Membrane Solutions 10 Micron 2.5" OD x 20" Length String Wound Sediment Polypropylene Replacement Water Filter Cartridge - 6 Pack

Works great

This is my first purchase here. I have a Rainsoft water softener and osmosis system. The first filter for water coming in from my well is the 20 inch cartridge. I usually change it monthly, depending on the mood of the well and how much rust/gunk it sends in. Well, I am one of a handful of customers that use this “yarn filter”, as I call it, so my Rainsoft distributor asked if I still want it or would switch to the other kind, as they have to put in a pretty big order to get it and then they have these sitting in their warehouse. I replied that I do not care for the “smooth ones”, as I call them, so I decided to check on Amazon if they were available here. They are and my Rainsoft rep said they should fit. They fit well and do the job, so I am very happy! I can change them as I choose, and no longer try to soak them to reuse them in fear of running out.ONE thing I will say: When new filter is put in, directions are to hand tighten cartridge- WEll, I had to use the wrench just a bit to tighten, as it leaked at first. But now I know, and you do too! For rust in well water, I wouldn’t trade these for anything. I have been using these since 1986!

They filter the water extremely well.I was very surprised what was in our drinking and cooking water. Glad were not consuming that contamination.This is my 2nd order of this 6 pack. It's a really good price and made well.They have food grade plastic collars in the cores, at each end, so the ends don't fray or become unraveled.I use this in my Gordon's water system filter cylinder and it fits perfectly.

Works as advertised

Ordered the wrong size. My fault.

So far these are great filters

Good filter quality Fits well

The filters produce excellent water quality. The filters lasted through twowashing too
