ScaleArmor POP limescale filter: whole-house point-of-entry protection without salt, chemicals or phosphates. 3/4″, up to 1500 l/h. €145.00.

The ScaleArmor POP limescale filter is a "Point Of Entry" system for the main cold-water supply. According to the seller, it protects pipes, fittings, water heaters, coffee machines, dishwashers and washing machines from limescale. It works without salt, chemicals or phosphates and, as stated, is suitable for homes, apartments and commercial buildings. The compact design is said to suit small spaces, and installation is described as quick and simple.

According to the manufacturer, a special technology in the ScaleArmor POP limescale filter slows the growth of calcium and magnesium carbonate crystals, so limescale is reduced. The beneficial minerals calcium and magnesium are said to stay in the water. The seller also states lower energy use, better flow and longer life of boilers and appliances. The page gives no measured figures or test conditions for these claims, and no certificate or efficiency value for the POP model.

The package contains the housing, the ScaleArmor cartridge, a wall bracket, a key, an O-ring and instructions; the specification list also names a lubricant, which the descriptive paragraph omits. The replacement ScaleArmor POP refill costs €73.90. The English POP datasheet (PDF) is available on the page.
