Two approaches to tap filtration
Standard filters are the most common models on the European market. They attach directly to the tap and typically use a single filtration stage of activated carbon.
Puramane is a French brand based in Fontenay-aux-Roses (92). Its tap filter features 8 filtration stages combining activated carbon, ion-exchange resin and UV sterilisation, all powered without batteries by hydraulic energy.

Our verdict
A standard filter is a good entry-level product. If your main goal is chlorine removal on a minimal budget, it does the job.
However, if you want more thorough filtration, lower cost per litre long-term and a product with no battery and infrequent cartridge changes, Puramane offers better value in the medium to long term.
Summary: A standard filter suits a first trial. Puramane is the rational choice for performance, economy and sustainability.
Frequently asked questions
Which tap filter offers the best value for money?
The Puramane filter costs 0.02 euros per litre thanks to its 2,000-litre cartridge (24.90 euros per pack of 2). A standard filter costs roughly 0.05 euros per litre with a 600-litre cartridge. Over a year, the difference is significant.
Does the Puramane filter need batteries?
No. The Puramane filter runs without batteries thanks to hydraulic energy generated by the water flow. The LED display lights up automatically. Standard filters often use a coin cell for their indicator.
Does a standard filter work as well as the Puramane?
A standard filter typically uses a single-stage filtration system (activated carbon). The Puramane combines 8 filtration stages including activated carbon, ion-exchange resin and UV sterilisation. Both filter chlorine, but the Puramane offers more comprehensive filtration.
