Certified: WRAS , WQA , LUCIDEON

Dimensions: 205 x 45 mm

The Ultra Sterasyl ceramic-carbon filter is the result of two centuries of research and innovation in the field of fine filtration, by the inventors of gravitational filtration .

Ultra Sterasyl filter => 4 levels of water purification:

1. Ceramic exterior: microfiltration (0.2 micron) of pathogenic organisms (bacteria, parasites, cysts, etc.), sediments and impurities (turbidity) > 99.999%

2. Interior of the ceramic: anti-bacterial formula, avoids any internal microbiological development

3. Granulated activated carbon: Elimination of bad tastes, odors, chlorine, chlorinated derivatives > 94%. Residues and chemicals > 80% (herbicides, pesticides, atrazine, phenols, trialomethanes, aromatic hydrocarbons, etc.). Residues from personal care products and medications > 80%

4. Anti-heavy metal media: Reduction of heavy metals and pesticides (lead, glyphosate, etc.) > 99.9%


  • Perfluorinated compounds (PFAS): eternal pollutants
  • Bacteria and cysts
  • Chlorine and chlorinated derivatives
  • Heavy metals (lead and aluminum, etc.)
  • Drug and hormone residues
  • Chemical products (pesticides, insecticides, herbicides, etc.)
  • Neutralizes bad odors and bad taste of water
