The best glass water filters, compared.
Top pick: Waterdrop PT-72 white jug Best value: AQUAPHOR white glass jug – Lowest shelf price with a glass jug and one cartridge, about £34.99, with 4.2 from 303 reviews. Updated 22.10.2026.
Filter glass is a drinking-water filter with a glass reservoir. In the UK you buy one because you dislike chlorine taste or kettle scale, or because you do not want drinking water sitting in a plastic jug. Public mains water is already required to be wholesome, so a jug is not a health-protection device. You tell a useful listing from a vague one by the job it states, the standard number matched to that job, the filtered capacity rather than only the total fill, and whether you will change the cartridge on time. NSF/ANSI 42 covers chlorine taste and odour. NSF/ANSI 53 covers the health-effect claims listed for that model only. NSF/ANSI 58 is the reverse-osmosis standard. NSF/ANSI/CAN 372 means lead-free materials, not that the unit removes lead from the water. Daily quality is then hygiene and fit: cold water, a timed cartridge change, and a body that fits the fridge if that is where it will live. The split between a gravity jug and a countertop membrane is in the [filter glass buying guide](/hub/diy-supplies/filter-glass/sub/filter-glass-buying-guide).

Question 1 of 2
What do you want the water to do?
The Waterdrop WD-PT-72W is a borosilicate gravity jug at about £39.99 of 2.5 litres, listed with a two-month filter or up to 100 gallons and a stated flow of 250 ml per minute. The highlight claims NSF/ANSI 42, 53 and 372, and the bullets name PFOA/PFOS, chlorine, cadmium, copper and mercury, while also saying this system does not lower TDS. The star line is 4.6 from 17,655 reviews, the same line, rank and opening texts as the black PT-72, and some of those texts are about another jug, so the count is a shared pool. At 25.5 × 20.5 × 27.5 cm and 1.6 kg, reviews in that shared text say it will not fit a fridge door and belongs on a shelf. The body is borosilicate with a plastic insert and liner, and the origin line says China. It is a plausible counter jug if you want those certificate numbers on the highlight and you will not judge it with a TDS pen. It is a poor pick if you are treating 17,655 as a white-only sample.
Pros
Cons
Best for: You want a glass gravity jug with those NSF numbers on the page, and you will keep it on a shelf rather than in a fridge door.
Less suitable: You need a fridge-door jug, a review count that belongs only to this listing, or a lower TDS reading.
Specifications
Common questions
Does the white PT-72 lower TDS?
The bullets say this system does not lower TDS. They point to a different Waterdrop model if you want a lower TDS.
Why is the review count 17,655?
The same 4.6 from 17,655 line, the same rank, and the same opening reviews are on the black PT-72. Some texts are about another jug. Treat it as a shared pool.
Will it fit a fridge door?
The size is 25.5 × 20.5 × 27.5 cm. UK reviews in that shared text say it will not fit a fridge door. A shelf is the fit they describe.
The Waterdrop WD-PT-72B is the black PT-72 at the same about £39.99, the same 25.5 × 20.5 × 27.5 cm, and the same 4.6 from 17,655 line as the white jug. The printed weight is 1.55 kg against 1.6 kg on the white listing, and the highlight says black. Filtration is described as activated carbon, ion exchange and a carbon block, with the same contaminant names, and the bullets again say it does not lower TDS. The opening reviews match the white listing, including a review of another jug, so this file does not separate black-only faults. The highlight names PFOA/PFOS, chlorine, cadmium, copper and mercury plus NSF/ANSI 53, 42 and 372, and the word lead is not on that highlight line. It is the colour alternative when the white body is unavailable and the certificate line is what you came for. It is not a second, independent 17,655-review verdict.
Pros
Cons
Best for: You want the black PT-72 body and you will treat the 17,655 line as shared with the white listing.
Less suitable: You want lead named on the highlight, or a review set that is only this listing.
Specifications
Common questions
How is the black PT-72 different from the white one in this capture?
The model is WD-PT-72B, the highlight says black, and the weight is 1.55 kg against 1.6 kg. Price, filter life, size and the 17,655 review line match.
Do the reviews describe this black jug?
The opening reviews are the same text as on the white listing, including a review of another jug. The file does not separate black-only faults.
Does the highlight say it removes lead?
It names PFOA/PFOS, chlorine, cadmium, copper and mercury, plus NSF/ANSI 53, 42 and 372. The word lead is not on that highlight line.
The Santevia 9GS-300 is an 8 litre gravity system at about £212.49, with a MINA fluoride filter listed for two months and mineral stones listed for two years. The star line is 4.5 from 213 reviews, and in the first 50 stored texts only a handful are marked United Kingdom, so leaks and a warped filter in that file sit on US or Canada datelines. The bullets claim fluoride, chlorine, lead and PFAS plus added minerals, and they say tested to NSF without printing standard 42, 53 or 58. It is gravity fed, with a glass reservoir and a bamboo stand in the bullets, and the item weight is 8.22 kg, which keeps it on the counter. Dimensions are not in the capture. The supported TDS maximum is 500 ppm, and TDS reduction is not stated. It is a counter system if you specifically want the fluoride bullet and the mineral stones and you treat the 213-review line as mostly outside the UK. It is the wrong spend if you wanted a jug you can lift into a fridge.
Pros
Cons
Best for: You want a large gravity reservoir with a fluoride bullet and mineral stones, and you accept a thin UK review sample.
Less suitable: You need a printed NSF number, a fridge jug, or review evidence that is mostly from the United Kingdom.
Specifications
Common questions
Does the Santevia listing name an NSF standard number?
The bullets say tested to NSF and claim fluoride, chlorine, lead and PFAS reduction. They do not print 42, 53 or 58.
Are the 213 reviews United Kingdom reviews?
The star line is 4.5 from 213. In the first 50 stored texts, only a handful are marked United Kingdom. Leaks and a warped filter in that file are on US or Canada datelines.
Does it need a socket?
The power line says gravity fed. A stored question asks if it needs to be plugged in. The capture does not list a plug.
Across 4,649 amazon.co.uk reviews, the BRITA glass jug (model 1050453) is about £47.49 with three MAXTRA PRO cartridges, the largest review count in this capture that is not printed on a second listing. The bullets describe carbon and ion-exchange pearls and name chlorine, limescale, lead and copper, and the highlight names PFAS, without an NSF standard number on the page. The bullets say 1.5 litres filtered from a 2.5 litre jug, while the specification capacity line says 2.4 litres, so both figures stay in the row. At 13.8 × 19.3 × 27.7 cm and 0.83 kg it is lighter than the PT-72, and the flow line is 10 litres per hour. UK reviews say the lid and inner parts are plastic, and one estimates about 40 percent plastic, which matches a material line that already lists borosilicate glass, a silicone ring and plastic. The cartridge interval is four weeks or 150 litres, shorter than a 60-day line, and the supported TDS maximum is 300 ppm. In this set it is the top pick because the review file belongs to this listing. It is the wrong jug if you need a tight fridge door or a steel refill instead of MAXTRA PRO cartridges.
Pros
Cons
Best for: You want the deepest single-listing review file in this set, with three cartridges in the first box, for taste and some kettle scale.
Less suitable: You need a fridge-door fit, a printed NSF line, or a refillable steel cartridge.
Specifications
Common questions
How much filtered water does the BRITA glass jug hold?
The bullets say a 2.5 litre jug gives 1.5 litres of filtered water. The specification capacity line says 2.4 litres. Both figures are in the capture.
Is the whole jug glass?
The material line lists borosilicate glass plus a silicone ring and plastic. UK reviews say the lid and inner parts are plastic. One review estimates about 40 percent plastic.
Can it go in the dishwasher?
The bullets say dishwasher safe up to 60°C except the Smart Light and the silicone ring. The specification upper temperature is 100°C. Those two lines are both present.
The Waterdrop WD-M6HG is a countertop reverse-osmosis unit at about £429 with a 1.2 litre glass pitcher, a stated Type G plug, and hot water up to 95°C. The highlight claims NSF/ANSI 58 and 372, and the bullets say it reduces TDS and name PFOA, PFOS, nitrate, fluoride, arsenic and lead, then remineralisation. The amazon.co.uk line is 4.3 from 168 reviews, and several of the 50 stored texts describe other Waterdrop models, so the file is mixed. The bullets say you fill a 5.5 litre tank split as 4 litres of feed and 1.5 litres of waste, at 3:1 pure to drain, and UK reviews call emptying that waste a daily chore. At 9.89 kg and 40.3 × 23.5 × 36.9 cm it is a counter machine, with a daily capacity line of 284 litres. Fault notes that name this unit include a dead unit, a leak and hot water below the setpoint on a small pour, and filter life is absent from the specification although one review says 12 months and about £69.99. It is the machine in this set when dissolved solids are the job and you will empty a waste tank. It is the wrong buy if you only wanted chlorine taste out of a jug.
Pros
Cons
Best for: You want dissolved solids reduced, you have counter space for about 10 kg, and you will empty a waste tank.
Less suitable: You only want chlorine taste or a bit less kettle scale from a gravity jug.
Specifications
Common questions
Does the M6HG need plumbing?
The bullets say you fill the tank and plug in, with a Type G plug. They also say not to remove the glass pitcher during flushing. They do not describe a pipe connection.
What waste ratio does the listing state?
The bullets say 3:1 pure to drain, with a 5.5 litre tank split as 4 litres of feed and 1.5 litres of waste. That is the listing figure. UK reviews call emptying the waste a daily chore.
Do the reviews match this model?
The listing is 4.3 from 168. Several of the 50 stored texts describe other Waterdrop models. Fault notes that do name this unit include a dead unit, a leak, and hot water below the setpoint on a small pour.
The Waterdrop ED12W is an electric glass dispenser at about £99.99 listed at 5.3 litres with a three-month filter, and the amazon.co.uk line is 4.3 from 59 reviews. The specification says ion exchange, while the bullets say a five-stage filter and more than 70 contaminants, including chlorine, copper and limescale, with a supported TDS maximum of 500 ppm and no statement that TDS falls. It includes a power adapter, and the plug form is not stated, so you should not copy the Type G line from the M6HG onto this unit. At 35.5 × 26.4 × 32 cm and 5 kg it stays on the counter. UK texts mention a slow pump, an odd taste at the start, the price, and one unit that could not be operated and was returned. Hard-water reviews in that small file mention less kettle scale, and the replacement named on the page is WD-EWFLY. It suits a household that wants a larger glass reservoir and will accept a 59-review sample and an unstated plug. It is a poor buy if you need a confirmed UK plug on the listing or a deep review file.
Pros
Cons
Best for: You want more than a 2.5 litre jug on the counter, and you will check the plug when the parcel arrives.
Less suitable: You need a Type G plug printed on the page, or you are choosing on review depth.
Specifications
Common questions
Does the ED12W listing state a UK plug?
It says the unit is electric and includes a power adapter. It does not say Type G. The M6HG listing does say Type G. Do not copy that across.
What do the 59 reviews complain about?
UK texts mention a slow pump, an odd taste at the start, the price, and one unit that could not be operated and was returned. Hard-water reviews mention less kettle scale.
Which replacement filter is named?
The special-feature line says search WD-EWFLY. The title includes a 3-month filter.
Across 303 amazon.co.uk reviews, the AQUAPHOR white glass jug (model 522663) is a gravity filter at about £34.99 that holds 2.5 litres and ships with one Maxfor+ cartridge listed for 60 days or up to 200 litres. The bullets name chlorine, limescale, pesticides, lead, mercury, copper and microplastics, and this capture does not print an NSF standard number. The material line says glass, yet UK reviews call the flip-top lid cheap plastic and say the jug is not fully glass, which is the complaint that sends some buyers back. It is not electric, and the filter counter is battery-free. At 13.5 × 19 × 27 cm and 1.04 kg it is one of the smaller jugs in this set, though the filtered volume inside the 2.5 litre total is not stated. In this capture it is best value when you want a glass body and one cartridge at the lowest shelf price. It is a weak choice if you need a printed certificate number or a lid that feels like the rest of the jug.
Pros
Cons
Best for: You want the lowest-priced glass jug in this set for taste and some kettle film, and you will change the Maxfor+ on the earlier of 60 days or 200 litres.
Less suitable: You need a named NSF line, a mostly glass lid, or a stated filtered capacity.
Specifications
Common questions
Is the AQUAPHOR white jug only glass?
The material line says glass. The bullets describe a flip-top lid and a cartridge. UK reviews call the lid cheap plastic and say the jug is not fully glass.
How long is the Maxfor+ cartridge listed for?
The specification says 60 days. The bullets say up to 200 litres or 60 days. The capture does not print an NSF standard number.
Does this listing say it needs a plug?
No. It is a countertop jug with a battery-free filter counter. Dishwasher use in the bullets excludes the lid and the funnel.
The AQUAPHOR grey glass jug is the same 2.5 litre Maxfor+ idea at about £39.99, listed at 0.73 kg against 1.04 kg on the white jug, with 4.2 from 201 amazon.co.uk reviews. The filtration bullets match the white listing, and the Best Sellers Rank line is identical, so the two colours are not two independent popularity scores. UK reviews say it leaks unless you hold the lid while pouring, and another says the filter housing slides out. The special-feature line does not say leak-proof. The part number prints as 1, and the page does not describe the jug as electric. It costs about £5 more than the white jug for a colour change and a thinner review file. It suits you if you specifically want the grey body and you will pour with a hand on the lid. It is the wrong extra spend if the white jug’s price is why you were looking at AQUAPHOR.
Pros
Cons
Best for: You want this grey finish and you will keep a hand on the lid when you pour.
Less suitable: You are choosing on price, or you need a listing that claims to be leak-proof.
Specifications
Common questions
Is the grey AQUAPHOR jug a different review set from the white one?
The star line is 4.2 from 201 reviews. The white jug is 4.2 from 303. The Best Sellers Rank line matches. The stored review texts do not.
Does the listing say the grey jug leaks?
The special-feature line does not say leak-proof. One UK review says it leaks unless you hold the lid while pouring. Another says the filter housing slides out.
What is the part number?
The capture prints part number 1. Model name is AQUAPHOR. Weight is 0.73 kg.
The Aarke Purifier Large (model A1220) is about £119.98 for a borosilicate and stainless jug that you refill with carbon granules for four weeks, holding 1.7 litres filtered inside a 2.8 litre total. Across 942 amazon.co.uk reviews the line is 4.1. Reviews report a metallic taste until about 2 litres are flushed, granules reaching the filtered water, chips at the spout, and one handle that broke within three months. The bullets say you pour granules into a refillable stainless cartridge, yet the material list still includes ABS plastic and a recycled ocean-bound plastic handle. The flow line prints 5 litres per minute, far faster than the other jugs here, and no separate test is in the file. The supported TDS maximum is 500 ppm, and TDS reduction is not stated. It is the jug to look at when you want fewer disposable plastic cartridges and you will flush the first litres. It is not the top pick under a review-count rule, and it is a poor fit if granules in the glass would put you off.
Pros
Cons
Best for: You want a glass and steel jug you refill with granules, and you will discard the first pours.
Less suitable: You want the lowest price, or you will not tolerate loose granules or a chipped spout.
Specifications
Common questions
Does the Aarke use a plastic cartridge?
The bullets say you pour granules into a refillable stainless cartridge. The material list still includes ABS plastic and a recycled ocean-bound plastic handle.
What do UK reviews say about taste and granules?
Reviews report a metallic taste until about 2 litres are flushed, granules reaching the filtered water, spout chips, and one handle that broke within three months.
Is the 5 litres per minute figure a measured test?
It is the flow line on the amazon.co.uk specification. It is much faster than the other jugs in this capture. No separate test is in the file.
Shelf prices and stars are the amazon.co.uk snapshot of 19 October 2026 already stored for these nine listings. This is not a laboratory test. Public mains water is already required to be wholesome, so a jug is not scored as a safety device. The number on each row is the stored star rating times 20, divided by 10 for the 1–10 display: 4.6 is 9.2, 4.5 is 9.0, 4.3 is 8.6, 4.2 is 8.4 and 4.1 is 8.2. A count printed on two listings is one pool. No points are added for a certificate, and none are taken off for a shared review pool. The top pick is the largest review count that is not printed on a second listing. Best value is the lowest shelf price with a glass jug and one cartridge.
Amazon star score
100%The display score is the stored amazon.co.uk star rating times 20, then divided by 10. Review count is not added. A shared 17,655 line stays one pool in the written assessment and does not change the number. A missing certificate, a missing plug form, and a thin UK review sample stay in the assessment as well.
Buy the job before the glass. Filter glass on amazon.co.uk is a gravity jug, a granule refill, a mineral reservoir, an electric dispenser, or a countertop reverse-osmosis unit with a glass pitcher. Public mains water is already wholesome. Match the standard number to the job, read the filtered volume, and change the cartridge on time.
Filter glass, in this category, is a drinking-water filter with a glass reservoir: a gravity jug, a glass-and-steel jug you refill with granules, a larger mineral system, an electric glass dispenser, or a countertop reverse-osmosis unit with a glass pitcher. People in the UK buy one because they dislike chlorine taste or kettle scale, or because they do not want the water sitting in a plastic jug.
NSF/ANSI 42 is taste and odour. NSF/ANSI 53 is the health-effect claims listed for that model only. NSF/ANSI 58 is reverse osmosis. NSF/ANSI/CAN 372 means lead-free materials, not that lead is removed from the water.
The PT-72 bullets say that jug does not lower TDS. A flat pen does not mean the carbon failed. Dissolved solids are a different machine, with the matching standard.
The 4.6 from 17,655 reviews is printed on both PT-72 colours, and the texts include other jugs. That is one pool. The largest count here that is not duplicated that way is 4.3 from 4,649.
The first check is the job. Taste and some temporary hardness point to a carbon jug, with ion exchange if kettle scale is the complaint. Dissolved solids, or a named fluoride claim, need a different machine. NSF/ANSI 42 covers chlorine taste and odour. NSF/ANSI 53 covers health-effect claims listed for that model only. NSF/ANSI 58 is the reverse-osmosis standard. NSF/ANSI/CAN 372 means lead-free materials.
Read the filtered volume, not only the total fill. In this capture one jug prints 1.5 litres filtered and a specification capacity of 2.4 litres. A body near 25 cm deep is the size reviews say will miss a fridge door. Systems at 8.22 kg and 9.89 kg stay on the counter. Cartridge life is a litre limit and a time limit. BRITA’s cited instructions use 150 litres or 4 weeks. One glass listing says up to 200 litres or 60 days. Use whichever comes first.
Three typical situations, each with a recommendation from this comparison.
You rent, you want less chlorine taste, and you will change a cartridge. The AQUAPHOR white glass jug is best value at about £34.99, score 8.4, with one Maxfor+ listed for 60 days or up to 200 litres and 4.2 from 303 reviews. UK reviews say the lid is plastic. This capture prints no NSF number.
You want some effect on temporary hardness and a review file that belongs to one listing. The BRITA glass filter jug is the top pick at about £47.49, score 8.6, 4.3 from 4,649 reviews, with three MAXTRA PRO cartridges. The bullets name limescale. The lid and inner parts are plastic, and the capacity lines disagree.
You are comparing a jug near the mid-thirties with a countertop membrane as if they were the same product. The Waterdrop M6HG is the row for dissolved solids, about £429, score 8.6, with a Type G plug and a TDS reduction claim. You will empty a waste tank. A carbon jug will not do that job.
The top pick is the BRITA glass filter jug at about £47.49. It scores 8.6. The amazon.co.uk line is 4.3 from 4,649 reviews, the largest count in this set that is not printed on a second listing, and the box includes three MAXTRA PRO cartridges. Best value is the AQUAPHOR white glass jug at about £34.99, score 8.4, with one Maxfor+ cartridge and 4.2 from 303 reviews. The Waterdrop PT-72 rows score 9.2 because 4.6 times 20 is 92, but that 17,655 line is one shared pool, so it does not take either badge.
