The best ultrasonic foggers, compared.
Top pick: MUALROUS 12-head 8.5 L/h Best value: MOXTOYU 12-LED mist maker – £14.99 with 4.1 from 209 reviews, lights and a splash guard, close to the cheapest disc and well ahead of the short review files. Updated October 2026.
You looked up an ultrasonic fogger in pest control. A ceramic disc vibrates under the surface and throws a cool cloud of fine droplets, from a 24 V head or a 45–48 V board on a mains adapter. People use them as a pond ornament, a cauldron, or a humidifier for a tank or a glasshouse. Ultrasonic on these pages means the disc frequency. None of the twelve shows an HSE number. What separates them is head count, a float for deep water, spare discs, a splash guard, a stated UK plug, and a supply you keep dry. Both files include early failures and a shock report with a hand in the water. An ultrasonic fogger in this UK set is a water mist maker. The same search word also pulls in sound repellers. How to choose is set out in the [water disc versus a pesticide fogger](/hub/pest-control/ultrasonic-fogger/sub/ultrasonic-fogger-vs-insect-fogger).

Question 1 of 2
What are you filling with mist?
The MUALROUS 12-head kit is £97.99, and the bullet says up to 8500 ml/h, at least 9 m² indoors and 7 m² outdoors, with 12 spare discs, a wrench, a buoy, and a 400 W supply. The same bullet marks the supply IP67 and then says do not immerse it. Working depth is 6–7 cm on the board, and the buoy is for water deeper than 7 cm. It also says the unit stops above 55 °C, and a low-water stop is stated. The star line is 5.0 from two reviews, and neither text is from the United Kingdom: one is Ireland and one is the United Arab Emirates. The package weight is 2.93 kg. A five-star pair that small is not a durability test. Follow the do-not-immerse line rather than the IP mark.
Pros
Cons
Best for: A pond or greenhouse where you want spare discs in the box and you will keep the 400 W block on the bank
Less suitable: Anyone reading 5.0 from two reviews as a UK quality test, or a Halloween cauldron
Specifications
Common questions
Can the MUALROUS power supply go in the pond?
No. The bullet marks it IP67 and then says do not immerse it.
What working depth does the bullet give?
6–7 cm on the board, and the buoy if the water is deeper than 7 cm. It also stops above 55 °C.
Are the two five-star reviews from the UK?
No. One text is from Ireland and one is from the United Arab Emirates.
The Aobiforu silver fogger is £14.99, and the bullet claims at least 400 ml/h with 12 LEDs that change colour at random. It also says the mister turns off when the water is low, and that a container lower than 30 cm may splash. The star line is 4.3 from eight reviews. The bullets describe 24 V, while the power-source attribute says no, so those two lines disagree and the live page is the one to read before you assume a plug. A float, a splash guard, and spare discs are not stated. The attribute size is 3 x 3 x 4 cm at 230 g, which is a compact head rather than a cauldron kit. The 400 ml/h line is a bullet, not a UK lab result.
Pros
Cons
Best for: A vase, tank, or Halloween pot taller than 30 cm if you can accept a short review file
Less suitable: A shallow tray, or anyone who needs a stated UK plug
Specifications
Common questions
How much mist does the Aobiforu bullet claim?
At least 400 ml/h. It also says a container lower than 30 cm may splash.
Does the listing say it needs mains power?
The bullets describe 24 V. The power-source attribute says no. Those two lines disagree.
Is there a low-water cut-off?
The bullet says it turns the mister off when the water level is low.
The Mxmoonant 350 ml/h kit is £18.99, and the box lists the fogger, a UK adapter, a splash guard, a float, three 20 mm ceramic discs, and a key. The model field says no LED, and a bullet points you to a second ASIN for an LED version, though that twin listing also says no LED. It is 4.2 from 18 reviews. One review says the water sensor works. Two UK reviews still could not see how to fit the spare discs, so the key and the paper are not obvious to every buyer. The head is stainless steel, the file weight is 440 g, and the part string is CCY-111-UK. The float is the part the bare £13 discs do not state. The 350 ml/h line remains a listing claim.
Pros
Cons
Best for: One head for a pond or vivarium when you want spare discs and a float in the same box and you do not need lights
Less suitable: A lit cauldron, or anyone looking for a confirmed LED version of this part
Specifications
Common questions
Are spare discs in the Mxmoonant 350 ml/h box?
The bullet says three 20 mm ceramic discs and a key. Two UK reviews still could not see how to fit them.
Does this listing have LEDs?
The model field says NO LED. The bullet points you to ASIN B0F2XX3L3Y for an LED version.
What is the part number?
CCY-111-UK, the same part string as B0F2XX3L3Y.
This second Mxmoonant listing uses the same title and the same part, CCY-111-UK, at the same £18.99, with the same stated kit of a UK adapter, a splash guard, a float, three 20 mm discs, and a key. The model field again says no LED. It is 4.2 from nine reviews, and the file weight is 390.09 g rather than 440 g. One of the two UK review texts wishes the colours would stop cycling, which contradicts the model field, so this ASIN is not a confirmed LED upgrade. Those two texts use it as a water feature and as a Halloween cauldron. A low-water stop is not stated on this row. Buy one of the two listings, and check the live photos for lights before you trust either line.
Pros
Cons
Best for: Only if this ASIN is the one in stock and the live photos match the lights you actually want
Less suitable: Anyone choosing between the two Mxmoonant rows on the model field alone
Specifications
Common questions
How is this Mxmoonant listing different from B0F23YKRB5?
Same title, price, and part CCY-111-UK. This file weighs 390.09 g, not 440 g, and it has 9 ratings rather than 18.
Does the model field say it has lights?
No. It says NO LED. One of the two UK reviews wishes the colours would stop cycling.
What did those two UK reviews use it for?
A water feature, and a Halloween cauldron.
The BrightArk puts a 20 cm plastic cauldron in the box with the 24 V mist maker and a float, at £21.99. The RGB change is automatic, and the bullet says there is no remote, so you cannot lock one colour. It is 4.2 from six reviews, only two of them labelled United Kingdom and four labelled United States. One US text says the fog spills down rather than rising out of the pot. Plug type is not stated. The head is ABS plastic, the package is 318 g, and there is no ml/h figure and no spare-disc count. If you already own a cauldron, you are paying for a pot. If you do not, this is the only included pot in the twelve.
Pros
Cons
Best for: A Halloween setup where the 20 cm pot has to arrive in the same box
Less suitable: A garden pond, or anyone who wants to hold one light colour
Specifications
Common questions
Does the BrightArk box include the cauldron?
Yes. The bullet describes a 20 cm plastic witch cauldron plus the float.
Can you pick one light colour?
The bullet says the RGB change is automatic and there is no remote.
Are all six reviews from the UK?
No. Two texts are United Kingdom and four are United States. One US text says the fog spills down rather than rising out of the pot.
The MOXTOYU mist maker is a 24 V disc at £14.99 with 12 colour-changing LEDs and a built-in splash guard, and amazon.co.uk shows 4.1 from 209 reviews. The model code is CM-20LET, the same string as the Olutula listing. A UK review says you supply the water container yourself. Other texts describe early failure and a fussy water level, and one says not to put a hand in the water while it is on because of a shock. A 265 W figure sits only in an attribute block beside a humidistat and a 56-minute runtime, and the five bullets do not repeat those parts, so do not treat 265 W as measured power on a 220 g head. The material line disagrees as well: the bullet says stainless steel and an attribute says aluminium.
Pros
Cons
Best for: A fountain or Halloween pot you already own, if you want lights, a guard, and a large review sample at £14.99
Less suitable: Anyone who needs a float, spare discs in the box, or a supply that can go in the water
Specifications
Common questions
Does the MOXTOYU file include a water container?
No. A UK review says the instructions suggest one, and you use your own container.
Why is 265 W hard to use?
It sits in an attribute block with humidistat, a cartridge, and a 56 minute runtime. The five bullets do not repeat those parts.
What safety note is in the UK reviews?
One review says not to put a hand in the water while it is on, because of a shock. Other texts describe early failure and a fussy water level.
The GlintBay mini is £14.99, and the bullet names a UK plug, a splash guard, 12 flashing LEDs, and 300 ml/h. Amazon shows 4.0 from 15 reviews. The same bullet says to keep the fogger 3–5 cm above water level and that it stops if the water runs low. The cauldron is not in the box, and the listing only says the head fits cauldrons. UK reviews say it wets the table, that the head is light and drifts, and that one unit only ran when the plug was not fully in. At 190 g and about 4.5 cm across, a ripple moves it. Voltage is not in the technical block even though the plug is named. The 300 ml/h figure is a bullet, not a measured UK test.
Pros
Cons
Best for: A Halloween cauldron you already own, where a stated UK plug matters more than spare discs
Less suitable: An open pond, because reviews say this light head drifts and the file has no float
Specifications
Common questions
What water depth does GlintBay state?
The bullet says keep the fogger 3–5 cm above water level, and that it stops if the water runs low.
Does it include a cauldron?
No. The bullet says it fits cauldrons. The cauldron is not in the box.
What went wrong in the UK reviews?
It wets the table, it is light and drifts, and one unit only ran when the plug was not fully in.
The Olutula 24 V disc is £13.99 with 12 colour-changing LEDs and a built-in splash guard, and the extract ranks it first in Pond Foggers. That rank sits on 4.0 from nine reviews, a small sample next to the files with 200 or more. Three of the five review texts use it in a Halloween cauldron or a display, and one mentions a bit of spitting. The head is listed at 190 g, with stainless steel in the bullet, and the model string is CM-20LET, the same code as the MOXTOYU row under a different brand. A UK plug is not stated. Head count and spare discs are not in the extract either. The lights change colour. They do not add a stated mist volume.
Pros
Cons
Best for: A Halloween display or fountain where you want lights and a splash guard on a disc around £14
Less suitable: A pond that needs a stated float, or anyone who reads a Pond Foggers rank as a durability test
Specifications
Common questions
Does this Olutula unit have lights?
The title and the bullet say 12 colour-changing LED lights.
Is a splash guard included?
Yes. The listing calls it built in.
What did the UK reviews use it for?
Three of the five texts use a Halloween cauldron or display. One mentions a bit of spitting.
The Wandou 24 V mist maker is a single disc at £12.99, sold as the atomizer plus a transformer, and the title states a UK plug. Across 296 amazon.co.uk reviews it sits at 3.9, the largest sample in this set. The bullet says it stops when the water falls below the sensor. Spare ceramic discs are not in the kit bullet, so the first worn disc is a separate buy. In the first 50 review texts, units die after days or months and some supplies run hot. One reviewer reported a shock with a hand in the water while the unit was on, so unplug it before you top the bowl up. It throws a cool water mist for a pond, a tank, or reptile humidity, and it does not apply an insecticide.
Pros
Cons
Best for: A bowl or tank where you want the most-reviewed cheap single disc and you will unplug it before your hands go in the water
Less suitable: Anyone who needs spare discs in the box, or a stated float for a deep pond
Specifications
Common questions
Does the Wandou listing include a UK plug?
The title says UK plug. The kit bullet is the atomizer and the transformer.
Will it switch itself off if the water drops?
The bullet says it stops when the water level is lower than the sensor.
What did UK reviewers report when it failed?
Across the first 50 texts, units die after days or months, some supplies run hot, and one reviewer reported a shock with a hand in the water.
The Walfront is the only four-head file in this comparison, at £41.93, on DC 45–48 V, with 1.7 MHz in the title and a claimed area of 2 m². There is no ml/h figure. There is also no Customer Reviews line in the extract, which is why the listing score sits at 18. The bullet says IP67 and a 1.5 m cable. The head is stainless steel in the bullet, and the package is 540 g. A float, a splash guard, spare discs, lights, and a low-water stop are not stated. Four heads is a step past a cauldron disc, and it is not an 8-litre 12-head board. With no UK review text, you are buying the title.
Pros
Cons
Best for: A buyer who specifically wants four heads and will accept a listing with no UK reviews
Less suitable: A first fogger, or anyone using a star average to choose
Specifications
Common questions
How many heads does the Walfront title state?
Four, at DC 45–48 V, with 1.7 MHz oscillation.
Is there a UK star rating in the extract?
No Customer Reviews line and no review text.
What area does the title claim?
2 m². There is no ml/h figure.
The Rengue 12-head board is £89.60, and the bullet claims 9000 ml/h, up to 9 m² indoors and 7 m² outdoors, with a float, a 1.5 m cable, and a 400 W IP67 supply. Independent fuses are stated. The board is 304 stainless steel, and disc life is claimed at 3,000–5,000 hours without a spare count in the box list. There is no Customer Reviews line, and the file’s first-available date is 22 June 2026. The page asks about koi and does not answer. The word appears as a place name in a use bullet, not as a welfare test. An immersion warning is not in this file, so the IP67 line is not a reason to sink the supply. The square metres are bullets, and wind still clears a cloud.
Pros
Cons
Best for: A sheltered pond or a greenhouse humidity job if you accept an unreviewed 12-head board at £89.60
Less suitable: Anyone who needs UK reviews, a stated spare-disc count, or an answer on fish
Specifications
Common questions
What output does Rengue claim?
9000 ml/h, and up to 9 m² indoors and 7 m² outdoors. Both figures are bullets.
Does the page say it is safe for koi?
No. Koi appears only as a place name in a use bullet. The page question is not answered.
Is there a review sample?
No Customer Reviews line. First available in the file is 22 June 2026.
The Mxmoonant 12-head board, model CCY-01A-SXL, is £129 and claims 8400 ml/h from 12 heads, with 10 spare discs, a key, and a float for water deeper than 8 cm. The bullet says continuous running should not exceed 6 hours, and the runtime attribute matches that. The 400 W transformer takes 175–265 V down to 45–48 V, is marked IP67, and the bullet says it is not submersible. The board itself is described as IP68. A low-water stop is stated below the sensor stick. There is no Customer Reviews line and no review text. The board is 304 stainless steel, 3.88 kg, and 32.5 x 8.5 x 2.8 cm, with an aluminium transformer housing. It is the dearest file in the set, and that price does not come with a UK durability record.
Pros
Cons
Best for: A large sheltered water feature if you want spare discs and a written run-time cap and you can accept no reviews
Less suitable: A cauldron, a first try, or anyone who treats the highest price as a tested result
Specifications
Common questions
How long does Mxmoonant say to run the 12-head board?
The bullet says continuous operation should not exceed 6 hours. The runtime attribute is 6 hours.
Is the transformer submersible?
No. The bullet says the IP67 transformer is not submersible. The board itself is described as IP68.
Is there a UK review sample?
No Customer Reviews line and no review text in the extract.
Twelve amazon.co.uk listings are on this page. Each listing score uses the star line, the review count, and a flat completeness mark from the product extract. A missing Customer Reviews line scores low. The scores are not a laboratory test of mist volume, disc life, or electrical safety. The top pick and the best value follow the awards already on those extracts. Output, area, and wattage figures stay listing claims.
Amazon star rating
40%The amazon.co.uk star line, scaled as part of the listing score. A high star average on two reviews does not outrank a larger sample. This is not a lifespan test.
Review count
35%How many amazon.co.uk reviews sit on that ASIN. The 296-review and 209-review discs outrank short files. A missing Customer Reviews line adds nothing here.
Listing completeness
25%A flat mark for whether the extract states the parts a buyer needs: heads, plug or adapter, float, spare discs, and a low-water note. Missing lines stay blank. They are not filled in.
An ultrasonic fogger here is a water mist maker, usually filed on amazon.co.uk under Pond Foggers. Choose the head count for the job, then a float, spare discs, a splash guard, and a supply you can keep dry. The twelve shelf prices run from about £12.99 to £129. Stars on the two largest samples do not prove a long life, and both of those files include a shock report.
An ultrasonic fogger in this UK set is a water mist maker. A ceramic disc vibrates under the surface and throws a cool cloud of fine droplets. The head is usually 24 V, or 45–48 V on the larger boards, and a mains adapter feeds it. Shoppers on amazon.co.uk buy one as a pond ornament, a Halloween cauldron effect, or a small humidifier for a tank or a glasshouse. Amazon files most of these ASINs under Pond Foggers. The same search word also pulls in sound repellers.
These twelve pages atomise water. None shows an HSE number. A biocidal product has to be labelled for the general public and used only for the purpose on the label. Workplace pesticide fogging is a contractor task under HSE guidance.
The large samples, 296 and 209 reviews, sit on single discs at £12.99 and £14.99. Walfront and two of the three 12-head kits have no star line. MUALROUS is 5.0 from two reviews, and neither text is from the United Kingdom.
Keep the adapter out of the water. On the 400 W blocks, IP67 sits next to “not submersible” or “do not immerse”. A shallow tray also spits. GlintBay says a container under the stated depth wets the surroundings, and reviews say that light head drifts.
A bowl or a cauldron needs one disc. A sheltered pond needs a float. A litres-per-hour claim for a glasshouse or a landscape is the 12-head boards at about £89.60, £97.99, and £129. Killing insects is the wrong job for every listing on this page. Single-disc bullets that state an output say about 300–400 ml/h: GlintBay 300 ml/h, Mxmoonant 350 ml/h, and Aobiforu at least 400 ml/h. The three 12-head listings say 8.4–9.0 L/h and up to about 9 m² indoors and 7 m² outdoors.
Listings that state a depth say roughly 3–5 cm above the unit on GlintBay, 6–7 cm on the MUALROUS board, or a buoy once the water is deeper than about 7–8 cm. A splash guard is the difference between mist and a wet table in the reviews. Prefer a stated UK plug, spare ceramic discs, and a key. Wandou states a UK plug and a low-water stop, and spare discs are not in the kit. The Mxmoonant £18.99 kits put a UK adapter, a float, a splash guard, and three 20 mm discs in the box.
Three typical situations, each with a recommendation from this comparison.
You want a single disc for a bowl, tank, or reptile humidity, at the lowest shelf price in this set, and you will unplug it before your hands go in the water. The Wandou 24 V head is £12.99, with a UK plug in the title and 3.9 from 296 reviews.
You already own the pot, and you want lights plus a splash guard with a large review file. The MOXTOYU disc is £14.99, with 12 colour-changing LEDs and 4.1 from 209 reviews. You supply the water container.
You want one head, a float, a splash guard, a UK adapter, and spare discs together. The Mxmoonant 350 ml/h kit is £18.99 and lists three 20 mm discs. The model field says no LED. It is 4.2 from 18 reviews.
The Wandou 24 V mist maker is the top pick: about £12.99, a UK plug in the title, a stated low-water stop, and 3.9 from 296 reviews, the largest sample in the twelve. The MOXTOYU disc at about £14.99 is the best value, with 4.1 from 209 reviews, 12 LEDs, and a splash guard, close to that shelf price and far ahead of the nine-review rows. Both files include early failures and a shock report if a hand is in the water while the unit is on. These listings throw water mist. They do not apply an insecticide.
MOXTOYU 12-LED mist maker
£14.99 with 4.1 from 209 reviews, lights and a splash guard, close to the cheapest disc and well ahead of the short review files.
