The attractive part is the published capacity and filtration data. The alkaline and antioxidant positioning should be treated separately from contaminant-reduction evidence.
Core specifications
Alkanatur lists a 1.4-liter pitcher, about four minutes to filter one liter and a 400-liter cartridge life. The company says the filter adds around 18 mg/L magnesium and raises pH to roughly 9.5.
Filtration claims
The company describes coconut activated carbon and ceramic/mineral media and publishes broad reduction claims for chlorine, fluoride, pesticides, nitrate/nitrite and multiple metals.
For health-related contaminants, WaterVerdicts would still prefer exact independent laboratory documentation and named standards where available.
Cost per liter
Alkanatur advertises roughly €0.05 per liter based on cartridge capacity. Actual cost depends on replacement price and whether the cartridge reaches 400 liters under the household water conditions.
Geographic fit
The product offeringme is Spain-focused and provides a 10% customer discount code with a 30-day attribution period. This makes the page most commercially relevant for Spanish traffic.
