Pro Breeze 12L: the dehumidifier against mould in small flats

Prices in euros from Amazon.de, as of 11 June 2026. Prices and availability may differ on Amazon.co.uk.

By Seydhan Cakmak · Editor-in-chief · Updated: · AI-translated from the German original

Misted-up windows, damp corners, the musty smell in the bedroom: the Pro Breeze 12L is the right answer and the best all-rounder in the comparison. It draws up to 12 litres of water a day from the air, uses the built-in humidistat to hold a set target humidity (e.g. 50%) automatically, and in 38 dB sleep mode it is quiet enough to run in the bedroom at night. For unattended continuous operation a drain hose is included, so nobody has to empty the 1.8 litre tank any more. With 220 watts and auto-defrost, it reliably covers rooms up to around 20 m².

Pro Breeze 12L at a glance

In short: the Pro Breeze 12L scores 8,6/10 in our dehumidifier review (from €115). Biggest strength: quiet 38 dB sleep mode. Main compromise: tank of 1.8 L rather small.

All specifications come from manufacturer data sheets and the Amazon catalogue and were cross-checked before publication. The rating is an editorial overall assessment based on this data; we do not trial products ourselves.

Pro Breeze 12L: what works, what doesn't?

What works well

  • Quiet 38 dB sleep mode: Quiet Mark certified, can run in the bedroom at night
  • Humidistat holds target humidity: sets itself to 50 to 60% and switches by itself, no continuous running needed
  • Continuous drain hose included: for unattended operation in the cellar, never empty the tank again
  • Best value for money: full equipment for around €115

Points of criticism

  • Tank of 1.8 L rather small: without the hose, empty it daily at high humidity
  • Compressor audible at full operation: only sleep mode is really quiet
  • Output drops below ~15 °C: less effective in a cold cellar, typical of compressors

What does it cost to run?

At a maximum of 220 W power draw, an hour of use at 35 ct/kWh (German electricity price) costs about 8 cents. Eight hours of continuous running (e.g. overnight) therefore cost about 62 cents.

Calculation basis: 35 ct/kWh (German electricity price, 2026, rounded). Values from the manufacturer data sheet; actual costs depend on use and tariff.

Build quality & everyday use

What carries the Pro Breeze 12L in everyday use: Quiet 38 dB sleep mode (Quiet Mark certified, can run in the bedroom at night) and Humidistat holds target humidity (sets itself to 50 to 60% and switches by itself, no continuous running needed). We have to be honest about the weaknesses: tank of 1.8 L rather small, so without the hose you empty it daily at high humidity.

If you set the device up to save space, allow ventilation clearance of at least 5 cm at the sides and 10 cm at the rear, otherwise the compressor may overheat.

“Pro Breeze 12L Dehumidifier: quiet 38 dB sleep mode and humidistat holds target humidity, and the trade-off is the rather small 1.8 L tank. At 8.6/10 a safe choice from €115.”

Frequently asked questions about the Pro Breeze 12L

Does a dehumidifier really help against mould?
Yes. Mould needs a relative humidity above about 60% to germinate. A dehumidifier like the Pro Breeze 12L keeps humidity permanently at 50 to 55% via the humidistat, so below the critical threshold. That tackles the cause, not just the growth, and is much cheaper than mould remediation.
How much dehumidifying capacity do I need for my flat?
Rule of thumb: for a bedroom or small flat up to ~20 m², 10 to 12 L/day is enough; for larger rooms or damp cellars, rather 16 to 20 L/day. The Pro Breeze 12L is designed for up to 20 m² and is therefore the right all-rounder for the typical small flat.
Is the Pro Breeze 12L quiet enough for the bedroom?
In sleep mode it runs at 38 dB (Quiet Mark certified), which is quieter than most compressor dehumidifiers and quite bearable at night. If you want absolute silence, additionally reach for a quiet Peltier mini such as the Pro Breeze Mini, though it draws far less water.
How much electricity does the Pro Breeze 12L use?
It draws 220 watts. At, say, 6 hours of operation a day, that is around 1.3 kWh daily or roughly €0.40. Through the humidistat it only runs when humidity is too high, though, so often much less. Compared with mould remediation, the electricity costs are negligible.

Verdict: is the Pro Breeze 12L worth it?

A safe choice in its class: if you can live with the rather small 1.8 L tank, from €115 you get mainly one thing: a quiet 38 dB sleep mode. It suits best: small flats up to 20 m².
