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.

| 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.
