Why are carbon block cartridges a good choice?

A block carbon cartridge consists mainly of activated carbon granules and a binding agent that allows the carbon granules to maintain a static position with respect to each other.

It should be noted that in block carbon cartridges, carbon particles are immobilized to promote uniformity of performance, preventing water channeling, which is common with GAC. The carbon block is formed in a cartridge of predetermined dimensions.

It is this uniform pore structure between the individual carbon granules that allows the carbon block to achieve greater pollutant reduction efficiency. The uniform pore structure of the carbon block also increases the contact time with the filter media, which further increases the block’s ability to remove contaminants.

More efficiency due to the particle size of the coal.

The smaller particle size and uniform pore structure of the carbon block cartridge provides a high level of efficiency in a much smaller size than a GAC at the same flow rate. For this reason, GAC is typically used as a treatment method for aesthetic contaminants (removal of taste, odor and color). Carbon block cartridges go beyond aesthetic water improvement by reducing particulates, microscopic cysts, lead, volatile organic chemicals (VOCs) and other contaminants.

Almost no color release (fine).

On the other hand, carbon fines or carbon dust can be a major concern in customer service. The new GAC filters release black color in the water (carbon fines) contained in the carbon when the filter is first used. Due to its static composition, the carbon block produces a minimum of carbon fines at start-up, thus minimizing the need for backwashing or washing.

Furthermore, an additional advantage of carbon block over GAC is that the pore size of the block can be controlled to a size small enough to virtually eliminate bacterial growth within the filter.

Benefits of a carbon block cartridge:

In general, carbon block is a better choice in water filtration applications because of its high effectiveness in removing contaminants, relative low cost, compact size, use of renewable resources, small form factor and resistance to bacterial growth.

  1. Highly effective in the purification of: Chlorine, taste and odor.
  2. FDA listed materials.
  3. Low pressure drop. High performance.
  4. Greater capacity to retain dust and other small particles.
  5. Longer service life than granular cartridges.
  6. Low ash content (coal fines) compared to granular cartridges.


Common applications of carbon block cartridges:

Carbon is commonly used in POU (Point of Use) water filtration in carbon block and GAC applications. However, compared to GAC, the higher efficiency of the carbon block and the higher number of carbon particles allow the carbon block to remove or reduce impurities with a much shorter contact time. In addition, the smaller form factor allows carbon block manufacturers to produce high-performance water filters in much smaller and diverse product designs. Some of the main applications are:

  • Home reverse osmosis system pre-filter.
  • Water filtration in the home.
  • Point-of-use (POU) filtration.
  • Dental laboratories and dental offices.
  • Filtration for the power supply of household appliances, such as refrigerators.
  • Water filtration for small businesses.
  • Water from the municipal water supply.
  • And a wide variety of other applications.
