CFS Carbon Block Water Filters – 4 Pack – 1 Micron – 10" x 2.5" – Fits SpectraPure RO/DI

This CFS 1 micron coconut shell carbon block is built for the prefilter position in a reverse osmosis or RODI system — it takes out the chlorine that destroys thin film composite membranes before water reaches them. Standard 10" x 2.5" sizing drops into SpectraPure housings and most systems built around standard cartridges. At 1 micron it is finer than most prefilter carbon, so it also retains fine particles that would otherwise reach the membrane surface.

• 4 cartridges per pack
• 1 micron coconut shell carbon block
• Standard 10" x 2.5" size
• Protects RO and RODI membranes from chlorine
• Stack order: sediment first, carbon second, membrane third, DI last
