Ronaqua 10 Micron Sediment Water Filter Cartridge 10"x2.5", NSF Certified, 4-Layer Filtration for any 10-inch RO Units & Whole House Systems, Compatible with Culligan P5, AP110, WHKF-GD05, 6 Pack

I order these for our in-line water filter and they work very well. We have horrible sulfur water that stains my sinks, tubs and clothing over time even with every day cleaning. These filters help cut down on that a lot and also makes the water clearer and not smell like rotten eggs.. which is definitely a plus.

These are quality units that work as advertised and certainly do allow an R/O system thrive. I would honestly recommend doing 3 in a row though depending on your setup. 2 in a stack for me running 24/7 only lasts 3 months with 550 ppm Michigan well water. If your water is city water or municipal water then probably you won't have to change filters for months but if you're someone like me fighting well water then you will need to consider a pre-filter before the 2 or just buy their bulk and change out your filters every couple months.

Exactly what I was hoping for.

I bought this for my Mistor pump. They work well

I use these in our whole house well water line. Great for filtering out impurities in the water line leaving no after taste or reduced water pressure. If you notice reduced water pressure, change the filter as it may have caught more impure sediment was water table changes. Great for filtering city water too. I will continue to purchase as long as I get a good price. The water you drink is important to your health!
