By reducing the sediment load, it helps maintain consistent filtration performance and supports the life of your RO system. Each cartridge features a standard 10-inch length, 2.5-inch diameter, and making it compatible with most standard 10-inch pre-filter housings used in domestic RO water purifiers. The durable high-density construction provides reliable sediment filtration for homes, offices and commercial water purification systems. This Pack of 4 replacement cartridges is easy to install and is suitable for regular maintenance of your RO system. For best filtration performance, replace the spun filter every 3–6 months, depending on water quality and usage.
