Do I Install A Water Softener Before Or After My Water Filters?

I’m installing a water softener on the side of my house, out there I already have 4 small filters and one large carbon filter. Do I install the softener before or after these filters?

    The purpose of the water filter is to remove sediment and pieces of debris from the incoming water. The filter should be placed before the water softener and use a five micron media. You can gang filters of a larger size first if a lot of sediment is present. If you allow the sediment to enter the softener it will coat the beads and reduce the efficiency of the softener. This will also require more cleanings of the softener bed. Small pieces of debris can also damage the valves and water flow measuring devices in the softener. I am amazed at the stupidity of some of the contributors.

    Thanks for your response John. Even though you might have been a little harsh on the other guys. I am glad you addressed it right away and yes you are tight. The filters should go before the softener.

    Well in my point of view,both answers are right, wether it is before or after because both of them, softener and filters, are for different functions, but what is the best condition where we are going to put the filters, even a cartridge or a carbon filter or both cartridge and carbon, for me, I might better use the filter “before” the softener in which it will be a better control of the blockage/sediment/odor going to your softener. Hope this could help for a better discussion, 🙂
