Best water filter jugs for UK homes (2026)

A filter jug is the cheapest way to make hard, chlorinated UK tap water taste better — and in hard-water areas, to cut the limescale that furs up your kettle.

Our verdict
Researched

A dependable, fridge-door-friendly jug that softens the taste of hard tap water and cuts chlorine and limescale. It is an everyday convenience, not an emergency purifier.

Worth knowing: Ongoing cartridge cost adds up: each MAXTRA PRO lasts roughly 150L or about a month

Who shouldn't buy it: Do not buy this as emergency water purification. It improves the taste and hardness of water that is already safe from the mains, and will not make floodwater, rainwater or microbiologically unsafe water safe to drink. For that you need a dedicated purifier, purification tablets or boiling.

Our verdict
Researched

A well-made British jug filter that swaps disposable cartridges for a refillable one, cutting plastic and running costs. It improves the taste of mains water and is certified for chlorine and some metals, but it is a convenience filter, not an emergency purifier.

Worth knowing: The 2.2L glass jug is bulky and can be awkward to fit in smaller fridge doors

Who shouldn't buy it: Don't buy this expecting to make unsafe or non-mains water drinkable in an emergency. A gravity jug filter reduces taste, chlorine and some metals from treated tap water; it does not remove bacteria, viruses or parasites, so for questionable water you need a dedicated purifier or to boil it.

Our verdict
Researched

A well-made, widely stocked jug that improves the taste of UK tap water and cuts limescale, with a generous 3.6L body for a busy household. Treat it as an everyday convenience, not an emergency water-safety device.

Worth knowing: Ongoing cartridge cost adds up (~monthly replacements at ~150L each)

Who shouldn't buy it: Do not buy this for emergency or off-grid water safety: a Brita jug is designed for already-safe mains water and does not remove bacteria, viruses or protozoa. For untreated or contaminated water you need purification tablets, a boil, or a certified microbiological filter instead.

TAPP's current tap filter screws onto most standard kitchen taps and runs water through six stages, the last adding minerals back from Swedish mineral rock. The annual pack comes with four refill cartridges. It's a comfort-and-quality upgrade for everyday drinking water, not an emergency purifier: it needs mains pressure and doesn't disinfect.

Worth knowing: Won't suit pull-out or unusual taps outside the 16 to 24 mm range

Who shouldn't buy it: Don't buy this for emergency preparedness: it needs pressurised mains water and doesn't disinfect against bacteria or viruses, so it's no use when the supply is cut or under a boil notice. Choose a filter straw, gravity filter or purification tablets for that.

Improving the taste of already-safe mains tap water and cutting limescale, on a modest budget.

Our verdict
Researched

A sensible, low-cost jug that noticeably softens the taste of chlorinated hard-water areas, with independently certified filtration. It is a kitchen convenience for everyday mains water, not an emergency purifier.

Worth knowing: Only about 1.2L of the 2.5L total is filtered water, so it needs frequent refilling for a household

Who shouldn't buy it: You are buying it as emergency water treatment. A jug filter improves the taste of water that is already safe; it does not remove bacteria, viruses or parasites and will not make flood, stream or otherwise contaminated water safe to drink. For that you need boiling, purification tablets or a certified microbiological filter.

Households in hard-water areas who want the best-tasting, lowest-TDS filtered mains water and don't mind changing filters often.

Our verdict
Researched

ZeroWater filters mains tap water to 000 TDS, removing more dissolved solids than a standard carbon jug and coming with a meter so you can see it working. It is genuinely effective at improving taste and reducing heavy metals, but the short filter life makes it dear to run, and it is not an emergency purifier.

Worth knowing: Filter life is short and drops sharply in hard-water areas, so running costs are noticeably higher than a Brita.

Who shouldn't buy it: Don't buy this expecting an emergency water purifier: it improves taste and cuts dissolved contaminants in mains water, but it does not disinfect against bacteria or viruses, so it is no substitute for boiling or purification tablets if the mains supply is compromised.

The honest bit
If your tap water is safe (it is, from the UK mains) and you just don't love the taste, the cheapest fix is often a jug you already own plus chilling the water — cold water tastes better. Buy a certified jug if you're in a hard-water area or want to reduce a specific contaminant like lead; skip the premium models if it's only about taste.

Before you buy

Be clear what a filter jug is for

Improving the taste and reducing the limescale and chlorine of water that's already safe from the mains. None of these purify water — they won't make floodwater, rainwater or a contaminated supply safe, which needs boiling, tablets or a dedicated purifier.

The spec that separates them is certification.

A cheap carbon jug improves taste; the ones worth paying more for carry independent NSF/ANSI (or EN 17093) certification for specific contaminants — lead, PFAS 'forever chemicals', heavy metals. ZeroWater filters to zero dissolved solids and includes a meter; Brita and Aqua Optima focus on taste and limescale. Match the claim to what your water actually needs.

Then do the sums on running cost, because that's where jugs get expensive.

A cartridge lasting 100–150 litres is roughly a month for a household — and the cartridges, not the jug, are the real annual cost. Refillable systems (Phox) and long-life tap filters (TAPP) cut both plastic and cost if you'll stick with them.

How we choose

We verify every product's specifications against at least two independent sources, re-check its UK price and stock on a schedule where we can track it automatically, and cross-check safety-relevant claims against official guidance. Every review is labelled Researched or Used and reviewed by us: where we've bought a product, or been sent it free, and used it ourselves, its review says which; where we haven't, our verdict is a considered spec-and-evidence comparison, not a hands-on test. When two products are close, commission can decide which one we pick. A clearly better product always wins. Read our full methodology →

Common questions

What does a water filter jug actually remove?

Most reduce chlorine taste, limescale and some metals; better-certified ones (e.g. ZeroWater) also cut lead, PFAS and other dissolved solids. None remove bacteria, viruses or parasites — they're for improving safe mains water, not purifying.

Do filter jugs remove limescale?

They reduce it — carbon/ion-exchange cartridges soften the water and cut scale, which is why they're popular in hard-water areas. They don't eliminate it entirely, and cartridge life is shorter in hard water.

ZeroWater or Brita — which is better?

ZeroWater filters more thoroughly (to zero TDS, with lead/PFAS certification and a meter) but the cartridges are dearer and shorter-lived. Brita is cheaper to run and fine if you mainly want better taste. Pick by whether you're chasing contaminant removal or just taste.

Can I use a filter jug for emergency or rainwater?

No. A jug won't make floodwater, rainwater or a compromised supply safe — it doesn't disinfect. For that you need to boil the water, use purification tablets, or use a certified microbiological filter.

How often should I change the cartridge?

Typically every 100–150 litres, or about a month for a household — sooner in hard water. Most jugs have an indicator. An overdue cartridge stops working and can worsen taste.

Are water filter jugs worth it?

For taste and limescale in hard-water areas, yes — cheaply. If your water already tastes fine, chilling tap water achieves most of it for free. Buy a certified model only if you want to reduce a specific contaminant.
