Mortons water softener salt is the Morton brand's line of pellets, solar crystals, additive blends, and potassium chloride. Bags run $7 - $40 depending on the product. The softener treats them all the same; the differences are dissolving behavior, residue, and additives.

## The Product Line at a Glance

The core products are pure pellets and solar crystals. Pellets are compressed solar salt at about 99.5 percent purity, and crystals are coarse solar salt dried and graded without compression.

Additive products include a resin-cleaning blend and a rust remover formula. Both cost $3 - $5 more per bag and target iron and mineral fouling.

Potassium chloride appears under a separate label and costs three to four times as much. It works in the same softener with a setting change.

## Reading the Bag

| Bag wording | Product | Best for |
|---|---|---|
| Pure and natural pellets | Plain sodium chloride | Most homes |
| Solar crystals | Coarse sodium chloride | Dry rooms, budget |
| Clean and Protect | Pellets with resin cleaner | 1 - 2 PPM iron |
| Rust Remover | Pellets with iron-targeted additive | Visible staining |
| Potassium chloride | KCl pellets | Sodium-restricted households |

The front of the bag is marketing; the back has the details. Look for the sodium chloride percentage, the bag weight, and the additive description.

A bag that says "99.5% pure" without naming the substance is using a standard claim. A bag that names sodium chloride and the percentage is giving you a number you can compare.

## Pellets vs Crystals

Pellets dissolve evenly and leave little residue, which keeps the brine clear and the tank cleaner. They also flow through narrow fill openings, which matters for cabinet softeners.

Crystals cost $1 - $2 less per bag and dissolve faster, with more fines that settle as sludge. In a humid space they absorb moisture and bridge more readily.

The choice is maintenance versus price. A dry utility room and an annual tank cleaning make crystals a reasonable buy. A damp basement makes pellets worth the premium.

## Additive Products

The resin-cleaning blend helps when iron is present at low levels. It lifts iron from the beads during regeneration and slows the loss of capacity.

Rust remover targets the same problem with a different formulation. Both are maintenance products, not treatments.

Neither replaces an iron filter. Softener resin tolerates about 2 - 3 PPM of dissolved iron before fouling accelerates, and no additive changes that ceiling. Above that level, an iron filter at $800 - $2,500 installed goes ahead of the softener.

## What a Year Costs

A household using 25 bags of pure pellets at $9 spends $225. At $7, it spends $175; at $12, $300. All three sit inside the $120 - $400 annual range.

Additive pellets at $13 per bag raise the same use to $325. Potassium chloride at $30 per bag raises it to $750, which is why it is a targeted choice rather than a default.

Equipment costs more than salt in every case. A softener is $600 - $2,500, installation $500 - $1,500, and the installed total $1,200 - $4,500. Salt is the running cost, not the purchase decision.

## Filling the Tank

1. Confirm the softener is in bypass or between cycles.
2. Fill to two-thirds at most.
3. Pour slowly and break up clumps.
4. Never tamp or pack the salt.
5. Keep the level above the brine line.
6. Check monthly and clean the tank annually.

A full tank reduces air circulation and encourages bridging. Half to two-thirds is the range most manufacturers recommend, and it is the range that keeps the brine draw reliable.

## Buying and Storing

Buy from a store with turnover, and check the bag weight rather than assuming 40 pounds. Six to ten bags is a sensible purchase for most homes, stored on a pallet off concrete.

Sales in spring and fall drop the price by $1 - $2 per bag. A pallet saves $25 - $50 a year if storage is dry, and costs more than it saves if the bags fuse in a damp garage.

## Why the Name Gets Pluralized

"Mortons" is a common search spelling, and the brand is Morton Salt. The product line is the same regardless of how the name is typed, and the bags do not change.

That sounds trivial, but it explains why the same product appears under several titles online. A retailer listing may say Morton, Mortons, or Morton Salt Company, and all three refer to the same bags.

When comparing prices, match the product by form and weight rather than by the listing title. A "Mortons pellets 40 lb" listing and a "Morton pure and natural 40 lb" listing are the same product.

Morton has sold salt in the US for more than a century, and the softener line grew out of its consumer salt business. The brand is now part of a larger salt producer, and the packaging has changed several times.

What has not changed is the product: solar salt, compressed into pellets or sold as crystals, with a few additive blends. The brand recognition is why the bags are in every hardware store.

That recognition is also why the price holds. A store-brand pellet at $7 and a Morton pellet at $10 are the same mineral, and the difference is the label and the screening.

Pick up two bags and read the back. Compare the sodium chloride percentage, the weight, and the additive line. If those three match, the cheaper bag is the better buy.

Check the pellet uniformity. A bag with a lot of dust and broken pellets will dissolve unevenly. Shake it gently; a bag that sounds like sand has more fines.

Check the date or lot code if present. Salt does not expire, but older stock has had more time to absorb moisture in a humid stockroom.
