Pro Breeze 500ml Premium Mini Dehumidifier Review
By Priya Shah, reviewed by James Whitfield · Updated
Our verdict: The best budget dehumidifier for a small bathroom, wardrobe or caravan — not a replacement for a full-size unit, but excellent value for light, localised condensation control.
At a low price, the Pro Breeze 500ml is the dehumidifier UK buyers reach for when a full 12-20L compressor unit is overkill — a small bathroom, an en-suite, a wardrobe prone to a musty smell, or a caravan.

If you need to tackle actual damp or dry laundry rather than just take the edge off a small space, the Meaco MeacoDry Arete One 12L is built for that job.
Pro Breeze moisture extractor: pros and cons in detail
For the price, this is one of the most cost-effective ways to keep a small space dry: running costs are around 1p per hour, and Peltier technology means no compressor noise at all, making it safe to leave on overnight in a nursery. With over 37,000 Amazon ratings it is also one of the most-reviewed mini dehumidifiers sold in the UK. The catch is capacity — at only 250ml extracted per day it cannot handle a genuinely damp room or laundry drying, the small 500ml tank needs emptying every 1-2 days in a humid bathroom, and a minority of long-term owners report units failing after 12-18 months.

About Pro Breeze's damp extractor range
This is Pro Breeze's entry-level model, using Peltier (thermo-electric) cooling rather than a compressor. That's the key trade-off to understand: Peltier units are silent and cheap, but extract far less moisture per day than a compressor model like the Meaco Arete or Pro Breeze's own OmniDry range. Pro Breeze markets it explicitly for 'small spaces' — kitchen, bathroom, bedroom, caravan, wardrobe, office or garage — rather than as a whole-room damp solution.
With over 37,000 ratings on Amazon.co.uk at the time of writing, it's also one of the most bought and reviewed dehumidifiers in this category in the UK, which gives a reasonably reliable picture of long-term performance: mostly positive, with a recurring minority of reports of units failing after a year or so of use — in line with what you'd expect from a budget appliance at this price point.
Who this Pro Breeze moisture control unit is for, and how to use it at home
Best used in a small, enclosed space: a bathroom after showering, inside a wardrobe, or on a caravan window ledge. It performs best between 20-30°C and 60-80% relative humidity — outside that range, Peltier technology becomes noticeably less effective, so it's not the right choice for a cold garage or unheated space.
It is not designed to dry laundry or dehumidify a whole bedroom — for either of those jobs, a compressor unit like the Meaco Arete One 12L will do the job many times faster and more effectively, despite costing more upfront.
Empty the 500ml tank every 1-2 days in a genuinely humid bathroom; the auto shut-off and indicator light mean you won't overflow it if you forget.
Where to put it matters more than with a big compressor unit. Because the extraction rate is small, the unit only works on the air immediately around it. In a bathroom, stand it on a dry shelf or window ledge away from direct shower spray, with the door closed after you have finished so the moisture has nowhere else to go. In a wardrobe, leave the door shut, keep the unit on a stable base and give the vents a little clearance from clothes so air can circulate. In a caravan, a window ledge or worktop works well, as long as the unit stays level and the cable does not hang where it can be snagged.
Looking after it is simple. Empty the tank, rinse it with plain water and let it dry before refilling the unit's routine. A quick wipe of the outside and the air vents with a dry cloth stops dust building up and choking airflow, which matters on a small fan-driven appliance. Never tip water out through the air outlet, and keep the unit upright when you carry it. If it sits unused for a season, empty it fully first so the tank does not go stale.
Working out the running cost takes ten seconds: power draw multiplied by hours on, multiplied by your own electricity rate. The specs quote a very low hourly figure, and because it has no compressor, leaving it on for a few hours a day is unlikely to make a noticeable dent in a bill. Just remember that low running cost and low output go hand in hand. If a hygrometer shows the room still sitting well above the comfortable 40-60% band after a few days, the space needs a bigger machine, not a longer run time.
What UK buyers say about this Pro Breeze dehumidifier
This is Pro Breeze's best-selling mini dehumidifier, with tens of thousands of Amazon UK ratings averaging 4.5 stars. Reviewers on independent sites such as T3 and Quality Indoor Air describe it as small but genuinely effective for a wardrobe, caravan or bathroom window ledge, while cautioning that it is not a substitute for a full-size unit in a properly damp room.

Our verdict on this Pro Breeze moisture extractor: 4.1/5
Buy the Pro Breeze 500ml if you need light condensation control in a bathroom, wardrobe or caravan and want to spend as little as possible. If you're dealing with a genuinely damp room, mould, or want to dry laundry indoors, save up for a compressor unit like the Meaco Arete One 12L instead — this mini unit won't be powerful enough for that job.

A few extras that are genuinely useful with this model, not just upsells:
Digital room hygrometer
This mini unit has no digital display or built-in humidity sensor at all, so there's no way to tell from the machine itself whether a small bathroom or wardrobe is actually drying out, or whether 250ml a day simply isn't enough for the space. A cheap hygrometer left nearby gives a real relative-humidity reading before and after a few days of running it, which is the only reliable way to judge whether this model is coping or whether the room actually needs a full-size dehumidifier instead.

Frequently asked questions
Is this enough to stop mould in my bathroom?+
It helps with light, ongoing condensation control in a small bathroom, but if you already have visible mould or black spot, you'll get faster results from ventilation (an extractor fan) plus a proper compressor dehumidifier — this unit is best for prevention, not for tackling an existing mould problem.
How is this different from a full-size 12L or 20L dehumidifier?+
This uses Peltier technology (no compressor) which extracts around 250ml a day, versus 12,000-20,000ml a day for a compressor unit. It's silent and cheap but built for a small enclosed space, not a whole room or house.
Will it help dry laundry?+
Not effectively — its extraction rate is too low. For drying clothes indoors, a compressor dehumidifier with a dedicated laundry mode, like the Pro Breeze 20L OmniDry or Meaco Arete range, will dry a load in hours rather than days.
Is it safe to leave running overnight?+
Yes — Peltier units run cool and have no moving compressor, and this model has auto shut-off once the tank is full, which most owners specifically praise as safe for overnight use in a bedroom.
How quiet is the Pro Breeze 500ml in a bedroom or nursery?+
Peltier cooling has no compressor, so the noise comes mainly from a small fan, and buyers describe it as close to silent. That is why it is often chosen for bedrooms and nurseries. Bear in mind it only treats a small pocket of air, so it will not fix a damp bedroom on its own.
How do I clean the tank and keep the unit working properly?+
Empty the tank after each full cycle, rinse it with clean water and let it dry. Wipe the vents and casing with a dry cloth to clear dust. Avoid harsh chemicals and never submerge the unit. Regular emptying also stops stale water building up, which is the usual cause of a musty smell from small units.
Will it work in a cold garage, shed or unheated room?+
Not well. According to the specs the unit performs best at roughly 20-30°C and higher humidity, and Peltier technology loses effectiveness as temperatures drop. For a cold garage, outbuilding or unheated spare room, a compressor or desiccant model is a far better fit than this mini unit.
Who should not buy this dehumidifier?+
Skip it if you have visible mould across a wall, a whole damp room, or want to dry a load of washing indoors. At 250ml a day it is built for small enclosed spaces. For those jobs, look at the [Meaco Arete One 12L](/reviews/meaco-arete-one-12l/) or the larger [Meaco Arete Two 20L](/reviews/meaco-arete-two-20l/) instead.
