Castalie water, the smoothness of a neutral taste...

\n\n\n

thanks to its microfiltration system, which reduces chlorine, particles, and residues present in the water.

\n\n\n\n

Its neutral taste is particularly appreciated by top chefs and sommeliers, as it pairs well with fine foods and great wines. In its sparkling version, the finesse of the bubbles delights the palates of gourmets.

Microfiltration—
s our expertise

\n\n\n

Microfiltration is a membrane filtration process that removes particles from water that are around one micron in size (100 times finer than the thickness of a hair).

\n\n\n\n

At Castalie, the membrane mesh size is 0.5 microns, one of the finest microfiltration mesh sizes available. In addition to this membrane, Castalie activated carbon into its filters. The role of activated carbon is to remove chlorine from the mains water supply in order to stabilize the bacteriology.

\n\n\n\n

As a result, Castalie water Castalie completely neutral in taste. This carbon also plays an important role in adsorbing heavy metal residues, pesticides, pesticide metabolites, and PFAS, the infamous forever chemicals.

\n\n\n\n

Castalie microfiltration Castalie remove the minerals naturally present in water, in order to guarantee optimal sparkle.

\n\n\n\n

We take care of maintaining the fountain's various filters to ensure optimal and consistent quality.

\n\n\n\n

All our filters are certified by a Health Compliance Certificate (ACS), issued by the Carso laboratory, authorized by the Ministry of Health, in accordance with Article R. 1321-52 of the Public Health Code.

    To understand in a few lines how a micro-filtered water fountain works, visit the dedicated page: how a water filter fountain works.

    \n\n\n\n

    Our filter combines a 0.5-micron membrane and powdered activated carbon. The membrane retains all particles larger than 0.5 microns that may be present in tap water, such as traces of heavy metals, dyes, and drug residues.

    \n\n\n\n

    Activated carbon powder, suspended at the bottom of the filter, traps chlorine present in the water supply through a process of adsorption (chlorine molecules attach themselves to the activated carbon).
