Granular activated carbon filters purification for potable water treatment (GAC purification foam)

Granular activated carbon (GAC)is a hybrid mixture of a wide variety of graphite platelets that are interconnected by nongraphitic carbon bonding. The adsorptive capacity of GAC makes it ideal for removing a variety of contaminants from water, air, liquids and gases. GAC is also an environmentally responsible product that can be reactivated through thermal oxidation and used multiple times for the same application.


  • Raw material: open-cell polyether and cocoanut activated carbon
  • Porosity: 10~30 PPI (GAC Filter Foam)
  • Activated carbon types: Granular activated carbon(GAC)

Cell Structure:

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

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

10 PPI – 35 PPI pore densities, approximately full scale


Activated carbon filter foamcan be widely used in daily life and industry such as 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.It’s divided into beginning effect filter foam,amid effect filter foam and high effect filter foam according to the porosity and usage.Concretely,it can be used in Chlorine,Taste, & Odor Removal, Reverse Osmosis Applications, Filtering, Dustproofing, Dedusting and Adsorbing,etc.

Our sales team works closely with you to understand your products, business and vision. We review both internal and external factors, from product information to environmental factors involved in production, packaging and testing requirements. We form well considered opinions as a basis for recommending, improving and strengthening your products, before choosing the right format and manufacturing base.

Once our sales team has gathered all the information we then hand the project over to our sourcing team who will look carefully at the project needs and objectives to find the right location to manufacture the goods. They will look at issues of price, quality and delivery times before making a decision.

International companies also require a high standard of social, ethical and environmental compliance which must be passed on to their customers.

Master Sponge can therefore offer a full through the line service from designing and developing new products, through the stages of mass production, packing and delivery to the clients doorstep.×
At Master Sponge we understand the need for strict quality guidelines to be imprinted into our organizational structure. China has a distinct lack of professionalism when it comes to issues of quality. With our quality control office sustained by professionally trained staff, overseen directly by our senior management and located in the heart of the manufacturing district; we are able to demand the highest standard of quality from our suppliers.

Quality starts with organization; we have many factories wishing to work with us but are very selective when choosing them. We send our trained audit technician who will look round the factory to assess whether it can pass international ethical & social inspections. Once this is done we will look at the machinery and make sample products to ensure the quality and manufacturing process is to our standards. We then talk to the management to assess whether or not they are people who we can discuss and solve complex problems with.

Once this is complete we will begin to produce products by placing our own Quality Control representative to oversee all production.×
