10 Best Tap Water Filter 2025 in the UK

The BRITA Marella Water Filter Jug Graphite (2.4L) is a versatile and user-friendly water filter jug that fits well in standard fridge doors. It comes with three MAXTRA PRO All-in-1 cartridges, each providing 150 liters of filtered water over approximately four weeks. This jug features an easy-fill flip-lid and a digital Lifetime Indicator that reminds you when to change the filter.

The filtration system, using natural activated carbon and ion-exchanger pearls, effectively removes contaminants such as herbicides, pesticides, chlorine, limescale, lead, and copper, enhancing the taste and quality of your water. The spout cover also keeps impurities like dust out of the filtered water. One of its significant advantages is its BPA-free construction and dishwasher-safe design, except for the digital indicator.

The jug is eco-friendly, reducing the need for plastic bottles and boasting a lower carbon footprint. Its compact size makes it a practical addition to any kitchen. However, the digital indicator may require extra care as it is not dishwasher-safe, and the jug's 2.4-liter capacity may not be sufficient for larger households. This product is ideal for individuals or small families looking for a convenient and effective way to improve their tap water's taste and quality while being environmentally conscious.

The Waterdrop 10UA Under Sink Water Filter is an efficient and compact water filtration system, ideal for households and small commercial applications. With a high capacity of 30,000 liters and a service life of up to 12 months, it ensures long-term usage before needing a filter replacement. The innovative multistage filtration method effectively reduces chlorine, lead, PFAS, PFOA/PFOS, and other contaminants, significantly improving water quality and taste. It is also NSF/ANSI 42 and 372 certified, assuring users of its safety and effectiveness in contaminant removal.

Installation is user-friendly, thanks to the push-to-connect fittings and twist-and-lock design, which make it possible to set up or replace the filter in just a few minutes. The device does not require any electricity, and its compact size and weight (approximately 1.31 kg) make it suitable for various settings, including rented apartments. However, it should only be connected to a cold water supply, and its effectiveness in areas with very hard water might be limited; for such conditions, the manufacturer suggests considering their RO systems.

The flow rate is a robust 3 liters per minute at 60 psi, ensuring a steady supply of filtered water. While this product performs well in contaminant removal, it may not significantly reduce water hardness or total dissolved solids (TDS). If you're looking for an easy-to-install, reliable under-sink water filter that enhances the taste and safety of your tap water, the Waterdrop 10UA is a solid option.

The BRITA Flow XXL Water Filter Tank offers an impressive solution for families and offices looking to improve their tap water quality. It provides a substantial 8.2-liter capacity, making it suitable for larger groups or frequent use. The filtration system relies on the MAXTRA PRO 4-stage process, which effectively targets impurities like chlorine and metals, and reduces limescale, offering clearer and better-tasting water.

One standout feature is the digital lifetime indicator which helps users know when to replace the filter, ensuring consistent water quality. With each MAXTRA PRO cartridge lasting about 150 liters or four weeks, the tank is relatively low maintenance, though frequent replacements could be seen as inconvenient by some users. Installation and use are straightforward as it is a freestanding unit that fits easily on fridge shelves or countertops. Its design includes a convenient tap and sliding lid, emphasizing ease of refilling and cleaning. However, the digital indicator is not dishwasher-safe, which could be a minor drawback for users who prefer fully dishwasher-safe components.

Environmentally conscious users might appreciate that the filter helps reduce plastic waste by eliminating the need for bottled water, and BRITA has been recycling cartridges since 1997. The sustainable packaging and reduced carbon footprint add to its eco-friendly credentials. This water filter tank is a robust option for those needing a large and reliable water filtration system with the added benefit of sustainability. It’s especially beneficial for households or workplaces looking for a convenient and environmentally friendly water solution.
