    • Works well as a water well filter. Cheaper than the store version
This filter works really well for the price. This is used to filter put sediment from the well water before it goes into the water softener. It works really well and I haven't had any issues with it. It was easy to install and doesn't significantly reduce the water pressure. It fits just like the oem version but because its on Amazon its way cheaper than the alternative that we could buy in store locally. ... show more

    • Easy water filters
These work for me and have for several years. These are what I use for the well water before it goes through my water softener. Easy to reorder and easy installation. I change these about every 3-4 months.
