Which Cartridge Size Do I Need?
Before ordering, check the size of your existing filter housing or cartridge.
| Housing size | Replacement cartridge size |
|---|---|
| 10” Big Blue housing | 10” x 4.5” cartridge |
| 20” Big Blue housing | 20” x 4.5” cartridge |
Big Blue refers to the wider 4.5-inch diameter cartridge format. Standard slimline cartridges are narrower and may not be suitable for Big Blue housings.
