This guide helps home users choose the right replacement cartridge for a water filter jug. We compare Aquaphor A5, A5 Mg, Maxfor+, Maxfor+ H and compatible oval-fit cartridges, with practical advice for drinking water, tea, coffee, cooking and hard-water areas.
Which filter jug cartridge should you choose for your home?
If you already have a water filter jug, the most important choice is not the jug itself but the replacement cartridge. The right cartridge improves the taste and smell of tap water, helps reduce common impurities and can also help with limescale or magnesium enrichment, depending on the model.
| Your jug type / home need | Recommended cartridge | Best for |
| Aquaphor round-fit jugs such as Provence, Prestige, Atlant, Smile and compatible models | Aquaphor A5 | Everyday home drinking water, tea, coffee and cooking |
| Round-fit Aquaphor jugs where magnesium enrichment is preferred | Aquaphor A5 Mg | Better-tasting water with magnesium enrichment |
| Oval Maxtra-style jugs, including many Aquaphor, Brita Maxtra-style and compatible pitchers | Aquaphor Maxfor+ | Universal oval-fit replacement for many home filter pitchers |
| Homes with medium-hard or hard tap water | Aquaphor Maxfor+ H | Reducing limescale taste and protecting kettles and coffee machines |
Tip: if your old cartridge was Aquaphor B5, choose the newer Aquaphor A5 or Aquaphor A5 Mg for compatible round-fit jugs.
In previous articles, we discussed why drinking water from the tap is often filtered at home and what characteristics to consider when choosing a water filter jug. Now we will focus on the part that does the real work: the replacement cartridge.
