Choosing the right filter - which filter cartridge is the right one? Having the choice is often a difficult decision.
We are often asked which filter cartridge would actually be the right one.
Basically, all of the following Carbonit filter cartridges fit into all Carbonit Sanuno, Vario and DUO filter housings due to their design. However, choosing the right Carbonit filter cartridge is indeed crucial for optimal drinking water quality. Carbonit filter cartridges differ from other available filter cartridges in particular due to two key filter properties.
On the one hand, the filter cartridge's sieving effect creates purity for undissolved substances such as suspended matter, sediment, germs and bacteria. This "sieve" holds back all particles and contaminants via the respective size of the pore openings (similar to a sieve) and is specified in nanometers (nm).
On the other hand, the adsorption effect of the activated carbon removes dissolved pollutants (polar pesticides, agricultural residues, chlorine, drug residues and much more). The ability to adsorb these pollutants is becoming increasingly important due to increasing environmental pollution. It is called adsorptive retention. The adsorptive retention rate (AAR) indicates how high the retention is in comparison to the Carbonit NFP Premium filter cartridge.
Conclusion:
The standard Carbonit NFP Premium filter cartridge is the optimal combination of sieving effect and adsorption effect and is ideally suited to filtering drinking water. Its high proportion of activated carbon and the low water flow ensure that all dissolved pollutants are safely removed. As a rule, the Carbonit NFP Premium filter cartridge should therefore be used.
However, since the flow rate is limited to around 2 liters per minute, the Carbonit NFP Premium filter cartridge is only suitable for filter systems that differentiate between filtered water and domestic water (Sanuno or Vario/DUO with separate fittings for filtered water or 3-way fittings). If you have installed a Carbonit drinking water filter directly in the cold water pipe, i.e. filtering all cold water, you will need a faster flow rate. For this purpose, you will find a variety of filter cartridges that combine a membrane for the sieving effect and activated carbon for adsorptive retention, thus ensuring a faster flow rate.
In some cases, e.g. when the water pressure is low or there is a lot of contamination, the use of a combination filter cartridge is usually unavoidable. We would be happy to advise you individually on this.
