10 Best Water Purifiers 2025 in the UK

The BRITA Marella Water Filter Jug in Graphite combines innovative filtration technology with user-friendly functionality. It uses the MAXTRA PRO 4-stage filtration system, which effectively reduces impurities like chlorine, limescale, lead, and copper, enhancing the taste and safety of your drinking water. This system also promises reliable protection against limescale, which is beneficial for those living in areas with hard water.

With a capacity of 2.4 liters, this jug is well-suited for small households or individuals and conveniently fits in standard fridge doors. The product includes three filter cartridges, each lasting approximately 150 liters or four weeks, making maintenance relatively low-effort with the help of the digital Lifetime Indicator that reminds users when to change filters.

The design is both practical and sustainable, featuring a flip-lid for easy filling and a spout cover to protect from dust. The jug is BPA-free and dishwasher-safe, except for the digital indicator, ensuring ease of cleaning and safety. However, one potential downside is the limited water capacity as it only provides 1.4 liters of fresh filtered water at a time, which may not be sufficient for larger families or high water consumption needs.

While this jug is ideal for those seeking an easy-to-use and space-efficient water filtering solution, it may not fit those who require a larger volume of filtered water continuously. Additionally, the compatibility with BRITA's MAXTRA PRO filters ensures optimal filtration, though users should be aware of the ongoing cost and effort involved in purchasing and recycling the cartridges.

Environmentally conscious users will appreciate that using this jug can significantly reduce reliance on bottled water, decreasing plastic waste and carbon footprint. The BRITA Marella jug presents a robust option for anyone looking to improve the quality of their drinking water while maintaining convenience and sustainability.

The BRITA Marella XL Water Filter Jug is a user-friendly and eco-conscious solution for clean drinking water. It uses the MAXTRA PRO All-in-1 cartridge which filters up to 150 liters of water in 4 weeks, making it excellent for households with high water consumption. The jug’s 3.5-liter total capacity, providing 2 liters of filtered water, suits larger families or frequent use. Its BPA-free material and dishwasher-safe design (excluding the digital indicator) make it convenient to maintain.

The flip-lid enables easy one-hand filling, and the digital lifetime indicator reminds you when to change the filter, ensuring continuous optimal filtration. This jug is equipped with a spout cover to protect water from dust and impurities, and the perfectfit feature guarantees the best filtration using BRITA filters. The 4-stage filtration technology, including activated carbon and ion-exchanger pearls, enhances water taste and reduces impurities such as chlorine, limescale, and heavy metals, making it beneficial for those with older pipework.

The product is environmentally friendly, helping reduce plastic waste and has been supporting cartridge recycling since 1995. Packaged in sustainable smart box packaging, it offers easy opening and reduced packaging waste. It stands out in terms of capacity and filtration efficiency, though it requires regular filter replacements and careful handling of the digital indicator. Its lack of electrical components means it’s easy to use without the need for a power source, but it may not suit those looking for a more automated system. With strong customer reviews and a top rank in the water filter jug category, this product reflects German quality design and a reliable brand reputation.

The BRITA Flow XXL Water Filter Tank is designed for families or office use, offering a large 8.2-liter capacity that fits conveniently on fridge shelves or countertops. Its standout feature is the MAXTRA PRO 4-stage filtration system, which uses activated carbon and ion-exchanger pearls to reduce impurities like chlorine, pesticides, heavy metals, and even certain pharmaceuticals. This helps improve water taste, protect appliances from limescale, and support better flavor in drinks like coffee and tea.

The filter also captures microparticles more effectively than previous versions, making it a good choice for older water pipes. One cartridge filters up to 150 liters and lasts about four weeks, with a handy digital reminder to notify you when it's time to change it. Maintenance is simple since the tank is BPA-free and dishwasher-safe, except for the digital indicator. The system is non-electric and freestanding, so it requires no installation or power source. Environmentally, it reduces plastic waste by cutting down on bottled water use, and BRITA has supported cartridge recycling for years.

The system is designed for tap or similar water sources with TDS levels up to 1000 ppm, so it is not suited for very heavily contaminated water.

Its certification and strong customer ratings (4.6/5) provide confidence in its performance and safety. This water purifier is a reliable choice if you want convenient, high-capacity filtered water that fits in your fridge, with low maintenance and effective impurity reduction—ideal for everyday home or office use.
