A gravity water filter is the simplest way to improve tap water at home: pour water into the top, let gravity pull it through the filter media, and draw clean water from the bottom. No plumbing, no electricity and no installer. That simplicity is why demand keeps growing in the UK, helped along by headlines about PFAS “forever chemicals”, microplastics, boil water notices and the steady cost of bottled water.
The UK market splits into two broad camps. At one end are stainless steel countertop systems holding six to twenty litres, which use carbon, ceramic or membrane elements and are built to sit on the worktop for a decade. At the other are filter jugs, which are gravity filters too, just smaller and cheaper, and mostly aimed at taste, chlorine and limescale. Picking the best gravity water filter UK households can buy comes down to how much water you drink, what is in your supply and how much you want to spend on cartridges over the years.
We looked at each brand’s own UK website or authorised UK seller to confirm what it sells, what the filters are tested against and what the running costs look like. Where a performance figure comes from the brand rather than an independent certification, we say so.

Best Gravity Water Filters In The UK In 2027
1. Weeplow: Stainless Steel Gravity Systems With 22,000-Litre Filters
Weeplow is a French brand of stainless steel gravity water filters and our top pick for UK households that want to replace bottled water with a countertop system rather than a jug. Each unit is a mirror-polished, food-grade AISI 304 steel urn that filters tap water without power or plumbing, in three sizes matched to the household: the Venus 5.6L for one or two people, the Earth 8.5L for three to five, and the Neptune 11L for five or more. The Venus and Earth also come as Essential Editions, without the base and water level gauge, for smaller worktops.
What sets Weeplow apart from most steel systems is the filter. Each O’Pure 2 element combines coconut-shell activated carbon fibre for taste and chemicals with a 0.02 micron hollow-fibre ultrafiltration membrane, which, according to the brand, also removes microplastics mechanically. Weeplow reports nearly 99.99% E. coli reduction in tests by independent US laboratories, more than 99.9% PFAS reduction, and 99.9999% MS2 virus reduction in independent SGS testing under controlled conditions, plus reductions above 98% for lead, mercury, copper, cadmium, iron, manganese and zinc in tests against NSF/ANSI 42 and 53 protocols. Those are tests against the standards rather than NSF certification, and Weeplow publishes the reports on its product pages so buyers can check them.
Running costs are low for a steel system. Weeplow rates each pair of elements at up to 22,000 litres, one to two years for most homes, and a replacement pair is £109.99, under a penny per litre at rated capacity. With two elements fitted, Weeplow quotes a flow rate of up to 3.8 litres an hour. Households that also want fluoride or arsenic reduction can add the O’Pure 2B, which screws onto the main elements; Weeplow says it reduces both by more than 99% over roughly 3,785 litres.
One point for hard-water areas: Weeplow keeps natural minerals in the water by design, so it will not soften water or reduce limescale. Setup is tool-free in about 20 minutes, chambers and fittings carry a 10-year warranty, UK orders ship with 48-hour delivery and support runs seven days a week. Weeplow says more than 100,000 customers use its filters, with an average rating of 4.74 out of 5. At the time of writing, the Venus is £209.99, the Earth £229.99 and the Neptune £259.99, with Essential Editions from £169.99 and regular discount codes.
2. British Berkefeld: Made In Britain With NSF-Certified Ceramic Candles
British Berkefeld is the heritage choice. It is made by Doulton, which has been producing filters in Staffordshire since 1826, and its stainless steel gravity systems are made in Britain. The range covers 1, 6, 8.5 and 12 litre housings, with filtered capacities of 1, 5.6, 7.8 and 11.5 litres. On Doulton’s UK store, the 6-litre system with two Ultra Sterasyl candles starts at around £124.95, the 8.5-litre bundle is about £255.85, and the 6-litre system with Ultra Fluoride candles starts from £205.95.
The Ultra Sterasyl candle is the reason many buyers choose British Berkefeld. Doulton states that it is tested and certified by NSF to NSF/ANSI 401, and it targets PFAS, microplastics, bacteria, cysts and particulates. The Ultra Fluoride candle adds fluoride reduction, which Doulton says it tested in-house at up to 98.9% at a 1 ppm influent concentration, with a stated adsorption capacity of about 1,950 litres at that level.
The trade-offs are maintenance and running costs. Doulton recommends changing candles every six months, with replacement Ultra Sterasyl candles from £23.95 and Ultra Fluoride from £43.95. Ceramic candles also need periodic cleaning to keep water flowing, and independent testers have measured flow rates lower than many carbon-based systems. If certification is your top priority and you do not mind the routine, it remains one of the most credible options in the UK.
3. Berkey: Large-Capacity Systems For Big Households
Berkey offers the widest range of sizes among the steel systems on this list. In the UK it is sold by Berkey Water Filters UK and EU, which describes itself as an authorised seller and distributor for the UK and Europe since 2014. Systems run from the Travel Berkey at 5.7 litres through the 8.5-litre Big Berkey and 12-litre Royal to the Imperial at 17 litres and the Crown at 23 litres, listed between £365 and £460 at the time of writing. Black Berkey elements are £360 a set and PF-2 fluoride filters £125.
Berkey’s recent history is worth knowing. In the US, the Environmental Protection Agency issued stop-sale orders from late 2022 into 2023 over how the silver-containing Black Berkey elements should be classified under federal pesticide law, and Berkey’s maker sued the EPA in August 2023. The dispute disrupted US supply of replacement elements; it was a regulatory classification matter, not a finding about water quality. The UK distributor currently lists systems and elements in stock and warns about counterfeit Berkey filters on online marketplaces, so buy from an authorised channel.
Berkey claims its elements remove 99.9% of harmful chemicals, but the Black Berkey elements do not carry NSF/ANSI performance certification, a point independent reviewers often raise. Buyers who want maximum capacity and are comfortable with brand-reported data still choose Berkey; those who prize certification may lean elsewhere.
4. Phoenix Gravity: Carbon Cartridge Systems With A Yearly Subscription
Phoenix Gravity is sold in the UK by Phoenix Water Filters Ltd of Mitcham, London. The systems are designed and manufactured exclusively by Rama, which the company describes as a British-Indian partnership making gravity filters since 1978. Housings are AISI 304 stainless steel in 6, 8 and 12 litre sizes, aimed at one to two, two to four and four to six people respectively.
The filter is a Smart Carbon Cartridge made from silver-infused CTC 60 coconut-shell activated carbon, rated to last up to 12 months. Phoenix sells replacements on a subscription at £69 a year, which makes the cost of ownership very easy to budget. An optional POSTreat cartridge targets fluoride, with Phoenix claiming more than 95% reduction.
Phoenix displays an NSF/ANSI 42 and 372 badge and says its chlorine reduction is NSF/ANSI 42 certified, with other contaminant figures coming from independent lab reports linked on the site. The system lists at £199, often discounted, and comes with a 10-year warranty, a 100-day money-back guarantee and free UK delivery over £99.
5. Brita: The Familiar Filter Jug And An 8.2-Litre Tank
Brita is the name most UK households already know, and its jugs are gravity filters in their simplest form. The UK range includes the Style Essential jug from £26.99, a glass jug at £59.99 and the Flow, an 8.2-litre filter tank with a tap at £59.99 for anyone who wants more volume without a steel system. Cartridges are stocked at nearly every UK supermarket.
The MAXTRA PRO Pure Performance cartridge, formerly sold as All-in-1, uses MicroCarbon pearls and ion exchange. Brita says it is tested to DIN EN 17093:2018 for lead, copper, chlorine and carbonate hardness, reduces limescale for up to 120 litres, and reduces certain herbicides, pesticides and pharmaceuticals if present. A Limescale Expert cartridge is aimed at very hard water.
Brita is not designed for microbiological reduction, and a plastic jug will not suit buyers trying to cut plastic. For better-tasting tea, less scale in the kettle and a low upfront price, though, it is hard to beat for convenience.
6. Aquaphor: Budget Filter Jugs With Long-Life Cartridges
Aquaphor is a filtration manufacturer with more than 1,000 employees and production plants in Estonia and Israel, and it runs a dedicated UK store. Its jug range is broad and keenly priced: the Smile 2.9L at £12.99, the Amethyst 2.8L at £14.99, the Provence and Onyx 4.2L at £21.99, and a glass 2.5L at £34.99.
The selling point is cartridge life. Aquaphor’s A5 cartridge is rated at 350 litres and the MAXFOR at 200 litres, both well above a typical jug cartridge. Aquaphor says its AQUALEN filtration reduces chlorine, limescale, microplastics and PFAS, and a magnesium-release version of the A5 adds minerals back. The company cites ISO 9001:2015 certification for its quality management.
Aquaphor also sells the J.SHMIDT 500, a 2.8-litre jug rated at 500 litres that it describes as an electric-powered antibacterial filter jug, for buyers who want more than a carbon cartridge in a jug format. For a large-capacity jug on a small budget, Aquaphor offers strong value.
7. BWT: Magnesium-Mineralised Water For Tea And Coffee
BWT, the Austrian water technology group, sells its filter jugs and cartridges to UK buyers through its UK site and the BWT Shop. The jug range includes the Vida, with a 2.6-litre model listed at £15.59 on the BWT Shop, and the Penguin, which works with BWT’s Magnesium Mineralized Water, Magnesium plus Zinc and Balanced Alkalized Water cartridges.
BWT’s angle is taste rather than heavy-duty filtration. Its Magnesium Mineralized Water cartridge adds magnesium while, according to BWT, reducing limescale, chlorine and heavy metals. BWT rates the cartridge at 120 litres in water of 15 to 18 degrees German hardness, less in harder water, and recommends replacing it every four weeks at the latest. Soft Filtered Water cartridges are also available for very hard supplies.
Coffee and tea drinkers are BWT’s natural audience, and the brand is widely used in professional coffee machines for the same reason. A reusable cartridge with refills is also listed on the BWT Shop for buyers who want to reduce waste.
PHOX tackles one of the biggest complaints about filter jugs: the pile of spent plastic cartridges. Its cartridge is refillable and made in the UK, and the company describes it as the world’s first refillable water filter cartridge. You top it up with fresh filter granules every 45 days or 200 litres.
The range is small and focused. The Glass V2 jug holds 2.2 litres and the Wave jug 2.8 litres, both from £39.99, and PHOX also sells a refillable cartridge that fits MAXTRA-style jugs from £14.99, so you can keep your existing jug. Refill packs come in three versions at £14.99 for three months: Clean for moderately hard water, Alkaline, which PHOX says reduces chlorine and heavy metals while adding magnesium and calcium, and Softener for very hard water.
PHOX says its filtration is tested but does not name a lab or standard on its site, so treat performance claims as the brand’s own. For eco-minded buyers who are happy with a jug, it is the lowest-waste option here.
9. Waterdrop: NSF-Certified Jugs And Countertop Dispensers
Waterdrop runs an official UK store with GBP pricing and free UK delivery. Alongside its reverse osmosis systems, it sells a range of gravity jugs and dispensers, including the 5-cup Elfin, 10-cup jugs such as the Chubby, and a 20-cup countertop dispenser for families who want more than a jug.
The Chubby is a good example of the range. It is listed at £61 and Waterdrop says its filter is NSF 42 certified to reduce chlorine, taste and odour, with NSF 372 certification for lead-free materials. Waterdrop reports 97.4% chlorine reduction and rates each filter at up to three months or 757 litres. The brand also sells a 0-TDS jug for buyers who want dissolved solids stripped out entirely.
Waterdrop sits between the cheapest jugs and the steel systems: more certification detail than most jug brands, with dispenser options for bigger households, but still plastic and aimed mainly at taste and chlorine.
10. Ecofiltro: Clay Pot Filtration Without Steel Or Plastic Cartridges
Ecofiltro takes the oldest approach on this list. Founded in Guatemala, where it is B Corp certified, the brand is sold in Europe by Ecofiltro Europe SL, which ships to the UK on a delivered-duty-paid basis so there are no customs charges on arrival, with GBP pricing available at checkout. The filter is a single ceramic pot made from clay, activated carbon and colloidal silver, sitting inside a 5-litre or 20-litre container, and it needs no electricity or plumbing.
Ecofiltro publishes detailed lab figures from named laboratories. It reports 99.9% E. coli reduction with no coliform detected across a 5,000-litre test (LAE, Mexico, 2023), more than 98% glyphosate reduction (LATU, Uruguay, 2025), lead, cadmium and mercury removal, no detected 70 micron microplastic particles after filtration (Measurlabs, 2025) and 13 of 14 tested pharmaceuticals below the quantification limit. It is candid that arsenic reduction is 63% and fluoride 26%, so it is not the right pick if fluoride is your main concern.
The 5-litre model comes in several colours and was listed at €144, though it showed as sold out when we checked, so confirm stock before ordering. For buyers who want a low-tech, low-plastic filter with transparent testing, it is a distinctive alternative to steel urns and jugs.
How To Choose A Gravity Water Filter
What do you actually need to filter out?
Start with your water company’s free water quality report, which you can look up by postcode. If your mains supply is fine and you want better taste and less chlorine, a filter jug is enough. If you are concerned about PFAS, microplastics or lead from older pipes, or you use a private supply, a countertop gravity fed water filter with carbon plus ceramic or membrane media is the better fit.
Jug or countertop system?
Jugs are cheap and fit in the fridge, but most hold under two litres of filtered water and need a new cartridge every month or so. Countertop systems hold five to twenty litres, use longer-life elements and suit families who drink, cook and make hot drinks with filtered water all day. If you refill a jug several times a day, you have outgrown it.
How much will it cost over three years?
Compare cost per litre rather than sticker price. A £15 jug with £5 monthly cartridges can cost more over three years than a steel system with filters rated for tens of thousands of litres. Check each cartridge’s rated capacity, replacement price and change interval, then do the maths for your household.
Is stainless steel worth it?
AISI 304 stainless steel housings are durable, do not stain and often come with ten-year warranties. Plastic jugs and tanks are lighter and cheaper but wear out and add to plastic waste, and glass sits in between. If you plan to keep a countertop water filter for many years, steel usually pays off.
Does it remove limescale?
This is the most common surprise for UK buyers. Ion exchange cartridges in jugs reduce limescale; most carbon, ceramic and ultrafiltration systems do not, because they are designed to keep minerals in the water. If limescale is your main complaint, check this before you buy.
How do you check the claims?
Read the wording. “Certified to NSF/ANSI” means an independent body certified the product. “Tested against” a standard means a lab ran the protocol but the product is not certified. Brand figures with no published report are the weakest evidence, and the best gravity water filter brands make their reports easy to find.
Conclusion
The UK gravity water filter market now covers every kitchen, from £13 jugs to stainless steel systems built to last a decade. Weeplow leads for households that want to stop buying bottled water and move to a steel countertop system with filters rated for up to 22,000 litres and published lab results for bacteria, viruses, PFAS and heavy metals. British Berkefeld remains the certified heritage choice, Berkey and Phoenix Gravity add more steel options and Ecofiltro offers a plastic-free clay alternative, while Brita, Aquaphor, BWT, PHOX and Waterdrop cover every jug budget. Check your water report, work out the cost per litre and read the test results before choosing.
