Knowing the service life of each filter cartridge helps customers reduce after-sales problems and repeat orders steadily.
PP cotton filter generally lasts 3 to 6 months, easily blocked by sediment and rust. UDF and CTO carbon filters can work 6 to 12 months, affected by raw water quality. The RO membrane in 5-stage filtration systems can last 2 to 3 years under good pre-filtration protection.
Areas with high sediment, high hardness and poor tap water need shorter replacement cycles. Regular replacement of the 3-in-1 pre-filtration set can greatly extend RO membrane life.
As a professional manufacturer, we provide complete replacement filter kits and bulk wholesale support for global agents and distributors.
