Best pool chlorinator

Updated: 16.10.2026

You want one chlorinator to order, and the amazon.co.uk star lines will not do that job. A 4.5-star floater and a 4.4-star salt cell are different machines at £5.99 and £118.56. This page names the best pool chlorinator in this set as a top pick for a stated pool, and a best value for a small pool, each with the person who should skip it. The full table is the [pool chlorinator](/hub/pool-care/pool-chlorinator) comparison. The Products Compared editorial team set these two calls from the amazon.co.uk captures on 16 October 2026. There was no lab test. A qualifying purchase through our links can earn a commission at no extra cost to you.

Best only means best for a stated job

Best here means the listing that matches a job you can check. Amazon’s best-seller chart for Chlorine is dominated by tablet tubs, which is a different category from a machine that holds tablets or makes chlorine. Two jobs cover the calls below. The first is an above-ground pool on a 230 V cell, where you will confirm the litres in the manual because the winning listing omits them. The second is a paddling pool or a small frame pool, where a tablet holder is enough and you accept a lid that UK reviews say can open. A spa around 1,400 litres fails both jobs. If you have not chosen floater, feeder or cell, start with the pool chlorinator buying guide.

Top pick, Intex CG-26664

The top pick is the Intex CG-26664, ASIN B08DJ8VLD8, at £118.56, rated 4.4 from 1,055 reviews. The listing states 230 V. It does not state litres or grams per hour. Buy it when you have a pool pump, you want a salt cell rather than a weekly tablet top-up, and you will read your pool’s litres against Intex’s manual before the first bag of salt. Skip it when you cannot find a litre rating you trust. One UK review says the unit does not cover 17,000 litres, which is a buyer’s report, not Intex’s printed limit. Skip it for a Lay-Z-Spa of about 1,400 litres, and skip it if you have no return flow. Once it is in, test, salt and runtime are how to use a pool chlorinator.

Best value, FENRIR floater

The best value is the FENRIR floater, ASIN B08C56HWDZ, at £5.99, rated 4.5 from 2,439 reviews. OBOVO and CMXOAJ are £6.99. For a paddling pool you will test yourself, £5.99 matches the job, set against a £118.56 cell you cannot plumb. The limit is the lid. UK reviews describe lids that open, tablets that fall out, and fast dissolve. A trichlor tablet on vinyl can spot-bleach the liner. Skip FENRIR if you will not check it on swim days, if you want the dose on a return pipe, or if you want salt. In that last case the top pick, with the litre check, is the cell above.

Why the other high scores stay on the bench

Hayward CL200 is £129.40 and 4.6 from 3,420, with no United Kingdom review in the file and a weight field of 113 g. CL0200EURO’s 150 m³ limit stays on that trade code. CL200 suits you when you already want tablets on the pipe and a plumber will confirm the fit. Bestway’s 6 g/h cell states 26,498 litres, at least 1,249 litres per hour and 6 g/h, at £186.54. Amazon shows 5.0 from two reviews, too small to outrank 1,055 on CG-26664. Choose it when your pool is inside 26,498 litres and you want the cap printed on the listing. Intex 26670 states 12 g/h at £301.32, and a UK review says it arrived with a euro plug.

Common questions

Which is the best value, and who should skip it?
The best value is the FENRIR floater at £5.99, 4.5 from 2,439 reviews. It suits a small pool where you will add tablets, test the water and close the lid. Skip it if lids opening and tablets falling out are a risk you will not watch, especially on vinyl. Skip it if you want the dose on a return pipe or you want a salt cell. Five pounds does not buy the chlorine or a test kit.
Why is the Hayward CL200 not the top pick despite 4.6 from 3,420?
CL200 has the highest star count in the set and no United Kingdom review in the file. The amazon weight field reads 113 g, while CL0200EURO is a different, heavier trade code up to 150 m³. The top pick is a salt cell with a visible UK review pile and a stated 230 V mark. CL200 remains the inline feeder when you want tablets on the pipe and you will confirm the plumbing.
Why is Bestway 6 g/h not the top pick when it states litres?
Bestway 6 g/h states 26,498 litres, 6 g/h and at least 1,249 litres per hour, at £186.54. That cap is clearer than CG-26664. The star line is 5.0 from two reviews, too small to carry the top pick against 1,055 reviews. Shop prices of £599 RRP and £229.95 are not the amazon capture. Buy Bestway when you want the litres on the listing and your pool sits inside that cap.
Is Intex 26670 better because it states 12 g/h?
The 12 g/h line, with at least 2,650 litres per hour, is a real spec on the £301.32 listing. It does not settle the plug. A UK review says the unit came with a euro plug, while a Poolpro page claims a UK 3-pin plug and 56,800 litres. Keep those sources apart. A stated output with a disputed plug is a weaker buy than CG-26664 until the plug in the parcel is BS 1363.
What does the badge mean if there was no lab?
The comparison marks CG-26664 as the top pick and FENRIR as the best value from the listings and review notes in this capture. The Health and Safety Executive does not award a best chlorinator, and we did not run a lab. The labels mean the best match for the job on this page. They are not a measured chlorine result in your water.
