5 Best Water Softener Resin for Well Water Review

A water softener resin for well water helps to make the hard well water soft by removing the magnesium and calcium ions and replacing them with sodium ions. The process involves backwash, recharge, and rinsing.

The resin is a plastic-like compound that has a major role as it plays in all three steps of water softening. It’s capable of swapping one ion with another.

Just a quick preview of how a salt-based water softener works; The salt you add to your softener is sodium chloride. When poured into the water it dissolves into two compounds:

A positively charged sodium atom and a negatively charged chloride atom. The ersin bed will take the calcium ions and give up the sodium ion.

Eventually, the resin becomes depleted of all of its sodium ions so it must be replenished. This happens when your softener system goes into backwash.

In the back wash stage, the water softener flushes out all the calcium ions to drain and then replenishes all of the sodium lost to the ion exchange process.

The backwash is then directed to a drain that carries the ions to the waste water management facility or septic tank.

All conventional cation water softener resin beads are engineered to soften hard water. But before replacing your water softener though, there are few things you should make sure of such as what kind of media you have inside your water softener and how much media is contained in your mineral tank.

In case you are looking into buying a water softener resin, you will want to look into a resin that’s precisely made for your type of water hardness.

If you have an iron water problem in your water , you should get an iron filtration system made precisely for your type of iron.

Dissolved iron to as much as 6 mg/ltr could be eliminated through softening. A Fine mesh resin is most notably the best in removing iron from well water.

For tannin (produced by rotting vegetation), you can find anion resin that may well clean out tannin from consuming water.

In cases where you have a high concentration of chlorine, then it is a lot harder for any water softener resin. If you want the chlorine away, get a backwash carbon filter with a few cu. ft. of carbon.

To concur crappy well water, we have compiled a list of the best water softener resins. Most of these ion exchange resins are generally made with a typical particle dimension of around 0.5 millimeters. So let’s have a deeper look at each of them.

Best Water Softener Resin for Well Water

1. AFW filters High Capacity Resin for Water Softener (8% Crosslink 1/2 cubic foot)

High capacity is a conventional gel polystyrene sulfonate cation exchange resin that’s made for big tank sizes. The particles are a high-quality cation exchange resin whose structure is held together by 8% crosslink ½ cubic foot styrene cross-linkage replacement resin.

While the hard water passes through the resin, the calcium and magnesium ions are removed and replaced with the sodium ions in the system.

This process repeats itself but won’t keep going eternally. With an average resin life span of 10-20 yrs, the resin bed will be exhausted and you will need to be replaced before the hardness ions begin to a breakthrough in the effluent.

Throughout this routine, the resin should be back washed with a salt solution. The water softener resin needs to be regenerated or rinsed to allow it to keep its capabilities.

Anytime you are deciding on a cleaning substance for that use, make it a point it’s made clear to get rid of the mineral buildup. Usually, you can find a resin cleaner that is targeted on a definite element – for example, manganese and/or iron.

You are also assured of a quality product with this resin because it has been tested and certified by NSF and FDA.


  • Value for money.
  • Ready for use anywhere.
  • Affordable.
  • NSF and FDA approved.

2. Purolite C-100-e Cation Exchange Resin For Water Softener( 1Cubic Foot)

Purolite is another common cation resin that can also clean out iron that is often wide-spread in a huge number of private wells across the country.

It’s a 1Cubic Foot, US-made resin that can be used with many models. It’s another approved FDA product that has proven to be a top-value water softener resin.

Through a standard softening process, the resin captures the magnesium and calcium and replaces them with sodium and hydrogen ions.

The resin’s role is to saturate the water of the ions that causes the hardness problem.The second stage is recharge which involves the transfer of brine solution in its tank, and into the mineral tank.

In this phase, resin works by trapping sodium ions from the brine solution. During the third stage, the trapped ions in the second phase become useful.

This water softener resin may also get foiled and this leads to loss of performance of the system, requiring significant more regeneration employing the same amount of salt, which will cause raised salt usage.

To take the magnesium and calcium minerals out of the resin beads, a resin cleaner is generally applied in the equipment to exchange the minerals for salt ions.


  • Made in the USA.
  • FDA approved.
  • Safe for drinking and cooking.
  • Compatible with many water softeners.
  • Value for money.


  • Strong smell.

If you answer yes to any of the following you can be fairly certain that the water flowing into your home is hard water:

  • You buy expensive soaps and detergents that other people rave about but your clothes still never quite look clean after being washed and you still feel sticky when you get out of the shower.
  • You still have filmy glassware however many times you rinse.even with a good dish-washing liquid unpleasant smell, often a very sulfur-like one.
  • Your water is unpleasant tasting.
  • Your household appliances do not seem to last as long as other peoples.

In that regard, we recommend you buy yourself a salt-based water softener. This is the most effective solution available for eliminating the effects of hard water in the home.

Removing calcium and magnesium from the water will prolong the life of appliances, improve the efficiency of detergents and cleaning products, and protect the pipes from scale buildup.

These effects save homeowners money by reducing the amount of detergent that needs to be bought and by prolonging the life of the appliances.

In general, the water softener can pay for itself in five to seven years despite the initial high installation cost. Although there are cheaper salt-free alternatives available, they rarely provide the kind of satisfactory results or cost savings that a salt-based system offers.
