BWT Perla Cubes Water Softener Salt Tablets – 25 kg Bag are high‑purity salt tablets designed for regenerating ion‑exchange water softeners in homes and commercial settings.

Below is a clear, practical explanation of what they are and what they’re used for.

What they are

BWT Perla Cubes (often also sold as BWT Care Cubes or Perla Tabs) are compressed sodium chloride (NaCl) tablets made specifically for water‑softening systems. They are supplied in a 25 kg heavy‑duty bag and are suitable for almost all brands of water softeners, not just BWT models.

What they do

Water softeners work by using resin beads to remove hardness minerals (calcium and magnesium). Over time, the resin becomes exhausted and must be cleaned through a process called regeneration.

BWT Perla Cubes:

• Dissolve in the brine tank
• Create a brine solution
• Regenerate the resin so the system can continue softening water efficiently

Key features

High purity salt

• Typically, 99.6–99.9% pure sodium chloride
• Made from vacuum‑dried salt for consistent quality

Food‑grade quality

• Complies with BS EN 973:2009 (Grade A), the recognised standard for water treatment salt
• Iodine‑free and free from anti‑caking additives, which helps protect the softener mechanism

Tablet (cube) format

• Tablet shape prevents salt bridging and sludge build‑up
• Dissolves at a controlled rate
• Cleaner and easier to handle than loose granular salt

What systems they’re suitable for

BWT Perla Cubes are:

• Suitable for all domestic water softeners
• Commonly used in commercial and catering environments (restaurants, bars, cafés)
• Compatible with dishwashers and heating appliances that rely on softened water

They are especially recommended for BWT Perla systems but work just as well in other manufacturers’ units.

Benefits of using them

Using BWT Perla Cubes helps to:

• Maintain consistent soft water
• Reduce limescale buildup in pipes, boilers, and appliances
• Extend the life of your water softener
• Improve efficiency and reduce maintenance issues
