There are 3 pieces of 2.5 in. Compatible with iSpring RCC7 and other RO filter systems. NSF and ANSI certified for filtration, durability, and material. Lasts for 6 months for effective filtration. LittleWell 10 in.
The best quality filters for a crystal clear and tasteless water. I have tried other brands that look similar but the difference is noticeable on the water taste. Totally recommend Ispring water filters.
