Above-ground pool, 230 V
You want a salt system whose title states 230 V, at the lowest salt-cell price in this set, and you will check litres against the manual in the box. The listing does not state output or pool volume.
Pool chlorinator comparison 2026
The best pool chlorinators, compared.
Top pick: Bestway Hydrogenic 6 g/h Best value: FENRIR 5 inch floater – Best value at about £5.99, with 4.5 from 2,439 reviews, for a pool that already uses tablets. Updated 16.10.2026.
A pool chlorinator on amazon.co.uk is one of three devices: a floating tablet holder, a plumbed tablet feeder, or a salt cell that makes chlorine as water passes a charged electrode. You tell them apart by tablets versus salt, by any stated filter flow, and by whether the plug suits a UK socket. Describes electrolysis turning salty water into a chlorine disinfectant, and the 26670 listing states 12 g/h even where the title says chlorine-free. Floaters here only hold tablets you buy separately. Salt cells need pool sodium chloride under BS EN 16401:2013, not table salt or seawater. UK mains are 230 V with a BS 1363 plug. A UK review says the 26670 came with a euro plug, and several listings never state a plug. The [salt cell or floater guide](/hub/pool-care/pool-chlorinator/sub/pool-chlorinator-salt-or-floater) keeps that choice in one place. HSE pool guidance covers pools the public uses, not a private domestic pool used only by the owner, family, and guests.

The best pool chlorinators in detail
Our view
The Bestway Hydrogenic 6 g/h is listed at about £186.54 with 5.0 from 2 reviews. Bullets state 6 g/h, pools up to 26,498 litres, minimum flow 1,249 litres, a timer, a self-cleaning mode, and dimensions 34 × 27 × 26 cm. The box includes 50 test strips. Voltage and plug are not stated. The one UK review in the file is positive for a pool the reviewer puts at 9,150 litres. A star line of 5.0 from 2 is a very small sample.
Pros
- 6 g/h and 26,498 litres are both stated
- 50 test strips included
- Self-cleaning mode stated
- One positive UK review in the file
Cons
- Only 2 reviews on the star line
- Plug and voltage not stated
- Salt not included
- Flow unit per hour is not printed beside 1,249 L
Best for: An above-ground pool inside 26,498 litres whose pump meets the stated minimum flow.
Less suitable: A buyer who needs a stated UK plug or a large UK review sample. Neither is in the capture.

Common questions
What pool size does the listing state?
Above-ground pools up to 26,498 litres (7,000 gal.), with a minimum flow of 1,249 litres (330 gal.).
What is in the box?
One chlorinator and 50 test strips for chlorine, alkalinity, and pH. Salt is not named as included.
How many UK reviews are in the file?
One. The reviewer describes a 12 ft Bestway pool they state as 9,150 litres and 34 kg of salt. The star line is 5.0 from 2.
Our view
The NYANS salt cell is listed at about £320.57 with 5.0 from 2 reviews. The title string says 25 g/h and without app control, plus 15K–30K with no unit. The bullets say WiFi, an app, pipes of 1.5 inch and 2 inch, IPX5, and polarity reverse every 4 hours. Voltage is absent. The weight field is 1.3 kg. Both reviews in the file are German, so they are not UK opinion. A star line of 5.0 from 2 is a very small sample.
Pros
- Pipe sizes and IPX5 are stated
- Output adjustable from 5 to 100 percent, in the bullets
- Self-cleaning plates claimed
- about £320.57 is the captured price
Cons
- Title and bullets disagree about the app
- No voltage
- No UK reviews
- Only 2 reviews, both German
Best for: A plumbed pool whose pipes match 1.5 inch or 2 inch, if you can verify voltage and the app from the box.
Less suitable: A buyer who needs a clear UK plug and a settled app claim. The listing contradicts itself.

What pipes does the listing name?
2 inch, given as 60.3 mm outside diameter, and 1.5 inch, given as 48.3 mm outside diameter. IPX5 is claimed. Voltage is not stated.
Are the two reviews from the UK?
No. Both are from Germany. One mentions a Tuya app and a 50 mm pipe. They are not UK opinion.
Our view
The Hayward CL200 is listed at about £129.40 with 4.6 from 3,420 reviews. The title includes a mounting base. Bullets name a dial, an Easy-Lok cover, ABS, and a Viton seal. Pipe size and pool volume are absent. The weight field reads 113 g, which is the figure printed and is not a credible weight for this feeder. The file has no UK review. Do not copy the trade code CL0200EURO, at 4 kg and up to 150 m³, onto this amazon.co.uk listing.
Pros
- 4.6 from 3,420 reviews
- Mounting base in the title
- Dial adjustment stated
- about £129.40
Cons
- No UK reviews in the file
- No volume or pipe size
- Weight field reads 113 g
- Not a salt cell
Best for: A plumbed pool where you want a tablet canister and you will confirm pipe size from the manual, not from this listing.
Less suitable: A buyer who needs UK review text or a stated cubic-metre limit. Neither is in the file.

Common questions
Does the CL200 listing include a mounting base?
Yes. The title says with mounting base.
What tablets does it name?
Large or small slow-dissolving tablets. The highlight line says trichlor or bromine. Pool volume is not stated.
Is the 113 g weight credible?
That is the figure in the listing field. It is captured as printed and is not a credible weight for this feeder.
Our view
The Hayward CL200EF is listed at about £119.94 with 4.6 from 244 reviews. Bullets describe a dial, an Easy-Lok cover, ABS, and a Viton seal, and call it an update of the CL200. The weight field is 1.81 kg. Volume and pipe size are not stated. The file has no UK review. US reviews praise the dial and one says the mounting-base tabs broke. Those US reviews are not UK opinion.
Pros
- about £119.94
- 4.6 from 244 reviews
- Dial and Easy-Lok cover stated
- Weight field 1.81 kg, unlike the CL200 field of 113 g
Cons
- No pool volume or pipe size
- No UK reviews in the file
- Tablets not included
- US review of broken base tabs
Best for: A return line you can already plumb, if the manual in the box matches your pipe.
Less suitable: A buyer who needs a stated litre capacity before ordering. The listing does not give one.

No. The listing is an in-line feeder for slow-dissolving tablets, and the bullets call it an update of the CL200.
What pool size does the listing state?
None. Pipe size is also absent.
Are there UK reviews in the capture?
No. The reviews in the file are from the United States and Canada. One US review says the base tabs snapped. That is not UK opinion.
Our view
The OBOVO floater is listed at about £6.99 with 4.6 from 88 reviews. It is a retractable ABS dispenser for 1 inch chlorine or bromine tablets, with a lockable cap. The weight field is 80 g. Nineteen UK reviews mostly say it does the job. More than one calls it cheap or flimsy, and one says the lid is awkward and residue appeared after a month.
Pros
- about £6.99
- 4.6 from 88 reviews
- Chlorine or bromine stated
- Nineteen UK reviews
Cons
- Cheap feel in UK reviews
- Lid awkward in one UK review
- Tablets not included
- No stated tablet count on the listing
Best for: A paddling pool or small spa that uses 1 inch tablets.
Less suitable: A buyer who wants a heavy, rigid body. UK reviews mention a flimsy feel.

Common questions
Will it take bromine tablets?

How many tablets do UK reviews mention?
One UK review says it holds five. The listing itself does not state a count.
Is it mains powered?
No power supply is stated. You place it in the water.
Our view
The FENRIR floater is listed at about £5.99 with 4.5 from 2,439 reviews and rank 32 in Chlorine. It is an ABS holder for tablets up to 1.5 inch, with a claimed lock and adjustable ports. The weight field reads 10 g. Fifty UK reviews praise the price and the float. They also report a lid that opens, a full load gone by the next day, and tablets that fell out. In this set it is the best value: a tablet holder at about £5.99, which does not make chlorine.
Pros
- about £5.99
- 4.5 from 2,439 reviews
- Fifty UK reviews in the file
- No mains plug to fit
Cons
- Does not make chlorine
- UK reviews of the lid opening
- Weight field reads 10 g
- Tablets not included
Best for: A small pool or hot tub where you already buy tablets and you will test the water.
Less suitable: Anyone who needs the lid to stay locked. UK reviews say it can pop off.

Up to 1.5 inch tablets, with an inlet of 6 cm. The title says 5 inch for the floater itself.
What do UK reviews say about the lid?
Among 50 UK reviews, more than one says the top pops off and tablets fall out. One report includes staining on the pool bottom.
Our view
The CMXOAJ floater is listed at about £6.99 with 4.5 from 563 reviews. It is a stretchable 5 inch ABS body with a locking cap. Bullets allow 20 g to 100 g tablets, 1 inch tablets whole, and say 3 inch tablets must be crushed. Fifty UK reviews praise adjustment and clear water. One calls the dose uncontrollable, one says tablets were missing, and one reports a crack in hot-tub water.
Pros
- about £6.99
- 4.5 from 563 reviews
- Adjustable vents that some UK reviews say stay set
- Hot tub named on the listing
Cons
- Tablets not included
- Listing tells you to crush 3 inch tablets
- One UK review of a crack in hot water
- One UK review of an unstable dose
Best for: A pool or hot tub that already uses 1 inch tablets.
Less suitable: A buyer who only has 3 inch tablets and does not want to crush them.

Common questions
Can this floater take a 3 inch tablet?
The bullets say a 1 inch tablet goes in whole and a 3 inch tablet needs to be crushed. Crushing is the listing’s instruction, not a safety verdict.
Are the tablets in the box?
The listing does not include them. One UK review says they were not in the parcel.
Does it suit a hot tub?
The title and the bullets say hot tub. UK reviews include hot-tub use, and one unit cracked in hot water.
Our view
The Intex CG-26664 is listed at about £118.56 with 4.4 from 1,055 reviews. The title states 230 V and model 26664. The bullets do not state grams per hour, litres, salt dose, or plug type. The weight field is 2.5 kg. Five UK reviews are in the file: easy connection, a rejection for a 17,000 litre pool, and a return citing a heavy salt load on a pool about 4 m by 2 m. In this set it is the top pick: the lowest salt-cell price, with 230 V in the title and UK reviews in the capture. It is not a lab ranking.
Pros
- 230 V is in the title
- about £118.56, the lowest salt-cell price in this set
- 4.4 from 1,055 reviews
- UK reviews in the file
Cons
- Output and pool volume not stated
- One UK review says it does not cover 17,000 litres
- Plug type not stated
- Salt dose is not a listing field
Best for: An above-ground pool where 230 V is what you need and you will check volume against the manual in the box, because the listing does not state litres.
Less suitable: A pool you already know is about 17,000 litres, which one UK review says this model does not cover.

Do the UK reviews say it suits every pool?
Five UK reviews are in the file. One says it does not cover a 17,000 litre pool. Another returned it because a pool about 4 m by 2 m needed a large salt dose.
Is the salt dose printed on this listing?
No. The salt figures in the file come from a UK review, not from a specification field.
Our view
The Briidea BR-159 is listed at about £169.89 with 4.4 from 66 reviews. The title caps it at 2,000 gallons for hot tubs and swim spas and says chemical-free. Bullets describe a titanium cell, a timer, and no plumbing, and say the cell makes chlorine from salt. Voltage, salt dose, and grams per hour are absent. The weight field is 1.08 kg. Reviews in the file are from the United States and Canada, including a note that pH rose. Those reviews are not UK opinion.
Pros
- No plumbing claimed
- 4.4 from 66 reviews
- Timer and salt indicator stated
- about £169.89
Cons
- No UK reviews in the file
- Voltage not stated
- Gallons only, no litres
- Title says chemical-free while the cell makes chlorine
Best for: A tub inside the stated 2,000 gallons, if you accept a drop-in cell and a missing voltage line.
Less suitable: A UK buyer who needs a stated 230 V plug or UK reviews. The file has neither.

Common questions

What size does the title allow?
Hot tubs and swim spas up to 2,000 gallons. The listing does not convert that to litres and does not state a salt dose or a voltage.
Is it chemical-free?
The title says chemical-free. The bullets say the cell makes chlorine from salt. The file has no UK review.
Our view
The Intex 26670 is listed at about £301.32 with 4.3 from 1,090 reviews. Bullets state 12 g/h, 220–230 V, a 24 hour timer, salt of about 3 kg per cubic metre, and a filter of at least 2,650 l/h. The title also says chlorine-free, which conflicts with 12 g/h. A listing line claims up to 70 percent less chlorine requirement. That was not measured here. Three UK reviews mention a working 7 by 4 m pool, a euro plug, and salt errors.
Pros
- 12 g/h, salt dose, and minimum flow are all stated
- 4.3 from 1,090 reviews
- 24 hour timer and a display
- UK reviews in the file
Cons
- about £301.32
- UK review of a euro plug
- UK review of salt errors and scarce UK parts
- Title says chlorine-free while output is 12 g/h
Best for: An above-ground pool whose pump is at least 2,650 l/h, if you can fit the plug the parcel actually contains.
Less suitable: A buyer who needs a BS 1363 plug stated on the listing. It is not stated, and a UK review says euro plug.

What salt and flow does the listing state?
About 3 kg per cubic metre, also written as 2.5–3.5 g/l, and a filter of at least 2,650 litres per hour. Voltage is 220–230 V.
What plug do UK reviews mention?
One of three UK reviews says it comes with a euro plug. Another says parts were hard to find in the UK after salt errors.
Our view
The Bestway Hydrogenic 0.5 g/h is listed at about £185.57 with 4.1 from 42 reviews. Bullets state 0.5 g/h, up to 1,400 litres, about 8 hours on a rechargeable battery, and test strips. The dimensions line reads 50 × 50 × 50 cm and 990 g. The power field says ac. The file has no UK review. Non-UK reviews often mention charging, and they are not UK opinion.
Pros
- 0.5 g/h and 1,400 litres are both stated
- Test strips included
- One-touch control stated
- No pipework described
Cons
- about £185.57 for 0.5 g/h
- No UK reviews in the file
- Battery versus ac conflict
- Dimensions 50 cm cube at 990 g, as printed
Best for: A Lay-Z-Spa or tub inside 1,400 litres, if you can live with charging.
Less suitable: A frame pool. The output and the volume line are spa-sized.

How we compared
Eleven amazon.co.uk listings are on this page: three floaters, two inline feeders, and six salt devices. Prices, stars, and review counts are the figures in those captures. There is no laboratory test. The card scores are the display scores for those listings. The weights follow the buying order in the digest: type, then size and flow, then what you add, then the plug, then whether you can test the water. They sum to 100. Listings with no UK reviews are not treated as UK opinion.

Pool chlorinator buying guide
A pool chlorinator here is a floater, an inline tablet feeder, or a salt cell. The eleven amazon.co.uk listings split that way, from about £5.99 to about £320.57. Saltwater is not chlorine-free: the cell makes chlorine. Read the stated litres, the filter flow, and the plug before the shelf price. Tablets and pool salt are extra. One or two reviews are not a large UK sample, and reviews from outside the UK are not UK opinion.
What is a pool chlorinator?
A pool chlorinator in this set is a floater, an inline feeder, or a salt cell. A floater only holds tablets. The FENRIR, CMXOAJ, and OBOVO units are that product, at about £5.99 to £6.99. An inline feeder doses slow-dissolving tablets on the return pipe. That is the Hayward CL200 at about £129.40 and the CL200EF at about £119.94. A salt cell makes chlorine while water passes a charged electrode, and it needs salt in the water. Saltwater is not chlorine-free.
Best for
- A small frame or paddling pool where you already buy tablets and you will test the water
- An above-ground pool whose pump meets a stated flow, if the listing actually prints that flow
Not ideal for
- Anyone who wants a salt pool with no chlorine in the water
- A buyer who needs a BS 1363 plug printed on the listing when the file does not state one
Mistakes to avoid
- 1
Calling a salt cell chlorine-free
SPATA describes electrolysis turning salty water into a chlorine disinfectant. Intex 26670 states 12 g/h in the same listing that says chlorine-free. Briidea’s bullets say the cell makes chlorine from salt.
- 2
Copying one salt dose onto every brand
Intex 26670 states about 3 kg per cubic metre. The CG-26664 listing does not state a salt dose. BS EN 16401:2013 covers pool salt for electrochlorinators. Table salt and seawater are not that product.
- 3
Using CL0200EURO figures on the amazon CL200
UK trade sells CL0200EURO at 4 kg and up to 150 m³. The amazon.co.uk CL200 listing does not state pool volume or pipe size, and its weight field reads 113 g. Do not copy those trade limits onto this ASIN.
What to weigh up
Type: floater, feeder, or salt cell
HighThe first split is what the device actually does. A floating dispenser, here FENRIR, CMXOAJ, and OBOVO, only holds tablets you add. It has no mains plug and no chlorine output of its own. An inline feeder, the Hayward CL200 and CL200EF, doses slow-dissolving tablets from a canister on the return pipe, with a dial and an Easy-Lok cover. It is not a salt cell. A salt generator, drop-in cell, or spa salt floater makes chlorine from salt in the water.
Stated size, flow, and the UK plug
HighRead the limit the listing prints, and leave a blank as a blank. Bestway 6 g/h states above-ground pools up to 26,498 litres and a minimum flow of 1,249 litres. Intex 26670 states 12 g/h, about 3 kg of salt per cubic metre, and a filter of at least 2,650 l/h, at 220–230 V. Bestway 0.5 g/h states 0.5 g/h and up to 1,400 litres. The CG-26664 title states 230 V and does not state litres or grams per hour. One UK review says it does not cover 17,000 litres.
Which option suits you?
Three typical situations, each with a recommendation from this comparison.
Small pool on tablets
You already buy tablets and you will test the water. A floater only holds them. This one is about £5.99, and UK reviews include a lid that can open.
Above-ground pool with a stated flow
Your pump can meet a stated minimum flow and the pool is inside 26,498 litres. This listing prints 6 g/h, that volume, and 50 test strips. Voltage and plug are not stated.
Common questions about pool chlorinators
Which pool chlorinator is the top pick?
The top pick in this set is the Intex CG-26664, at about £118.56 with 4.4 from 1,055 reviews. The title states 230 V. The bullets do not state grams per hour, pool litres, a salt dose, or a plug type. Five UK reviews are in the file. One says it does not cover 17,000 litres. It leads because it is the lowest salt-cell price here with UK reviews in the capture. It is not a lab ranking.
How much does a pool chlorinator cost?
On these amazon.co.uk captures, floaters are about £5.99 to £6.99. The middle band is about £118.56 to £186.54, covering the Intex CG-26664, both Hayward feeders, the Briidea drop-in cell, and both Bestway units. The Intex 26670 is about £301.32 and the NYANS cell is about £320.57. These are shelf prices from the raw files, not a shop survey. Tablets or pool salt cost extra.
What should I check before I buy a pool chlorinator?
Start with the type. A floater only holds tablets, an inline feeder doses tablets on the return pipe, and a salt cell makes chlorine and needs salt in the water. Then read any stated litres and filter flow. Bestway 6 g/h states up to 26,498 litres and at least 1,249 litres of flow. Intex 26670 states at least 2,650 l/h. Also check 230 V and whether a BS 1363 plug is actually stated. Several listings leave the plug blank.
Is a salt pool chlorine-free?
No. A salt cell makes chlorine. SPATA describes electrolysis turning salty water into a chlorine disinfectant. The Intex 26670 title says chlorine-free, and the same listing states 12 g/h. The Briidea title says chemical-free, while the bullets say the cell makes chlorine from salt. Do not repeat the 26670 line about up to 70 percent less chlorine as a measured saving. You still test free chlorine and pH.
Do these pool chlorinators include chlorine tablets?
The floaters do not include tablets. FENRIR, CMXOAJ, and OBOVO are holders, and one UK review of the CMXOAJ says the tablets were not in the parcel. Hayward CL200 and CL200EF are inline feeders for slow-dissolving tablets, also bought separately. The tablet tubs are a different comparison: chlorine tablets for a pool. Follow the biocide label, keep tablets in the original container, away from children, and never mix acid with a chlorine donor.
Will the plug fit a UK socket?
UK mains are 230 V with a BS 1363 plug. The CG-26664 title says 230 V and does not name the plug. The Intex 26670 states 220–230 V, and one of three UK reviews says the parcel had a euro plug. Bestway 6 g/h, Briidea, and NYANS do not state voltage. Do not invent a BS 1363 plug the listing does not print. Replacing a non-UK plug is a job for a competent person.
When should I call a professional?
Call a professional to cut pipe near a heater, to add salt where there is stainless steel or an unknown heat exchanger, to acid-clean a cell, or to replace a non-UK plug. Do not copy one salt dose onto every brand. Intex 26670 states about 3 kg per cubic metre. The CG-26664 file does not print a salt dose as a specification. Do not give the Hayward CL200 the 150 m³ or 4 kg figures from the trade code CL0200EURO.
How do I know the chlorine level is right?
PWTAG shows that pH changes how much free chlorine is the active form, so a holder or a cell without a test is a guess. The Bestway boxes in this set include test strips. The floaters do not. Read free chlorine and pH on the kit you use, not against a title that says chlorine-free. How often to test pool water sets out that routine. HSE still expects you to follow the biocide label.
Our verdict
The top pick is Hayward CL200, with the highest score in this comparison (9.2 out of 10, from 3,420 amazon.co.uk reviews). The best value is the FENRIR 5 inch floater, about £5.99 with 4.5 from 2,439 reviews. It holds tablets up to 1.5 inch and does not make chlorine. UK reviews praise the price and also report a lid that opens.
