Double 20" Big Blue Filter Set: 1 Micron & Siliphos Cartridge 

What is SILIPHOS?

SILIPHOS is an economical and reliable water treatment system for potable and industrial water. It consists of glass-like polyphosphate silicate spheres and dispensers of variable size.

 
SILIPHOS prevents scale and stops corrosion. It utilizes the phenomenon that minute concentrations of polyphosphates are sufficient to inhibit the deposition of scale onto metallic surfaces. Because of its phosphate and silicate content, SILIPHOS also inhibits corrosion by forming a thin protective layer on the metal surface. A SILIPHOS concentration of 2 - 3 ppm is sufficient to achieve both of these effects. Please find more information on siliphos at the following link.

Additional Options 

Change Standard 1 Micron Melted Spray to Antibacterial Option

The Melted Spray Antibacterial filters like the standard melted Spray type are designed to capture dirt, sediments, visible particles, and bacteria.

However, the Melted Spray sediment filters have had a silver ion additive added to their material, which creates a bacteriostatic function to inhibit the growth of bacteria on the surface of the filter, helping to ensure healthier product water and a longer life span of the filter.

This option is ideal for source waters that have a very high bacterial / organism count and will help to extend the life of the filter.
