BRITA Marella XL Water Filter Jug Blue (3.5L) incl. 1x…

The Marella XL's standout compared with BRITA's standard jug is its larger 3.5-litre capacity, which means noticeably fewer trips back to the tap for larger households or anyone who gets through a lot of water day to day. It carries over the same digital litre-by-litre indicator that tells you precisely when the cartridge needs replacing, and the flip-lid design makes refilling straightforward even in kitchens with awkward sink setups. Rated 4.6 stars from close to ten thousand reviews, it's one of the most extensively tested filter jugs on the market.

The trade-off for the larger capacity is that it ships with just one MAXTRA PRO cartridge rather than the multiple cartridges some smaller BRITA jugs include, so budget for a replacement fairly soon after your first month of use rather than assuming you're covered for several months out of the box. The cartridge itself performs the same limescale and chlorine reduction as elsewhere in the range. Priced £13–£27, it's a sensible option for families or heavy water drinkers who value fewer refills over having spare cartridges included upfront.
