Introduction: This study aimed to determine whether the degradation of ascorbic acid in aqueous solutions could be used to compare the filtration efficiency of various household water filter jugs.Materials and methods: Based on absorbance measurements of ascorbic acid, a new water quality coefficient (WQC) parameter was defined. Differences between the WQC were determined for 4 different water filters commonly used in household water filter jugs in Poland. In addition, correlations between the WQC, the amount of filtered water (AFW), and a number of other parameters were examined for all 4 filters.Conclusions: Significant differences were found in WQC among the 4 filters. A decreasing efficiency of calcium ion removal from the water was observed with the ongoing use of all 4 filter cartridges. Overall, this method could be a sensitive, simple, fast, eco-friendly, and relatively inexpensive tool for determining the effectiveness of water purification in household water filter jugs, which of course requires further research.
