The large housing and cartridge units offer up to 35 GPM of flow at 60 PSI and the maintenance costs for larger cartridges is much lower than replacing smaller cartridges more frequently. These housings are low cost, durable, easy to install and they accept standard Big Blue size filter cartridges.
