Each filter treats 400 L (110 gallons), about 3 months of regular use. An Annual Pack includes 4 filters, about a year.

About Alkanatur alkaline water pitchers
Alkanatur alkaline water filter pitchers turn ordinary tap water into filtered, alkaline, mineral-rich water at home. Made in Spain and developed with the University of Galicia, each pitcher uses a natural coconut carbon and bioceramic filter, without ion-exchange resins, so no sodium is added. The water reaches a pH of 8.5–9.5, keeps its calcium and potassium and gains magnesium.
Choose the pitcher with the Standard filter for everyday tap water, the Low Magnesium Emission filter for hard water, or the Enhanced filter for older plumbing. Pick an Annual Pack to get a year of filters with your pitcher.
