SpiroPure SP-PH-20 Polyphosphate Filter 20x2.5 Anti-Scale Water Filter

The SpiroPure SP-PH-20 Polyphosphate Anti-Scale Filter Cartridge prevents scale and corrosion in your plumbing, pipes, fixtures, and appliances, as well as reducing the buildup of previously formed scale. SP-PH-20 is a high quality replacement filter that fits any standard filter housings that use 20" x 2.5" filter cartridges.

Benefits:

• Polyphosphate inhibits the formation of scale deposits and rust build-up from forming in pipes and on fixtures
• Forms a protective coating that safeguards against acidity, alkalinity, hardness, chloride, and other causes of corrosion and hardwater deposits
• Dissolves metals and sequesters them (keeps them suspended in water) to prevent unwanted discoloration and staining from water, such as that cause by iron, manganese, calcium, aragonite, and magnesium
• Maintenance free: No purchasing salt, regeneration cycles, or harmful wastewater; simply replace the filter cartridge
