They use available methods of purifying tap water, which, in addition to the positive aspect of removing secondary contaminants, can also lead to the removal of minerals important for human health. This is the case with water hardness, which is negatively assessed through the prism of scale in the kettle or on the fittings. However, reducing the value of this parameter in home water purification systems eliminates calcium and magnesium ions from the water, which have a major impact on the functioning of the human body. Studies conducted in many countries indicate that drinking hard water is not a threat to health, but rather constitutes its good condition. In the article, the authors checked in the laboratory how water hardness changes as a result of using selected jug filters. The obtained results indicate that most of the tested filter cartridges soften water in the first phase of operation to a level below the requirements for drinking water, additionally acidifying it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Keywords:<\/strong> tap water, secondary contamination, water hardness, filter jug, magnesium<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Bibliografia<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">[1] Adamski W.2014. \u201eStan i trendy w rozwoju technologii oczyszczania wody\u201d, Tech.
