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. Here's how the main jugs compare on what actually matters: taste, what they're independently certified to remove, and the running cost of the cartridges.

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.
Top pick: Brita Marella Water Filter Jug 2.4L. 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.

Brita Marella Water Filter Jug 2.4L
Who it's for: Everyday better-tasting tap water and limescale reduction in hard-water areas
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.
- Widely stocked and inexpensive, with replacement cartridges available almost anywhere in the UK
- Cuts chlorine taste, limescale and metals like lead and copper for pleasant everyday drinking water
- Fridge-door design with a clear digital indicator that flags when the cartridge is due for changing
- Ongoing cartridge cost adds up: each MAXTRA PRO lasts roughly 150L or about a month
- Only around 1.4L of the 2.4L total is filtered water, so it needs frequent topping up
Don't buy if 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.
Phox V2 Water Filter Jug
Who it's for: Households wanting better-tasting tap water with far less plastic waste.
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.
- Refillable cartridge design cuts plastic waste and keeps refills cheaper than most rival pods
- Certified to EN 17093 for chlorine, lead, copper and nickel reduction, with a sturdy glass jug
- Well regarded in the UK, with strong retailer reviews and a Telegraph Best Buy nod
- The 2.2L glass jug is bulky and can be awkward to fit in smaller fridge doors
- Cartridge lasts only about 45 days or 200 litres, so it needs regular refilling to stay effective
Don't buy if 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.
TAPP Water EcoPro Tap Water Filter
Who it's for: Everyday better-tasting mains water and less limescale, without the plastic of a jug.
A neat, low-fuss filter that screws onto a standard tap and noticeably improves taste while cutting chlorine and limescale. Sensible value for daily household use, though it is a comfort-and-quality upgrade rather than an emergency purifier.
- Screws onto most standard round taps in minutes with no plumbing or tools
- Cartridge lasts roughly three months or about 1,200 litres, so running cost is low versus jug filters
- Reduces chlorine, limescale, microplastics and many other substances while keeping useful minerals
- Not NSF-certified as a complete unit (the filtration media is independently lab-tested rather than the whole product certified)
- Fits standard round taps only, so pull-out, square or spray-style taps may need an adapter or won't fit
Don't buy if Don't buy this for emergency preparedness: it needs pressurised mains water to work and does not disinfect against bacteria or viruses, so it is no use in a loss-of-supply or boil-notice situation. For that, choose a dedicated purifier (filter straw, gravity filter or purification tablets) instead.
Aqua Optima Evolve+ Water Filter Jug
Who it's for: Improving the taste of already-safe mains tap water and cutting limescale, on a modest budget.
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.
- Inexpensive to buy and the filters are WQA-certified to recognised NSF/ANSI standards for chlorine, limescale and some heavy metals
- Uses the widely-stocked multi-fit Evolve+ cartridge, which also fits most Brita jugs, so replacements are easy to source
- Dishwasher-safe, BPA-free and slim enough for a fridge door
- Only about 1.2L of the 2.5L total is filtered water, so it needs frequent refilling for a household
- The 30-day (100L) filter life means an ongoing cartridge cost that adds up over a year
Don't buy if 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.
ZeroWater 12 Cup Water Filter Jug
Who it's for: Households in hard-water areas who want the best-tasting, lowest-TDS filtered mains water and don't mind changing filters often.
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.
- Filters to 000 total dissolved solids, reducing lead, chromium, fluoride and PFOA/PFOS more thoroughly than typical carbon jugs; a TDS meter is included so you can check performance.
- IAPMO-tested against NSF/ANSI 42 and 53 for heavy-metal and PFAS reduction, which is stronger third-party backing than many rivals.
- Practical 2.8L design with a sealed reservoir and one-handed pour spout that sits neatly in the fridge door.
- Filter life is short and drops sharply in hard-water areas, so running costs are noticeably higher than a Brita.
- Flow is slow and the water can develop a sour, lemony taste once the cartridge is spent.
Don't buy if 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.
Brita Style XL Water Filter Jug 3.6L
Who it's for: Everyday better-tasting tap water and limescale reduction in a hard-water home.
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.
- Large 3.6L capacity suits families and reduces refills
- Genuinely improves taste and reduces limescale, chlorine and some metals from mains water
- Cartridges (MAXTRA PRO) are cheap and sold everywhere, so ongoing running costs are predictable
- Ongoing cartridge cost adds up (~monthly replacements at ~150L each)
- Bulky footprint that may not fit smaller fridge shelves
Don't buy if 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.

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.
