Best Brita Filter Jugs UK 2026 — vs ZeroWater & Clearly Filtered
Filter jugs are the UK's go-to for quick, chemical-free water upgrades without plumbing work. Brita dominates 60% of the filter-jug market in Britain, but ZeroWater and Clearly Filtered have carved strong niches for people wanting measurably lower TDS (total dissolved solids) or targeting specific contaminants. This guide compares the three brands honestly: Brita's speed and convenience, ZeroWater's ultra-pure output, and Clearly Filtered's activated-coconut-shell approach. We've researched filter life, taste, jug durability, and cost-per-litre across UK tap-water conditions. Most UK homes have moderately hard water (150-200 ppm), so filter choice depends on whether you prioritize convenience (Brita), absolute clarity (ZeroWater), or balanced filtering (Clearly Filtered). Prices range £15–40, with replacement filters adding £2–6 per month. We'll show you which jug wins for taste, which fits tight kitchen spaces, and which offers the best cost-per-litre over 12 months.
What to Look For
- 1Check your water hardness first — UK hardness ranges from 50 ppm (soft, Scotland/Wales) to 400+ ppm (very hard, south-east England). Harder water = shorter filter life. Brita Elemaris includes a hardness tester; ZeroWater does not. If you're in London, Liverpool, or south-east England (hard water), factor in 3–4 filter changes yearly instead of the advertised 200 litres per filter.
- 2Filter cost-per-litre matters more than jug price — Brita Marella (£25 jug + £12/year filters = £37/year). ZeroWater (£35 jug + £80/year filters = £115/year). Clearly Filtered (£30 jug + £45/year filters = £75/year). Over 3 years, Brita costs 56% less. Only switch brands if you taste a measurable difference worth the extra £2–3 monthly spend.
- 3Measure your fridge shelf before buying — Brita Marella and Elemaris are 27cm tall (fit most UK fridges). Clearly Filtered's pitcher is 29cm (may not fit standard shelves). ZeroWater's 3.7L jug is 32cm tall and won't fit side-by-side with milk. Budget space = measure twice, buy once.
- 4Replacement filters are harder to find for some brands — Brita filters are in every supermarket and Amazon Prime same-day (UK). Clearly Filtered ships from the US (2-week lead time). ZeroWater filters are less common but available online within 3 days. If you travel or want same-day refills, Brita wins. Otherwise, buy 2–3 months' filters in bulk.
- 5Taste & smell are the real test — All three remove chlorine equally well. ZeroWater removes more minerals (purer taste, some find it flat). Clearly Filtered removes chlorine + some contaminants (middle ground). Brita removes chlorine + sediment (most UK people prefer the taste). Taste is personal; buy the one with the easiest return policy and test it for 2 weeks.
Our Top Picks
Brita Marella
Pros
- Cheapest filter-jug in the UK (under £25 online)
- Filters widely available (Tesco, Asda, Sainsbury's, Amazon)
- Filter replacement cost lowest of the three (£3 per filter, 4-pack £10)
- Proven 70+ year brand, trusted in UK homes
- Indicator light tells you exactly when filter is spent
- Works well with UK's moderately hard water
Cons
- Filter life is overstated on hard-water days (expect 3–5 weeks vs claimed 200L)
- Plastic jug can stain if left with old water overnight
- Not as 'pure' as ZeroWater (leaves ~80 ppm TDS vs ZeroWater's 0–50)
- Cartridge shape makes it hard to wash inside jug thoroughly
Best for everyday UK homes. Wins on cost, convenience, and taste. Only upgrade if you taste chlorine after 3 weeks (sign you need harder filters) or if you're in a very hard-water area.
ZeroWater ZP-010
Pros
- Removes virtually all dissolved solids (TDS 0–10 ppm) — measurably purer than Brita
- 5-stage filtration removes more contaminants (fluoride, nitrates, heavy metals)
- Electronic TDS meter lets you verify water quality in real time
- Good for people with sensitive taste buds or chlorine sensitivity
- Longer-term water quality if you care about mineral removal
Cons
- Filter life is the shortest of the three (20L in hard-water areas = 2–3 weeks)
- Replacement filters cost £5–6 each (ZeroWater sells in bulk: ~£80/year for UK hard-water users)
- Slowest fill time (5–8 mins vs Brita's 3–4)
- Filters mostly mail-order in UK (not in supermarkets)
- Some users find 0 TDS water tastes flat or unnatural (minerals removed entirely)
- Jug shape taller (32cm) — may not fit all fridge shelves
Best for perfectionists & chlorine-sensitive users. If you taste chlorine in Brita after week 1, ZeroWater is the cure. Cost-per-litre is highest, but water quality is the best. Overkill for most UK homes.
Clearly Filtered 10-Cup
Pros
- Glass pitcher doesn't stain like plastic (stays clearer longer)
- Balanced filtration (removes chlorine + some contaminants, keeps beneficial minerals)
- Mid-range cost (£30–35 jug, ~£45/year filters)
- Filter cartridge fully dissolvable (zero plastic waste per filter)
- Good for people who want purity without the flat taste of ZeroWater
Cons
- Smallest capacity (2.4L vs 3.5–3.7L competitors) — need to refill more often
- Filters only available online (2-week lead time from US)
- Glass pitcher is heavier and can break if dropped
- Not as widely trusted in UK (newer brand, fewer long-term reviews)
- Filter cost per litre slightly higher than Brita, lower than ZeroWater
- Pitcher tall (29cm) — tight fit on some fridges
Best for people who want good filtration + no plastic waste + glass aesthetic. Slower refill times and longer filter lead times make it less convenient than Brita. Good middle ground if you dislike ZeroWater's flatness but want more purity than Brita.
Editor's Note
UK water hardness is the secret variable most people miss. London, Liverpool, and south-east England (hard water zones) will see Brita filters clog every 3 weeks instead of 6. ZeroWater's shorter lifespan is intentional (frequent filter changes = consistent ultra-pure output). Clearly Filtered's coconut-shell stage is good for odour removal but adds cost. None of these jugs remove fluoride except ZeroWater. If you're in a naturally soft area (Scotland, Wales), any of the three will feel luxurious. Start with Brita, taste it for 2 weeks, then decide if the extra cost of ZeroWater or Clearly Filtered is worth it.
