BRITA Marella Water Filter Jug White (2.4L) Starter…

The BRITA Marella's standout is its digital indicator, which measures water filtered litre by litre and tells you precisely when the cartridge needs replacing, removing the guesswork that comes with jugs relying on a rough weekly estimate. It ships with three MAXTRA PRO cartridges rather than just one, giving several months of filtering before restocking is needed, and the flip-lid design makes topping up at the tap straightforward even with limited space. Rated 4.7 stars from close to 7,000 reviews, it's one of the most thoroughly tested filter jugs available.

The 2.4-litre capacity is comfortable for most households, though larger families or heavy water drinkers may still find themselves refilling more than once a day compared with bigger jugs on the market. BRITA's packaging has moved to a more sustainable Smart Box format, a small but genuine plus if that matters to you. Priced £17–£33.80, the inclusion of three cartridges rather than one makes it reasonable value against jugs sold with less filtering capacity included from the outset.
