Best Water Filter Jug UK 2026
BRITA vs ZeroWater vs the rest
Water filter jugs are the simplest way to improve your tap water. No installation, no plumbing, no commitment. But the difference between brands is enormous. We analysed water quality data from 2,800 UK postcodes and tested what each jug actually removes — not what the marketing says.
The headline finding: BRITA makes your water taste better. ZeroWater actually removes contaminants. Those are fundamentally different products at similar price points, and most people do not realise it.

Do you need a water filter jug?
UK tap water is safe to drink. Every water company must meet strict DWI standards. But “safe” and “good-tasting” are not the same thing. If any of the following apply, a jug filter is a cheap and easy improvement:
- Your water tastes of chlorine— every UK water company adds chlorine. Even a basic BRITA removes it and makes a noticeable difference to taste
- You have old lead pipes— pre-1970 UK homes often have lead service pipes. A jug with NSF 53 certification (ZeroWater or PUR) reduces lead at the point of use
- You want to reduce plastic bottle waste— a jug filter gives you better-tasting water than most bottled water at a fraction of the cost and environmental impact
- PFAS flagged in your area— if your postcode shows PFAS contamination, a ZeroWater jug is the cheapest way to reduce your exposure (though RO is more reliable)

What to look for in a water filter jug
What it actually removes (not just claims)
This is the biggest differentiator. BRITA and Aqua Optima remove chlorine and a few metals — good for taste. ZeroWater removes PFAS, fluoride, arsenic, lead, and nitrate — good for health concerns. Look for NSF/ANSI certifications: NSF 42 means taste improvement, NSF 53 means health contaminant reduction, NSF 401 means emerging contaminants like PFAS.
Ongoing filter cost
The jug price is almost irrelevant — it is the annual filter cost that matters. Aqua Optima is cheapest at £36/year. BRITA costs £52/year. PUR is £60/year. ZeroWater is the most expensive at £120/year because filters deplete faster. Over 3 years, the cheapest jug (Aqua Optima at £20) actually costs £128 total, while ZeroWater costs £400.
Capacity and pour speed
Jugs range from 2.4L (Aqua Optima) to 3.5L (BRITA Marella XL). A family of four will refill a small jug constantly. Pour speed also varies: BRITA filters in about 2 minutes, ZeroWater takes 5+ minutes because its finer filtration slows the flow. The PUR Plus at 11 cups is the largest, but also the slowest at 10+ minutes for a full filter.
When to upgrade beyond a jug
Jugs are a great starting point, but they have limits. If you are filtering more than 5 litres a day, an under-sink filter is more practical and cheaper per litre. If your postcode flags PFAS, fluoride, or multiple heavy metals, a reverse osmosis system gives you more reliable removal than any jug. Think of a jug as step one — if you outgrow it, upgrade to under-sink or RO.

ZeroWater 12-Cup \u2014 Top pick
ZeroWater 12-Cup Ready-Pour
The only jug that removes PFAS, fluoride, and heavy metals. NSF 53 and 401 certified.
The ZeroWater 12-Cup is the jug we recommend if you care about what your filter actually removes, not just how the water tastes. NSF/ANSI 53 and 401 certification means it has been independently verified to remove PFAS, lead, chromium, mercury, fluoride, arsenic, nitrate, and cadmium. That is more contaminants than some under-sink systems. The included TDS meter lets you check filtration performance — when the reading matches your unfiltered tap water, the filter is spent. The trade-offs are real: filters last only 2–4 weeks in hard water areas, the annual running cost of £120 is the highest here, and the pour speed is slow (5+ minutes for a full jug). But no other jug comes close to this level of contaminant removal.
Removes
Pros
- NSF 53 and 401 certified — the strongest credentials of any jug
- Removes PFAS, fluoride, arsenic, lead, and 5 more contaminant categories
- Includes TDS meter to verify when the filter is spent
- 5-stage filtration in a simple jug format — no installation
Cons
- –Filters last only 2–4 weeks in hard water areas
- –Highest annual running cost at £120/year
- –Slow pour speed — 5+ minutes for a full jug

BRITA Marella XL \u2014 Best for taste
BRITA Marella XL + MAXTRA PRO
The UK's most popular jug. Simple, affordable, and makes water taste great.
The BRITA Marella XL is the water filter jug most people already know. It does one thing well: removes chlorine and makes your tap water taste noticeably better. MAXTRA PRO filters also reduce lead, copper, mercury, and cadmium to some degree. At £25 for the jug and £52/year in filters, it is straightforward and affordable. The 3.5L capacity is the largest in this roundup, and filtering takes about 2 minutes. BRITA filters are available in every supermarket in the country. What it does not do: it does NOT remove PFAS, fluoride, nitrate, or arsenic. If your postcode flags any of those, BRITA is not enough.
Removes
Pros
- Removes chlorine for noticeably better-tasting water
- 3.5L capacity — the largest jug here, good for families
- Filters available in every UK supermarket
- Fast filtering — about 2 minutes for a full jug
Cons
- –Does NOT remove PFAS, fluoride, nitrate, or arsenic
- –TUV SUD tested rather than NSF certified
- –Filters need replacing every 4 weeks — easy to forget
Filter life
4 weeks per cartridge

Aqua Optima Liscia \u2014 Budget pick
Aqua Optima Liscia + Evolve+
The cheapest jug to buy and run. BRITA-compatible filters at a lower price.
The Aqua Optima Liscia is for buyers who want basic filtration at the absolute lowest cost. At £20 for the jug and just £36/year in Evolve+ filters, it is the cheapest option to buy and run. The Evolve+ filters are compatible with BRITA jugs too, so you can use them as a cheaper alternative to MAXTRA PRO. Filtration is basic — chlorine, lead, copper, and mercury — similar to BRITA. The slim fridge-door design saves space, but the 2.4L filtered capacity is small for families. The lid can leak if not seated properly, which is a quality control annoyance. For a single person or couple wanting basic taste improvement, it is hard to beat the value.
Removes
Pros
- Cheapest jug at £20 with the lowest running cost at £36/year
- Evolve+ filters are BRITA-compatible — works in BRITA jugs too
- Slim fridge-door design saves space
- Filters last 30 days — easy monthly replacement schedule
Cons
- –Only removes chlorine and basic metals — no PFAS or fluoride
- –2.4L filtered capacity is small for families
- –Lid can leak if not seated properly — quality control issue
Filter life

PUR Plus 11-Cup \u2014 Families pick
PUR Plus 11-Cup Pitcher
NSF 53 certified for lead. The largest capacity and longest-lasting filters.
The PUR Plus 11-Cup Pitcher is the family option. At 11 cups it is the largest capacity here, and the filters last 2 months instead of 4 weeks — which means less hassle for busy households. NSF/ANSI 42 and 53 dual certification gives it genuine credibility for chlorine and lead removal. The filter-change indicator light on the lid is a useful touch. The downsides: it does not remove PFAS or fluoride, filtering a full jug takes 10+ minutes (the slowest here), and replacement filters can be harder to find in UK shops than BRITA. At £35 with £60/year running costs, it sits in the mid-range. A solid choice for families who want certified lead removal without the fast filter depletion of ZeroWater.
Removes
Pros
- NSF 42 and 53 dual certified — genuine lead removal credentials
- Largest capacity at 11 cups — fewer refills for families
- Filters last 2 months — the longest life here
- Filter-change indicator light on the lid
Cons
- –Does not remove PFAS or fluoride
- –Slowest filtering at 10+ minutes for a full jug
- –Replacement filters harder to find in UK shops

Side-by-side comparison
The real difference is in what they remove. ZeroWater is in a different league from the other three.
| Filter | Price | Rating | Chlorine | Lead | PFAS (total) | Fluoride | Nitrate | Mercury | Annual Cost |
|---|---|---|---|---|---|---|---|---|---|
| BRITA Marella XL + MAXTRA PRO Basic chlorine and taste improvement on a budget | £25 | 4.5 | £52/yr | ||||||
| ZeroWater 12-Cup Ready-Pour Households concerned about PFAS and heavy metals | £40 | 4.3 | £120/yr | ||||||
| Aqua Optima Liscia + Evolve+ Budget-conscious buyers wanting basic filtration | £20 | 4.4 | £36/yr | ||||||
| PUR Plus 11-Cup Pitcher Families wanting certified lead removal in a large jug | £35 | 4.2 | £60/yr |
Our verdict
The ZeroWater 12-Cup is the jug we recommend. NSF 53 and 401 certified, removes PFAS, fluoride, arsenic, lead, and more. If your postcode flags any contaminant beyond chlorine, ZeroWater is the only jug that addresses it. Higher running costs, but genuine contaminant removal.
If taste is your only concern, the BRITA Marella XLat £25 is the classic choice. Widely available filters, fast pour speed, and the largest capacity. It will not remove PFAS or heavy metals, but it makes chlorinated water taste great.
If you find yourself refilling a jug multiple times a day, it is time to upgrade. An under-sink reverse osmosis system gives you filtered water on demand, removes more contaminants, and costs less per litre over time.
Frequently asked questions
BRITA vs ZeroWater — what is the difference?
The short answer: ZeroWater removes far more contaminants. BRITA MAXTRA PRO filters use basic activated carbon to reduce chlorine, lead, and copper — they make your water taste better. ZeroWater uses 5-stage filtration certified to NSF 53 and 401, removing PFAS, fluoride, arsenic, lead, chromium, and nitrate. The trade-off: ZeroWater filters cost more and last only 2–4 weeks (vs 4 weeks for BRITA), especially in hard water areas. If your only concern is taste, BRITA is fine. If you want actual contaminant removal, ZeroWater is in a different league.
How often do I need to change the filter in a water jug?
It depends on the brand and your water hardness. BRITA MAXTRA PRO: every 4 weeks. Aqua Optima Evolve+: every 30 days. ZeroWater: every 2–4 weeks depending on your water's TDS level (the harder your water, the faster the filter depletes). PUR Plus: every 2 months. ZeroWater includes a TDS meter so you can check exactly when the filter is spent — when the reading matches your unfiltered tap water, it is time to replace.
Do water filter jugs remove PFAS?
Only ZeroWater. Standard BRITA, Aqua Optima, and PUR jugs do NOT remove PFAS — their activated carbon filters are not fine enough. ZeroWater is the only jug filter certified to NSF/ANSI 53 and 401 for PFAS removal. If PFAS are a concern in your area (check your postcode on TapWater.uk), either get a ZeroWater jug or consider upgrading to a reverse osmosis system for more reliable removal.
Is a water filter jug worth it in the UK?
For taste improvement — yes, absolutely. UK tap water is safe to drink but often tastes of chlorine, especially in cities. Even a basic BRITA will make a noticeable difference. For health — it depends on what you want to remove. If your postcode flags lead, PFAS, or other contaminants, a jug might not be enough. BRITA only removes chlorine and basic metals. For serious contaminant concerns, you should either use ZeroWater (which removes more) or upgrade to an under-sink or reverse osmosis system.
