Which salt blocks does Nederlandse Zouthandel offer?

We deliberately carry two brands of salt blocks: nedzal® and Axal. Together they cover the two most common formats and offer you the assurance of A-quality block salt.

  • nedzal® salt blocks 4 kg

    nedzal® salt blocks of 4 kg are made from high-purity salt and contain no additives that could damage the resin of your water softener. Each pack contains two blocks of 4 kg (8 kg total). Thanks to the ergonomic design, you can lift and place each block easily with one hand.


    Features of nedzal® salt blocks:

    • High-purity salt, optimal for the performance of your water softener
    • Convenient 4 kg blocks — no struggling with heavy bags
    • 2 blocks per pack (8 kg total)
    • Suitable for all water softeners that use 4 kg blocks
    • nedzal® also offers salt tablets and resin cleaner, for those who prefer a complete range from a single brand
  • Axal salt blocks 2.5 kg

    Axal is an established A-brand, known for its consistently high quality. The Axal salt blocks of 2.5 kg are a reliable choice for water softeners that use this format. Each box contains 4 blocks (10 kg total).


    The salt has a sodium chloride content of virtually 100%, ensuring the blocks dissolve in a controlled manner without leaving residue in the salt tank.


    Features of Axal salt blocks:

    • Sodium chloride content of virtually 100% NaCl
    • Dimensions: 20 x 10 x 7.5 cm per block

What are salt blocks used for at home?

Salt blocks have one primary application: regenerating your water softener, so you can enjoy soft, limescale-free water throughout your home. In large parts of the Netherlands and Belgium, tap water is hard to very hard — and you notice it almost everywhere water is used. With a well-stocked water softener, every room in your home benefits from the comfort of soft water.

  • keuken-zoutblokken

    In the kitchen

    In the kitchen, softened water makes a visible difference on almost every appliance and surface. Your dishwasher runs more efficiently and glassware comes out of the machine without limescale streaks.


    Coffee makers, espresso machines and kettles need descaling far less often and demonstrably last longer. Taps and sinks also stay spotless for longer, without constantly reaching for the cleaning cloth.

  • badkamer-zoutblokken

    In the bathroom

    The difference between hard and soft water is especially noticeable in the bathroom. Shower screens, tiles, taps and mirrors stay clean much longer, as limescale barely has a chance to form.


    In the shower, you'll find that soap and shampoo lather much more easily, so you need less product. Many users also notice softer skin and more supple hair, particularly if they are sensitive to the limescale in tap water.

  • wasmachine-zoutblokken

    For laundry

    Your washing machine is one of the biggest beneficiaries of soft water. Because detergent dissolves fully and limescale cannot attack the heating elements, your machine runs more efficiently and lasts longer.


    Your laundry also feels noticeably softer, and clothing and towels wear out more slowly. Many households find they can get by with significantly less detergent.

  • cv-ketel-zoutblokken

    Heating and hot water

    Limescale build-up in your boiler, water heater or combi boiler acts as an insulating layer on the heating elements. As a result, your system has to work harder to produce the same hot water, leading to higher energy bills.


    With softened water, these elements stay clean and your heating system retains its original efficiency. This extends the lifespan of your installation and saves you directly on energy costs.

  • How does the delivery of salt blocks work?

    Timely delivery is essential: an empty water softener means hard water in your home or business straight away. We therefore apply the following delivery conditions.

Frequently asked questions about salt blocks

  • A water softener contains ion exchange resin that removes calcium and magnesium ions — the cause of limescale — from tap water. Over time, this resin becomes saturated and needs to be regenerated. To do this, the water softener uses a brine solution made by dissolving the salt blocks in the salt reservoir. The brine flushes the resin clean, after which it can absorb limescale again. Salt blocks are therefore essential for a properly functioning water softener.

  • Lime-free water offers many benefits: no limescale build-up on taps, shower heads, glassware, and tiles; a significantly longer lifespan for your washing machine, dishwasher, coffee maker, and central heating boiler; softer laundry that wears out less quickly; reduced use of cleaning products and detergent; and lower energy costs thanks to clean heating elements. In addition, many people immediately notice greater comfort when showering.

  • Consumption depends on the hardness of your tap water, water usage, and the capacity of your water softener. An average four-person household in a hard water area uses roughly 50 to 75 kg of salt per year. One pack of Nedzal 4 kg (8 kg total) or a box of Axal 2.5 kg (10 kg total) typically lasts one to two months.

  • Salt blocks have an almost unlimited shelf life as long as they are stored dry. If you do not store the blocks in a damp environment, they will remain usable for years.
