Siliphos Refillable Cartridge – 20" Big Blue | Anti-Scale & Anti-Corrosion Filter

Reliable Water Treatment for Corrosion & Scale Protection

The 20" Big Blue refillable cartridge is the ultimate solution for scale and corrosion prevention in large households, commercial premises, and high-demand water systems.

Siliphos is a high-performance, food-grade polyphosphate-based media designed to prevent scale build-up and corrosion in potable and industrial water systems. Manufactured from 100% pure sodium hexametaphosphate, this NSF Certified solution is suitable for use in homes, commercial buildings, and industrial plants.

Key Features:

• NSF Certified for safe use in drinking water systems.

• Prevents Hardness Scaling by interfering with crystal growth.

• Reduces Corrosion in pipes, geysers, boilers, and fixtures.

• Protective Layer Formation of iron-calcium-phosphate on internal pipe surfaces.

• Food-Grade Composition: Safe, non-toxic, and environmentally friendly.

• Highly Economical: Long-lasting spheres slowly dissolve over time.

Applications:

• Domestic plumbing and geysers

• Hotels, restaurants, public facilities

• Commercial buildings

• Industrial water supply systems

• Equipment protection in heat exchangers, chillers, and boilers

How It Works:
Siliphos media dissolves gradually as water flows over the spheres inside a suitable filter housing. This controlled dissolution releases polyphosphates into the water, sequestering minerals and preventing the formation of deposits and rust-coloured water often associated with iron oxidation. The spheres also inhibit corrosion by forming a stable, invisible protective layer on internal surfaces.
