- The patented ribbed backing creates an even distribution of activated carbon and maximum water-to-carbon contact for clearer water.
- Double thick poly-fiber traps debris and waste particles and lasts for up to 2-4 weeks.
- Slides easily into place making replacement fast, dry and effortless.
- Compatible with all Emperor BIO-Wheel filtration systems.
