my well water. I had a 20 micron filter and a 5 micron filter which helped but we needed more. This 1 micron filter reduced the rust content considerably over what we had before. Not a panacea but a good product.

Fit as described!!

Good product. Can be found cheaper elsewhere but it’s super easy to open Amazon app and click buy again. Price has been slowly increasing. No noticeable reduction in flow till it’s time to change it.

This was my first order of these filters. They look identical to the ones I replaced in my new house. They were priced right. My order was filled promptly. I would recommend these water filters.

I buy these for my iron rich well water 2.5ppm. They catch all the red iron but the clear iron will still get through and oxidize later so It doesn't cure it, just reduces the problem. I've yet to have a problem with these filters in the 2 years I've been using them and because of all the iron I can tell they work (red outer, white inner)

We have really hard water and this water filter takes care of the calcium built up.

This filter was a replacement for the filter in my whole house water filter I had installed. Great price and does the job.
