Open Cell Polyurethane Foam Filter Sponge
| A filter sponge, also known as a 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 |
| 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 mean larger biological filtration capacity but with less water flow through rate and needs to be cleaned more often. It is recommended to use a combination of sponges with different PPIs to get the best result. |
| Filter sponges 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, housewares and so on. |
Top 10 Reasons Why you Choose our Filter Foam:
1. The material has great thickness, it is durable.
2. Very suitable for use in freshwater and marine water.
3. Can be cut in any size as your need.
4. Lightweight and soft 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.
9. A small rubber band can be used to close off the bottom of the sponge if the strainer has openings on the bottom.
10. Can be used again after cleaning, it’s reusable.
It’s divided into beginning effect filter sponge, amid effect filter sponge, and high effect filter sponge according to the porosity and usage. Concretely, it can be used in filtering, dust proofing, dedusting, and adsorbing, etc.
