Activated Carbon Filter Foam Sponge Sheet


Filter foam sponge, also known as reticulated sponge, is a porous, low-density, reticulated flexible polyester/polyether urethane sponge. With an open cell structure and three dimensional skeletal strand structure. 


The open cell sponge specifically manufactured for aquarium and pond use has a much larger inner surface area for beneficial biological capacity than the cheap close cell sponge in the market. The reticulated structure also provides better flow rate of water and less chance of clog. 

You can use it in any aquarium or pond filter, sump, wet/dry, canister, power filter etc. or your HMF DIY project. It can be trimmed to any size with a utility knife. 

The size of pores is measure in pores per inch (PPI). The sponge with higher PPI has more pores in it. More pores means larger biological filtration capacity but with less water flow through rate and needs to be cleaned more often. It is recommended to use combination of sponge with difference PPI to get the best result.



Product Description


Filter sponge can be widely used in daily life and industry such as aquarium or pond filter,communication equipment,home appliances,automotive industry, air-conditioner industry,hardware industry,medical equipment industry,instrument tools,bags,furniture,children’s educational toys,physical education equipment, house wares and so on.



1. The material has great thickness, it is durable.

2. Very suitable for using in freshwater and marine wate
3. Good water permeability.
4. Easy to install over the filter intake.
5. For preventing small fish from being sucked into the filter.
6. Provides biological and chemical filtration and increase the oxygen solubility in aquarium and fish tank.
7. Dense honeycomb shape makes it effective to avoid residue and reduce the death rate of fish.


1. You can cut the size as you need.
2. A small rubber band can be used to close off bottom of sponge if strainer has openings on bottom.
3. Can be used again after cleaning.

1. The material has great thickness, it is durable.

2. Very suitable for using in freshwater and marine water.

3. Can be cut any sizes as your needed.

4. Lightweight and softness design.

5. Excellent water permeability. Cultivate the nitrifying bacteria for biological filtration.

6. Dense shape makes it effective to avoid residue. Can be used again after cleaning.

7. The biochemical filter has the best effect on decomposing the excrement and the forage leftover.

8. Its multi-porous feature will avoid blockages and provide the largest adhesion area for bacteria.

Filter sponge, also known as reticulated sponge, is a porous, low-density type of polyurethane sponge with an open cell structure. Filter sponge has a near-infinite amount of applications due to the following characteristics:


· Compressibility

· Energy absorption

· Fabricatibility

· Flexibility                       

· Lightweight

· Low thermal conductivity

· Low water vapor transmission

· Mildew-resistance

· Resiliency

· Sound absorption

· Vibration dampening





Cell Structure



Filter sponge operates as a depth-loading filter, as opposed to a surface-loading filter, essentially trapping dust particles within its cells.


The cell structure of filter sponge is remarkable in that each cell has a dodecahedron shape (12 sided), the cell’s walls or “struts” are comprised entirely of organic polymers (polyurethanepolyetherpolyester) & the empty space or “windows,” between each strut, comprise 95% - 98% of the filter sponge’s mass.


The size, shape & distribution of cells within filter sponge can be manipulated during manufacture to provide precisely the desired porosity level, measured in PPI or pores per inch.
