Description
The carbon block cartridge for the Merlin system is an efficient replacement designed for use in systems such as reverse osmosis systems, osmotic filters, and water filters used for cold water treatment. Made from sintered activated carbon, it helps improve the taste and odor of water, effectively reduces free chlorine, and captures selected organic contaminants and mechanical particles down to 3 µm. It is a practical filter cartridge for the Merlin water filtration system for users who expect good performance and economical operation.

Carbon block cartridge for the Merlin system – effective filtration support
This block carbon cartridge has been designed as a replacement for the Merlin reverse osmosis system. Its task is to improve water quality at the carbon filtration stage by reducing compounds that worsen the water’s usability and by retaining fine mechanical impurities.
The filter media is sintered activated carbon. This design combines high adsorption efficiency with precise mechanical filtration, making the cartridge well suited for applications where both water taste and odor as well as the reduction of fine solid particles matter.
What does this filter cartridge remove and reduce?
The cartridge made of sintered activated carbon removes from water:
- up to 99% of free chlorine,
- chlorinated solvents,
- aromatic hydrocarbons,
- up to 85% of chlorinated pesticides,
- polyaromatic compounds,
- phenol,
- benzene,
- organic substances.
The result of the cartridge’s action is a noticeable improvement in the taste and odor of water. In addition, the filter element retains mechanical contaminants such as:
- rust,
- sand,
- silt,
- suspended solids,
with a size of up to 3 µm.
Why a sintered activated carbon block?
Sintered activated carbon has a much larger specific surface area and a greater number of active centers. In practice, this translates into approximately 25% higher usable efficiency compared with other carbon cartridges. This is an important advantage in everyday operation of a water filtration system, especially where stable performance and effective water treatment matter.
The block form of the cartridge supports simultaneous reduction of contaminants affecting the organoleptic properties of water and the capture of mechanical particles. As a result, the cartridge is an important component of the filtration set in the Merlin installation.
Application
The cartridge is intended for the Merlin system and is an excellent-quality replacement for the original cartridge. It is adapted for cold water treatment, so it should operate only within the recommended temperature range.
The cartridge is intended for cold water. The service life of the filter element depends on the quality of the filtered water and the degree of contamination, so the actual service life may vary depending on operating conditions.
Main benefits
- replacement for the Merlin reverse osmosis system,
- made of sintered activated carbon,
- improves water taste and odor,
- reduces free chlorine and selected organic contaminants,
- retains mechanical particles down to 3 µm,
- approx. 25% higher usable efficiency compared with other carbon cartridges,
- intended for cold water treatment.
Operation and replacement
For the reverse osmosis filter to work effectively, the cartridge should be replaced regularly. The recommended service life is 3 to 6 months. Replacement frequency depends on the quality of the feed water and the amount of contaminants present in it.
If the water has a noticeably higher level of mechanical contaminants or a strong chlorine odor, the service life may be shortened. Regular inspection of the water filtration system helps maintain high treatment efficiency and stable system performance.

Questions
Which system is this cartridge compatible with?
This is a replacement intended for the Merlin reverse osmosis system. It is used as a block carbon cartridge in this type of filtration installation.
What contaminants does the block carbon cartridge remove?
The cartridge reduces up to 99% of free chlorine, chlorinated solvents, aromatic hydrocarbons, as well as up to 85% of chlorinated pesticides, polyaromatic compounds, phenol, benzene, and organic substances. It also retains mechanical contaminants down to 3 µm.
Does this cartridge improve water taste and odor?
Yes. Thanks to the use of sintered activated carbon, the cartridge effectively reduces compounds responsible for unpleasant taste and odor, especially those related to the presence of chlorine and selected organic contaminants.
Is this cartridge suitable for hot water?
No. The cartridge is intended for cold water treatment and should operate within a temperature range of 2°C to 45°C.
How often should the cartridge be replaced?
The recommended service life is 3 to 6 months. The actual service life depends on water quality and the level of contamination.
What mechanical particles does this filter cartridge retain?
The cartridge retains, among others, rust, sand, silt, and suspended solids up to 3 µm, supporting proper operation of the entire water filtration system.
What does the use of sintered activated carbon provide?
Sintered activated carbon has a larger specific surface area and a greater number of active centers, which translates into approximately 25% higher usable efficiency compared with other carbon cartridges.
Is this an original cartridge or a replacement?
This is a high-quality replacement for the original Merlin system cartridge, intended for the same filtration function.
