Comparison BRITA Maxtra Pro 1x vs BRITA Maxtra+ Universal 1x

The resource of a cartridge is the amount of water that it can effectively pass through itself and clean without loss of working qualities. For reusable models (see below), the resource between cleanings/regenerations is usually indicated.

This parameter allows you to estimate how long the cartridge will last and how often it will need to be changed or cleaned. There are formulas that allow you to calculate the approximate water consumption depending on the number of people in the family and other factors; these formulas can be found in special sources. However, manufacturers themselves often make approximate calculations and indicate the frequency of replacement in the documents for a filter or cartridge: for example, “when used in a family of 3 people, change every month”. In fact, it is more convenient to use these recommendations.
