Dimension: 16″ Lx 12″W x 1″H, PPI: 40. Includes 2 pieces of open cell sponges
The open cell sponge has a much larger inner surface area for filtration
This filter pad can be cut to fit and used as a pre-filter for any aquarium or pond filter, sump, wet/dry, canister, power filter etc. or your HMF DIY project
The reticulated structure also provides better flow rate of water and less chance of clog
This filter sponge pad can last a long time. The dense structure of our sponge filter foam pad media prevents tearing, making them easy to clean and reuse.
