iSpring FP25BX4 High Capacity 20” x 4.5” Water Replacement Cartridge Fine Sediment Filter, 4 pieces / 5 microns, White, 4 Count

Bought these in error, I use 3 different filters in my water system; this is the first one in the line. I had to order 4 each of the others to create a set. Now I order multiple sets of three to have some on hand. They are hard to install because you can't see (in my application) the housing going into the filter head, hard to change because they are full of water and therefor heavy.

I wanted to create a custom solution for my water condition after performing a water test. Nick from iSpring responded to all my questions and helped me create the custom solution I needed. Ordered and received all my filter cartridges very fast. Thanks Nick for your help, that is world class customer service.

my original delivery took a little longer thank i think it should have and when it arrived there was some damage to the package. i contacted iSpring support and Sean took care of getting a replacement shipped out immediately. very good service.

Filters the water great.

I,m in montana and my water line is frozen. always pleased with my amazon purchases

still waiting to see more effects on the water

Works great. Michelle and Nick have both been extremely helpful. Highly recommend this company.

Fit perfectly. Easy to install.

I ordered these filters to use in my Big Blue Whole House filter unit and find that they work well. These filters remove sediment from my well water. I have been replacing the filters every 6 months, but I feel like every 4 months would be more appropriate, as they appeared to be full of sediment when I removed them from the housing.I find these filters expensive, regardless of the manufacturer. I have used many of these filters from many manufacturers, and find these to be of good quality. I would recommend buying these filters in packs of 4, to save month, and also 4 should last over a year.I have not noticed any sediment in my applications while using these filters, so they are doing their job. Recommended purchase.

Been using these for few years now. No complaints at all.

Fits my Big Blue system perfectly.
