Improve the quality and consistency of cold and hot beverages with the Pentair Optipure CTO-20B Filter Cartridge. This cartridge reduces maintenance costs and extends equipment life through gradient-density depth filtration, effectively removing dirt, rust, and particles as small as 0.5 microns to ensure clean water and protect components from wear and blockages. Activated carbon filtration enhances water taste and prevents equipment damage from chlorine, making it suitable for coffee and tea applications. The cartridge's high capacity extends the filter system's lifespan, reducing replacement frequency and waste compared to traditional filters. It also offers a cost-effective replacement option with lower per-gallon costs than proprietary quick-change filters.
